Fluid collection devices and methods of manufacturing same

[0001] This application is a U.S. Nationalization of PCT International Application No. PCT/US2021/045188 filed on Aug. 9, 2021, which claims priority to U.S. Provisional Patent Application No. 63/064,017 filed on Aug. 11, 2020, the disclosure of each of which is incorporated herein, in their entirety, by this reference.

[0002] An individual may have limited or impaired mobility such that typical urination processes are challenging or impossible. For example, the individual may have surgery or a disability that impairs mobility. In another example, the individual may have restricted travel conditions such as those experienced by pilots, drivers, and workers in hazardous areas. Additionally, fluid collection from the individual may be needed for monitoring purposes or clinical testing.

[0003] Bed pans and urinary catheters, such as a Foley catheter, can be used to address some of these circumstances. However, bed pans and urinary catheters have several problems associated therewith. For example, bed pans can be prone to discomfort, pressure ulcers, spills, and other hygiene issues. Urinary catheters be can be uncomfortable, painful, and can cause urinary tract infections. Recently, non-invasive fluid collection devices have been developed for use with immobile and/or limited mobility individuals. By non-invasive, it is meant that the catheter may be placed externally (e.g., outside an opening of the urethra).

[0004] Due to the nature of bodily fluids, fluid collection devices may need to be sterilized and/or replaced frequently. Accordingly, improved manufacturing techniques of fluid collection devices to ensure quality consistency and/or reduce cost may be desired.

[0020] Features from any of the disclosed embodiments may be used in combination with one another, without limitation. In addition, other features and advantages of the present disclosure will become apparent to those of ordinary skill in the art through consideration of the following detailed description and the accompanying drawings.

[0052] Embodiments disclosed herein are directed to fluid collection devices and methods of manufacturing same. The fluid collection devices disclosed herein are configured to collect fluids from an individual. The fluids collected by the fluid collection devices can include urine. The fluids collected by the fluid collection devices can also include at least one of vaginal discharge, penile discharge, reproductive fluids, blood, sweat, or other bodily fluids.

[0053] The fluid collection devices may include one or more components for drawing (e.g., wicking) fluid from a wearer and/or a surface of the fluid collection device into an interior of the fluid collection device. In some embodiments, the fluid collection devices may include a fluid permeable body for wicking fluid into the fluid collection device. In some embodiments, the fluid permeable body may include a fluid permeable membrane at least partially surrounding a support. In some embodiments, the support may be a fluid permeable support. In some embodiments, the fluid collection device may include a fluid permeable support without a fluid permeable membrane. The support alone or in combination with the fluid permeable membrane may direct fluids to an interior of the fluid collection device where the fluid may be removed from the fluid collection device.

[0054] FIG. 1A is an isometric view of a fluid collection device 100 according to at least one embodiment of the disclosure. The fluid collection device 100 is an example of a female fluid collection device 100 that is configured to receive fluids from a female wearer. The fluid collection device 100 includes a fluid impermeable barrier 102 having a first end region 125 and a second end region 127. The first end region 125 may include an aperture 124 for accepting a conduit 108 that may couple the fluid collection device 100 to a vacuum source. The fluid impermeable barrier 102 at least partially defines a chamber 104 (e.g., interior region, shown in FIG. 1B) and includes an inward border or edge 129 defining an opening 106. The fluid impermeable barrier 102 may be substantially cylindrical in shape between the first end region 125 and the second end region 127. The opening 106 is formed in and extends through the fluid impermeable barrier 102, thereby enabling fluids to enter the chamber 104 from outside of the fluid collection device 100. The opening 106 can be configured to be positioned adjacent to a female urethra in some applications.

[0055] In the fluid collection device 100 is configured to receive fluids into the chamber 104 via the opening 106. For example, the opening 106 can exhibit an elongated shape that is configured to extend from a first location below the urethral opening (e.g., at or near the anus or the vaginal opening) to a second location above the urethral opening (e.g., at or near the clitoris or the pubic hair). The opening 106 can exhibit an elongated shape since the space between the legs of a female wearer is relatively small when the legs of the female wearer are closed, thereby only permitting the flow of the fluids along a path that corresponds to the elongated shape of the opening 106. For example, the opening 106 can extend longitudinally along the fluid impermeable barrier. The opening 106 in the fluid impermeable barrier 102 can exhibit a width that is measured transverse to the longitudinal direction and may be at least about 10% of the circumference of the fluid collection device 100, such as about 25% to about 50%, about 40% to about 60%, about 50% to about 75%, about 65% to about 85%, or about 75% to about 100% of the circumference of the fluid collection device 100. The opening 106 can exhibit a width that is greater than 50% of the circumference of the fluid collection device 100 since a vacuum (e.g., suction) through a conduit 108 pulls the fluid into the conduit 108. In some embodiments, the opening 106 may be vertically oriented (e.g., having a major axis parallel to the longitudinal axis of the device 100). In some embodiments (not shown), the opening 106 may be horizontally oriented (e.g., having a major axis perpendicular to the longitudinal axis of the device 100). In some embodiments, the inward border or edge 129 of the fluid impermeable barrier 102 defines the opening 106. The edge 129 can include two opposing arced portions, the arcs following the outer circumference or periphery of the substantially cylindrical fluid impermeable barrier 102.

[0056] The fluid impermeable barrier 102 may also temporarily store the fluids in the chamber 104. As such, the fluid impermeable barrier 102 substantially prevents the fluids from exiting the portions of the chamber 104 that are spaced from the opening 106. The fluid impermeable barrier 102 may be flexible, allowing the fluid collection device 100 to bend or curve when positioned against the body of a wearer. For example, the fluid impermeable barrier 102 can be formed of any suitable fluid impermeable materials, such as a fluid impermeable polymer (e.g., silicone, polypropylene, polyethylene, polyethylene terephthalate, a polycarbonate, etc.), polyurethane films, TPE, oil, another suitable material, or combinations thereof. In some embodiments, the fluid impermeable barrier 102 can include one or more thermoplastic elastomers. The one or more thermoplastic elastomers may be combined with at least one of silicone and oil. In many embodiments, the fluid impermeable barrier 102 can include a composition having at least silicone and oil therein.

[0057] The fluid collection device 100 can include a fluid permeable body 120 or layer disposed in the chamber 104. The fluid permeable body 120 can cover or extend across at least a portion (e.g., all) of the opening 106. The fluid permeable body 120 can be configured to wick fluid away from the opening 106, thereby preventing the fluid from escaping the chamber 104. The fluid permeable body 120 also can wick the fluid generally towards an interior of the chamber 104, as discussed in more detail below. A portion of the fluid permeable body 120 can define a portion of an outer surface of the fluid collection device 100. Specifically, the portion of the fluid permeable body 120 defining the portion of the outer surface of the fluid collection device 100 can be the portion of the fluid permeable body 120 exposed by the opening 106 defined by the fluid impermeable barrier 102. At least a portion of the fluid permeable body 120 exposed by the opening 106 may contact the wearer.

[0058] The fluid permeable body 120 can include any material that can wick the fluid. The permeable properties referred to herein can be wicking, capillary action, diffusion, or other similar properties or processes, and are referred to herein as “permeable” and/or “wicking.” Such “wicking” may exclude absorption into the wicking material (e.g., retention of fluid by the material). Put another way, substantially no absorption of fluid in the material may take place after the material is exposed to the fluid and removed from the fluid for a time. While no absorption is desired, the term “substantially no absorption” may allow for nominal amounts of absorption of fluid into the wicking material (e.g., absorbency), such as less than about 10 wt % of the dry weight of the wicking material, less than about 7 wt %, less than about 5 wt %, less than about 3 wt %, less than about 2 wt %, less than about 1 wt %, or less than about 0.5 wt % of the dry weight of the wicking material.

[0059] The fluid permeable body 120 can enable the fluid to flow generally towards a reservoir 122 (shown in FIGS. 2A and 2B) of void space formed within the chamber 104. For example, the fluid permeable body 120 can include a porous or fibrous material, such as spun nylon fibers or a hydrophilic polyolefin. Examples of polyolefin that can be used in the fluid permeable body 120 include, but are not limited to, polyethylene, polypropylene, polyisobutylene, ethylene propylene rubber, ethylene propylene diene monomer, or combinations thereof. In some embodiments, the porous or fibrous material can be extruded into a substantially cylindrically shape to fit within the chamber 104 of the fluid impermeable barrier 102. The fluid permeable body 120 can be manufactured according to various manufacturing methods, such as molding, extrusion, or sintering as will be described in more detail with reference to FIGS. 4-19.

[0060] In some embodiments, during use, the fluid permeable body 120 extends from the conduit 108 to interface the fluid impermeable barrier 102 and the opening 106. In some embodiments, a majority of the outer surface 109 (shown in FIG. 1B and FIG. 3) of the fluid permeable body 120 interfaces with an inner surface 103 (shown in FIG. 1B) of the fluid impermeable barrier 102. In other embodiments, a majority of the outer surface 109 may be exposed by the opening 106 of the fluid impermeable barrier 102. In some embodiments, at least a portion of the fluid permeable body 120 extends continuously between the opening 106 and the reservoir 122. In some embodiments, the fluid collection device 100 is free from a seal or cushioning ring on the inward edge 129 defining the opening 106.

[0061] FIG. 3 is a cross-sectional view of the fluid collection device 100 taken along line 3-3 of FIG. 1A. As shown in FIG. 3, the fluid permeable body 120 can include a fluid permeable membrane 340 covering or wrapped around at least a portion of a fluid permeable support 342, with both the fluid permeable membrane 340 and the fluid permeable support 342 being disposed at least partially in the chamber 104. The fluid permeable membrane 340 can cover or extend across at least a portion (e.g., all) of the opening 106. In some embodiments, at least one of the fluid permeable membrane 340 or the fluid permeable support 342 include nylon configured to wick fluid away from the opening 106. The material of the fluid permeable membrane 340 and the fluid permeable support 342 also can include natural fibers. In such examples, the material may have a coating to prevent or limit absorption of fluid into the material, such as a water repellent (e.g., hydrophobic) coating.

[0062] The fluid permeable membrane 340 can include any material that can wick the fluid. For example, the fluid permeable membrane 340 can include fabric, such as a gauze (e.g., a silk, linen, polymer based materials such as polyester, or cotton gauze), another soft fabric (e.g., jersey knit fabric or the like), or another smooth fabric (e.g., rayon, satin, or the like). Forming the fluid permeable membrane 340 from gauze, soft fabric, and/or smooth fabric can improve comfort of the wearer, for example by reducing chaffing of the wearer's skin caused by the fluid collection device 100. In some embodiments, the fluid permeable body 120 includes a fluid permeable support 342 including a porous nylon structure (e.g., spun nylon fibers) and a fluid permeable membrane 340 including gauze.

[0063] The fluid permeable body 120 is disposed within a chamber 104 (shown in FIGS. 2A and 2B) of the fluid impermeable barrier 102 of the fluid collection device 100 and is exposed to the urethra of the user 150 through the opening 106 in the fluid collection device 100. Fluids received in the chamber 104 of the fluid collection device 100 from the urethra can be removed through the conduit 108.

[0064] FIG. 2A is a cross-sectional view of the fluid collection device 100 taken along line 2-2 of FIG. IA. The fluid collection device 100 also includes conduit 108 that is at least partially disposed in the chamber 104. The conduit 108 (e.g., a tube) includes an inlet 110 at a second end region 127 of the fluid impermeable barrier 102 and an outlet 112 at a first end region 125 of the fluid impermeable barrier 102 positioned downstream from the inlet 110. The conduit 108 provides fluid communication between an interior region of the chamber 104 and a fluid storage container (not shown) and/or a portable vacuum source (not shown). For example, the conduit 108 may directly or indirectly fluidly couple the interior region of the chamber 104 and/or the reservoir 122 with the fluid storage container or the portable vacuum source.

[0065] In the illustrated embodiment, the fluid permeable body 120 defines a bore 202 extending through the fluid permeable body 120 from a first body end 121 of the fluid permeable body 120 to a second body end 123 of the fluid permeable body 120 distal to the first body end 121. In other embodiments, the bore 202 extends only partially into the fluid permeable body from the first body end 121 of the fluid permeable body 120.

[0066] In the illustrated embodiment, the conduit 108 is at least partially disposed in the chamber 104 and interfaces at least a portion of the bore 202 of the fluid permeable body 120. For example, the conduit 108 may extend into the fluid impermeable barrier 102 from the first end region 125 (e.g., proximate to the outlet 112) and may extend through the bore 202 to the second end region 127 (e.g., opposite the first end region 125) to a point proximate to a reservoir 122 such that the inlet 110 is in fluid communication with the reservoir 122. For example, in the illustrated embodiment, the inlet 110 is positioned in the reservoir 122. However, in other embodiments such as in FIG. 2B, the inlet 110 may be positioned flush with or behind an end of the fluid permeable body 120 that partially defines the reservoir 122. The fluid collected in the fluid collection device 100 may be removed from the interior region of the chamber 104 via the conduit 108. The conduit 108 may include a flexible material such as plastic tubing (e.g., medical tubing). Such plastic tubing may include a thermoplastic elastomer, polyvinyl chloride (PVC), ethylene vinyl acetate, polytetrafluoroethylene, etc., tubing. In some embodiments, the conduit 108 may include silicone or latex.

[0067] The fluid impermeable barrier 102 can store fluids in a reservoir 122 therein. The reservoir 122 is an unoccupied portion of the chamber 104 and is void of other material. In some embodiments, the reservoir 122 is defined at least partially by the fluid permeable body 120 and the fluid impermeable barrier 102. The reservoir 122 may be disposed in any portion of the interior region of the chamber 104. For example, the fluid reservoir 122 may be positioned in the second end region 127 of the chamber 104. In the illustrated embodiment, the reservoir 122 is defined by the second body end 123 of the fluid permeable body 120 and the second end region 127 of the fluid impermeable barrier 102.

[0068] In an embodiment, the reservoir 122 can be located at the portion of the chamber 104 that is closest to the inlet 110 (e.g., the second end 127 region). However, the reservoir 122 can be located at different locations in the chamber 104 (e.g., the first end 125 region, a portion of the chamber 104 away from the opening 106). In some embodiments, the conduit 108 may extend through the fluid impermeable barrier to the reservoir 122 without extending through the fluid permeable body 120. Accordingly, in these and other embodiments, the fluid permeable body 120 may be free from the bore 202. In another embodiment, the fluid collection device 100 can include multiple reservoirs, such as a first reservoir that is located at the portion of the chamber of the chamber 104 that is closest to the inlet 110 (e.g., second end region) and a second reservoir that is located at the portion of the of the chamber 104 that is closest to the outlet 112 (e.g., first end region). In another example, the fluid permeable body 120 is spaced from at least a portion of the conduit 108 and the reservoir 122 can be the space between the fluid permeable body 120 and the conduit 108.

[0069] The fluid impermeable barrier 102 can define an aperture 124 sized to receive the conduit 108 (e.g., at least one tube). The at least one conduit 108 can be disposed in the chamber 104 via the aperture 124. The apertures 124 can be configured to form an at least substantially fluid tight seal against the conduit 108 or the at least one tube thereby substantially preventing the fluids from escaping the chamber 104.

[0070] When secured to the fluid collection device 100, the conduit 108 is configured to provide fluid communication with and at least partially extend between one or more of a fluid storage containers (not shown) and a portable vacuum source (not shown). For example, the conduit 108 may be configured to be fluidly coupled to and at least partially extend between one or more of the fluid storage containers and the portable vacuum source. In an embodiment, the conduit 108 is configured to be directly connected to the portable vacuum source. In such an example, the conduit 108 can extend from the fluid impermeable barrier 102 by at least one foot, at least two feet, at least three feet, or at least six feet. In another example, the conduit 108 is configured to be indirectly connected to at least one of the fluid storage container or the portable vacuum source.

[0071] The inlet 110 and the outlet 112 are configured to provide fluid communication (e.g., directly or indirectly) between the portable vacuum source and the chamber 104 (e.g., the reservoir 122). For example, the inlet 110 and the outlet 112 of the conduit 108 may be configured to directly or indirectly fluidly couple the portable vacuum source to the reservoir 122. In an embodiment, the inlet 110 and/or the outlet 112 can form a male connector. In another example, the inlet 110 and/or the outlet 112 can form a female connector. In an embodiment, the inlet 110 and/or the outlet 112 can include ribs that are configured to facilitate secure couplings. In an embodiment, the inlet 110 and/or the outlet 112 can form a tapered shape. In an embodiment, the inlet 110 and/or the outlet 112 can include a rigid or flexible material.

[0072] As the portable vacuum source applies a vacuum/suction in the conduit 108, the fluid(s) in the chamber 104 (e.g., such as in the reservoir 122 positioned at the first end region 125, the second end region 127, or other intermediary positions within the chamber 104) may be drawn into the inlet 110 and out of the fluid collection device 100 via the conduit 108.

[0073] In an embodiment, the conduit 108 is configured to be at least insertable into the chamber 104. In such an embodiment, the conduit 108 can include one or more markers 131 (shown in FIG. 1A) on an exterior thereof that are configured to facilitate insertion of the conduit 108 into the chamber 104. For example, the conduit 108 can include one or more markings thereon that are configured to prevent over or under insertion of the conduit 108, such as when the conduit 108 defines an inlet 110 that is configured to be disposed in or adjacent to the reservoir 122. In another embodiment, the conduit 108 can include one or more markings thereon that are configured to facilitate correct rotation of the conduit 108 relative to the chamber 104. In an embodiment, the one or more markings can include a line, a dot, a sticker, or any other suitable marking. In examples, the conduit 108 may extend into the fluid impermeable barrier 102 from the first end 125 region (e.g., proximate to the outlet 112) and may extend to the second end 127 region (e.g., opposite the first end region) to a point proximate to the reservoir 122 such that the inlet 110 is in fluid communication with the reservoir 122. In some embodiments (not shown), the conduit 108 may enter the second end 127 region and the inlet 110 may be disposed in the second end 127 region (e.g., in the reservoir 122). The fluid collected in the fluid collection device 100 may be removed from the interior region of the chamber 104 via the conduit 108. The conduit 108 may include a flexible material such as plastic tubing (e.g., medical tubing) as disclosed herein. In some examples, the conduit 108 may include one or more portions that are resilient, such as to by having one or more of a diameter or wall thickness that allows the conduit to be flexible.

[0074] As disclosed herein, embodiments of fluid collection devices and components thereof may be manufactured by a variety of methods. For example, the fluid collection device 100 including the fluid impermeable barrier 102 and the fluid permeable body 120 may be manufactured by a variety of methods. Certain manufacturing methods may automate one or more fabrication and/or assembly steps. In some applications, this may increase consistency, reduce time, and/or improve sterility. Certain manufacturing methods may reduce or eliminate one or more components of the fluid collection device (e.g., the fluid permeable membrane 140 of the fluid permeable body 120). In some applications, this may reduce cost, permit additional automation, and/or reduce time of manufacture. Certain manufacturing methods may add components to the fluid collection device. In some applications, this may make the fluid collection device easier to assemble, couple to a vacuum source and/or external fluid collection reservoir, and/or otherwise put into use. Certain manufacturing methods may alter a shape, arrangement, and/or configuration of one or more components of the fluid collection device. In some applications, this may permit additional automation in manufacturing, reduce cost, improve performance of the fluid collection device, and/or make the fluid collection device easier to assemble or put in use.

[0075] Various manufacturing methods of fluid collection devices and components thereof will now be described in more detail with reference to FIGS. 4-19.

[0076] FIGS. 4A-4D illustrate the operation of a tube cutting apparatus according to at least one embodiment of the disclosure. In some embodiments, the tube cutting apparatus 400 may be used to reduce or eliminate manual cutting of tubing used for a conduit of a fluid collection device, such as conduit 108. In some embodiments, the tube cutting apparatus 400 may be used to reduce or eliminate manual cutting of a tube of fluid wicking material for a fluid permeable body, such as fluid permeable membrane 340 and/or support 342 of fluid permeable body 120.

[0077] The tube cutting apparatus 400 may include a reel 402 around which is wrapped a length of tubing 404. In some embodiments, the tubing 404 may be tubing associated with a conduit of a fluid collection device, a fluid permeable membrane of the fluid collection device, and/or a support of the fluid collection device. The tube cutting apparatus 400 may further include a set of motorized rollers 406 and a second set of motorized rollers 408. The sets of motorized rollers 406, 408 may be mounted to a housing 424. In some embodiments, the housing 424 may include motors for rotating the motorized rollers 406, 408. The tube cutting apparatus 400 may further include a stop 410 mounted to the housing 424. The motorized rollers 406, 408 may include metal, plastic, or a combination thereof. For example, the motorized rollers 406, 408 may include metal with a plastic non-slip coating to prevent the tubing 404 from slipping between the motorized rollers 406, 408.

[0078] As shown in FIG. 4A, the motorized rollers 406 may rotate in opposing directions as indicated by arrows 412 to draw the tubing 404 off the reel 402 and between the motorized rollers 406. The tubing 404 may be drawn along a direction indicated by arrow 414 to the motorized rollers 408. The motorized rollers 408 may rotate in opposing directions as indicated by arrows 416 to draw the tubing 404 between the motorized rollers 408 to the stop 410. In some embodiments, the movement of the motorized rollers 406, 408 may cause the reel 402 to rotate as indicated by arrows 418. In other embodiments, the reel 402 may also be motorized.

[0079] In some embodiments, the stop 410 includes a sensor that detects when the tubing 404 contacts the stop 410. Examples of suitable sensors include, but are not limited to, a spring switch, pressure pad, optical detector). In some embodiments, the motorized rollers 406 and/or 408 may include torque sensors. The torque may increase when the tubing 404 contacts the stop 410. When the sensor of the stop 410 and/or the torque sensors indicate the tubing 404 is in contact with the stop 410, the motorized rollers 406, 408 may stop rotating.

[0080] The tube cutting apparatus 400 may further include a blade (e.g., sharp edge) 420 as shown in FIG. 4B. The blade 420 may cut the tubing 404 to length. The location of the blade 420 may be based, at least in part, on a desired length of a cut tube. In some embodiments, the position of the blade 420 may be adjustable. In some embodiments, the blade 420 may include metal, a ceramic, and/or a combination thereof. In some embodiments, the blade 420 may be replaced by an alternative cutting element such as a laser, ultrasonic cutter, electric arc, etc. As shown in FIG. 4C, the cut tubing 404A may be removed from the tube cutting apparatus 400. In some embodiments, the cut tubing 404A may be placed in a collection container (not shown). In some embodiments, the cut tubing 404A may fall as indicated by arrow 422, due to gravity. In other embodiments, the cut tubing 404A may be ejected from the tube cutting apparatus 400, for example, by a piston (not shown). In some embodiments, the cut tubing 404A may be manually removed from the tube cutting apparatus 400 by a user. Once the cut tubing 404A is removed from the tube cutting apparatus 400, the next length of tubing 404 can be drawn through the motorized rollers 406, 408 to the stop 410 as shown in FIG. 4D.

[0081] In some embodiments, the housing 424 may further include a processor and/or other circuitry for controlling the various components of the tube cutting apparatus 400. For example, the speed of the motorized rollers 406, 408, stopping the motorized rollers 406,408 responsive to the tubing 404 contacting the stop 410, and actuating the blade 420. In some embodiments, the operation of the tube cutting apparatus 400 illustrated in FIGS. 4A-4D is completely automated. In other embodiments, some or all of the actions may be initiated by a user by actuating one or more buttons, switches, foot pedals, etc. For example, the user may push a foot pedal to actuate the blade 420 whereas the actions of the motorized rollers 406,408 may be automated. In some embodiments, the tube cutting apparatus 400 may further include a graphical user interface (e.g., a touch screen, a conventional screen in combination with a keypad and/or trackpad) for the user to initiate some or all of the actions and/or configure the tube cutting apparatus 400 for fully automated operation. For example, a user may set a speed of the motorized rollers 406, 408, a distance between rollers of a set of the motorized rollers 406, 408, and/or a location of the blade 420 between the two sets of motorized rollers 406, 408.

[0082] FIG. 5 is a flow chart of a method according to at least one embodiment of the disclosure. The method 500 may be performed, at least in part, by a tube cutting apparatus, such as tube cutting apparatus 400 in some embodiments. The method 500 may be used to manufacture at least a portion of a fluid collection device disclosed herein, for example, fluid collection device 100.

[0083] At block 502, “drawing a length of tubing through a first set of motorized rollers by rotating rollers of the first set of motorized rollers in opposing directions” may be performed. At block 504, “drawing the length of tubing through a second set of motorized rollers by rotating rollers of the second set of motorized rollers in opposing directions” may be performed. In some embodiments, blocks 502 and 504 may be performed simultaneously. In some embodiments, block 502 may be initiated first and continue while block 504 is initiated. 6. In some embodiments, the length of tubing comprises a fluid impermeable tubing. In some embodiments, the fluid impermeable tubing comprises polyvinyl chloride. In some embodiments, the length of tubing comprises a fluid permeable material. In some embodiments, the fluid permeable material comprises an open cell foam.

[0084] At block 506, “stopping rotation of the first set of motorized rollers and the second set of motorized rollers when an end of the length of tubing contacts a stop” may be performed. In some embodiments, when the end of the length of tubing contacts the stop may be detected with a sensor included with the stop. In some embodiments, when the end of the length of tubing contacts the stop may be detected when a torque on at least one of the first set of motorized rollers or the second set of motorized rollers increases.

[0085] At block 508, “cutting the length of tubing at a location between the first set of motorized rollers and the second set of motorized rollers” may be performed. In some embodiments cutting the tubing may include actuating a blade, such as blade 420. In other embodiments, cutting the tubing may include activating a laser, an ultrasound cutter, and/or other cutting implement.

[0086] At block 510, “ejecting a cut portion of the length of tubing from a tube cutting apparatus including the first set and the second set of motorized rollers” may be performed. In some embodiments, ejecting the cut portion of the length of tubing may include actuating a piston.

[0087] At block 512, “inserting the length of tubing at least partially into a chamber of a fluid impermeable barrier of the fluid collection device” may be performed. For example, the tubing may inserted into chamber 104 of fluid collection device 100.

[0088] FIGS. 6A-6D illustrate the operation of a tube cutting apparatus according to at least one embodiment of the disclosure. In some embodiments, the tube cutting apparatus 600 may be used to reduce or eliminate manual cutting of tubing used for a conduit of a fluid collection device, such as conduit 108. In some embodiments, the tube cutting apparatus 600 may be used to reduce or eliminate manual cutting of a tube of fluid wicking material for a fluid permeable body, such as fluid permeable membrane 340 and/or support 342 of fluid permeable body 120. In some embodiments, the tube cutting apparatus 600 may be used to reduce manual insertion of the conduit into the fluid permeable body.

[0089] The tube cutting apparatus 600 may include a reel 602 around which is wrapped a length of tubing 604. In some embodiments, the tubing 604 may be tubing associated with a conduit of a fluid collection device, which may include a fluid impermeable material. The tube cutting apparatus 600 may include one or more sets of motorized rollers 606. The sets of motorized rollers 606 may be mounted to a housing (not shown), similar to housing 424 in FIGS. 4A-D. The tube cutting apparatus may include another reel 608 around which is wrapped another length of tubing 610. The tubing 610 may be tubing associated with a fluid permeable body of the fluid collection device. For example, the tubing 610 may be used to implement the support and/or fluid permeable membrane of the fluid permeable body. The tube cutting apparatus 600 may include one or more additional sets of motorized rollers 612. The motorized rollers 606, 612 may include metal, plastic, or a combination thereof. For example, the motorized rollers 606, 612 may include metal with a plastic non-slip coating to prevent the tubing 604, 610 from slipping between the motorized rollers 606, 612.

[0090] The tube cutting apparatus 600 may include a housing 614 which may have an opening 620 at a first end 622 (indicated in FIG. 6B) sized to accept the tubing 604 therein and an opening 624 at a second end 626 opposite the first end 622 sized to accept the tubing 610. In some embodiments, the opening 624 may be larger than the opening 620. The housing 614 may further include a stop 616 (indicated in FIG. 6A). In some embodiments, the stop 616 may be a ledge formed by the opening 620 meeting the opening 624 when opening 620 is smaller than opening 624.

[0091] As shown in FIG. 6A, the motorized rollers 606 may rotate in opposing directions as indicated by arrows 628 to draw the tubing 604 off the reel 602 and between the motorized rollers 606. The tubing 604 may be drawn along a direction indicated by arrow 630 through the opening 620 of the housing 614. In some embodiments, the movement of the motorized rollers 606 may cause the reel 602 to rotate as indicated by arrows 630. In other embodiments, the reel 602 may also be motorized.

[0092] The motorized rollers 612 may rotate in opposing directions as indicated by arrows 632 to draw the tubing 610 between the motorized rollers 612 through the opening 624 of the housing 614 to the stop 616. In some embodiments, the movement of the motorized rollers 612 may cause the reel 608 to rotate as indicated by arrows 634. In other embodiments, the reel 608 may also be motorized.

[0093] In some embodiments, the stop 616 may include a sensor that detects when the tubing 610 contacts the stop 616. Examples of suitable sensors include, but are not limited to, a spring switch, pressure pad, optical detector). In some embodiments, the housing 614 may include sensors 618 (indicated in FIG. 6B) along the opening 624 to detect the tubing 610. In some embodiments, the motorized rollers 612 may include torque sensors. The torque may increase when the tubing 610 contacts the stop 616. When the sensor of the stop 616, sensors 618, and/or the torque sensors indicate the tubing 610 is in contact with the stop 616, the motorized rollers 612 may stop rotating.

[0094] As shown in FIG. 6B, the motorized rollers 606 may continue to rotate until a portion (e.g., length) of the tubing 604 (tubing 604′) is inserted through the tubing 610. Thus, the tubing 610 may include a bore (e.g., similar to bore 202) sized to accept the tubing 604 therein. In some embodiments, the motorized rollers 606 may include encoders that detect when a desired length of the tubing 604 has been inserted into the tubing 610. In some embodiments, the sensors 618 may detect when the desired length of the tubing 604 has been inserted into the tubing 610. When the encoders and/or sensors 618 indicate the desired length of tubing 604 has been inserted into the tubing 610, the motorized rollers 606 may stop rotating.

[0095] The tube cutting apparatus 600 may include a blade (e.g., sharp edge) 636 as shown in FIG. 6C. The blade 636 may cut the tubing 604 to a desired length. The length may be such that the tubing 604 extends a distance outside the tubing 610. The location of the blade 636 may be based, at least in part, on a desired length of the tubing 604. The tube cutting apparatus 600 may include a blade 638 for cutting the tubing 610. In some embodiments, the blade 638 may be positioned to cut the tubing 610 flush with the portion of tubing 604′. In some embodiments, the blade 638 may be positioned such that tubing 610 extends beyond the portion of tubing 604′. In some embodiments, the position of the blade 636 and/or 638 may be adjustable. In some embodiments, the blade 636 and/or 638 may include metal, a ceramic, and/or a combination thereof. In some embodiments, the blade 636 and/or 638 may be replaced by an alternative cutting element such as a laser, ultrasonic cutter, electric arc, etc. In some embodiments, the tube cutting apparatus 600 may include a single blade that changes position to cut both tubes.

[0096] As shown in FIG. 6D, the cut tubing 640 may be removed from the tube cutting apparatus 600. In some embodiments, the cut tubing 640, including tube 604A and tube 610A, may be placed in a collection container (not shown). In some embodiments, the cut tubing 640 may fall as indicated by arrow 642, due to gravity. In other embodiments, the cut tubing 640 may be ejected from the tube cutting apparatus 600, for example, by a piston (not shown). In some embodiments, the cut tubing 640 may be manually removed from the tube cutting apparatus 600 by a user. In some embodiments, the cut tubing 640 may be inserted into a fluid impermeable barrier of a fluid collection device. For example, the cut tubing 640 may be inserted into a chamber (e.g., chamber 104) through an opening (e.g., opening 106) of the fluid impermeable barrier such that the tubing 604 pass through an aperture at an end of the chamber (e.g., aperture 124) and the tubing 610 substantially fills the opening of the chamber.

[0097] Similar to the tube cutting apparatus 400, in some embodiments, tube cutting apparatus 600 may further include a processor and/or other circuitry for controlling the various components of the tube cutting apparatus 600. For example, the speed of the motorized rollers 606, 612, stopping the motorized rollers 606, 612 responsive to the tubing 610 contacting the stop 616, and actuating the blades 636, 638. In some embodiments, the operation of the tube cutting apparatus 600 illustrated in FIGS. 6A-4D is completely automated. In other embodiments, some or all of the actions may be initiated by a user by actuating one or more buttons, switches, foot pedals, etc. For example, the user may push a foot pedal to actuate the blades 636, 638 whereas the actions of the motorized rollers 606, 612 may be automated. In some embodiments, the tube cutting apparatus 600 may further include a graphical user interface (e.g., a touch screen, a conventional screen in combination with a keypad and/or trackpad) for the user to initiate some or all of the actions and/or configure the tube cutting apparatus 600 for fully automated operation. For example, a user may set a speed of the motorized rollers 606, 612, a distance between rollers of a set of the motorized rollers 606, 612, and/or locations of the blades 636, 638.

[0098] FIG. 7 is a flow chart of a method according to at least one embodiment of the disclosure. The method 700 may be performed, at least in part, by a tube cutting apparatus, such as tube cutting apparatus 600 in some embodiments. The method 700 may be used to manufacture at least a portion of a fluid collection device disclosed herein, for example, fluid collection device 100.

[0099] At block 702, “drawing a first tube into a tube cutting apparatus from a first direction by rotating a first set of motorized rollers in opposing directions until the first tube contacts a stop” may be performed. In some embodiments, the first tube may include a fluid permeable material such as an open cell foam.

[0100] At block 704, “drawing a second tube into the tube cutting apparatus from a second direction by rotating a second set of motorized rollers in opposing directions, wherein drawing the second tube into the tube cutting apparatus causes at least a portion of the second tube to be inserted into the first tube” may be performed. In some embodiments, the second tube may include a fluid impermeable material such as PVC.

[0101] At block 706, “stopping drawing the second tube when a length of the second tube is inserted into the first tube” may be performed. In some embodiments, stopping is responsive to determining, with encoders of the second set of motorized rollers, the length of the second tube is inserted into the first tube.

[0102] At block 708, “cutting the first tube and the second tube” may be performed. In some embodiments, the first tube is cut with a first blade and the second tube is cut with a second blade. In other embodiments, a blade movable between two locations may be used to cut the first and second tubes. In some embodiments, other cutting implements may be used (e.g., lasers, ultrasound, thermal cutters).

[0103] At block 710, “ejecting a cut portion of the first tube and the second tube from the tube cutting apparatus” may be performed. In some embodiments, the cut portion may be ejected by actuating a piston. In some embodiments, the cut portion may be accepted in a collection container.

[0104] At block 712, “inserting the cut portion of the first tube and the second tube at least partially into a chamber of a fluid impermeable barrier of the fluid collection device” may be performed. For example, the cut portion of the first and second tubes may inserted into chamber 104 of fluid collection device 100.

[0105] Returning to FIG. 3, the fluid permeable body 120 is shown including the fluid permeable membrane 340 completely surrounding a perimeter of the support 342. However, in some applications, the fluid permeable membrane 340 may not provide a significant contribution to the wicking performance of the fluid permeable body 120. Rather, the fluid permeable membrane 340 may be provided primarily to increase comfort to a wearer (e.g., provide a less abrasive, smoother surface against the wearer's skin). According, the fluid permeable membrane 340 may not need to completely surround the support 342. Rather, only a portion of the fluid permeable body 120 in contact with a wearer's skin.

[0106] FIG. 8A illustrates a process for manufacturing a fluid permeable body according to at least one embodiment of the disclosure. A reel 802 may include a tubing 842 that may be used to implement a support of a fluid permeable body of a fluid collection device (e.g., fluid permeable body 120 of fluid collection device 100). In some embodiments, the tubing 842 may include an open cell foam. A reel 804 may include a strip of material 840 that may be used to implement a fluid permeable membrane. In some embodiments, the strip of material 840 may include a non-woven material and/or a compression bandage.

[0107] The reels 802 and 804 may rotate as indicated by arrows 810 and 812, respectively, as the tubing 842 and the strip of material 840 are drawn off the reels 802 and 804, respectively, in a direction indicated by arrows 814. In some embodiments, the tubing 842 and material 840 may be drawn by motorized rollers (not shown) similar to motorized rollers 406, 408, 606, and/or 612. The reels 802 and 804 may be arranged such that as the tubing 842 and strip of material 840 are drawn, the strip of material 840 is positioned upon a portion of an outer perimeter 806 of the tubing 842 (indicated in FIG. 8B). When the strip of material 840 is positioned on the tubing 842, the strip of material 840 may be coupled (e.g., secured) to the tubing 842 to form a tube of fluid permeable body 820. In the embodiment shown in FIG. 8A, the strip of material 840 is coupled to the tubing 842 by stitches 808. However, additional or other coupling methods may be used such as applying an adhesive between the tubing 842 and the strip of material 840, and/or melting a portion of the tubing 842 and/or strip of material 840 such that the two are bonded together. Once the tube of fluid permeable body 820 has been formed, the tube may be cut to a desired length (not shown). For example, the tube of fluid permeable body 820 may be drawn into a tube cutting apparatus, such as tube cutting apparatus 400 and/or tube cutting apparatus 600.

[0108] FIG. 8B is a cross-sectional view of the tube of fluid permeable body 820 along the line 8-8 in FIG. 8A. The strip of material 840 only covers a portion of the perimeter 806 of the tubing 842. In the embodiment shown, the strip of material 840 covers approximately one third of the perimeter 806. However, in other embodiments, the strip of material may cover a larger or smaller portion of the perimeter 806. The portion of the perimeter 806 covered may be based, at least in part, on a size of an opening of a fluid impermeable barrier of the fluid collection device (e.g., opening 106 of fluid impermeable barrier 102). The portion of the perimeter 806 of the tubing 842 covered by the strip of material 840 may be selected such that the entire portion of the fluid permeable body 820 exposed by the opening of the fluid impermeable barrier is covered by the strip of material 840.

[0109] FIG. 9 is a flow chart of a method according to at least one embodiment of the disclosure. In some embodiments, the method 900 may be used to couple a tube to a strip of material, such as tube 842 and strip of material 840.

[0110] At block 902 “drawing a tube from a first reel” may be performed. For example, tube 842 may be drawn from reel 802 in some embodiments. In some embodiments, the tube is drawn from the first reel by a set of motorized rollers.

[0111] At block 904 “drawing a strip of material from a second reel” may be performed. For example, strip of material 840 may be drawn from reel 804 in some embodiments. In some embodiments, the strip of material may be drawn from the second reel by a set of motorized rollers. In some embodiments, the set of motorized rollers may be the same set of motorized rollers to draw the tube from the first reel. In some embodiments, blocks 902 and 904 may be performed simultaneously or near simultaneously. In some embodiments, block 902 may be initiated first and continue when block 904 is initiated.

[0112] At block 906 “positioning the strip of material on a portion of a perimeter of the tube” may be performed. In some embodiments, the positioning may be achieved by the arrangement of the first and second reels. In other embodiments, additional reels, motorized rollers, slots, etc. may be used as guides to position the strip of material and/or tubing.

[0113] At block 908 “coupling the strip of material to the tube to form a fluid permeable body” may be performed. In some embodiments, coupling may be achieved by stitching the strip of material to the tube. In some embodiments, coupling may be achieved by applying an adhesive between the tube and the strip of material. In some embodiments, both stitching and adhesive may be used.

[0114] At block 910, “cutting the tube of fluid permeable body to a desired length” may be performed.

[0115] At block 912, “inserting at least a portion of the fluid permeable body into a chamber of a fluid impermeable barrier” may be performed. For example, the fluid permeable body may be inserted into a chamber of fluid impermeable barrier 102 of fluid collection device 100.

[0116] FIG. 10A is a view of a fluid collection device according to at least one embodiment of the disclosure. The fluid collection device 1000 may include a fluid impermeable barrier 1002, a fluid permeable body 1020, and a conduit 1008. In some embodiments, the fluid impermeable barrier 1002 may be substantially the same as fluid impermeable barrier 102 and the conduit 1008 may be substantially the same as conduit 108.

[0117] The fluid permeable body 1020 may include a support 1042, which may be substantially the same as support 342. The fluid permeable body 1020 may also include a fluid permeable membrane 1040. Similar to the embodiment shown in FIGS. 8A-B, the fluid permeable membrane 1040 may only cover a portion of the support 1042. However, instead of coupling the fluid permeable membrane 1040 to the support 1042, the fluid permeable membrane 1040 may be coupled to the fluid impermeable barrier 1002 along a perimeter 1044 proximate to an opening 1006 of a chamber 1004 within the fluid impermeable barrier 1002 (Indicated in FIG. 10B). In the embodiment shown in FIG. 10A, the fluid permeable membrane 1040 is stitched to the fluid impermeable barrier 1002. However, in other embodiments, the fluid permeable membrane 1040 may be glued, thermally coupled, and/or ultrasonically welded to the fluid impermeable barrier 1002 instead of or in addition to stitching.

[0118] FIG. 10B is a cross-sectional view of the fluid collection device along line A-A shown in FIG. 10A. In the embodiment shown, the fluid permeable membrane 1040 extends beyond and edge 1029 of the opening 106 to be coupled at the perimeter 1044. However, in other embodiments, the fluid permeable membrane 1040 may only extend to and be coupled at the edge 1029.

[0119] The embodiments shown in FIGS. 9-10 may use less materials and/or simplify manufacturing since the support is only partially covered by the fluid permeable membrane.

[0120] FIG. 11 is a view of a fluid collection device according to at least one embodiment of the disclosure. The fluid collection device 1100 may include a fluid impermeable barrier 1102, a fluid permeable body 1120, and a conduit 1108. In some embodiments, the fluid impermeable barrier 1102 may be substantially the same as fluid impermeable barrier 102 and the conduit 1108 may be substantially the same as conduit 108.

[0121] The fluid permeable body 1120 may include a support 1142, which may be similar to the same as support 342. However, in some embodiments, the support 1142 may include an open cell polyethylene (PE) foam. In some embodiments, the open cell PE foam may be formed by extrusion. The open cell PE foam may be soft and/or smooth enough at a surface such that a fluid permeable membrane is not necessary to provide comfort to a wearer. Accordingly, in some embodiments, the fluid permeable body 1120 may not include a fluid permeable membrane. Thus, the embodiment shown in FIG. 11, may further reduce materials and manufacturing steps as no fluid permeable membrane needs to be coupled to the support and/or fluid impermeable barrier of the fluid collection device.

[0122] FIG. 12 is a view of a fluid collection device according to at least one embodiment of the disclosure. The fluid collection device 1200 may include a fluid impermeable barrier 1202, a fluid permeable body 1220, and a conduit 1208. In some embodiments, the fluid impermeable barrier 1202 may be substantially the same as fluid impermeable barrier 102 and the conduit 1208 may be substantially the same as conduit 108.

[0123] In some embodiments, the fluid permeable body 1220 may include a support 1242 which may be configured to wick fluid away from an opening 1206 of the fluid impermeable barrier 1202, similar to support 342. However, instead of defining a bore 202 like support 342, the support 1242 may define a channel 1244 extending from an outer surface 1209 of the fluid permeable body 1220 toward an interior 1211 of the fluid permeable body 1220 along a long axis of the fluid permeable body 1220. The channel 1240 may be configured to at least partially enclose the conduit 1208. Thus, instead of passing through a central portion of the fluid permeable body 1220, for example as shown in the embodiments of FIGS. 1-3, the conduit 1208 may extend through the channel 1244 along an inner surface 1203 of the fluid impermeable barrier 1202 opposite the opening 1206. In some embodiments, the conduit 1208 may be adhered (e.g., adhesive, sonic welding, or a combination thereof) to the inner surface 1203 of the fluid impermeable barrier 1202 to keep it in place. In some embodiments, such as the one shown in FIGS. 13B-D, the fluid impermeable barrier 1202 may include a channel into which the conduit 1208 may be friction or snap-fit to hold the conduit 1208 in place.

[0124] The fluid collection device 1200 may be assembled by pressing the fluid permeable body 1220 through the opening 1206 into the chamber 1204 of the fluid impermeable barrier 1202 as indicated by arrow 1245. This may eliminate having to insert the conduit 1208 through a bore of the fluid permeable body 1220. In some embodiments, the fluid permeable body 1220 may extend a length greater than a length of the opening 1206 and/or extend a width greater than a width of the opening 1206. In some embodiments, the fluid impermeable barrier 1202 may include a flexible and/or deformable material that permits the opening 1206 to temporarily widen and/or lengthen in order to accept the fluid permeable body 1220 at least partially into the chamber 1204.

[0125] In some embodiments, the support 1242 may include an extruded open cell PE foam. In embodiments where the support 1242 may include a suitably comfortable material, the fluid permeable body 1220 may not include a fluid permeable membrane. In other embodiments, a fluid permeable membrane may be coupled to at least a portion of the outer surface of the support 1242, for example, as shown in FIGS. 8A-8B. In some embodiments, the fluid permeable membrane may cover a portion of the support 1242 and coupled to the fluid impermeable barrier 1202, for example as shown in FIGS. 10A-10B.

[0126] FIG. 13A is a view of a fluid collection device according to at least one embodiment of the disclosure. The fluid collection device 1300 may include a fluid impermeable barrier 1302, a fluid permeable body 1320, and, in some embodiments, a tube-like extension 1346. The tube-like extension 1346 may extend from a first end 1325 of the fluid impermeable barrier 1302 and define an aperture 1324 at an end thereof. In some embodiments, a conduit (not shown in FIG. 13A) may be inserted and/or coupled to the tube-like extension 1346.

[0127] FIG. 13B is a cross-sectional view of the fluid collection device along the line A-A in FIG. 13A according to at least one embodiment of the disclosure. In some embodiments, the fluid impermeable barrier 1302 may be similar to fluid impermeable barrier 102. However, in addition to defining an opening 1306 and a chamber 1304, the fluid impermeable barrier 1302 may further define a channel 1344 extending from the aperture 1324 (indicated in FIG. 13A) along at least a portion of a length of the fluid collection device 1300. In some embodiments, as shown in FIG. 13B, the channel 1344 may be disposed opposite the opening 1306. However, in other embodiments, the channel 1344 may be located elsewhere, for example, along a side of the chamber 1304 closer to the opening 1306. The fluid permeable body 1320 may be at least partially disposed in the chamber 1304 and cover at least a portion of the channel 1344. In some embodiments, the fluid permeable body 1320 may be substantially the same as fluid permeable body 120, 820, and/or 1020, except that no bore hole may be defined.

[0128] In some embodiments, the channel 1344 may replace at least a portion of the conduit typically inserted into the fluid impermeable barrier 1302 (e.g., conduit 108). The channel 1344 may collect fluid from the chamber 1304 and the fluid may flow through the channel 1344 to the aperture 1324 where it may be removed from the fluid collection device 1300. In some embodiments, the aperture 1324 may be coupled to a vacuum source and/or a tube coupled to the aperture may be coupled to a vacuum source and the channel 1344 may introduce suction into the chamber 1304 to facilitate removal of fluids from the chamber 1304.

[0129] FIG. 13C is a cross-sectional view of the fluid collection device along the line A-A in FIG. 13A according to at least one embodiment of the disclosure. In some embodiments, a conduit 1308 may be inserted through the aperture 1324 into the channel 1344. The channel 1344 may enclose at least a portion of the diameter of the conduit 1308. The conduit 1308 may or may not extend an entire length of the channel 1344. Other than the placement of the conduit 1308 in the channel 1344 rather than through a bore hole of the fluid permeable body 1320, the conduit 1308 may be substantially similar to the conduit 108 in some embodiments. The conduit 1308 may be retained in the channel 1344 by the fluid permeable body 1320 in some embodiments. In some embodiments, an adhesive, other bonding method (e.g., thermal), or a combination of bonding methods may be used to retain the conduit 1308 in the channel 1344. In some embodiments, the channel 1344 may be sized to provide a pressure, friction, and/or snap fit to retain the conduit 1308. In some embodiments, the conduit 1308 may extend beyond the aperture 1324. In some embodiments, the conduit 1308 may be coupled to another tube outside the aperture 1324. In some embodiments, conduit 1308 may not extend beyond the aperture 1324 and the conduit 1308 may be coupled to another tube inside the tube-like extension 1346. In some embodiments, another tube may be coupled to the tube-like extension 1346 rather than directly coupled to the conduit 1308.

[0130] FIG. 13D is a cross-sectional view of the fluid collection device along the line A-A in FIG. 13A according to at least one embodiment of the disclosure. In some embodiments, the conduit 1308 may not be a fully enclosed tube (e.g., a cylinder) but rather an arch. In these embodiments, the channel 1344 may enclose at least a portion of the sides of the arch of the conduit 1308. The channel 1344 may provide the “missing” portion of the tube in these embodiments. Similar to the embodiment shown in FIG. 13C, the conduit 1308 may be retained in the channel 1344 by the fluid permeable body 1320 in some embodiments. In some embodiments, an adhesive, other bonding method (e.g., thermal), or combination of bonding methods may be used to retain the conduit 1308 in the channel 1344. In some embodiments, the channel 1344 may be sized to provide a pressure, friction, and/or snap fit to retain the conduit 1308. In some embodiments, conduit 1308 may not extend beyond the aperture 1324 and the conduit 1308 may be coupled to another tube inside the tube-like extension 1346. In some embodiments, another tube may be coupled to the tube-like extension 1346 rather than directly coupled to the conduit 1308.

[0131] Similar to the embodiment shown in FIG. 12, the embodiments shown in FIGS. 13A-D may eliminate requiring a conduit to be inserted through the fluid permeable body. In some applications, this may reduce assembly and/or manufacturing complexity.

[0132] FIG. 14A is a cross-sectional view of a fluid collection device along a long axis of the fluid collection device according to at least one embodiment of the disclosure. The fluid collection device 1400 may include a fluid impermeable barrier 1402, a fluid permeable body 1420, and a conduit 1408. In some embodiments, the fluid impermeable barrier 1402 may be substantially the same as fluid impermeable barrier 102 and the conduit 1408 may be substantially the same as conduit 108.

[0133] In some embodiments, the fluid permeable body 1220 may include a fluid permeable membrane 1440 at least partially surrounding a support 1442. In some embodiments, the fluid permeable membrane 1440 may be substantially the same as fluid permeable membrane 340. The support 1442 may include a central tube 1448 that extends through the fluid permeable body 1420. The central tube 1448 may define a first outlet 1452 that is open to a reservoir 1422 of the fluid impermeable barrier 1402 and a second outlet 1454 proximate to an aperture 1424 defined by the fluid impermeable barrier 1402. In some embodiments, the central tube 1448 may be coupled to the conduit 1408, which may pass through the aperture 1424 as shown. The central tube 1448 may fluidly couple the conduit 1408 to the reservoir 1422. In some embodiments, such as the one shown in FIG. 14A, the conduit 1408 does not extend into the central tube 1448. In some embodiments, the conduit 1408 may extend a distance into the central tube 1448 to facilitate coupling.

[0134] FIG. 14B is a cross-sectional view of the fluid collection device along the line A-A in FIG. 14A. The support 1442 may further include multiple fins 1444 extending outward from a perimeter 1446 of the central tube 1448 to the fluid permeable membrane 1440. In some embodiments, the fins 1444 may have a length substantially equal to a length of the fluid permeable body 1420. In some embodiments, the fins 1444 may be equally spaced about the perimeter of the central tube 1448. In some embodiments, the spaces 1450 between the fins 1444 may be empty. In other embodiments, the spaces 1450 may be filled with a wicking material (e.g., open cell foam). In some embodiments, the central tube 1448 and fins 1444 may be formed of a single extruded component. The central tube 1448 and fins 1444 may include a fluid and/or air impermeable material in some embodiments. In some embodiments, the central tube 1448 and fins 1444 may include silicone, polypropylene, polyethylene, polyethylene terephthalate, a polycarbonate, a thermoplastic elastomer, etc.

[0135] Similar to the embodiment shown in FIGS. 12-13, the embodiments shown in FIGS. 14A-B may eliminate requiring a conduit to be inserted through the fluid permeable body. In some applications, this may reduce assembly and/or manufacturing complexity.

[0136] FIG. 15A is a cross-sectional view of a fluid collection device along a long axis of the fluid collection device according to at least one embodiment of the disclosure. The fluid collection device 1500 may include a fluid impermeable barrier 1502, a fluid permeable body 1520, and a conduit 1508. In some embodiments, the fluid impermeable barrier 1502 may be substantially the same as fluid impermeable barrier 102. In some embodiments, the fluid permeable body 1520 may be substantially the same as fluid permeable body 120. In some embodiments, the conduit 1508 may be substantially the same as conduit 108 except that the conduit 1508 only extends a length of the fluid permeable body 1520.

[0137] In some embodiments, a hydraulic connector 1560 may be used to couple the conduit 1508 to another tube (e.g., a tube coupled to an external reservoir and/or vacuum source), not shown. The hydraulic connector 1560 may be partially inserted into the fluid impermeable barrier 1502 through an aperture 1524 and into the conduit 1508 as indicated by arrow 1555. In some embodiments, the hydraulic connector 1560 may include barbs 1562 located proximate an end inserted through the aperture 1524. The barbs 1562 may help ensure the hydraulic connector 1560 is retained within the conduit 1508 and/or fluid impermeable barrier 1502.

[0138] FIG. 15B is a cross-sectional view of the fluid collection device of FIG. 15A showing the hydraulic connector inserted according to an embodiment of the disclosure. In some embodiments, in addition to barbs 1562, an adhesive, sealant, sonic welding, and/or other bonding technique may be used to retain the hydraulic connector 1560 in the fluid collection device 1500. The portion of the hydraulic connector 1560 extending from the fluid collection device 1500 may be coupled to another tube (not shown). Optionally, in some embodiments, the fluid impermeable barrier 1502 may include an annular rim 1564 extending from an inner surface 1503 between the fluid permeable body 1520 and a reservoir 1522. The annular rim 1564 may act as a stop to prevent the fluid permeable body 1520 from being displaced when the hydraulic connector 1560 is inserted.

[0139] In some embodiments, the fluid collection device 1500 may be assembled and provided to a wearer and/or other user (e.g., nurse, homecare assistant) with the hydraulic connector 1560 inserted through the aperture 1524. In other embodiments, the fluid collection device 1500 may be provided in a kit that includes the hydraulic connector 1560 and the wearer and/or other user may insert the hydraulic connector 1560 prior to use. In some embodiments, multiple hydraulic connectors 1560 may be provided in the kit. For example, hydraulic connectors 1560 of different sizes may be provided. The wearer and/or other user may select the appropriate hydraulic connector 1560 based on a tube size to be coupled to the hydraulic connector 1560.

[0140] In some embodiments, the hydraulic connector 1560 may allow the conduit 1508 to be made of a different material than a tube coupled to the other end of the hydraulic connector 1560. For example, in some embodiments, the conduit 1508 may include a material that is more flexible than a tube coupled to the hydraulic connector 1560. In some embodiments, the conduit 1508 may be omitted. For example, when the fluid permeable body 1420 is used to implement the fluid permeable body 1520, the hydraulic connector 1560 may be inserted into the central tube of the fluid permeable body rather than the conduit.

[0141] FIG. 16A is an exploded cross-sectional view of a fluid collection device along a long axis according to at least one embodiment of the present disclosure. The fluid collection device 1600 may include a fluid impermeable barrier 1602 and a fluid permeable body 1620. In some embodiments, the fluid permeable body 1620 may be substantially the same as fluid permeable body 120. The fluid impermeable barrier 1602 may include a main body 1670 and an end cap 1672.

[0142] The main body 1670 may include an inner surface 1603 that defines a portion of a chamber 1604 of the fluid impermeable barrier 1602. The main body 1670 may define a portion of an opening 1606 that provides access to the chamber 1604. In some embodiments, such as the one shown, the main body 1670 may further define a tube 1674. The tube 1674 may include an outer portion 1676 that extends from an outer surface of the main body 1670 from a first end 1625 (indicated in FIG. 16B) of the fluid impermeable barrier 1602 and an inner portion 1678 that extends from the inner surface 1603 toward a second end 1627 (indicated in FIG. 16B) of the fluid impermeable barrier 1602. The tube 1674 may define an inlet 1680 at an end of the inner portion 1678 and an outlet 1682 at an end of the outer portion 1676. In some embodiments, the tube 1674 may act as at least a portion of a conduit (e.g., conduit 108) for removing fluids from the chamber 1604. In some embodiments, the tube 1674 may be fluidly coupled to another tube (not shown) at the outer portion 1676. The tube coupled to the outer portion 1676 may remove fluids from the fluid collection device 1600. In some embodiments, the tube coupled to the outer portion 1676 may provide suction (e.g., from a vacuum device) to the chamber 1604. As shown in FIG. 16A, in some embodiments, the main body 1670 may be an integrally formed component. That is, the tube 1674 and inner surface 1603 defining the chamber 1604 may be formed as a single part of the same materials at substantially the same time.

[0143] The end cap 1672 may include an inner surface 1603A that defines another portion of the chamber 1604, for example, a portion of the chamber 1604 including a reservoir 1622 (indicated in FIG. 16B). The end cap 1672 may further define a portion of the opening 1606. The end cap 1672 may include one or more tabs 1684 extending from the inner surface 1603A at the second end 1627 toward the first end 1625. The tabs 1684 may be sized to facilitate positioning of the end cap 1672 and/or tube 1674. For example, the tabs 1684 may prevent the tube 1674 from being pressed against the inner surface 1603A such that the inlet 1680 is fully or partially blocked, which may impede removal of fluid from the fluid collection device 1600. In some embodiments, the tabs 1684 may be arranged such that there is a space 1686 between the tabs 1684. The space 1686 may reduce or eliminate blockage of the inlet 1680 by the tabs 1684. In some embodiments, the tabs 1684 may have opposing curved portions 1688 (indicated in FIG. 16B). The curved portions 1688 may facilitate maintaining a position of the tube 1674 relative to the tabs 1684.

[0144] The main body 1670 and the end cap 1672 may both be injection molded components. In some embodiments, the main body 1670 and the end cap 1672 may include polypropylene and/or other materials suitable for injection molding. Optionally, in some embodiments, the main body 1670 and/or end cap 1672 may be over molded in a thermoplastic elastomer (TPE). In some applications, the TPE may replicate the look and/or feel of silicone, which may be desirable to some users.

[0145] As indicated by arrow 1689, the fluid permeable body 1620 may be inserted at least partially into the main body 1670. The fluid permeable body 1620 may define a bore 1621, through which the tube 1674 may be passed. As indicated by arrow 1691, the end cap 1672 may be placed on a portion of the fluid permeable body 1620.

[0146] FIG. 16B is a cross-sectional view of the assembled fluid collection device of FIG. 16A. In some embodiments, an edge 1690 of the end cap 1672 may be flush with an edge 1692 of the main body 1670. In other embodiments (not shown), the end cap 1672 may extend beyond the edge 1692 of the main body 1670 and partially enclose an outer surface of the main body 1670. In other embodiments (not shown), the end cap 1672 may extend beyond the edge 1692 and the edge 1690 of the end cap 1672 may be enclosed within the main body 1670. The end cap 1672 may be coupled to the main body 1670 by any suitable technique. Examples include, but are not limited to, ultrasonic welding, snap fit, adhesive, pressure fit, and/or friction fit. Once assembled, the opening 1606 and chamber 1604 may be substantially the same shape as the opening 106 and chamber 1604 in some embodiments.

[0147] The embodiment shown in FIGS. 16A-B may reduce or eliminate the need to insert a separate tube into the chamber 1604 of the fluid collection device 1600. The embodiment shown may also reduce or eliminate the need to size the opening 1606 and/or the fluid permeable body 1620 such that the fluid permeable body 1620 may be inserted through the opening 1606.

[0148] FIG. 17 is a flow chart of a method according to at least one embodiment of the disclosure. The method 1700 may be used to manufacture, at least in part, the fluid collection device 1600 in some embodiments.

[0149] At block 1702 “integrally forming a main body of a fluid impermeable barrier by injection molding” may be performed. In some embodiments, the main body defines at least a portion of a chamber of the fluid impermeable barrier, at least a portion of an opening into the chamber and a tube extending from the chamber to an external surface of the fluid impermeable barrier. At block 1704 “forming an end cap of the fluid impermeable barrier by injection molding” may be performed. In some embodiments, the end cap defines at least another portion of the chamber. In some embodiments, blocks 1702 and 1704 may be performed simultaneously or near simultaneously. In some embodiments, block 1704 may be performed before block 1702. In some embodiments, the main body and the end cap may include polypropylene.

[0150] At block 1706 “inserting a fluid permeable body at least partially into the portion of the chamber defined by the main body” may be performed. In some embodiments, the fluid permeable body defines a bore and the tube is inserted into the bore when the fluid permeable body is inserted at least partially into the portion of the chamber defined by the main body.

[0151] At block 1708 “placing the end cap on the fluid permeable body such that the fluid permeable body is at least partially inserted in the portion of the chamber defined by the end cap” may be performed. In some embodiments, blocks 1706 and 1708 may be performed simultaneously or near simultaneously. In some embodiments, block 1708 may be performed before block 1706.

[0152] At block 1710, “coupling the main body to the end cap” may be performed. In some embodiments, coupling may include ultrasonically welding the main body to the end cap. In some embodiments, coupling may include adhering the main body to the end cap with an adhesive. In some embodiments, coupling may include snap fitting, pressure fitting, and/or friction fitting the main body and the end cap together.

[0153] Optionally, in some embodiments, the method 1700 may further include over molding at least one of the main body or the end cap with a thermoplastic elastomer. In some embodiments, this additional step may be performed after block 1702, after block 1704, or before or after block 1710.

[0154] FIG. 18A is an exploded cross-sectional view of a fluid collection device along a long axis according to at least one embodiment of the present disclosure. The fluid collection device 1800 may include a fluid impermeable cap 1870, a second fluid impermeable cap 1872, a conduit 1808, and a body 1820.

[0155] The fluid impermeable cap 1870 may include an inner surface 1803 that defines a chamber 1804 (indicated in FIG. 18B). The fluid impermeable cap 1870 may define an aperture 1824 that extends through the inner surface 1803 to an outer surface at a first end 1825 (indicated in FIG. 18B) of the fluid collection device 1800. The fluid impermeable cap 1872 may include an inner surface 1802A that defines a reservoir 1822 (indicated in FIG. 18B) at a second end 1827 of the fluid collection device 1800. In some embodiments, the fluid impermeable caps 1870 and 1872 may be formed by injection molding. The fluid impermeable caps may include polypropylene and/or other polymers suitable for injection molding.

[0156] The conduit 1808 may be disposed through the aperture 1824. In some embodiments, the conduit 1808 may be substantially the same as conduit 108. In some embodiments, the fluid impermeable cap 1870 may be welded (e.g., sonically welded) and/or otherwise coupled (e.g., adhesive, friction fit) to the conduit 1808. Alternatively, the fluid impermeable cap 1870 and conduit may be integrally formed as a single component by injection molding, similar to the main body 1670 in FIGS. 16A-B.

[0157] FIG. 18C is a cross-sectional view of the body 1820 along line C-C in FIG. 18A. The body 1820 may be substantially cylindrical in shape in some embodiments. The body 1820 may include a fluid impermeable membrane 1890 at least partially surrounding a fluid permeable core 1894. The fluid permeable core 1894 may define a bore 1821, which may extend a length of the body 1820. The fluid permeable core 1894 may be at least partially exposed at an opening 1892 in the fluid impermeable membrane 1890. The opening 1892 may be placed proximate to a wearer's urethra in some applications, similar to the opening 106 of the fluid collection device 100. The fluid permeable core 1894 may wick fluid away from the opening 1892 and toward reservoir 1822. Fluid may be temporarily stored in the reservoir 1822 before being removed from the fluid collection device 1800 via conduit 1808.

[0158] In some embodiments, the body 1820 may be formed by an integral skin polyurethane (PU) foam. Integral skin foam is a flexible foam layered or otherwise surrounded by a denser, typically less flexible foam (e.g., the skin). Both the flexible and less flexible foams may be formed in the same molding process. The skin may be a closed cell foam (e.g., PU foam) that may be used to implement the fluid impermeable membrane 1890 and the inner flexible foam may be an open cell foam (e.g., also a PU foam) that may be used to implement the fluid permeable core 1894. In some embodiments, the opening 1892 may be formed during the molding process for forming the integral skin foam. In other embodiments, the fluid impermeable membrane 1890 may completely surround the fluid permeable core 1894 and a portion of the fluid impermeable membrane 1890 is removed (e.g., cutting, sanding) to create the opening 1892. Although the fluid permeable core 1894 is shown as having a flat surface at the opening 1892 in FIG. 18C, in other embodiments, the surface at the opening 1892 may be curved (e.g., convex).

[0159] In some embodiments, the fluid permeable core 1894 may be formed by an open cell foam (e.g., PU foam, polyethylene extruded foam) and the fluid impermeable membrane 1890 may be a film or a coating applied to the outer surface of the fluid permeable core 1894 (and either not applied at the opening 1892 or later removed to form the opening 1892). The film or coating may be any suitable fluid impermeable polymer, other material, and/or composite. In some embodiments, the fluid permeable core 1894 may be coated with hydrophobic polymers. For example, in some embodiments, the fluid permeable core 1894 may be sprayed with Scotchgard by 3M to provide the fluid impermeable membrane 1890.

[0160] Returning to FIG. 18A, as indicated by arrow 1889, the body 1820 may be inserted at least partially into the fluid impermeable cap 1870. The conduit 1808 may pass at least partially through bore 1821 of the body 1820. As indicated by arrow 1891, the fluid impermeable cap 1872 may be placed on a portion of the body 1820.

[0161] FIG. 18B is a cross-sectional view of the assembled fluid collection device of FIG. 18A. The fluid impermeable caps 1870, 1872 may be coupled to the body 1820 by any suitable technique. Examples include, but are not limited to, ultrasonic welding, snap fit, adhesive, pressure fit, and/or friction fit.

[0162] The embodiment shown in FIGS. 18A-B may reduce or eliminate the materials required for a fluid impermeable barrier compared to fluid impermeable barrier 102 in some applications. In some applications, the embodiment may provide greater flexibility for the length and width of the body as the body does not need to be fit into an opening of the fluid impermeable barrier. In some applications, the embodiment may provide greater flexibility for the size of the “opening” that provides access to the fluid permeable materials for wicking fluid. For example, more of the fluid impermeable membrane 1890 may be removed (or not applied in the first place) to provide a larger area of the opening 1892.

[0163] FIG. 19 is a flow chart of a method according to at least one embodiment of the disclosure. The method 1900 may be used to manufacture, at least in part, the fluid collection device 1800 in some embodiments.

[0164] At block 1902 “forming a first fluid impermeable cap by injection molding, wherein the first fluid impermeable cap defines at least a portion of a chamber and an aperture therethrough” may be performed. At block 1904 “forming a second fluid impermeable cap by injection molding, wherein the second fluid impermeable cap defines at least a portion of a reservoir” may be performed. In some embodiments, blocks 1902 and 1904 may be performed simultaneously or near simultaneously. In some embodiments, block 1904 may be performed before block 1902.

[0165] At block 1906 “inserting a conduit through the aperture of the first fluid impermeable cap” may be performed. Optionally, in some embodiments, method 1900 may further include coupling the conduit to the first fluid impermeable cap. In some embodiments, coupling may include ultrasonic welding and/or applying an adhesive. In some embodiments, block 1906 may be performed before block 1904. In some embodiments, block 1906 may be performed simultaneously or near simultaneously with block 1904.

[0166] At block 1908 “inserting a first end of a body at least partially into the portion of the chamber defined by the first fluid impermeable cap” may be performed. At block 1910 “inserting a second end of the body at least partially into the portion of the reservoir defined by the second fluid impermeable cap” may be performed. In some embodiments, the body defines a bore and the conduit is inserted through the bore. In some embodiments, blocks 1908 and 1910 may be performed simultaneously or near simultaneously.
