Description
Field of the Invention
The present invention relates to a device and method for providing liquid to a user's mouth. More specifically, the present invention relates to a device and method for enabling a person to drink liquid from a container after initial positioning of the device.
Background of the Invention
Drinking an adequate amount of liquid is beneficial to human health, especially skin health and skin healing, and diminishes the frequency of urinary tract infections. However, drinking liquids is often problematic for a person with diminished control of his arms or hands, such as a quadriplegic. Such a disabled person, who might be confined to a bed or wheelchair, often is unable to move his arms, let alone to grasp and position objects with his hands. An attendant, therefore, must regularly physically assist the disabled person to enable him to consume an adequate amount of liquid. Typically, the attendant must position a tube adjacent the user's mouth and hold the tube while the disabled person draws the liquid through the tube and drinks. Needing the attendant's assistance to drink restricts the disabled person's independence, uses the attendant's time, and incurs costs. Furthermore, disabled persons are often subject to urinary tract infections and decubitus ulcers that may be caused by inadequate hydration.
There is a need for a drinking device that may be mounted to or near a disabled person's bed or wheelchair and that enables the disabled person independently to access and drink from a source of liquid by making small movements of his head or mouth. There is also a need for a device that enables the user to take a drink therefrom despite significant jolts and bumps that may be applied to the device as the user goes about his daily routine on a wheelchair.
A prior art device that is directed to such a need is the SWIGGLE DRINKING SYSTEM ("SWIGGLE") produced by Edstrom Industries, Inc., Waterford, Wis. The SWIGGLE includes a container, tubing connected to the bottom of the container, and a drinking valve. Resembling a rabbit feeder, the SWIGGLE's liquid flows from the container to the valve by gravity, which unfortunately requires that the container be located higher than the user's mouth. Thus, wheelchairs often must be equipped with additional tall structure to support the SWIGGLE container. Also, spills and leaks, if any, that may drip from the SWIGGLE may strike the user, thus, wasting the liquid and causing discomfort and embarrassment to the user.
The SWIGGLE device may also be equipped with flexible tubing. However, the SWIGGLE's flexible tubing lacks adequate support for keeping the valve in a fixed position adjacent the user's mouth. Whenever the SWIGGLE is jolted, for example when a wheelchair bumps into a wall, the flexible tube is jolted and knocked from its desired position with the result that the user is precluded from taking a drink. This is a substantial disadvantage if the device is placed on a wheelchair or similar apparatus, and therefore subject to significant forces and jolts as the wheelchair is moved about and bumps into furniture and walls.
Another device, the SIP-N-PUFF, supplied by Therafin Corporation, 19747 Wolf Road, Mokena, Ill. 60448, also uses a tube that is positioned adjacent a user's mouth. However, the SIP-N-PUFF does not carry liquid and is not a drinking device. Rather, the SIP-N-PUFF enables control of a wheelchair by using, for example, LOC-LINE segments, described hereinbelow, to convey air pressure from the user's mouth to a pneumatic switch. Specifically, the user inhales and exhales into the tube to actuate the pneumatic switch.
Another device, shown in FIG. 4 ("Prior Art") and FIG. 5, that addressed some of these problems comprised a cylindrical container 116 with a lid 118, a rigid tube 120 immovably fixed to the lid 118, and numerous ball and socket type, LOC-LINE segments 122 that are successively coupled together and coupled to the rigid tube 120. The device also included a flexible tube 124 that extends from a liquid 126 within the container 118 through a continuous passage formed by the rigid tube 120 and the segments 122. The device was able to be attached to a principal apparatus, such as a wheelchair, by a mounting clamp 128 that is attached to the rigid tube. The clamp 128 comprised an elongate bar 130 formed into a loop 132 on one end and having several holes 134 for accepting a U-shaped bracket 136. The clamp 128 was able to affix the device to a principal apparatus by screwing nuts 138 onto threaded ends of the U-shaped bracket 136. The holes 134 in the elongate bar 130 enable a bolt 140 to tighten the loop 132 around a knob 142 located on the rigid tube 120. Unfortunately, the clamp 128 permitted the device to easily shift from its desired position when the principal apparatus was vibrated or bumped. Moreover, because container 116 was supported only by hanging with screw threads from lid 118, container 116 was subject to unintended separation therefrom, especially if vibrated or improperly affixed by an attendant. Such separation caused container 116 to fall from the remainder of the device, and to spill liquid 126. Also, attendants must exercise greater care with this device because of the danger of unintended separation of lid 118 and container 116.
It is an object of the present invention to provide a drinking device that enables the user to draw upon liquid by suction; that may be mounted to a disabled person's bed, wheelchair, or other apparatus, or even a wall; that may be disposed either higher or lower than the user's mouth; that fixes the tubing configuration and outlet point at a variety of adjustable positions; that has a container that is easier for an attendant to securely install and remove; that directly supports the container rather than indirect support through the lid; and that maintains the tubing at a fixed position despite being vigorously vibrated and bumped.
Summary of the Invention
In order to achieve the above and other objects of the invention, a drinking device that enables a user to draw upon liquid by suction is provided. The drinking device comprises a container, a holder and a fastening member, a conduit, and conduit support means. The conduit extends from the container, which holds the liquid, and through the support means. The holder and fastening member couple the container to a principal apparatus, such as a wheelchair, bed, intravenous pole, bicycle, or wall. The support means support the conduit in an infinite variety of adjustable positions. Thus, an outlet of the conduit may be positioned adjacent the user's mouth so as to enable the user to access the outlet with only slight movement of his head or mouth. The holder, fastening member, and support means work together to maintain the conduit outlet position despite significant forces and jolts that may be applied to the device.
A method of providing liquid to the user's mouth is also provided. The method comprises the steps of providing the device that enables the user to draw upon the liquid within the container, fastening the device to the principal apparatus, and rigidly positioning the outlet of the device adjacent the user's mouth.

Description of a Preferred Embodiment
Because the device enables a user to drink without using his hands to grasp the device, the present invention may be employed by persons with disabilities. Thus, an embodiment of the present invention is shown attached to a wheelchair for illustration. However, the present invention is not limited thereto and, accordingly, reference should be made to the appended claims, rather than to the specification herein, as indicating the scope of the invention. Now, referring to the drawings wherein like reference numerals designate corresponding structure throughout the views, and referring particularly to FIG. 1, a drinking device 10 in accordance with the present invention is provided. FIG. 2 shows an exploded view of the drinking device 10 in accordance with the present invention. The drinking device 10 includes a holder 12, a fastening member 14, a container 16, a lid 18, a flexible tube 20, a bulkhead connector 22, and a support assembly 24.
The holder 12 comprises a cylindrical cup that has a platform 38 on which the fastening member 14 attaches. In a preferred embodiment of the present invention, the fastening member 14 includes a circular clamp that is split into a first member 40 and a second member 42. The first clamp member 40 has a flat side that is held to the holder platform 38 by an assembly nut and bolt 44. The second clamp member 42 is attached to the first clamp member 40 around a structural member of a principle apparatus 80 by two clamp nuts and bolts 46. The first clamp member 40 may attach to the holder platform 38 at various orientations so as to enable upright attachment of the drinking device 10 to either horizontal, vertical, or obliquely oriented structural members of the principal apparatus 80.
The holder 12 and fastening member 14 are of the type supplied by Dyer Industries, Inc., Unit 3, 165 Fishermills Road, Cambridge, Ontario, N3E1E1, under Model Number 0505. In alternative embodiments of the present invention, the holder and fastening member may be of a different type, for example, a multiple hook and loop fastener sold under the trademark VELCRO or a system of straps (not shown). Moreover, for illustration, FIG. 2 shows the structural member of the principal apparatus 80 to be a horizontal tube. However, attachment of the drinking device 10 to a structural member that has other shapes and orientations is encompassed by this invention. Specifically, the structural member of the principal apparatus 80 may comprise a rail of a wheelchair, a rail or head board of a bed, a frame of a bicycle, a part of a chair, and an intravenous pole or wall that is positioned near the user, but is not limited thereto.
The container 16 includes a cylindrical wall 28, an outer surface 30, an inner surface 32, a chamber 34, and screw threads 36A near an open top. The chamber 34 holds a liquid 74. The lid 18 includes screw threads 36B that mate to the container screw threads 36A. In a preferred embodiment of the present invention, the container 16 is inserted into a compressible, cylindrical sleeve 26 that is inserted into the holder 12. The outer diameter of the sleeve 26 is larger than the inner diameter of the holder 12 so as to partially compress the sleeve 26. Such compression securely fastens the sleeve 26 and container 16 within the holder 12. The sleeve 26 also thermally insulates the container 16 to diminish heat transfer between the atmosphere and the liquid 74. In an other embodiment of the present invention, the sleeve 26 may be omitted (not shown). In such an alternative embodiment, the container 16 may be held by the holder 12 in a press fit.
A bulkhead connector assembly 22 is connected through an opening 48 in the center of the lid 18. The bulkhead connector assembly 22 includes a male threaded part 50, a female threaded part 52, an exterior gasket 53a, an interior gasket 53b, and an o-ring seal 58. The male part 50 extends through the opening 48 and is screwed into the female part 52. The o-ring 58 is conventionally disposed between the male part 50 and the female part 52. The exterior gasket 53a is held between the male part 50 and an exterior surface of the lid 18. The interior gasket 53b is held between the female part 52 and an interior surface of the lid 18. An end 51 of the male part 50 opposite the threads has a ball shape suitable for mounting to a one-half inch diameter socket, as is described hereinbelow.
In an embodiment of the present invention, the bulkhead connector assembly 22 permits air leakage through the opening 48 so as to enable equalization of pressure between the container interior and the atmosphere. In an alternative embodiment of the present invention, the male part 50 is screwed to a nut, thereby omitting the female threaded part 52 and the o-ring 58. Also, the interior gasket 53b may be eliminated. In yet another embodiment of the present invention, the lid 18 has a connector integrally formed as part of its top that connects directly to the support assembly 24, thereby eliminating the bulkhead connector 22.
The present invention encompasses any support assembly that deformably supports a flexible tube in a variety of configurations. One embodiment of the support assembly will now be described. The support assembly 24 attaches to the ball end 51 of the male part 50 of the bulkhead connector 22. The support assembly 24 includes an adapter 54, several segments 56, and a nozzle 58. The adapter 54 includes a one-quarter inch inside diameter ball end 62 and a one-half inch inside diameter socket end 60 that connects to the ball end 51 of the bulkhead connector 22. A one-quarter inch socket end 64 of a first one of the segments 56 connects to the adapter ball end 62. A one-quarter inch inside diameter ball end 66 of the first one of the segments 56 attaches to the socket end of an adjacent segment. Several segments 56, for example twenty, are sequentially connected to obtain a desired length of the support assembly 24. The overall length of the support assembly 24 will depend upon the specific application, as will be understood by those skilled in the art. The nozzle 56 has a one-quarter inch inside diameter socket end 68 for mating to a ball end of a last one of the segments 56. The nozzle 58, segment 56, adapter 54, and male part 50 are LOC-LINE 1/4" round nozzle (part number 41404), 1/4" segment (part number 41401), 1/4" to 1/4" adapter (part number 51821), and 1/2" N.P.T. connector (part number 51805), respectively, as supplied by Lockwood Products Inc., 5615 SW Willow Lane, Lake Oswego, Oreg. 97035.
A flexible tube 20 extends from the interior bottom of the container 16 and through a continuous passage within the bulkhead connector 22 and support assembly 24. An inlet end 70 of the tube 20 is disposed within the liquid 74. An outlet end 72 of the tube 20 extends beyond the support assembly 24. The tube 20 eliminates potential liquid leakage through the support assembly 24 and enables cleaning and replacing of the wetted surfaces.
In operation, the drinking device 10 is usually disposed on the principal apparatus 80 lower than the user's mouth. FIG. 3 illustrates such a disposition on a wheelchair. The holder 12 securely holds the container 16 by friction created by compressing the sleeve 26 against the container exterior surface 30. The support assembly 24 may be manipulated into an infinite variety of configurations, as shown in phantom in FIG. 3. Upon adjustment by an attendant, the support assembly 24 rigidly fixes the position of the tube outlet 72 adjacent the user's mouth. Thus, by only a small movement of the user's head or mouth, the user may draw by mouth suction upon the fluid 74 that is within the container 16. The combination of the support assembly 24, the fastening member 14, and the interference fit among the container 16, sleeve 26, and holder 12 provides a device that maintains the position of the outlet 72 adjacent the user's mouth despite vibrating and bumping that are common to wheelchairs, bicycles, and similar apparatus.
