Background of the Invention
The present invention is directed to a vaginal irrigation syringe for use in connection with feminine hygiene.
Numerous devices have been designed for this purpose over the years, of which the following are typical.
U.S. Pat. No. 2,888,925 illustrates a typical structure in which a nozzle member is extended through a hollow ceramic body which is adapted to form the proximal end of the structure for sealing engagement with the vaginal orifice, and is provided with openings for the passage of liquid discharged from the nozzle into the hollow body, from which it may be discharged to the exterior, U.S. Pat. No. 1,481,989 illustrates a somewhat similar structure provided with additional means for extending and retracting the tubular nozzle member with respect to a body member through which it extends. Again, the sealing member is provided with apertures therein for the flow of liquid, discharged by the nozzle, from the body cavity and to the exterior.
U.S. Pat. No. 826,6855 illustrates a medical irrigator having a bulb structure which is provided with a tapering portion terminating at its small end in an opening in which is coaxially disposed a discharge nozzle for liquid. Liquid discharged from the nozzle is adapted to enter the bulb structure through the annular opening surrounding the discharge opening of the nozzle for exiting from the bulb through a suitable outlet.
U.S. Pat. No. 2,908,273 illustrates a nozzle structure, generally similar to those previously described, in combination with power means for supplying liquid to discharge openings in the nozzle structure and withdrawing liquid through outlet openings therein, with such flows being power-actuated.
Brief Summary of the Invention
The present invention is directed to a relatively simple syringe structure which may be readily constructed from metal, plastic, or the like and comprises an elongated nozzle structure which is provided at its proximal end for connection to a liquid supply and at its distal end with a liquid outlet. The structure is also provided with liquid discharge opening therein which, in a preferred embodiment, may be disposed in an intermediate portion of the body relatively close to the distal end and the fluid, the liquid outlet in such end, with such discharge openings communicating, at the proximal end with the exterior so that liquid is free to flow into the discharge openings and the discharge exteriorly from the structure.
In one embodiment of the invention, the structure is designed as an elongated hollow tubular body member provided with the respective liquid outlet and discharge outlet therein and a cooperable stem member having a hollow tubular stem which operatively connects a fluid inlet in the base portion with the fluid outlet at the distal end of the body member. The discharge outlet in the body member communicates with the interior of the hollow body member and the base portion of the stem member is provided with a discharge passageway therein, which operatively connects the interior of the hollow body member with the exterior. Liquid thus may be supplied to the fluid outlet at the distal end of the structure and fluid discharge through the discharge inlet and eventually discharged through the discharge outlet to the exterior.
In another embodiment of the invention, the structure is made in three pieces comprising a body member, a stem member and a base member which is separate from the stem member. In this construction the stem member is secured to the body member by the base member. Again, the hollow stem member forms a connecting passageway from a fluid inlet in the stem member to the fluid outlet in the distal end of the body member with a return discharge passageway extending to the exterior through corresponding discharge inlets disposed in the body member and channels formed in portion of the stem member which communicate at their proximal end with the exterior at the lower end of the base member.
Either embodiments of the invention may be utilized in conjunction with a hollow bell-shaped sealing member of soft rubber or the like, which may be engaged with the structure at the proximal end thereof to provide a fluid seal bettween the syringe structure and the walls of the vaginal orifice.
It will be noted that in either embodiment the liquid outlet and discharge inlet are so disposed in the body member that, in use, they both will be disposed within the vaginal cavity, while the both the fluid inlet and discharge are disposed exteriorly of the vaginal cavity as well as at the exterior side of any sealing member.
Either of the embodiments of the invention illustrated may be constructed from metal or suitable plastic materials. Likewise, the base member and body member in the first embodiment may be constructed to provide a press fit therebetween, or provided with cooperable treads, and in like manner, in the second embodiment, the base member may be connected to the body member by similar connections. In the event the structure is constructed of plastic, the same corresponding parts may be suitably secured by a press fit or by a suitable cementing or welding of the corresponding parts.

Detailed Description of the Invention
Referring generally to the drawings and more particularly to FIGS. 1-4, the reference numeral 1 indicates generally an elongated body 1, having a fluid inlet 2 at the proximal end thereof and a plurality of fluid outlets 3 at the distal end thereof which are in communication with the fluid inlet 2, whereby fluid may be supplied to the inlet 2 and discharged through the outlets 3. The body is also provided with a plurality of fluid discharged inlets 4, illustrated as being disposed in an intermediate portion of the body adjacent the distal end of the body 1, which are in communication with discharge outlets 5 at the proximal end of the structure.
As hereinafter described in detail, the inlet 2 and outlet 3 are operatively connected by a passageway and the discharge inlet 4 and discharge outlet 5 are connected by a second passageway, which passageways are independent of one another. FIGS. 2-4 illustrate the details of the construction and in particular the respective fluid passageways therein.
The structure of FIG. 1 may be readily fabricated in the form of two independent members which are suitably assembled to form a unitary structure. The first is the body member 6 which, as illustrated in FIGS. 2-4, is formed with a central bore 7 therein with which the discharge inlets 4 communicate, as clearly illustrated in FIG. 2. Cooperable with the body member 6 is a stem member indicated generally by the numeral 8 and comprising a base member 9 and a hollow stem member 10. As illustrated in FIG. 2 the distal end of the body member 6 is provided with a relatively small coaxial bore 11 therein with which the fluid outlet 3 communicates, with the distal end of the stem 10 extending, with a snug-fit, into said bore 11. The base member 9 is also provided with a concentric portion 12 which is seated in a counter bore 13 formed in a proximal end of the body member 6, with such concentric portion being provided with a plurality of generally rectangularly-shaped channels 14 therein which extend in axial direction and communicate at their upper ends with the bore 7. The lower ends of the channels 14 extend below the proximal end of the body member 6 and form the generally radially extending discharge outlets 5, as clearly illustrated in FIG. 4. As illustrated, the base member 8 may be provided at the fluid inlet 2 with a suitable stem portion 15 adapted to receive a supply hose, or supply syringe ball as partially indicated in broken lines in FIG. 5.
The proximal end of the body member 6 is provided with an annular bead or flange 16 which may form a seat or stop for a sealing member 17 indicated in dotted lines, which may be formed of suitable material such as a relatively soft rubber or the like and is secured to the body member by a press-fit. The member 17 may form a fluid tight seal with the vaginal orifice to prevent liquid flow therefrom other than through the discharge outlets 5.
FIGS. 5-8 illustrate a further embodiment of the invention, which is generally similar to that illustrated in FIG. 1 with the exception that the base member 8 is constructed as a separate component. The base member 8 is secured to the body member 6 and forms the means for securing the stem member 8 to the body member.
In this construction, as illustrated in FIG. 6, the distal end of the body member 6 is provided with an axially extending bore 3a as well as a plurality of radially extending bores with the stem member 10 adapted to supply fluid from the inlet 2 to the fluid outlets 3 as in the construction of FIG. 1. As illustrated in FIGS. 7 and 8, the base member 8 is formed as a separate component with respect to the stem member 10, with the latter having enlarged concentric portion 12 which is provided with three longitudinally extending channels 14 therein, which communicate at their upper end with the bore 7 and at their bottom ends form the discharge outlets 5.
As illustrated in FIG. 8, the base member 8 may be threadedly connected with the adjacent end of the body member 6 or by secured thereto means of a press-fit. Also if desired, where the structure is of plastic or similar material, the parts may be cemented together as well as attached by the use of threads or a press-fit.
In use, the structure such as illustrated in FIG. 1, with the sealing member 17 in position and the fluid inlet 2 suitably connected with a supply means or fluid, the structure is inserted in the vaginal channel and the vaginal orifice sealed by engagement of the sealing member 17 therewith.
In use, the body member 6 is inserted in the vaginal channel and the vaginal orifice sealed by engagement of the sealing member 17 therewith. Following the introduction of the fluid through the outlets 3, such fluid may ultimately enter the discharge inlets 4 and be discharged from the vaginal channel through the discharge outlets 5, exteriorly of the structure.
The structure may be readily cleaned following use, and if constructed in the form of separable components, may be disassembled prior to the cleaning operation.
It will be noted that I have provided an extremely simple yet high efficient structure that is very durable in use.
Although I have described my invention by reference to particular illustrative embodiments, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. I therefore intend to include within the patent warranted hereon all such changes and modifications as may reasonably and properly be included within the scope of my contribution to the art.
