Abstract

An essentially leak proof urine collection device to be worn by a female which can be easily and comfortably positioned. The device is basically a receptacle, essentially semi-ovoid in shape, having an ovoid-shaped opening defined by a rim portion to which is attached an encapsulated deformable polymer gel ring which, when in use, substantially conforms itself to the contours of the vulvar tissue contacted by the gel, thus forming an essentially leak proof seal.

Claims

1. A urine collection device to be worn by a female comprising a receptacle having a top opening surrounded by a rim defined by integrally formed side and bottom wall surfaces wherein the top opening is sufficiently large to surround the urethral opening of the female without contacting or invading the urethral opening, a deformable gel ring attached to said rim wherein said gel ring consists of an encapsulant layer which substantially encloses a gel layer therein and wherein said gel ring contours itself to mate substantially with the surface contours of the vulvar tissue of the female wearing the device.

2. The device according to claim 1 wherein the receptacle is semi-ovoid in shape and wherein said rim and wall portions define an opening sufficiently large enough to surround and enclose the urethral opening and portions of the vulvar tissue of the female wherein the device has ventrally and dorsally oriented ends when worn by a female in a standing position.

3. The device according to claim 2 wherein the dorsally oriented end of said device is tapered and curves upwardly to conform to the natural arch of the vulvar anatomay between the urethral opening and the anterior surface of the vaginal opening.

4. Device according to claim 2 in which the dorsal end is tapered and curved upwardly to conform to the natural arch of the vulvar anatomy between the urethral opening and the anterior surface of the vaginal opening in such a way that the dorsal end is substantially vaginally non-invasive.

5. The device according to claim 1 wherein the encapsulant layer is a cured silicone elastomer having more flexibility than the rim and wall surfaces of the device and wherein the encapsulant layer entirely encloses the gel layer of the gel ring.

6. The device according to claim 1 wherein the rim and wall surfaces are formed from a high strength, stable cured silicone rubber elastomer having less flexibility than the gel ring of said device.

7. The device according to claim 1 wherein the gel layer is a cured cross-linked silicone gel entirely enclosed by said encapsulant layer.

8. Device according to claim 1 in which the flexible encapsulant is a cured silicone elastomer.

9. The device according to claim 1 further comprising a bottom opening formed in the bottom wall of said receptacle and includes a conduit means communicating therewith.

10. A urine collection device to be worn by a female comprising a receptacle having top and bottom openings wherein said top opening is surrounded by a rim defined by integrally formed side and bottom wall surfaces wherein the top opening is sufficiently large to surround and enclose the urethral opening of the female without contact or invasion of the urethral opening by the device, a deformable gel ring attached to said rim wherein said gel ring consists of a flexible encapsulant layer enclosing an inner gel layer and wherein said gel ring contours itself to mate substantially with the surface contours of the vulvar tissue of the female wearing the device and wherein the device includes ventral and dorsal ends wherein the dorsal end of said device is tapered and curves upwardly to conform substantially to the natural arch of the vulvar anatomy between the urethral orifice and the anterior surface of the vaginal opening.
