  • Patent number: 4846819
    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.

  • Patent number: 4781713
    Abstract: A disposable incontinence pad to be worn by a female. The pad is an essentially two part design including a moisture multi-layered absorbent pad encase in a moisture resistant hydrophobic layer which prevents leakage of urine to the skin of the wearer. The pad has an essentially ovoid opening on the side facing the wearer. Securely attached to the opening into the pad is an essentially ovoid, resilient contoured rim portion which surrounds and conforms itself to the vulvar region of the wearer. The rim portion is contoured so as to direct urine flow into the absorbent pad with minimal splash-back while at the same time preventing urine from contacting the user.
