Abstract: The disclosed device comprises a cup-shaped receptacle for collecting urine from the orifice of the female user's urethra. Such receptacle has a bottom wall portion and an annular side wall portion projecting upwardly therefrom and terminating in a soft rounded compliant annular lip portion for sealing engagement with the user's external vestibular tissues around such orifice. A drain tube portion connects with the bottom wall portion. The side wall portion is hollow and comprises spaced inner and outer shells merging at thier upper extremities to form such rounded lip portion. The inner and outer shells, including the lip portion, are made of a thin highly flexible compliant silicone elastomer or other similar material.

Abstract: An improved female urinary appliance is disclosed. The appliance includes a mouth surrounding a urine-receiving cavity, and a drainage channel. The mouth is adapted to be positioned within the labia folds of the user, in contact with the vestibular tissue around the meatus and held in place by gentle vacuum. A valve is preferably used in combination with the appliance, and includes an inlet and an outlet, for maintaining a preselected vacuum condition at the valve inlet and a predetermined pressure condition at the valve outlet is disclosed. In preferred use, the drainage channel is suitable connected in spaced relation to the valve inlet. The valve contains a flow control element adapted to control flow of urine from the cavity. While the mouth is held against the vestibular tissue by gentle vacuum, urine flowing through the appliance and valve entrains gas present in the cavity.

Abstract: A backflow check valve is disclosed. The valve comprises a housing, a biasable disk within the housing and a valve seat carried by the housing against which the disk is urgeable. The housing has a fluid inlet and a fluid outlet. The disk is preferably disposed transverse to a preselected direction of fluid flow through the housing for controlling fluid flow therethrough. The disk is urgeable against the seat for preventing fluid from flowing contrary to the preselected direction of flow. The housing includes means in the housing for biasly engaging therein opposite sides of the disk. The housing further includes means in the housing for biasly engaging the disk along a first pair of spaced opposite end portions and for biasly engaging the disk along a second pair of spaced opposite end portions.

Abstract: A flexible resilient valve disc is mounted in a valve body and is biased by its own resilience against an annular valve seat surrounding an inlet cavity in an inlet body member. The valve disc is adapted to be deflected away from the valve seat into an outlet chamber and an outlet body member. Mating pin and socket formations are formed axially on the body member. The valve disc has a central mounting hole which is received with an interference fit on the pin formation. Initially, the disc is flat, but is deflected into a cupped shape by engagement with the valve seat, when the valve members are assembled and bonded together. The inlet and outlet body members have inlet and outlet connections with inlet and outlet passages therein. The inlet and outlet connections are offset in a radially outward direction from the central axis of the valve.

Abstract: An improved bag shut-off clamp is disclosed. The clamp comprises curved resilient first and second legs connected by an integral hinge. The clamp includes means for holding the ends of the first and second legs together for engaging transversely a closable bag having a neck interposable intermediate the first and second legs at the neck thereof for closing the bag at the neck. The clamp includes means for biasly urging opposed surfaces of the first and second legs engaging the neck substantially continuously together along the length thereof. The clamp further includes means for manually engaging the legs in biased relation. The clamp further includes means for localizing pressure along the length of the neck engaged between the legs, thereby sealingly closing the bag at the neck.

Abstract: A one-piece external female urine collection device is disclosed. The device is adapted to be positioned within the labia folds of the user, and to be in contact with the vestibular tissue around the meatus defining the urethral opening. The device includes a generally ovoid and cup-shaped member, and has a generally centrally disposed bore opening so that urine can flow through the member and the device. The upper periphery of the member has a generally convexly curved exterior surface and a substantially continuously curved ridge extending upwardly therefrom defining upper portions of a cavity within the member. The upper periphery and the ridge define a generally adjacent pair of sealing surfaces. The inner surface is generally disposed farther upwardly relative to the outer. The adjacent surfaces permit the device to sealingly and continuously make contact with the female by engaging with the labia folds and the above-mentioned vestibular tissue.

Abstract: Useful for removing kidney stones, gall stones and other objects from human body passages, the extracting device comprises a thin tubular rubber sleeve having its proximal and distal ends connected to the distal ends of outer and inner flexible tubes insertable into the body passage. The sleeve is inflatable by fluid pressure, supplied along the clearance space between the tubes to dilate the passage. The distal end of the sleeve is turned inside out and, when the sleeve is inflated, forms a soft annular flaring convex portion bulging beyond the distal end of the inner tube for sealing engagement with the stone, which is captured by suction, applied through the inner tube. Then, the inner tube is retracted, so that the suction pulls the stone within the sleeve while progressively turning the sleeve inside out around the stone to envelop the stone, for removal with the tubes.
