ABSTRACT:
A urinal or incontinence apparatus is disclosed which employs elastic tubular membranes that are opened and closed by collars mounted for coaxial relative rotation. In one embodiment a pair of the membranes are mounted so that when the collars are turned in one rotational sense, one of the membranes is twisted to constrict towards a closed position forming a seal about the penis while the other membrane is twisted so as to expand toward an open position. At the neutral position, elastic counterforces created in the membranes are in balance so that the membranes are held in their partially open positions for insertion or removal. When the collar is moved beyond the neutral position the elastic force in one membrane overbalances that of the other membrane, which is thereby maintained in its sealed position. When removed, the membranes operate by snap action so that one is maintained in its fully closed position preventing leakage from a urine collection bag. In another embodiment a single flexible membrane is attached at its ends to a pair of collars which are threadably mounted together. As the collars are screwed together, the membrane constricts until it reaches its closed position when rotation of the collars is stopped by the threads.
