Patent ID: 6913244

Claim:
A urinary valve for controlling fluid flow through a urinary catheter flow passage comprising: a tubular valve body comprising an interior surface and an exterior surface, said valve body defining a central longitudinal axis and first and second valve ends; a tip portion supported on said valve body and located at said second valve end; a cap member comprising an inner surface and an outer surface and positioned over said second valve end for movement in a longitudinal direction parallel to said longitudinal axis; said cap member including an open end and a closed end, said closed end comprising an end wall defining an outwardly facing exterior surface and having an aperture for receiving said tip portion, said aperture comprising a diameter smaller than the diameter of said tip portion; a flange extending radially outwardly from said outer surface of said valve body adjacent said open end of said cap member; said exterior surface of said valve body being tapered adjacent said first valve end, on a side of said flange opposite said cap member, and defining an increasing exterior diameter in a direction from said first valve end toward said second valve end; and wherein said cap member is movable in a first direction toward said first valve end to position said cap member in a closed position with said tip portion extending through said aperture, and forming an exposed wipable surface at an interference seal around the circumference of said tip portion at the exterior surface of the cap member, to prevent fluid flow of liquid and air past said interference seal, and said cap member is movable in a second direction away from said first valve end to position said cap member in an open position with said aperture displaced from said tip member to permit fluid flow through said valve body.
