ABSTRACT:
Improved valves for use within medical devices include a valve body having a plurality of fluid-passing openings, a resilient liner having raised portions defining flow paths, and a plug having a configuration generally complementary to that of the liner, at least a portion of the plug generally overlying the liner for maintaining raised portions of the liner in sealing engagement with the valve body in a manner that enhances valve integrity as to leakage while simultaneously improving valve operation by providing easy rotation of the plug and liner with respect to the valve body. The in-use illustrated embodiment of the valve is on a urine drainage device, the valve being interposed between a relatively rigid urine flow monitoring and measuring chamber and a flexible collection receptacle, the valve permitting flow path selections for retaining urine within the measuring chamber or for flowing urine therefrom into the flexible collection receptacle or through a sampling port.
