<p>A valve for a prosthetic device for ileostomates, colostomates and the like has a tubular body (10) which is open at one end (11) thereof. The other end of the body is closed by a generally wedge-shaped extension (12) which terminates in a pair of openable lips (13). The valve is made of a resilient material, such as silicone rubber, and the lips (13) are biased into contact with each other to form a sealed opening for the valve. Preferably the lips comprise a pair of flat flaps of the resilient material. The valve may be included within a drainage tube (21, 31) of a continence device for ileostomates.</p> |
