Abstract

Abstract A continent ostomy valve comprising a drainage tube which is secured at one end within the stoma of the patient while the other end passes through an orifice in a disk-shaped valve body which includes releasable clamping means for selectively occluding the drainage tube. The outer end of the drainage tube is stored on the face of the valve body under a cover which encloses the valve body and provides a low profile of uniform configuration.
