Abstract
An external catheter assembly includes a thin elastomeric membrane attachable to the body of a user and provided with a frustoconical projection feathered in wall thickness towards the opening therein. A first, double-backed adhesive strip is attachable to the membrane around the projection to adhesively engage the open end of an elastomeric sleeve and a second adhesive strip conformed to engage the sleeve, the first strip, and the membrane. The other end of the sleeve extends to a flexible collection container which may include a check valve opposing backflow therefrom.
