Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
An external catheter assembly, comprising: an elastomeric membrane of substantially rectangular plan form, including a frustoconical projection extending therefrom characterized by a tapered thickness reducing towards an opening therein; a first annular adhesive strip attachable to said membrane in surrounding relationship about said projection; a cylindrical elastomeric sleeve characterized by an expanded opening at one end thereof, said expanded opening being of a peripheral dimension lesser than the peripheral dimension of said first annular strip, selectively adhered by said expanded opening to said first annular strip; a second annular adhesive strip selectively adhered to said sleeve, said first annular strip and said membrane; and fluid conveying means connected to the other end of said sleeve.
Claim 2
Dependent Claim
