ONE-PIECE OSTOMY APPLIANCE WITH POUCH AND FACEPLATE INTEGRATING CONVEX PRESSURE RING

摘要

An ostomy appliance is provided in which a relatively stiff but still flexible thermoplastic convex pressure ring is utilized to bond a pouch and faceplate together to provide an integrated one-piece appliance. The pressure ring is directly bonded on its convex side to an adhesive faceplate and is also directly and permanently secured on its opposite side to a collection pouch. Only two annular attachment zones, either in the form of heat seals or adhesive seals, are required to secure the pouch, pressure ring and faceplate together. In a preferred embodiment, the pressure ring additionally functions as a belt-attachment ring.
