One-piece ostomy appliance with pouch and faceplate integrating convex pressure ring

Abstract From the Canadian patent

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.
