Abstract
An adhesive faceplate for detachable connection to an ostomy pouch is disclosed. The faceplate has an integrated convex pressure ring for promoting stomal protrusion and a so-called floating flange (i.e., coupling ring) for mechanical attachment to the mating coupling ring of an ostomy pouch. The convex pressure ring is provided with a deep annular recess behind the faceplate's coupling ring to accommodate a user's fingers during a coupling operation, thereby facilitating attachment of a pouch. The pressure ring also includes a thin, inwardly-extending connecting portion which is heat sealed to the backing layer of the faceplate's adhesive wafer and, when that backing layer is formed of a porous material, such heat seal effectively closes the pores of the backing layer in the area of the seal.
