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 recess is also useful because it may accommodate the flexible web (which is preferably pleated to allow greater movement of the faceplate's coupling ring) when the coupling ring is immediately adjacent the remainder of the faceplate. The pressure ring 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.
