A convex pressure ring assembly, and its combination with an ostomy appliance, for exerting peristomal pressure to cause protrusion of a stoma into the openings of a faceplate and pouch and thereby promote more effective operation of the collection appliance. The pressure ring assembly is applied to the proximal (patient-facing) surface of the faceplate and includes a distal support ring of convex configuration formed of relatively rigid plastic, an intermediate ring of resilient, thermoformable material, and a proximal ring of soft, deformable, moisture-absorbing skin barrier material having both dry and wet tack.

An ostomy appliance comprising a collection pouch formed of plastic film having a wall provided with a stoma opening; a flexible and generally planar faceplate having proximal and distal surfaces and having an opening therethrough aligned with said stoma opening of said pouch; adhesive means along said proximal surface for adhesively securing said faceplate to peristomal skin surfaces of a wearer; connecting means connecting said distal surface of said faceplate to said wall of said pouch about said stoma opening; wherein the improvement comprises a pressure ring assembly including a relatively rigid support ring having an annular wall with inner and outer wall portions; said inner wall portion having a central opening aligned with said openings of said faceplate and pouch and having a convex proximally-directed curvature; means securing the outer wall portion of said support ring to the proximal surface of said faceplate about said faceplate opening; an intermediate ring of resilient, moisture-impermeable, thermoformable material secured to and extending over the convex proximal surface of said support ring; and a barrier ring composed of soft, formable, moisture-absorbing skin barrier material of dry and wet tack secured to and covering the proximal surface of said intermediate ring.
