1. A device for attaching a stoma to a pouch, where said stoma is surrounded by peristomal skin, said device comprising:
- a barrier ring having a posterior side intended for attachment to the peristomal skin and an anterior side facing away from the peristomal skina ring seal disposed over the anterior side of the barrier ring, said ring seal having a stoma opening intended for placement over the stoma and axially aligned with the stoma;
a blotter ring disposed between the barrier ring and the ring seal, said blotter ring comprised of a porous material capable of absorbing stoma discharge; and
a support washer disposed over the blotter ring and the ring seal, where the ring seal and blotter ring are fixed around their respective circumferences to the support washer.
