Patent ID: 7604622

Claim:
An ostomy appliance adapted to be removably attached to an ostomy patient for receiving discharge from a stoma and comprising: an inner pouch having a first aperture for receiving said stoma; said inner pouch being defined by a flexible body side or proximal inner pouch wall and a flexible distal inner pouch wall, and one or more peripherally extending inner pouch sealing seams; an outer pouch enclosing said inner pouch, said outer pouch having a second aperture for receiving said stoma and being aligned with said first aperture; said outer pouch being defined by a flexible body side or proximal outer pouch wall and a flexible distal outer pouch wall, and one or more peripherally extending outer pouch sealing seams; said one or more outer pouch sealing seams being manually peelable such that the attachment forces provided by said one or more peelable outer pouch sealing seams may be manually eliminated by manually pulling said distal outer pouch wall in a direction transverse to said one or more peelable outer pouch sealing seams; an adhesive face plate for securing said inner and outer pouches to the skin of said ostomy patient, said face plate comprising: a flexible plate with a body side or proximal surface and a distal surface and comprising a layer of a skin friendly adhesive material and a stoma receiving aperture for receiving said stoma; and a generally annular face plate coupling ring having an inner and an outer periphery and attached to said face plate and adapted for releasably engaging a corresponding generally annular pouch coupling ring attached to said inner and outer pouches, the face plate coupling ring being secured to said flexible plate with the plane of said face plate coupling ring generally parallel to the plane of said flexible plate and generally concentric with said aperture for receiving said stoma; one or more filters in said face plate for deodorizing flatus gas; and one or more flatus gas passages extending from the area located within said inner periphery and through said one or more filters.
