Abstract:
1. An ostomy appliance for receiving discharge from a human stoma and comprising: attachment means for attaching the appliance to the peristomal skin surface of a user of the appliance, and an ostomy pouch assembly comprising an inner pouch attached to said attachment means and having a first aperture for receiving the stoma of said user, 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, attached to said attachment means and 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, said attachment means comprising an adhesive face plate for securing said inner and outer pouches to the skin of an ostomy patient, said faceplate comprising: a flexible plate with a bodyside or proximal surface and a distal surface and comprising a layer of a skin friendly adhesive material and a stoma receiving aperture for receiving a stoma of said patient, and generally annular face plate coupling means having an inner and an outer periphery and attached to said face plate and adapted for fixedly or releasably engaging corresponding generally annular pouch coupling means attached to said inner and outer pouches, the face plate coupling means being secured to said flexible plate with the plane of said face plate coupling means generally parallel to the plane of said flexible plate and generally concentric with said aperture for receiving said stoma, one or more filters for deodorising flatus gas, and one or more flatus gas passages extending from the area located within said inner periphery and through said deodorising filter.
