  • Patent number: 5672163
    Abstract: The pouch is formed of first and second thin barrier film walls welded along the periphery to form a waste receptacle. One wall has an inlet defined by an attachment ring. The ring mounts the pouch on an adhesive faceplate adapted to adhere to the skin surrounding the stoma. A membrane, formed of material which is gas permeable but transmits little moisture and no liquid, is situated between the walls to separate the receptacle into an inlet chamber, where solids, liquid and most moisture are retained, and an outlet chamber into which gas and a small amount of vapor passes. A filter is provided to permit the gas to exit the outlet chamber. A first section of superabsorbent material isolates the filter from the outlet chamber. By absorbing any moisture in the gas before it contacts the filter, blockage of the filter is prevented.
