<p>Ostomy pouch comprises pouch envelope formed of flexible plastic material defining waste collection chamber for body waste that passes through a stoma; waste inlet opening formed in the envelope for positioning around stoma to permit passage of waste material from the stoma to the collection chamber; and flexible annular pouch coupling mechanism on the pouch envelope at the waste inlet opening. An ostomy pouch (12) comprises a pouch envelope (16) formed of flexible plastic material defining a waste collection chamber for body waste that passes through a stoma (120); waste inlet opening (32) formed in the envelope for positioning around the stoma to permit passage of waste material from the stoma to the collection chamber; and flexible annular pouch coupling mechanism on the pouch envelope at the waste inlet opening. The coupling mechanism has a resealable coupling adhesive and support for the resealable adhesive for avoiding wrinkling of the resealable coupling adhesive when the coupling mechanism is flexed or separated from a coupling bond with a body-side mounting wafer (14), the support including a foam layer joined to an outside surface of the pouch envelope. An independent claim is also included for a body-side mounting wafer comprising multi-layer assembly having an opening for a stoma, and having a biocompatible adhesive layer on one side for securement to a body surface around the stoma, and an opposite side with a release film for detachable engagement with a pouch to be mounted on the wafer, the assembly further including support for the release film for avoiding wrinkling of the release film when the release film is flexed or is separated from a coupling bond with the pouch.</p> |
