Abstract
A collection pouch for use by ostomates, the pouch being drainable to facilitate extended use of the pouch and including a gas venting and filtering assembly having a replaceable deodorizing filter element. A barrier film is disposed within the pouch to protect the filter element from contact with and possible obstruction by exudate. Interior wall surface areas of the double-chambered pouch are raised or embossed, and the filter assembly is internally ribbed, to insure that the pathway for the escape of gases from the pouch remains open.
