ABSTRACT:
The ostomy pouch is formed of a flexible plastic material with a waste inlet opening and a gas outlet opening proximate the waste inlet opening. The gas outlet opening is of a configuration and size that resists entry of outside water into the pouch through the gas outlet opening. A filter aligned with the gas outlet opening is bonded at a peripheral zone surrounding the gas outlet opening, leaving an unbonded area that communicates with the gas outlet opening. A free face of the filter is gas impermeable. Gases within the pouch pass through an exposed, gas permeable peripheral edge of the filter toward the center and exit into the unbonded section for evacuation through the gas outlet opening.
