Abstract
Vented ostomy pouches are disclosed in which a first wall is securable to a patient's peristomal skin surfaces and the obverse second wall is provided with an outlet opening for the escape of gases from the pouch. A deodorizing gas filter extends over the outlet and a third wall, or internal barrier wall, is located within the pouch and divides it into two chambers. The barrier wall operates to block the passage of solids and most liquids from the first chamber to the second but is provided with at least one vent that permits the flow of gases into the second chamber from the first. A filter-protecting panel in the second chamber directs such gases along a circuitous route as they travel from the vent to the outlet. A connection, preferably in the form of a spot weld, joins the barrier wall to the bodyside first wall of the pouch at about the elevation of the filter to prevent the barrier wall from blocking against other surfaces and obstructing the flow of gases through the vent and filter.
