Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
176 words
An ostomy pouch comprising two pouch walls of moisture proof, odor proof polymeric materials sealed together along at least a substantial portion of their peripheral edge to form said pouch, one of said pouch walls having an aperture adapted in use to fit around the stoma of the user, said stomal aperture encircled by means for attaching said pouch to the body of the user, the second pouch wall having an aperture in its upper region above the stomal opening in the first pouch wall so that fecal matter discharged from the stoma into the pouch will not readily contact said second pouch wall aperture, a filter element comprising a polymeric film cover having an aperture and an insert of gas deodorizing material, and said film cover affixed to said second pouch wall so that opposite ends of said insert of gas deodorizing material overlie said second pouch wall and said film cover apertures whereby gas within the pouch travels into said filter element and through said gas deodorizing material before being vented to the atmosphere.
