Abstract: An ostomy pouch (10) includes a front wall (12) provided with a comfort layer (16) and a vent (22). An apertured cover layer (24) is secured to the front wall (12) through the comfort layer (16) to define a chamber for a filter element (28) and to provide a smooth surface to which can be applied an adhesive sticker. The cover layer (24) includes a plurality of apertures (30), and the flow rate through the vent can be controlled by positioning the sticker to selectively block one or more of the apertures (30). An adhesive wafer (40) includes both circular and non-circular (race-track) cut-out guidelines for enabling the aperture to be cut to any desired shape and size. The wafer (40) is secured to the pouch along a weld line having a shape corresponding to a combined circular and race-track silhouette.

Abstract: A tap (14) for a drainage bag (10) is provided which can be welded to the bag material with the tap in a ready-assembled condition. The tap includes an integral attachment portion (20) and a housing (18). An L-shaped tubular tap member (16) with a handle (30) is inserted in an aperture of the housing (18), and is rotatable in the aperture between a closed position in which the outlet (22) points upwardly, and an open position in which the outlet (22) points downwardly. In the closed position, a peripheral region (54) of the attachment portion (20) projects beyond the tap member (16) on all sides, to enable the assembled tap to be welded to the bag material.
