ABSTRACT:
An ostomy device for releasably connecting an ostomy bag to an adhesive backed label including a mounting member for connecting one of two coupling parts to the label. The mounting member comprises an expandable portion for facilitating displacement of the connected coupling part between a normal position and an expanded position. The expanded portion comprises a pair of accordion-like folds including an inner fold and a smaller outer fold. The connected coupling part comprises a rib portion having a deflectible sealing strip extending therefrom. The rib portion is connected to the mounting member adjacent the outer folds such that the sealing strip is positioned intermediate the inner and outer folds when the coupling part is in the normal position. The inner fold guides discharge from the stoma into the bag and away from the interengaged coupling parts. In an alternate embodiment, the mounting member is affixed to the label. A preferred method of mounting the plastic coupling ring to the thin plastic surface of the label includes heat welding the polyethylene mounting member to the polyethylene annular ring. The ring is affixed to the label using a hot melt adhesive. Before affixing the ring to the label a maximized stoma aperture is formed through the ring and mounting member leaving a relatively narrow inner edge sealing region.
