Coupling for an ostomy bag
First Claim
1. A coupling for joining a pad or dressing to an ostomy bag including first and second coupling elements each of closed loop form to define a stoma aperture therein, the first element being constructed so that it can be fixed to the pad or dressing and the second element being constructed so that it can be fixed to one wall of an ostomy bag, in which the first element includes an inner wall which continuously encircles the aperature and a series of projecting members uniformly radially spaced from the inner wall and located in an array which surrounds the inner wall, and in which the second element includes a rib member encircling the aperture for making sealing engagement, when the coupling elements are joined, with the outer surface of the inner wall, the coupling also having as a third element an annular ring which is constructed to be snap-fitted to the body side coupling element to extend radially outwardly therefrom whereby a wearer can place thumbs between the ring and body to support the first coupling element against the inwardly-directed force applied when coupling the first and second coupling elements together to attach the bag to the pad.

Abstract
A coupling for joining a pad or dressing to an ostomy bag includes coupling elements each of closed loop form, usually circular to define a stoma aperture therein, the body side element being constructed so that it can be fixed to the pad or dressing and the bag side element being constructed so that it can be fixed to one wall of an ostomy bag. The body side element includes an inner wall which continuously encircles the aperture and a series of projecting members uniformly radially spaced from the inner wall and located in an array which surrounds the inner wall. The bag side element includes a rib member encircling the aperture for making sealing engagement, when the coupling elements are joined, with the outer surface of the inner wall. The coupling also has an annual ring which is constructed to be snap-fitted to the body side coupling element to extend radially outwardly therefrom. In use, the wearer places his thumbs under the ring to support the body side coupling element against the inwardly-directed force applied when fitting a new bag.
