<p>A coupling for joining a pad or dressing to an ostomy bag includes coupling elements (18, 48) each of closed loop form, usually circular to define a stoma aperture (23) therein, the body side element (18) being constructed so that it can be fixed to the pad or dressing and the bag side element (48) being constructed so that it can be fixed to one wall of an ostomy bag. The body side element (18) includes an inner wall (21) which continuously encircles the aperture (23) and a series of projecting members (24) uniformly radially spaced from the inner wall (21) and located in an array which surrounds the inner wall (21). The bag side element (48) includes a rib member (50) encircling the aperture (23) for making sealing engagement, when the coupling elements (18, 48) are joined, with the outer surface of the inner wall (27). The coupling also has an annual ring (8) which is constructed to be snap-fitted to the body side coupling element (18) to extend radially outwardly therefrom. In use, the wearer places his thumbs under the ring (8) to support the body side coupling element (18) against the inwardly-directed force applied when fitting a new bag.</p> |
