Abstract

For any ostomy appliance, a body-side ostomy member includes a medical grade adhesive pad and a coupling having one part captive to but telescopically slidable relative to another part to provide access for the fingers or thumb of a wearer beneath a lateral flange of the coupling, when the parts are spaced from one another.

This allows an ostomy coupling to be secured together without applying undue pressure to the sensitive body area of the wearer.

Claims

1. A body side ostomy member which includes a medical grade adhesive pad and a coupling ring means, said coupling ring means consisting of inner and outer concentric member means which are captive and slide telescopically with respect to another forming an integral coupling means, said inner concentric member means having a flange means with a resilient, flexible sealing strip means distal to said pad, said outer member means having a resilient flexible sealing strip means on a proximal end of said outer member means such that when the inner and outer member means are longitudinally extended apart with respect to each other, said sealing strip means limits the telescopic sliding movement of said outer and inner concentric member means and provides a space between said member means to enable a user'"'"'s thumb or fingers to be placed therebetween.

2. An ostomy member according to claim 1 in which said inner and outer concentric means have first and second walls which are parallel to and slideable with respect to one another, said inner concentric member including a stomal orifice which is substantially circular, and said first and second walls are substantially cylindrical.

3. An ostomy member according to claim 2 in which the first and second walls are located one within the other for telescopic sliding movement and the movement is limited by an arrangement of cooperating parts which also serve a sealing or anti-leakage function.

4. An ostomy member according to claim 3 in which one wall, the innermost is provided with an outwardly extending resilient flexible peripheral seal strip, and other wall, the outermost, is provided at its other end with an inwardly extending resilient flexible peripheral seal strip, each of these seal strips extending towards, and such that its distal portion engages the confronting surface of the other wall.

5. An ostomy member according to claim 4 in which the walls are substantially coaxial cylinders sliding one within the other and the inner is connected to (or integral with) the flange which is secured to the medical grade adhesive pad.

6. An ostomy member according to claim 2 in which the first and second walls are located one within the other for telescopic sliding movement and the movement is limited by an arrangement of cooperating prats which also serve a sealing or anti-leakage function.

7. An ostomy member according to claim 6 in which one wall, the innermost is provided with an outwardly extending resilient flexible peripheral seal strip, and other wall, the outermost, is provided at its other end with an inwardly extending resilient flexible peripheral seal strip, each of these seal strips extending towards the other, such that the distal portion of each engages the confronting surface of the other wall.

8. An ostomy member according to claim 7 in which the walls are substantially coaxial cylinders sliding one within the other and the inner is connected to (or integral with) the flange which secured to the medical grade adhesive pad.
