Abstract

An ostomy coupling including a body-side coupling member, an appliance-side coupling member including plural fastener lugs, and a bracing member. The lugs flex independently of each other to provide plural independent latching fastenings. The bracing member is moved between a bracing position in which the bracing member locks the lugs by resisting flexing movement, and a non-bracing or dismounted position in which the lugs are free to flex. The ostomy coupling is used with an ostomy pouch or with a controlled evacuation device.

Claims (12)

1. An ostomy appliance coupling comprising:

a. a body-side coupling member;

b. an appliance-side coupling member capable of coupling to and decoupling from the body-side coupling member, the appliance-side coupling member including a plurality of flexible fastener lugs for latching engagement with the body-side coupling member, each of said fastener lugs being capable of flexing independently of the other lugs;

c. an annular, continuous, non-dynamic, and integral bracing member on the body-side coupling member moveable so as to be positionable in a bracing position or a non-bracing position, in a bracing position the bracing member braces said flexible fastener lugs so as to resist outward flexing of the flexible lugs and brace said appliance-side and body-side coupling members together, in a non-bracing position the bracing member is demounted from the appliance-side coupling member so as not to brace the flexible fastener lugs and permit decoupling of the coupling members; and

d. a grippable tab projecting outwardly from said bracing member proximate to at least one fastener lug, said tab being grippable and manipulatable for applying a flexing force to said at least one fastener lug for separating the appliance-side coupling member from said body-side coupling member.

2. The ostomy appliance coupling according to claim 1 , wherein each of the flexible fastener lugs comprises a latch profile.

3. The ostomy appliance coupling according to claim 1 , further comprising a positive engagement device for positively retaining the bracing member in a bracing position on the appliance-side coupling member.

4. The ostomy appliance coupling according to claim 3 , wherein the positive engagement device comprises co-operating surfaces of the bracing member and the appliance-side coupling member.

5. The ostomy appliance coupling according to claim 4 , wherein the co-operating surface of the appliance-side coupling member is a surface of a respective lug.

6. The ostomy appliance coupling according to claim 4 , wherein the appliance-side coupling member comprises a wall segment between adjacent lugs, and wherein the co-operating surface of the appliance-side coupling member is a surface of the wall segment.

7. The ostomy appliance coupling according to claim 6 , wherein said surface of the wall segment projects radially of the adjacent lugs.

8. The ostomy appliance coupling according to claim 7 , wherein said co-operating surface of the bracing member comprises a projection having an arcuate length longer than an arcuate length of each lug.
