Abstract

A single-use ostomy appliance is described including an ostomy coupling for releasable coupling first and second portions at a stomal orifice. The two portions may be separable body-side and non-body-side parts, or the two portions may be portions of a unitary ostomy device such as a controlled evacuation device. The coupling includes a mechanical fastener configured such that the coupling is rendered substantially not resecurable after the fastener is released.

Claims

1. An ostomy coupling comprising:

a. a first coupling member;

b. a second coupling member having a stomal opening; and

c. a first mechanical fastening device for releasably securing the first and second coupling members together, the fastening device being configured such that the fastening device becomes substantially non-operational after the first time that the fastening device is released to allow disengagement of the first and second coupling members, whereby the first and second coupling members are not resecurable together thereafter.

2. The ostomy coupling according to claim 1, wherein at least one coupling member comprises a stomal opening or a stomal recess.

3. The ostomy coupling according to claim 1, wherein one coupling member is a non-body-side coupling member.

4. The ostomy coupling according to claim 1, wherein the fastening device comprises a weak portion that is configured to be permanently deformed or broken in order to release the fastening device to allow disengagement of the coupling member.

5. The ostomy coupling according to claim 4, wherein the weak portion comprises a frangible portion that is configured to be permanently broken.

6. The ostomy coupling according to claim 4, wherein the weak portion comprises a portion of a wall of the coupling member.

7. The ostomy coupling according to claim 4, wherein the weak portion extends only partway across a width of the coupling member, such that the coupling member is not split entirely across its width.

8. The ostomy coupling according to claim 1, wherein the fastening device comprises a hoop member that is configured to be permanently deformed or broken in order to release the fastening device to allow disengagement of the coupling member.

9. The ostomy coupling according to claim 1, wherein the fastening device comprises a bracing band that is configured to be permanently deformed or broken in order to remove the bracing effect to allow disengagement of the coupling member.

10. The ostomy coupling according to claim 1, further comprising:

a. a third coupling member; and

b. a second mechanical fastening device for releasably securing the third coupling member to at least one of the first and second coupling members.

11. The ostomy coupling according to claim 10, wherein the first fastening device is configured to provide mechanical bracing support for the second fastening device.

12. The ostomy coupling according to claim 11, wherein the first and second coupling members form part of a unitary ostomy device, and wherein the third coupling member is a body-side coupling member for mounting the unitary device on a wearer'"'"'s body.

13. The ostomy coupling according to claim 12, wherein the first fastening device comprises a weak portion that is configured to be permanently deformed or broken in order to release the first fastening device to allow disengagement of the first and second coupling members.

14. The ostomy coupling according to claim 13, wherein the weak portion comprises a frangible portion that is configured to be permanently broken.

15. The ostomy coupling according to claim 13, wherein the weak portion comprises a portion of a wall of one of the coupling members.

16. The ostomy coupling according to claim 13, wherein the weak portion extends only partway across a width of one of the coupling members, such that said coupling member is not split entirely across its width.

17. The ostomy coupling according to claim 1, wherein the fastening device comprises a hoop member that is configured to be permanently deformed or broken in order to release the fastening device to allow disengagement of the first and second coupling members.

18. The ostomy coupling according to claim 1, wherein the fastening device comprises a bracing band that is configured to be permanently deformed or broken in order to remove the bracing effect to allow disengagement of the first and second coupling members.

19. An ostomy appliance comprising an appliance for use by a person with a stomal orifice, and an ostomy coupling for releasably securing a first portion of the appliance to a second portion of the appliance around the stomal orifice, the ostomy coupling comprising a first mechanical fastening device for releasably securing the first and second portions together, the fastening device being configured such that the fastening device becomes substantially non-operational after the first time that the fastening device is released to allow disengagement of the first and second portions, whereby the first and second portions are not resecurable together thereafter by the first fastening device.

20. The ostomy appliance according to claim 19, wherein one of the first and second portions comprises a body-side mounting member, and the other of the first and second portions comprises a disposable ostomy device intended for single use.

21. The ostomy appliance according to claim 19, wherein the first and second portions are respective portions of a unitary disposable ostomy device intended for single use.

22. The ostomy appliance according to claim 21, wherein the unitary disposable ostomy device comprises an intermediate member permanently joined to both the first and second portions.

23. The ostomy appliance according to claim 22, wherein the intermediate member comprises a collapsible collection container.

24. The ostomy appliance according to claim 21, further comprising a body-side mounting device, and a second mechanical fastening device for releasably fastening at least one of the first and second portions to the body-side mounting device.

25. The ostomy appliance according to claim 24, wherein the first mechanical fastening device is configured to provide, in use, mechanical bracing support to the second mechanical fastening device.

26. The ostomy appliance according to claim 24, wherein the first mechanical fastening device is configured, in use, to be released in order to disengage the first and second portions of the appliance prior to release of the second mechanical fastening device.

27. The ostomy appliance according to claim 21, wherein disengagement of the first mechanical fastening device transforms the unitary disposable ostomy appliance from a first operation state to a second operation state.

28. The ostomy appliance according to claim 27, wherein the first operation state is a compact state, in which the appliance has a reduced collection volume for stomal waste.

29. The ostomy appliance according to claim 27, wherein the second operation state is an enlarged state, in which the appliance has an enlarged collection volume for stomal waste.
