Abstract

A controlled evacuation ostomy appliance includes an attachment device for attaching the appliance to a wearer, a seal for sealing against stomal tissue, and a restrainer. The restrainer restrains the seal relative to the attachment device and transfers a sealing force (or its reaction) between the attachment device and the seal.

Claims

1. A controlled evacuation ostomy appliance comprising:

a. an attachment device for attaching the appliance to the wearer'"'"'s body;

b. a seal for sealing against a wearer'"'"'s stoma to obstruct discharge of body waste from the stoma; and

c. a restraining structure for restraining the seal with respect to the attachment device and for transferring a sealing force or a sealing force reaction between the attachment device and the seal, the restraining device comprising a flexible portion.

2. The appliance according to claim 1, wherein, in use, the flexible portion of the restraining structure acts in tension in order to transfer said sealing force or sealing force reaction.

3. The appliance according to claim 1, wherein the restraining structure is substantially entirely flexible.

4. The appliance according to claim 1, wherein the restraining structure further comprises a substantially non-flexible portion.

5. The appliance according to claim 4, wherein the non-flexible portion comprises a peripheral wall, and the flexible portion comprises a rear portion supported by the peripheral wall.

6. The appliance according to claim 4, wherein the non-flexible portion comprises a rear wall portion, and the flexible portion comprises a flexible intermediate portion between the rear wall portion and the attachment device.

7. The appliance according to claim 1, wherein the flexible portion is substantially inelastic.

8. The appliance according to claim 1, wherein the restraining structure substantially covers the seal.

9. The appliance according to claim 1, wherein the restraining structure partly covers the seal.

10. The appliance according to claim 1, wherein the restraining structure, at least when in use, has a dome shape.

11. A controlled evacuation ostomy appliance, comprising:

a. an attachment device for attaching the appliance to the wearer'"'"'s body;

b. a seal for sealing against a wearer'"'"'s stoma to obstruct discharge of body waste from the stoma; and

c. a restraining structure for restraining the seal with respect to the attachment device and for transferring a sealing force or a sealing force reaction between the attachment device and the seal, wherein the restraining structure partly covers the seal.

12. The appliance according to claim 11, wherein the restraining structure comprises a flexible portion.

13. The appliance according to claim 12, wherein the flexible portion comprises at least one strap or mesh, and defines an open structure.

14. The appliance according to claim 11, wherein the restraining structure is cage-like or frame-like.

15. The appliance according to claim 11, wherein the restraining structure comprises one or more apertures.

16. A controlled evacuation ostomy appliance comprising:

a. an attachment device for attaching the appliance to the wearer'"'"'s body;

b. a seal for sealing against a wearer'"'"'s stoma to obstruct discharge of body waste from the stoma; and

c. a restraining structure for restraining the seal with respect to the attachment device and for transferring a sealing force or a sealing force reaction between the attachment device and the seal, wherein the restraining structure has a dome-shape at least in use.

17. The appliance according to claim 16, wherein the restraining structure comprises a flexible portion.

18. The appliance according to claim 16, wherein the restraining structure defining the dome-shape is substantially rigid.
