Abstract

The invention relates to an appliance for irrigation and/or drainage, which appliance comprising a body side member comprising an adhesive wafer for securing the appliance to the patient'"'"'s skin, said wafer can be provided with an aperture for receiving a stoma, surrounding a wound, a fistula or a drainage site, a wall of flexible material, the wall comprising a rear wall and a front wall, the rear wall being attached to the wafer and having an opening suitable for surrounding the surface area of the skin to be cleansed, and the front wall comprising a coupling flange adapted for removable coupling and sealing to matching coupling means, an sealed chamber which, when inflated, provides a distance between the adhesive wafer and the coupling flange.

Claims

1. An appliance for irrigation and/or drainage, which appliance comprising

a) a body side member comprising an adhesive wafer for securing the appliance to the patient'"'"'s skin, said wafer can be provided with an aperture for receiving a stoma, surrounding a wound, a fistula or a drainage site,

b) a wall of flexible material, the wall comprising a rear wall and a front wall, the rear wall being attached to the wafer and having an opening suitable for surrounding the surface area of the skin to be cleansed, and the front wall comprising a coupling flange adapted for removable coupling and sealing to matching coupling means, the wall and the body side member defining a reservoir,

c) a sealed chamber, being separate from the reservoir, which, when inflated, provides a distance between the adhesive wafer and the coupling flange.

2. An appliance according to claim 1 wherein the sealed chamber, when inflated, supports at least one of the walls.

3. An appliance according to any of the preceding claims wherein the sealed chamber, when inflated, supports the rear wall.

4. An appliance according to any of the preceding claims wherein the sealed chamber, when inflated, supports the front wall.

5. An appliance according to any of the preceding claims wherein the sealed chamber is provided with a valve.

6. An appliance according to any of the preceding claims wherein the sealed chamber constitutes a part of the wall.

7. An appliance according to any of the preceding claims wherein the sealed chamber is next to the coupling flange.

8. An appliance according to any of claims 1-6 wherein the sealed chamber is next to the adhesive wafer.

9. An appliance according to any of the preceding claims wherein the wall is provided with an opening.

10. An appliance according to any of the preceding claims wherein the wall is provided with an inlet and/or outlet opening.

11. An appliance according to any of the preceding claims wherein the sealed chamber can be inflated and deflated during use of the appliance.

12. An appliance according to any of the preceding claims wherein the wafer is provided with an aperture corresponding to the contour of the stoma, fistulae or wound.

13. An sealed chamber for use with an appliance for irrigation and/or drainage, which appliance comprising

a) a body side member comprising an adhesive wafer for securing the appliance to the patient'"'"'s skin, said wafer or pad can be adapted for receiving a stoma, surrounding a wound, a fistula or a drainage site,

b) a wall of flexible material, the wall comprising a rear wall being attached to the wafer and having an opening suitable for surrounding the surface area of the skin to be cleansed and a front wall being provided with a coupling flange, the wall and the body side member defining a reservoir and

c) wherein the sealed chamber is separate from the reservoir, and can be inflated by filling with a fluid, said chamber, when inflated, provides a distance between the adhesive wafer and the coupling flange.

14. A sealed chamber according to claim 13 wherein the chamber is an integrated part of the appliance.

15. A sealed chamber according to claim 13 wherein the chamber is a separate unit.

16. A sealed chamber according to any of claims 13-15 wherein the chamber substantially encircles the wall of the appliance.

17. A sealed chamber according to any of claims 13-16 wherein the chamber is provided with a valve.

18. A sealed chamber according to any of claims 13-17 wherein the chamber has the shape of an open ring.

19. A sealed chamber according to claim 18 wherein the ring is provided with means for connecting the open ends.

20. A sealed chamber according to claim 19 wherein the means for connecting is in the form of a mechanical lock, adhesive or Velcro.
