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 comprising:

a) a body side member including an adhesive wafer for securing the appliance to a patient'"'"'s skin, said adhesive wafer defining an aperture for receiving a stoma or a drainage site;

b) a front wall and a rear wall of flexible material, the rear wall being attached to the wafer and having an opening providing access to a surface of skin to be cleansed, and the front wall attached to a coupling flange adapted for removable coupling with a matching coupling member, the walls and the body side member defining a flexible reservoir that extends between the wafer and the coupling flange; and

c) a sealed chamber separate from the adhesive wafer that defines the aperture, the sealed chamber inflatable to provide a distance of separation between the adhesive wafer and the coupling flange.

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

3. The appliance according to claim 1 wherein the sealed chamber, when inflated, supports the rear wall.

4. The appliance according to claim 1 wherein the sealed chamber, when inflated, supports the front wall.

5. The appliance according to claim 1 wherein the sealed chamber is provided with a valve.

6. The appliance according to claim 1 wherein the sealed chamber constitutes a part of at least one of the front wall or the rear wall.

7. The appliance according to claim 1 wherein the sealed chamber is next to the coupling flange.

8. The appliance according to claim 1 wherein the sealed chamber is next to the adhesive wafer.

9. The appliance according to claim 1 wherein at least one of the front wall or the rear wall is provided with an opening.

10. The appliance according to claim 1 wherein at least one of the front wall or the rear wall is provided with an inlet/outlet opening.

11. The appliance according to claim 1 wherein the sealed chamber can be inflated and deflated during use of the appliance.

12. The appliance according to claim 1 wherein the wafer is provided with an aperture corresponding to a contour of the stoma.

13. A sealed chamber for use with an appliance for irrigation and/or drainage, the appliance including a body side member having an adhesive wafer for securing the appliance to a patient'"'"'s skin, said wafer being adaptable to receive a stoma or a drainage site, a first wall attached to the wafer and having an opening suitable for surrounding the surface area of the skin to be cleansed and a second wall provided with a coupling flange, the walls and the body side member defining a flexible reservoir that extends between the wafer and the coupling flange, said sealed chamber separate from the adhesive wafer and configured to be inflated with a fluid, said sealed chamber, when inflated, providing a distance of separation between the adhesive wafer and the coupling flange.

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

15. The sealed chamber according to claim 13 wherein the chamber is a separate unit relative to the appliance.

16. The sealed chamber according to claim 13 wherein the chamber substantially encircles the walls of the appliance.

17. The sealed chamber according to claim 13 wherein the chamber is provided with a valve.

18. The sealed chamber according to claim 13 wherein the chamber is shaped as an open ring having open ends.
