Abstract

Disclosed is an ostomy bag 1 having an outer rotatable adhesive fitting wafer 15 attached thereto. This offers a higher degree of customization to the user, as the user may cut the adhesive fitting wafer in such a way that it fits to the contour of the skin and the user may also rotate the ostomy bag relative to the wafer in order to achieve a desired orientation of the ostomy bag.

First claim

The invention claimed is:

1. An ostomy appliance comprising:
an ostomy bag comprising a proximal wall facing a user during use and a distal wall facing away from the user during use, wherein the proximal wall comprises an inlet opening through which output from a stoma is received during use;
a connecting flange comprising:
an annular attachment area having a through-going hole connecting at a distal end to and around the inlet opening of the proximal wall; and
a radial extension on a proximal end of the through-going hole of the annular attachment area; and

an adhesive fitting wafer attached around the through-going hole of the annular attachment area between the distal end of the through-going hole and the proximal end of the through-going hole, the adhesive fitting wafer being positioned between and substantially parallel to each of the proximal wall and the radial extension of the connecting flange, wherein the adhesive fitting wafer is rotatable around the through-going hole of the annular attachment area in a direction substantially parallel relative to the connecting flange,
wherein the adhesive fitting wafer includes a high tack adhesive disposed on substantially an entirety of a proximal side of the adhesive fitting wafer, with the high tack adhesive being configured to adhere and to conform the proximal surface of the adhesive fitting wafer to a contour of a skin surface of the user, and to adhere to substantially an entirety of a distal surface of the connecting flange around the proximal end of the through-going hole.

2. The ostomy appliance according to claim 1 , wherein the connecting flange is an adhesive coupling wafer.

3. The ostomy appliance according to claim 2 , wherein the adhesive coupling wafer is a base plate including the high tack adhesive on the proximal side of the radial extension for attachment to the skin surface.

4. The ostomy appliance according to claim 1 , wherein the connecting flange is a mechanical coupling flange for coupling with a complementary mechanical coupling flange of an ostomy device base plate.

5. The ostomy appliance according to claim 1 , wherein the adhesive fitting wafer is rectangular and has a width of at least three times a diameter of the radial extension of the connecting flange and a height of at least twice the diameter the radial extension of the connecting flange.

6. The ostomy appliance according to claim 1 , further comprising a release liner covering the adhesive on the proximal side of the adhesive fitting wafer and wherein the release liner has a split formed in the release liner.

7. The ostomy appliance according to claim 1 , wherein the adhesive fitting wafer is defined between an inner periphery located at the through-going hole of the annular attachment area and an outer periphery located at a distance from the inner periphery.

8. The ostomy appliance according to claim 1 , wherein the high tack adhesive is configured to adhere to the radial extension of the connecting flange and to the skin surface of the user.

9. The ostomy appliance according to claim 1 , further comprising an adhesive disposed on a proximal side of the radial extension of the connecting flange.

10. The ostomy appliance according to claim 1 , wherein the high tack adhesive is configured to adhere to the radial extension of the connecting flange.

11. The ostomy appliance according to claim 1 , wherein the adhesive fitting wafer is formed as a thin sheet.

12. The ostomy appliance according to claim 7 , wherein the high tack adhesive extends between the inner periphery and the outer periphery of the adhesive fitting wafer.

13. The ostomy appliance according to claim 1 , wherein the adhesive fitting wafer includes a backing layer with the high tack adhesive disposed on a side of the backing layer facing the connecting flange.

14. The ostomy appliance according to claim 1 , wherein an external surface of the proximal side of the adhesive fitting wafer consists essentially of the high tack adhesive.

15. The ostomy appliance according to claim 1 , wherein the proximal wall and the radial extension of the connecting flange form a recess therebetween with the adhesive fitting wafer being positioned within the recess between the proximal wall and the radial extension of the connecting flange.
