Abstract

An ostomy appliance for attachment to the stoma body comprising an adhesive wafer and a collecting pouch attachable to an adhesive wafer, the wafer comprises a backing layer and a skin-facing adhesive layer, wherein the adhesive skin-facing surface of the wafer is provided with a release liner covering the skin-facing surface of the adhesive layer, the release liner comprising at least a first part and a second part, the first and the second part being interconnected along a predefined folding line and wherein both the first and the second part of the release liner is in contact with the adhesive. The construction facilitates stepwise application.

Claims

1. An ostomy appliance for attachment to the stoma body comprising an adhesive wafer and a collecting pouch attachable to an adhesive wafer, the wafer comprises a backing layer and a skin-facing adhesive layer, wherein the adhesive skin-facing surface of the wafer is provided with a release liner covering the skin-facing surface of the adhesive layer, the release liner comprising at least a first part and a second part, the first and the second part being interconnected inseparably along a predefined folding line and wherein both the first and the second part of the release liner is in contact with the adhesive.

2. The ostomy appliance according to claim 1, wherein the adhesive is has a tensile strength at 20% strain of less than 0.75N/4 mm.

4. The ostomy appliance according to claim 1, wherein the predefined folding line extends from one edge portion of the wafer to another edge portion of the wafer.

5. The ostomy appliance according to claim 1, wherein the predefined folding line is linear.

6. The ostomy appliance according to claim 1, wherein the predefined folding line is a perforated line.

7. The ostomy appliance according to claim 1, wherein the predefined folding line is in the form of a line with reduced thickness.

8. The ostomy appliance according to claim 7, wherein the reduced thickness in the folding line is less than 80% of the overall thickness of the release liner.

9. The ostomy appliance according to claim 1, wherein the predefined folding line extends through a central portion of the release liner.

12. The ostomy appliance according to claim 1, wherein when the first part is released from the adhesive surface and folded at the predefined folding line and superimposed over the second part the first part of the release liner forms an acute angle relative to the second part of the of the release liner.

13. The ostomy appliance according to claim 1, wherein the release liner is provided with at least one ear extending beyond the adhesive surface of the wafer.

14. The ostomy appliance according to claim 1, wherein the release liner is provided with two ears extending beyond the adhesive surface, positioned on opposing edges thereof.

3. The ostomy appliance according to claim lany-ef-the-preseeting-slaims, wherein the predefined folding line is a weakened line.
