Abstract
Disclosed is an ostomy device with an adhesive wafer for attachment to a skin surface of a user and a collecting bag for collecting output from a stoma. The collecting bag is connected to the adhesive wafer, and the adhesive wafer has a through-going hole for accommodating the stoma of the user. The adhesive wafer includes a backing layer, a first switchable adhesive composition (11), a second absorbent adhesive composition (12), and a release liner.

An ostomy device comprising an adhesive wafer for attachment to a skin surface of a user, and a collecting bag connected to the adhesive wafer;
- the adhesive wafer having a through-going hole for accommodating the stoma of the user;
- and the adhesive wafer comprising a backing layer, a first switchable adhesive composition, a second absorbent adhesive composition, and a release liner, wherein the adhesive wafer has a central part adjacent to the hole for accommodating the stoma and a peripheral part adjacent to an edge of the adhesive wafer away from the hole, and wherein the second absorbent adhesive composition is located at least in the central part of the adhesive wafer, wherein the release liner is in contact with the first switchable adhesive composition in the peripheral part of the adhesive wafer, and wherein the release liner is in contact with the second absorbent adhesive composition in the central part of the adhesive wafer.
