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, a second adhesive composition, and a release liner. The first adhesive is contained in a recess in the device. The first switchable adhesive composition comprises a polymer and a switch initiator, and can be switched from a first liquid state to a second adhesive state by activation of the switch initiator.
