Claims24
An ostomy appliance for attachment around a stoma of a user, the appliance comprising:
- a carrier sheet having a proximal surface and a distal surface and a through-going hole extending through the carrier sheet from the proximal surface to the distal surface;
- a first adhesive material disposed on the proximal surface of the carrier sheet and configured to adhere the appliance to a peristomal skin surface of the user;
- a second material disposed at least on a portion of the distal surface of the carrier sheet, the second material configured to dissipate in response to exposure to stomal fluids;
- and
- a signal generator in communication with the second material and adapted to provide an indicator signal when dissipation of the second material reaches a pre-defined threshold value.
