Abstract
The disclosure relates to a system for determining and signalling moisture propagation in an adhesive material layer of a base plate and/or a sensor assembly part for an ostomy appliance. The disclosure further relates to aspects of a base plate and/or a sensor assembly part for an ostomy appliance and its use in such a system.
Claims20
A base plate for an ostomy appliance, comprising:
- an adhesive layer for attachment of the base plate to the skin surface of a user, wherein a stoma-receiving opening extends through the base plate at a center portion of the base plate;
- a sensor element comprising:
- a first sensor electrically connected to a control unit interface of the base plate and extending at least partly annularly around the stoma-receiving opening, the first sensor having a conductor electrode and a ground electrode;
- and
- a second sensor electrically connected to a control unit interface and located at a greater radial distance from the stoma-receiving opening than the first sensor, the second sensor having a conductor electrode and a ground electrode;
- and
- a backing layer, wherein at least a part of the sensor element is between the adhesive layer and a proximal surface of the backing layer.

A base plate for an ostomy appliance, comprising:
- a layer of an adhesive material adapted for attachment of the base plate to the skin surface of a user, wherein a stoma-receiving opening extends through the base plate at a center portion of the base plate;
- a sensor element comprising:
- a first sensor electrically connected to a control unit interface and having a conductor electrode and a ground electrode;
- and
- a second sensor electrically connected to the control unit interface and having a conductor electrode and a ground electrode, wherein the second sensor is located at a greater radial distance from the stoma-receiving opening than the first sensor;
- wherein each of the first sensor and the second sensor comprises:
- a detecting portion provided around the stoma-receiving opening;
- and
- an extension portion extending from the detecting portion of each sensor to the control unit interface;
- and
- a backing layer, wherein the first sensor and the second sensor are provided between the layer of adhesive material and a proximal surface of the backing layer.
