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.
Claims45
A base plate for an ostomy appliance, comprising:
- at least a first layer of an adhesive material adapted for attachment of the base plate to the skin surface of a user;
- a backing layer comprising a film material forming a distal and a proximal surface of the backing layer;
- wherein a stoma-receiving opening extending through the base plate is provided in a center portion of the base plate;
- and
- a first sensor element comprising at least one sensor pair, the sensor pair comprising a first sensor and a second sensor, each of the first sensor and the second sensor connected to a control unit interface, such that an electrical signal can be conducted between the first sensor and the second sensor and the control unit interface, wherein the first sensor extends at least partly annularly around the stoma-receiving opening;
- wherein the first sensor and the second sensor are provided between the first layer of adhesive material and the proximal surface of the backing layer;
- wherein each of the first sensor and the second sensor comprises a conductor electrode and a ground electrode;
- and
- wherein the second sensor is located at a greater radial distance from the stoma-receiving opening than the first sensor.
