A recently granted patent (Publication Number: US11918506B2) discloses a base plate for a medical appliance that includes selective sensor points. The base plate comprises a first adhesive layer with a stomal opening, a proximal surface for attachment to a user's skin, and multiple sensor point openings arranged around a center point. Additionally, a plurality of electrodes are located distally of the first adhesive layer, forming leak sensors by aligning with specific sensor point openings. Each sensor point opening extends through the adhesive layer, exposing sensing parts of the electrodes. The patent also describes a method for manufacturing the base plate, involving the formation of the adhesive layer, arrangement of electrodes, and the inclusion of a masking element for insulation.

Furthermore, the patent details the inclusion of a masking element between the adhesive layers, with the masking element being more insulative than the first adhesive layer. The sensor point openings are arranged circumferentially around the center point at specific radial distances, with the electrodes forming leak sensors by aligning with these openings. The method of manufacturing the base plate involves precise positioning of the electrodes and sensor point openings to ensure accurate sensing capabilities. Overall, the patent highlights a novel base plate design for medical appliances that incorporate selective sensor points and leak sensors for enhanced functionality and user experience.
