Ostomy appliance with layered base plate

A base plate of an ostomy appliance, the base plate comprising:

• a first adhesive layer comprising a proximal surface configured to be attached to a skin surface of a user and a plurality of openings extending entirely through the first adhesive layer, the plurality of openings comprising a stomal opening with a center point and at least two sensor point openings, wherein a first sensor point opening of the at least two sensor point openings is spaced from the center point by a radial distance and a second sensor point opening of the at least two sensor point openings is spaced from the center point by the radial distance;
• a masking layer arranged on a distal surface of the first adhesive layer, wherein the masking layer is more insulative than the first adhesive layer;
• and
• a plurality of electrodes arranged on a distal side of the first adhesive layer, each electrode including a sensing part and a conductor part, wherein the masking layer is arranged between the conductor parts and the first adhesive layer, the plurality of electrodes forming a first resistive pair of electrodes and a second resistive pair of electrodes, wherein each resistive pair of electrodes includes an electrode part of a ground electrode.

• a masking layer arranged on a distal surface of the first adhesive layer, wherein the masking layer is more insulative than the first adhesive layer;
• and
• an electrode layer printed entirely on a proximal surface of a separate flexible support film, the electrode layer arranged on a distal side of the first adhesive layer and the masking layer being arranged proximal to the electrode layer, each electrode including a sensing part and a conductor part;
• a second adhesive layer, wherein the masking layer, the electrode layer, and the separate flexible support film are arranged between the first adhesive layer and the second adhesive layer, and
• wherein the first adhesive layer comprises a plurality of openings extending entirely through the first adhesive layer, wherein the masking layer comprises a plurality of mask openings extending entirely through the masking layer, and wherein each opening of the plurality of openings of the first adhesive layer overlaps an opening of the plurality of mask openings of the masking layer and a sensing part of the plurality of electrodes to form a sensor point, wherein the sensing part does not extend into the opening of the plurality of mask openings.
