Claim of US Patent No. 10,987,243

1. A method of operating an ostomy device, comprising:providing, in the ostomy device, a first electrode separated from a patient by a first adhesive layer having a first surface and a second surface, wherein the second surface opposes the first surface, wherein the first surface is configured to attach the ostomy device to the patient, the first electrode having a ring shape that encircles a stoma opening and separated from the patient by the first adhesive layer, wherein a second electrode has a ring shape that encircles the first electrode and is separated from the patient by the first adhesive layer, wherein the ring-shaped portion of the first electrode and the ring-shaped portion of the second electrode are distal the first adhesive layer and in contact with the second surface of the first adhesive layer such that fluid emanating in any direction from the stoma opening and absorbed by the first adhesive layer can be sensed via a change in resistance in the first adhesive layer, wherein a second adhesive layer has a third surface and a fourth surface, wherein the fourth surface opposes the third surface, wherein a portion of the third surface adheres to a portion of the second surface, and wherein the first electrode and the second electrode are proximal the third surface of the second adhesive layer;
detecting changes in resistance between the first electrode and the second electrode; and
activating an alarm based upon detecting the changes in the resistance.
