Abstract
A method of detecting ostomy effluent leakage in an ostomy appliance is provided. The method includes the steps of providing a plurality of sensors; measuring resistance of the ostomy appliance using each of the plurality of sensors; entering resistance measurements in a ring buffer configured to hold resistance measurements; calculating a median resistance value of each of the plurality of sensors using the resistance measurements; comparing the median resistance value against a predetermined range of acceptable resistance values; increasing a leak count for a corresponding sensor when the median resistance value of the sensor is outside the predetermined range of acceptable resistance values; determining a leak state when the leak count increases beyond a predetermined acceptable leak count; and sending an alert upon a determination of a leak state.
