Method of detecting leakage in medical devices

A method of detecting leakage in a medical device, the method comprising the steps of:

• providing a plurality of sensors, wherein each the plurality of sensors is configured to measure resistance of the medical device;
• measuring resistance of the medical device using each of the plurality of sensors;
• entering resistance measurements in a ring buffer, wherein the ring buffer is configured to hold a current resistance measurement and at least one prior resistance measurement for each of the plurality of sensors;
• calculating a median resistance value of each of the plurality of sensors using the current resistance measurement and the at least one prior resistance measurement from each of the plurality of sensors;
• comparing the median resistance value of each of the plurality of sensors 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, wherein the predetermined acceptable leak count is greater than two;
• and
• sending an alert upon a determination of a leak state.
