Abstract
An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.
Claims25
A method of detecting fill of an ostomy bag, the method comprising:
- under control of a hardware processor,
- sensing capacitance values of a plurality of capacitive sensors disposed between two layers of one of two walls of an ostomy bag in an array comprising a sensor layer, the sensor layer having an outline shaped and sized like the ostomy bag;
- calculating a level of the fill of the bag based at least in part on the capacitance values;
- and
- outputting an indication that a volume of bag fill has increased responsive to detecting change in the capacitance values due to effluent entering the bag.
