Temperature detection and protection for negative pressure wound therapy systems

A negative pressure wound therapy system comprising:

• a wound dressing configured to be placed over a wound, the wound dressing configured to absorb fluid aspirated from the wound;
• a negative pressure source disposed on or within the wound dressing, the negative pressure source configured to aspirate fluid from the wound;
• an electronic control circuitry disposed on or within the wound dressing and configured to operate the negative pressure source;
• a power source disposed on or within the wound dressing and configured to provide power to the negative pressure source and the electronic control circuitry;
• and
• an integrated circuit disposed on or within the wound dressing and configured to receive power from the power source, the integrated circuit comprising an electronic protection circuitry configured to:
• monitor a temperature of the power source;
• responsive to the temperature satisfying at least one temperature threshold, cause the electronic control circuitry to adjust operation of the negative pressure source or prevent supply of power from the power source;
• and
• responsive detection of at least one of a reverse current condition or an excessive current condition, prevent supply of power from the power source.
