Abstract
Disclosed herein are systems and methods for safe operation of a wound treatment apparatus with electronic components integrated on or within a wound dressing. In some embodiments, the electronic components include a power source, an isolation circuit, a controller, a capacitor, and a negative pressure source. The isolation circuit provides multiple activation states with at least one state preventing application of power to the other electronic components capable of storing electrical energy, thereby providing a safe operation of the apparatus. For example, sterilization of the apparatus can be performed safely.
