Abstract
Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a wound dressing, negative pressure source, user interface, sensor, and control circuitry. The user interface can receive an activation input. The sensor can detect whether the wound dressing is positioned over a wound. The control circuitry can cause supply of negative pressure in response to receipt of the activation input and a determination that the sensor detects that the wound dressing is positioned over the wound. In addition, the control circuitry can prevent supply of negative pressure in response to a determination that the sensor does not detect that the wound dressing is positioned over the wound.
