Abstract
Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a wound dressing, negative pressure source, switch, interface element, and control circuitry. The negative pressure source, switch, and interface element can be disposed on or within the wound dressing. The control circuitry can be in a first or second mode. In the first mode, the control circuitry can cause supply of negative pressure in response to a first user input via the switch when the negative pressure source is not supplying negative pressure and prevent supply of negative pressure in response to the first user input while the negative pressure source is supplying negative pressure, and the control circuitry can change from the first mode to a second mode in response to a second user input via the interface element. In the second mode, the control circuitry can disable supply of negative pressure.
