1. A negative pressure wound therapy apparatus comprising:
- a wound dressing configured to enclose a wound and provide a seal around a perimeter of the wound, the wound dressing comprising a first layer and a second layer arranged in superposed relation, the first layer configured to absorb and capture wound fluid and the second layer positioned over the first layer;
a pump system comprising;
a vacuum pump configured to apply vacuum pressure to the wound to draw wound fluid away from the wound, wherein the vacuum pump is positioned within the wound dressing;
a pressure sensor configured to detect pressure within the wound dressing, the pressure sensor positioned within the wound dressing;
a controller configured to control the vacuum pump,wherein the pump system is configured to communicate wirelessly with an external electronic device.

Abstract
The composite wound dressing apparatus promotes healing of a wound via the use of a vacuum pump. The vacuum pump applies a vacuum pressure to the wound to effectively draw wound fluid or exudate away from the wound bed. The vacuum pump is tethered to the wound dressing and is portable, preferably, carried by the patient in a support bag, which permits patient mobility. Moreover, the patient does not need to be constrained for any period of time while exudate is being removed from the wound.
