1. An 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 configured to be positioned over the first layer;
a vacuum pump configured to apply vacuum pressure to the wound to draw the wound fluid away from the wound, wherein the vacuum pump is configured to be positioned within the wound dressing;
a pressure sensor configured to detect pressure within the wound dressing, the pressure sensor configured to be disposed beneath the second layer;
a controller configured to control the vacuum pump, the controller configured to be positioned external to the wound dressing, wherein the vacuum pump is configured to wirelessly communicate with the controller; and
an electrical wiring configured to electrically connect the pressure sensor with the controller,wherein the second layer includes a port in fluid communication with the first layer, andwherein the electrical wiring is configured to be passed through a channel formed in a wall of the port.

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.
