Abstract:
1. An apparatus for treating a wound, comprising: a conformable wound dressing comprising a backing layer, wherein the backing layer comprises a proximal wound-facing face and a distal face and is configured to be placed over a wound; a wound filler comprising a polyurethane foam configured to be placed under the backing layer and over the wound; at least one inlet passage for moving fluid to the wound, wherein the at least one inlet passage is in fluid communication with an opening in the backing layer; at least one outlet passage for moving fluid away from the wound, wherein the at least one outlet passage is in fluid communication with an opening in the backing layer; a wound dressing pressure sensor for detecting negative pressure at the wound; a fluid reservoir containing an anti-bacterial fluid in fluid communication with the at least one inlet passage to supply anti-bacterial fluid from the fluid reservoir to the wound; a vacuum pump configured to move fluid through at least the opening in the backing layer and the outlet passage; and a pressure feedback regulator, wherein the pressure feedback regulator is configured to receive an output signal from the wound dressing pressure sensor and control the vacuum pump to produce a desired negative pressure at the wound.
