Abstract:
Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed towards wound dressings comprising a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

Claim (Index 29):
An apparatus to provide suction to a wound site comprising:\n a wound dressing comprising:\n an absorbent layer for absorbing wound exudate from the wound site, and \n a cover layer overlying the absorbent layer and comprising an opening; \n a fluidic connector attached to the wound dressing comprising:\n a spacer layer comprising a proximal end, an elongate middle portion, and a distal end, wherein the proximal end of the spacer layer includes an opening; \n a top layer constructed from a liquid impermeable material provided over the spacer layer, the top layer comprising a proximal end, an elongate middle portion, and a distal end; \n a bottom layer constructed from a liquid impermeable material provided below the spacer layer, the bottom layer comprising a proximal end, an elongate middle portion, and a distal end, wherein the top layer and the bottom layer are sealed together around a perimeter thereof to substantially enclose the spacer layer; \n one or more apertures in the bottom layer beneath the distal end of the spacer layer, wherein the distal end of the bottom layer of the fluidic connector is positioned over the cover layer of the wound dressing with the one or more apertures in the bottom layer being positioned over the opening in the cover layer; and \n a conduit comprising a proximal end and a distal end, wherein the distal end of the conduit is in fluid communication with the proximal end of the spacer layer, and wherein a length of the conduit at the distal end of the conduit extends through the opening of the proximal end of the spacer layer and rests between portions of the spacer layer at the proximal end; and \n a filter positioned below the distal end of the spacer layer adjacent the one or more apertures; wherein the filter is adhered to the distal end of the bottom layer, wherein the filter is positioned to substantially prevent the wound exudate from escaping the wound dressing through the opening in the cover layer.
