Abstract
A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises 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.

1-134. (canceled)
A wound dressing, comprising:
- a gas impermeable cover layer comprising a fluid passage;
- an absorbent layer configured to absorb wound exudate, the absorbent layer comprising a through hole positioned beneath the fluid passage;
- and
- a transmission layer positioned beneath the absorbent layer, the transmission layer comprising a first surface and a second surface, the transmission layer comprising a plurality of spacer elements having lateral stiffness and extending perpendicularly between the first surface and the second surface, the lateral stiffness of the spacer elements configured to dissipate force operating over a first area on the first surface to a second area on the second surface.
1 more element
A wound treatment apparatus, comprising:
- a vacuum pump configured to deliver negative pressure;
- a gas impermeable cover layer comprising a fluid passage;
- a suction port configured to connect to the vacuum pump, the suction port positioned above the fluid passage;
- an absorbent layer configured to absorb wound exudate;
- and
- a transmission layer positioned beneath the absorbent layer, the transmission layer comprising a first surface and a second surface, the transmission layer comprising a plurality of spacer elements having lateral stiffness and extending perpendicularly between the first surface and the second surface, the lateral stiffness of the spacer elements configured to dissipate force operating over a first area on the first surface to a second area on the second surface.
3 more elements
A wound dressing, comprising:
- a gas impermeable cover layer;
- and
- a transmission layer positioned below the cover layer, the transmission layer comprising a first surface and a second surface, the first surface comprising a first fabric layer and the second surface comprising a second fabric layer, wherein a filament count of the first fabric layer is greater than a filament count of the second fabric layer.
