1-50. (canceled)
A negative pressure wound treatment system comprising:
- a source of negative pressure;
- a negative pressure wound dressing, comprising:
- a wound contact layer,
- a fluid transmitting layer overlying the wound contact layer, the fluid transmitting layer configured to vertically wick fluid and comprising a top fabric layer, a bottom fabric layer and a plurality of filaments extending perpendicularly between the top fabric layer and the bottom fabric layer, a majority of the filaments extending downward from the top fabric layer or upward from the bottom fabric layer,
- a fluid distributing layer overlying the fluid transmitting layer, the fluid distributing layer comprising a mix of cellulosic fibers and composite fibers, the fluid distributing layer configured to horizontally wick fluid as the fluid is absorbed upward through the negative pressure wound dressing, the fluid distributing layer comprising a plurality of fibers, individual fibers comprising a polyethylene terephthalate core and a polyethylene outer layer, a majority of the fiber volume extending horizontally,
- an absorbent layer overlying the fluid distributing layer, and
- a backing layer above the absorbent layer;
- and
- a fluidic connector configured to connect the backing layer to a source of negative pressure.
