Claims21
-50. (canceled)
A wound dressing comprising:
- an acquisition distribution layer configured to horizontally wick fluid as the fluid is absorbed upward through the wound dressing;
- an absorbent layer over the acquisition distribution layer;
- a backing layer above the absorbent layer;
- and
- a fluid connector configured to connect the backing layer to a source of negative pressure.
The wound dressing of claim 60, wherein the transmission layer is configured to vertically wick fluid.
The wound dressing of claim 62, wherein a majority of the filaments, by volume, extend vertically.
A wound dressing comprising:
- an acquisition distribution layer comprising a plurality of fibers, wherein a majority of the fibers, by volume, extend horizontally;
- a wound contact layer below the acquisition distribution layer;
- a transmission layer between the wound contact layer and the acquisition distribution layer, wherein transmission layer comprises a plurality of filaments, wherein the majority of the filaments, by volume, extend vertically;
- an absorbent layer over the acquisition distribution layer;
- and
- a backing layer above the absorbent layer.
