Claims6
A wound dressing comprising:
- an acquisition distribution layer;
- an absorbent layer over the acquisition distribution layer;
- a material layer positioned over the absorbent layer to at least partially visually mask fluid absorbed by the absorbent layer;
- a backing layer above the material layer;
- a fluidic connector coupled to the backing layer, the fluidic connector configured to connect the backing layer to a source of negative pressure;
- and
- a visual indicator positioned beneath the fluidic connector and contiguous with the fluidic connector when the wound dressing is under negative pressure, wherein the visual indicator enables visibility of fluid absorbed beneath the fluidic connector from above the fluidic connector;
- wherein the acquisition distribution layer is configured to horizontally wick the fluid as the fluid is absorbed upward through the wound dressing.
