Abstract
A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.
Claims13
A method of delivering reduced pressure to a wound, the method comprising:
- disposing a super-absorbent dressing bolster adjacent a patient's epidermis and over the wound, the super-absorbent dressing bolster comprising:
- an entry layer having a first surface and a second, inward-facing surface,
- a super-absorbent layer having a first surface and second surface, the second, inward-facing surface of the super-absorbent layer disposed adjacent to the first surface of the entry layer,
- a top layer having a first surface and a second, inward-facing surface, the second, inward-facing surface of the top layer disposed adjacent to the first surface of the super-absorbent layer, wherein the top layer is a non-breathable layer, and
- a drape extending over the first surface of the top layer of the dressing bolster;
- fluidly coupling a reduced-pressure source to the super-absorbent dressing bolster;
- and
- delivering reduced pressure to the super-absorbent dressing bolster.
