Abstract
A wound therapy device is disclosed. The wound therapy device may include a housing for covering at least a portion of a wound and for sealing to a body surface of a patient. The housing may also include a liquid collector for retaining liquid therein and a vacuum connection for coupling to a vacuum source. The vacuum connection may be in gaseous communication with the liquid collector. The vacuum connection may be separated from the liquid collector by a liquid barrier.

-58. (canceled)
A reduced-pressure system for treating a tissue site, comprising:
- a first dressing component comprising a super-absorbent material;
- a second dressing component comprising a silicone material;
- a wound cover for providing a fluid seal over the first and second dressing components;
- a reduced-pressure interface coupled to the wound cover;
- and
- a reduced-pressure delivery conduit for fluidly coupling to the reduced-pressure interface.
A wound therapy device, comprising:
- a dressing, comprising:
- a first dressing component comprising an absorbent material;
- a second dressing component comprising a structural support;
- a wound cover for providing a fluid seal over the first and second dressing components;
- a wound interface layer disposed beneath the absorbent layer, the wound interface layer comprising a porous material configured to allow wound fluid to pass through.
A wound therapy device, comprising:
- a dressing, comprising:
- a disperser layer;
- a wound cover for providing a fluid seal over the disperser layer;
- and
- a wound interface layer disposed beneath the disperser layer, the wound interface layer comprising a porous material configured to allow wound fluid to pass through;
- wherein the disperser layer, wound cover, and wound interface layer are sized to be positioned over the wound area and over intact skin adjacent to the wound area at least partially enclosing the wound area;
- and
- a reduced-pressure delivery conduit for fluidly coupling to the dressing and configured to deliver reduced pressure to the dressing such that reduced pressure is transmitted through the disperser layer to the wound area and to the intact skin adjacent to the wound area.
