Wound cleansing apparatus in-situ

An apparatus for treating a wound, which comprises:

• a wound dressing member positionable over a wound, the wound dressing member including a permeable film adapted for positioning in contact with the wound and a filler, the wound dressing member comprising a unidirectional flow structure configured to be located between the wound and filler, the unidirectional flow structure configured to permit fluid to flow in only one direction from the wound through the permeable film to sequester wound exudate in the filler;
• and
• a negative pressure mechanism including a pump configured to generate negative pressure and to supply the negative pressure to the wound.

A method for facilitating healing of a wound, comprising the steps of:

• positioning a wound dressing over a wound by at least partially enclosing the wound with a backing layer of the wound dressing, wherein a pump configured to move fluid is mounted relative to the wound dressing and the pump is located beneath the backing layer;
• and actuating the pump to move fluid relative to the wound to facilitate healing of the wound.
