Abstract
An apparatus for cleansing wounds, in which wound exudate is removed from a wound bed and selectively cleansed and returned to the wound. The cleansing means removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The associated wound dressing and cleansing means are conformable to the wound, and may have irrigant fluid circulated from a reservoir by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing.

11. A wound dressing apparatus, which comprises:
-
a wound dressing including a backing layer for positioning over a wound area; and
a negative pressure system comprising;
a miniature pump for applying negative pressure to the wound dressing to move wound exudate from the wound area, the miniature pump being integral with the dressing; and
a pressure control device configured to control or vary the pressure under the backing layer applied by the pump in response to a pressure detected underneath the backing layer. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A wound dressing apparatus, comprising:
-
a wound dressing including an absorbent member positionable relative to a wound area, the absorbent member being disposed underneath a backing layer; and
a negative pressure system mounted on the wound dressing, the negative pressure system including;
a miniature pump for applying negative pressure to the wound area to facilitate removal of wound exudate from the wound area, the portable pump being integral with the wound dressing, a pressure control device configured to control or vary the pressure under the backing layer applied by the pump in response to a pressure detected underneath the backing layer. - View Dependent Claims (25)

26. An apparatus for the treatment of a wound, comprising:
-
a backing layer configured to be positioned over at least a portion of the wound;
a porous layer configured to be positioned between the wound and the backing layer to define a space beneath the backing layer and an upper surface of the porous layer;
a filter configured to retain wound exudate in the space between the porous layer and the backing layer; and
,a vacuum source for applying vacuum to the wound to draw wound exudate into the space between the porous layer and the backing layer. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A method of treating a wound comprising:
-
positioning a wound dressing over the wound, the wound dressing comprising;
a backing layer;
a porous layer beneath the backing layer;
a resiliently-flexible filler located in a space between the backing layer and the porous layer; and
a filter configured to retain wound exudate in the space between the backing layer and the porous layer;
sealing the wound dressing over the wound; and
applying negative pressure to the wound dressing to draw wound exudate into the space between the backing layer and the porous layer. - View Dependent Claims (39)
