An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated 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. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) 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 dressing and a method of treatment using the apparatus.
1. An apparatus for treatment of a wound, comprising: a lower porous film comprising a plurality of apertures, the lower porous film adapted to conform to a shape of the wound, wherein the lower porous film comprises a disc-shaped periphery; anda plurality of circumferentially-arranged spaces, each
1. An apparatus for treatment of a wound, comprising: a lower porous film comprising a plurality of apertures, the lower porous film adapted to conform to a shape of the wound, wherein the lower porous film comprises a disc-shaped periphery; anda plurality of circumferentially-arranged spaces, each space defined by the lower porous film and an upper membrane attached to the lower porous film, wherein each space has an outer periphery adjacent the disc-shaped periphery of the lower porous film and opens in a radially-inward direction toward a center portion of the lower film, and wherein the outer peripheries of each of the plurality of circumferentially-arranged spaces are circumferentially spaced apart around the disc-shaped periphery of the lower porous film;wherein the lower porous film is sealed to said upper membrane along at least a portion of the outer peripheries of each of the plurality of the circumferentially-arranged spaces. 2. The apparatus of claim 1, further comprising a backing layer capable of forming a relatively fluid tight seal of closure over the wound. 3. The apparatus of claim 2, further comprising a conduit configured to be in fluid communication with a space under the backing layer. 4. The apparatus of claim 2, further comprising a wound filler positionable beneath the backing layer and above the lower porous film. 5. The apparatus of claim 4, wherein the wound filler is conformable to the shape of the wound. 6. The apparatus of claim 2, further comprising a source of negative pressure configured to provide negative pressure to a space beneath the backing layer. 7. The apparatus of claim 1, wherein each of the outer peripheries of the plurality of circumferentially-arranged spaces has a curved shape. 8. The apparatus of claim 1, wherein each of the outer peripheries of the plurality of circumferentially-arranged are separated by portions comprising only the lower porous film. 9. The apparatus of claim 1, comprising four circumferentially-arranged spaces. 10. The apparatus of claim 1, comprising six circumferentially-arranged spaces. 11. The apparatus of claim 1, comprising eight circumferentially-arranged spaces.
