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 treating a wound, comprising: a wound dressing comprising: a backing layer having a proximal, wound-facing side and a distal side;a boss mounted to the backing layer at an opening in the backing layer and protruding distally therefrom;a porous material having a proximal, wound-fa
1. An apparatus for treating a wound, comprising: a wound dressing comprising: a backing layer having a proximal, wound-facing side and a distal side;a boss mounted to the backing layer at an opening in the backing layer and protruding distally therefrom;a porous material having a proximal, wound-facing side and a distal side, the porous material provided on the proximal side of the backing layer;an adhesive on a periphery of the backing layer, wherein the adhesive is configured to attach the backing layer to skin around the wound; anda membrane provided on the proximal, wound-facing side of the porous material, the membrane comprising a plurality of apertures configured to contact the wound, wherein the porous material is configured to be in fluid communication with the membrane; anda first manifold provided on the proximal, wound-facing side of the porous material, wherein the first manifold is configured to be in communication with a distal side of the membrane;a fluid offtake tube configured to be mounted to the boss and provide fluid communication between a negative pressure source and the wound dressing. 2. The apparatus of claim 1, wherein the porous material is attached to the backing layer. 3. The apparatus of claim 1, wherein the proximal, wound-facing side of the backing layer is capable of forming a substantially fluid-tight seal over the wound and the distal side is configured to be exposed to atmospheric pressure. 4. The apparatus of claim 1, wherein the membrane and the porous material are configured to be simultaneously removed from the wound together with the backing layer. 5. The apparatus of claim 1, further comprising the negative pressure source configured to apply negative pressure to the wound dressing. 6. The apparatus of claim 1, further comprising a controller configured to adjust negative pressure applied by the negative pressure source. 7. The apparatus of claim 1, further comprising a second manifold provided on the distal side of the porous material and the proximal, wound-facing side of the backing layer, wherein the second manifold is configured to be in communication with the fluid offtake tube. 8. The apparatus of claim 1, wherein the boss is positioned on the proximal, wound-facing side of the backing layer. 9. The apparatus of claim 1, wherein the porous material comprises foam. 10. An apparatus for treating a wound, comprising: a wound dressing comprising: a backing layer having a proximal, wound-facing side and a distal side;a reinforcement mounted to the backing layer at an opening in the backing layer and protruding distally therefrom;a porous material having a proximal, wound-facing side and a distal side, the porous material provided on the proximal side of the backing layer;an adhesive on a periphery of the backing layer, wherein the adhesive is configured to attach the backing layer to skin around the wound;a first membrane provided on the proximal, wound-facing side of the porous material, the first membrane comprising a plurality of apertures configured to contact the wound, wherein the porous material is configured to be in fluid communication with the first membrane; anda second membrane provided on the distal side of the porous material and on the proximal, wound-facing side of the backing layer, the second membrane comprising a plurality of apertures, wherein the porous material is configured to be in fluid communication with the second membrane; anda fluid offtake tube configured to extend through the reinforcement and provide fluid communication between the wound dressing and a negative pressure source. 11. The apparatus of claim 10, further comprising a vacuum pump configured to apply negative pressure to the wound dressing. 12. The apparatus of claim 11, further comprising a controller configured to adjust negative pressure applied by the vacuum pump. 13. The apparatus of claim 10, further comprising a collection container configured to be in fluid communication with the dressing. 14. The apparatus of claim 10, wherein the proximal, wound-facing side of the backing layer is capable of forming a substantially fluid-tight seal over the wound and the distal side is configured to be exposed to atmospheric pressure. 15. The apparatus of claim 10, wherein the first membrane and the porous material are configured to be simultaneously removed from the wound together with the backing layer. 16. The apparatus of claim 10, wherein the second membrane is configured to be in communication with the fluid offtake tube. 17. The apparatus of claim 10, wherein the reinforcement is positioned on the proximal, wound-facing side of the backing layer. 18. The apparatus of claim 10, wherein the porous material comprises foam.
