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 heal
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.
1. A multi-component wound dressing for treating a wound using a reduced pressure, comprising: a wound covering element adapted to be applied to a surface of the skin to cover the wound, thereby forming a wound space, said wound covering element having at least one connector configured to connect to
1. A multi-component wound dressing for treating a wound using a reduced pressure, comprising: a wound covering element adapted to be applied to a surface of the skin to cover the wound, thereby forming a wound space, said wound covering element having at least one connector configured to connect to a pressure reducing device and through which reduced pressure can be applied to the wound;a sorption unit configured to absorb wound exudate material in the wound space;a porous member positioned above the sorption unit in a fluid pathway between the sorption unit and the pressure reducing the porous member configured to prevent passage of wound exudate material from the sorption unit into the at least one connector;wherein the wound dressing is configured such that absorbed wound exudate material, when sequestered by the sorption unit, remains in the wound space until the sorption unit is removed; anda wound contact layer positioned below the sorption unit. 2. The multi-component dressing of claim 1, further comprising a pressure reducing device connected to the at least one connector. 3. The multi-component dressing of claim 2, further comprising at least one pipe connected to the pressure reducing device. 4. The multi-component dressing of claim 3, wherein the pipe connects to the pressure reducing device through an opening passing through the wound covering element. 5. The multi-component dressing of claim 3, wherein the pipe connects to a boss mounted to the wound covering element at an opening in the wound covering element. 6. The multi-component dressing of claim 2, wherein the pressure reducing device comprises a pump. 7. The multi-component dressing of claim 2, wherein the pump is mounted to the wound covering element. 8. The multi-component dressing of claim 2, wherein the pump is separate from the multi-component dressing. 9. The multi-component dressing of claim 2, wherein the pump is operated by a piezoelectric transducer. 10. The multi-component dressing of claim 1, wherein the dressing has at least one conformable hollow body that contains the sorption unit. 11. The multi-component dressing of claim 10, wherein the conformable hollow body is defined by a membrane which has pores. 12. The multi-component dressing of claim 11, wherein the conformable hollow body has an inflatable and deflatable balloon core. 13. The multi-component dressing of claim 10, wherein a material of the conformable hollow body contains an active substance which has a therapeutic effect on a wound healing process. 14. The multi-component dressing of claim 10, wherein the conformable hollow body is glued to the wound covering element, a periphery being left free at the wound covering element. 15. The multi-component dressing of claim 1, wherein the sorption unit comprises a gel. 16. The multi-component dressing of claim 15, wherein the gel is hydrophilic. 17. The multi-component dressing of claim 15, wherein the gel is cross-linked. 18. The multi-component dressing of claim 15, wherein the gel is a cellulosic gel. 19.
