In order to make available a wound dressing (100) with at least one energy transfer agent (11, 12) and a wound dressing (13), namely a combination of wound dressing and electrode for the stimulation treatment, with which an uniform electrostimulation of the wound can be achieved so that the wound he
In order to make available a wound dressing (100) with at least one energy transfer agent (11, 12) and a wound dressing (13), namely a combination of wound dressing and electrode for the stimulation treatment, with which an uniform electrostimulation of the wound can be achieved so that the wound healing process is considerably improved, it is proposed that the energy transfer agent has at least two layers and that the energy transfer agent (11, 12) has at least two adjacent layers (11, 12), a first layer (11)—energy supply—and a second energy—distribution of energy—(12), whereby the first layer (11) has a lower electric resistance and the second layer (12) a higher electric resistance.

The invention claimed is: 1. A wound dressing, comprising: an electrical energy transfer medium comprising an electrode for electrostimulation of a wound, said electrode having multiple adjacent layers, including a first layer having a first electric resistance and adapted to provide an energy supply with a generally homogenous current distribution across a total area of the energy transfer medium and a second layer for distribution of energy, wherein the second layer has a higher second electric resistance than the first layer; a protection/fixing layer disposed on a side of the first layer generally opposite to the second layer; and a wound pad on a side of the second layer generally opposite the first layer and adapted for direct contact with the wound, wherein the wound pad is electrically conductive, heat conducting or heat generating when energy is applied thereto. 2. A wound dressing according to claim 1, wherein the first layer comprises a silver. 3. A wound dressing according to claim 1, wherein the wound pad is hydrophilic. 4. A wound dressing according to claim 1, wherein the wound pad is electrically conductive. 5. A wound dressing according to claim 1, wherein the wound pad has adhesive properties. 6. A wound dressing according to claim 1, wherein the wound pad is a hydrogel, hydrocolloid, alginate or a polyurethane foam. 7. A wound dressing according to claim 1, wherein the wound pad includes a wound healing promoting substance. 8. A wound dressing according to claim 7, characterized in that the wound healing promoting substance is a growth factor. 9. A wound dressing according to claim 7, wherein the wound substance comprises an antibiotic, antiseptic, vitamin, or an analgesic. 10. A wound dressing according to any of claims 1, 2-4 or 7-9, characterized in that the first and second layers comprise a metal foil or an electrically conductive plastic, rubber, silicone or synthetic material. 11. A wound dressing according to any of claims 1, 2-4 or 7-9, characterized in that the energy transfer medium includes an electrical connecting means which can be connected with an energy producer. 12. A wound dressing according to any of claims 1, 2-4 or 7-9, characterized in that the connecting means is placed on the first layer. 13. A wound dressing according to any of claims 1, 2-4 or 7-9, characterized in that the connecting means is placed on the first and second layer. 14. A wound dressing according to claim 1, characterized in that the protection/fixation layer is configured with an opening. 15. A wound dressing according to claim 1, characterized in that the protection/fixation layer is made of self-adhesive water vapour permeable material. 16. A wound dressing according to claim 1, characterized in that the wound pad has an additional layer on the side opposite to the second layer. 17. A wound dressing according to claim 16, characterized in that the additional layer is a peelable foil. 18. A wound dressing according to claim 17, characterized in that the foil is made of polyethylene, polypropylene or polyurethane. 19. A wound dressing according to either of claims 17 or 18, characterized in that the foil is impermeable to water and active substances. 20. A wound dressing according to claim 1, characterized in that the wound pad has self-adhesive properties. 21. A wound dressing according to any of claims 1, 2-4 or 7-9, characterized in that the wound dressing is flexible and elastic.
