The present invention relates to the field of electrotherapy and measuring by means of electric cur-rents for diagnostic purposes, and more particularly to an electrode arrangement for facilitating wound healing, a method for measuring wound healing and a wound dressing having an electrode arrangement. A wound dressing according is described which includes at least two impedance reference electrodes, a frame like counter-electrode and stimulation electrodes in a form of an array; and a bioadhesive affinity layer surrounding the stimulation electrodes; said wound dressing being suited for applying on top of the wound so that the stimulation electrode array is on the wound area, and that the at least two impedance reference electrodes and the frame like counter-electrode are suited for placing in contact with the healthy skin surrounding the wound area; which electrodes, are suited for applying LIDC type electrical stimulation current to the wound area and for bioimpedance measurement.

Arrangement for facilitating wound healing, a method for measuring wound healing and a wound dressing

A wound dressing according to the present invention comprises at least two impedance reference electrodes, a frame like counter-electrode and stimulation electrodes in a form of an array; and a bioadhesive affinity layer surrounding the stimulation electrodes; said wound dressing being suited for applying on top of the wound so that the stimulation electrode array is on the wound area, and that the at least two impedance reference electrodes and the frame like counter-electrode are suited for placing in contact with the healthy skin surrounding the wound area; which electrodes, are suited for applying LIDC type electrical stimulation current to the wound area and for bioimpedance measurement. The wound dressing according to the present invention provide a continuous, non-invasive and objective solution for monitoring chronic wound healing without disturbing the delicate healing process.

The use of i) finely divided knotwood, or ii) an extract, obtained by extracting knotwood with a polar solvent and recovering the extract, as an antioxidative agent. A fraction of the extract may also be used as an antioxidative agent.
