Assembly for the treatment of wounds
An assembly for the treatment of wounds comprising a device for generating a plasma, or an excited gas or gas mixture, respectively. A covering is used to cover a wound area. A first conduit connects the device and the covering and a second conduit connects the covering and a pump. The device is arranged within a housing comprising an opening. The device comprises a piezoelectric transformer having a high-voltage end for generating the plasma, and is arranged within the housing such that the high-voltage end is directed towards the opening. The plasma or the excited gas or gas mixture, respectively, is generated in a region of the opening of the housing. A wound cover comprising a means for guiding the plasma across the wound area is arranged between the covering and the wound area.
