ASSEMBLY FOR TREATING WOUNDS

摘要

The invention relates to an assembly for treating wounds and to a hand held unit for treating wounds. The assembly and the hand held unit comprise a device for producing a plasma and/or an excited gas or gas mixture by means of a piezoelectric transformer, which is housed together with a circuit board in a housing of the device, and the assembly comprises an expansion element. A control circuit, to which the piezoelectric transformer is electrically connected, is realized on the circuit board. A second end of the expansion element surrounds a wound region to be treated. A first end of the expansion element is detachably connected to the housing of the device at the opening of the housing. The produced plasma and/or excited gas or gas mixture thus enters the expansion element from the opening of the housing.

主权项

1. An assembly for treating wounds having a device for generating a plasma and/or an excited gas or gas mixture, wherein the device comprises:
a housing; a piezoelectric transformer arranged in the housing; a circuit board arranged in the housing, with a control circuit, to which the piezoelectric transformer is electrically connected; an opening formed in the housing towards which opening the high voltage end of the piezoelectric transformer is directed, wherein a plasma generated with the device and/or the excited gas or gas mixture, respectively, exits from the opening of the housing; and, an expansion element detachably connected with a first end to the housing of the device at the opening thereof, and with a second end surrounding a wound region to be treated, wherein a cross-sectional area of the second end of the expansion element is larger than a cross-sectional area of the first end of the expansion element.
