The present invention relates to a device for generating a dielectric barrier discharge for treatment of an object to be activated with non-thermal atmospheric pressure plasma, comprising a dielectric working chamber which has a wall of a dielectric material and which encloses a working space, wherein a metallization is applied to an outer side of the wall facing away from the working space, wherein the working space is an open volume, and a high-voltage source which is configured to apply a high voltage to the metallization or to the object to be activated when the object to be activated is in the working space. According to a further aspect, the invention relates to a method of treatment of an object to be activated with a non-thermal atmospheric pressure plasma.

Device for generating a dielectric barrier discharge and method for treating an object to be activated

In an embodiment a device includes a first housing in which a piezoelectric transformer is arranged and a second housing in which a control circuit is arranged, the control circuit configured to apply an input voltage to the piezoelectric transformer, wherein the piezoelectric transformer is configured to ionize a process medium, and wherein the device is configured to provide a circulating air operation so that the process medium is guided from the piezoelectric transformer through a catalytic converter and then back to the piezoelectric transformer and generate a non-thermal atmospheric pressure plasma.

Device for producing a non-thermal atmospheric pressure plasma and active space comprising such a device

A device for producing a non-thermal atmospheric pressure plasma and an active space including such a device are disclosed. In an embodiment a device includes a first housing, in which a piezoelectric transformer is arranged and a second housing, in which a control circuit is arranged, the control circuit configured to apply an input voltage to the piezoelectric transformer, wherein the first housing comprises a coating configured to eradicate irritant gases.

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.

Assembly for treating 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.

Assembly for the treatment of wounds

An apparatus for producing a plasma including a control circuit which is electrically connected to a piezoelectric transformer in order to excite the piezoelectric transformer. A hand-held device that uses the apparatus. The piezoelectric transformer is constructed of several layers. The control circuit is implemented on a circuit board, and the piezoelectric transformer is held over the circuit board by means of a region of a first end. A high voltage is applied to a second free end of the piezoelectric transformer. The plasma is produced at atmospheric pressure.

Apparatus for producing a plasma and hand-held device having the apparatus

Presented is a method for forming at least one structure on a substrate. Utilizing a low-temperature plasma jet, powder, of which the structure shall be constructed, is applied to a surface of the substrate. Using at least one laser beam, heat is input into the substrate and/or the powder within a laser incidence region on the substrate. The heat input delays solidification of the powder particles, which are partly or fully melted in the plasma jet, on the substrate and thereby enables the formation of good adhesion between the applied powder, and thus the structure constructed out of the powder, and the substrate. The invention further relates to an apparatus for performing the method.
