  • Patent number: 11478292
    Abstract: The invention relates to a device for producing a cold atmospheric pressure plasma for the treatment of human and/or animal surfaces, comprising a flexible, planar multilayer system with a side facing the surface to be treated and a side facing away from the surface to be treated, wherein the multilayer system comprises the following layers, namely a first electrode layer on the facing away side of the multilayer system, second electrode layer on the facing side of the multilayer system, wherein the electrode layer has a plurality of recesses or is formed in a grid-like or meander-shaped fashion, a dielectric layer arranged between the first electrode layer and the second electrode layer, and a spacer layer arranged adjacent the second electrode layer on the facing side of the multilayer system. In addition, the invention relates to a cable, a generator unit for providing a high voltage, and a system.

  • Patent number: 10363429
    Abstract: The invention relates to a device for the treatment of free-form areas and zones of human or animal skin areas or plant surfaces by means of cold atmospheric-pressure plasma. The core of the device is a specific, preferably gas-permeable, electrode arrangement for generating a dielectrically impeded surface discharge where the earthed electrode is composed of electrically conductive textile material and the high-voltage electrode consists of a thin wire or electrically conductive thread which is sheathed with an insulting layer which has to meet specific requirements. On the basis of the present invention, it is possible to generate, in the area of diseased skin parts of the human body, in direct proximity to the skin surface or to wounds, a flat plasma for the treatment of the diseased areas which is acceptable in respect of the stress on the skin caused by temperature and electric potentials.

  • Publication number: 20170216614
    Abstract: Disclosed is a device (1) for biologically decontaminating percutaneous accesses or the stomata of patients, by means of a plasma generator (4) for generating a decontaminating plasma adjacently to a treatment surface (3) of the plasma generator (4). In order to at least partially surround a percutaneous access or stomata, the treatment surface (3) is curved to be adaptable and can be placed against the percutaneous access or stoma.
