  • Patent number: 9192040
    Abstract: A device and method for generating a physical plasma in hoses of long and simultaneously constricted lumen, flexible or rigid dielectric hoses, tubes or other hollow bodies in the low, normal or overpressure range, which are partially or completely filled or flushed by process medium of gas or gas mixtures, one or more liquids, liquids including gas bubbles, liquid-gas mixtures, aerosols and/or foam, for purposes of cleaning, activating, coating, modifying and biologically decontaminating, disinfecting, sterilizing the inner walls of the hoses or the process medium itself. The device includes a high voltage supply and a process medium supply, at least one electrically conductive grounded electrode and at least one electrically conductive high voltage electrode, both embedded in the wall of the hose.

  • Patent number: 8994271
    Abstract: A device for generating a cold, HF-excited plasma under atmospheric pressure conditions can be used advantageously for plasma treatment of materials for cosmetic and medical purposes. The device contains a metal housing functioning as a grounded electrode in the region of the emergent plasma, wherein an HF generator, an HF resonance coil having a closed ferrite core suitable for the high frequency, an insulating body acting as a gas nozzle, and a high-voltage electrode mounted in the insulating body are disposed in such a manner that they are permeated or circulated around by process gas. By integrating the plasma nozzle and required control electronics in a miniaturized handheld device, or by using a short high-voltage cable, the invention allows compliance with the electromagnetic compatibility directives and allows the power loss to be minimized and thus a mobile application to be implemented.

  • Publication number: 20150088234
    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.

  • Patent number: 8557187
    Abstract: A method and a series of devices for dry cleaning, activating, modifying, coating, and biologically decontaminating (degerming, disinfecting, sterilizing) surfaces by means of an atmospheric pressure plasma generated using a surface barrier discharge are provided. The invention is used for dry cleaning, activating, coating, modifying, and biologically contaminating surfaces by means of an atmospheric pressure plasma generated in a defined, flowing gas atmosphere by a surface barrier discharge, comprising a high-voltage electrode that is covered with a dielectric or ferroelectric material, an electrically conducting grounded contact electrode, a high-voltage supply, a gas supply, and a gas nozzle (encompassing a gas outlet); said gas nozzle is located in the direct vicinity of the grounded contact electrode, is integrated into the contact electrode, or acts as the grounded contact electrode.
