Publication number: 20240050760Abstract: The invention relates to a system (1) for generating and controlling a non-thermal atmospheric pressure plasma, comprising: —a discharge space (10) into which a working gas can be introduced via a first opening (12), wherein a plasma (5) can be generated in the discharge space (10), wherein the discharge space (10) has a second opening (14), so that the plasma (5, 6) can exit from the discharge space (10) through this second opening (14) and —at least one high-voltage electrode (20) for generating an electromagnetic field for generating a plasma (5) in the discharge space (10). The plasma (5, 6) exiting through the second opening (14) is controlled by a throughflow controller (40) of the system (1), which throughflow controller (40) is designed to adjust a volume flow (60) of the working gas through the first opening (12) from a working gas source (50) into the discharge space (10).Type: ApplicationFiled: October 5, 2020Publication date: February 15, 2024Applicant: LEIBNIZ-INSTITUT FÜR PLASMAFORSCHUNG UND TECHNOLOGIE E.V.Inventors: Rayk KOHLS, Klaus-Dieter WELTMANN, Philipp TURSKI, Norbert LEMBKE, Torsten GERLING, Laura VILARDELL SCHOLTEN, Stefan HORN

Patent number: 8994271Abstract: 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.Type: GrantFiled: July 31, 2010Date of Patent: March 31, 2015Assignee: Leibniz—Institut fuer Plasmaforschung und Technologie E.

Patent number: 8557187Abstract: 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.Type: GrantFiled: February 12, 2010Date of Patent: October 15, 2013Assignee: Neoplas GmbHInventors: Joerg Ehlbeck, Ruediger Foest, Eckhard Kindel, Norbert Lembke, Manfred Stieber, Klaus-Dieter Weltmann

Publication number: 20130026137Abstract: The invention relates to a device and a method for generating a pulsed (intermittent), cold, atmospheric pressure plasma, preferably a thread, for precise antimicrobial plasma treatment (antisepsis, disinfection, sterilization, decontamination) of very small surfaces and cavities, including on living human and animal bodies, preferably in the field of medicine, by means of a negative direct-current corona discharge, the device comprising at least one electrode for generating high field strengths, through or around which electrode the gas to be ionized flows in a gas channel, wherein the electrically conductive structure (surface, cavity) to be treated is used as the counter-electrode. Said plasma can also be used in general for cleaning, coating, activating, and etching surfaces.Type: ApplicationFiled: November 27, 2010Publication date: January 31, 2013Applicant: Leibniz-Institut fuer Plasmaforschung und Technologie e.V.Inventors: Eckhard Kindel, Klaus-Dieter Weltmann, Norbert Lembke, Thomas Kocher
