Patent number: 10039849Abstract: The invention relates to a method and to a device for quickly decontaminating and sterilizing preferably thermolabile goods using a plasma gas that is preferably generated from air as a process gas, with the subsequent humidification of said plasma gas with water. The method comprises the following steps: generating a plasma from air as the process gas, which forms reactive nitrogen and oxygen species; oxidizing NO to form NO2 at temperatures below 400° C. so that a plasma-activated gas mixture forms having an NO2 content of at least 0.3%; bringing said plasma-activated gas mixture in contact with water in one or more of the states of aggregation thereof; bringing the latter gas mixture in contact with the objects to be decontaminated or sterilized.Type: GrantFiled: April 14, 2017Date of Patent: August 7, 2018Assignee: LEIBNIZ-INSTITUT FUER PLASMAFORSCHUNG UND TECHNOLOGIE E. V., INP GREIFSWALDInventors: Udo Krohmann, Joerg Ehlbeck, Torsten Neumann, Uta Schnabel, Mathias Andrasch, Wolfram Lehmann, Klaus-Dieter Weltmann

Patent number: 9192040Abstract: 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.Type: GrantFiled: January 26, 2011Date of Patent: November 17, 2015Assignees: Leibniz-Institut fuer Plasmaforschung und Technologie E.V., INP Greifswald, Xion GmbHInventors: Joerg Ehlbeck, Klaus-Dieter Weltmann, Manfred Stieber, Joern Winter, Kim Winterweber
