  • Patent number: 10039849
    Abstract: 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.

  • Patent number: 9855355
    Abstract: An essential feature of the invention is the original combination of a plasma process and a sealing system. This is achieved with external tubes (4, 6), which are connected to each other so as to be impermeable to gas, but galvanically insulated, and of which at least one is electrically conductive, such that the external tubes form an antechamber between the two external tubes (4, 6) and a treatment chamber between the external tube (6) and the internal tube (1).

  • Publication number: 20160008500
    Abstract: The present invention relates to a device for plasma-treating hollow bodies, such as bottles, vials, syringes, shut-off caps, etc., in particular with a view to sterilising said hollow bodies, and is equally suitable for various discharge types such as dielectric barrier discharge and discharges with high frequency and microwave excitation. The device allows a pressure gradient to be set between the interior and the exterior of the object to be treated, which can be advantageously used for process control and plasma formation and forms the basis for an optimised in-line method of plasma-treatment of hollow bodies. An essential feature of the invention is the original combination of a plasma process and a sealing system.

  • Patent number: 8541065
    Abstract: The invention relates to a method for coating surfaces with micro- and nanoparticles, the micro- and nanoparticles being chemically bonded to the surface, comprising the steps of pre-treatment of the surface with a plasma method, simultaneous or subsequent application of the micro- and nanoparticles to the surface, and subsequent fixation of the micro and nanoparticles on the surface using a plasma method, characterized in that the fixation of the micro- and nanoparticles takes place with the aid of anisothermal plasmas, the median electrical energy of which lies in the range of the bond dissociation energy of the micro- and nanoparticles, thus allowing the strength of the chemical bond between the surface and the micro- and nanoparticles to be variably set.

  • Patent number: 8232728
    Abstract: The invention relates to a method for igniting and generating an expanding diffuse microwave plasma and to a device for carrying out such a method. The method is particularly suited for generating microwave plasmas for the purpose of carrying out plasma treatment of surfaces and substances, particularly three-dimensional objects as well as particles under atmospheric pressure. The aim of the invention is to provide a method for igniting and generating these plasmas that is, particularly under normal and high pressure, easy and operationally safe as well as, in principle, carried out without a flow of gas. The invention also relates to a method and device for carrying out plasma treatment of surfaces and substances by means of such a plasma, which makes an effective plasma treatment possible due to its high stability with regard to plasma generation and maintenance, low gas consumption and a high plasma volume.
