surface modification

Portable plasma treatment system (1) for generating an anisothermal plasma for use on humans, comprising the components: a) a pressurized gas cylinder (10) with a valve (11), the pressurized gas cylinder (10) having a useful volume of at most five liters, b ) a hand-held device (20) with a plasma nozzle (21), the hand-held device (20) being set up and provided to generate the anisothermal plasma, c) a control unit (30) set up to take one from the pressurized gas cylinder (20 ) to regulate the flowing gas stream and / or an electrode voltage in the hand-held device (20) so that the plasma ca

A device for generating plasma (1) comprises a high voltage electrode (10) as well as at least one external electrode (11, 12), wherein the high voltage electrode (10) at least in one coordinate direction (34) is arranged between conductive material of at least one external electrode (11, 12). The high voltage electrode (10) is covered with a dielectric (21) at least one side facing an external electrode (11, 12).

A plasma treatment device having an electrode arrangement (3) for generating a plasma in a supplied gas stream. The electrode arrangement has at least one movably mounted electrode. The plasma is preferably a cold atmospheric pressure plasma and can be generated so as to vary in location by means of movement of the at least one electrode.

The invention relates to a medical device comprising a biocompatible material having an exposed surface prone to biofilm growth. The biocompatible material comprises a doping of an antibacterial metal compound. A concentration of the doping compound ranges from 1% to 30% (w/w) within an outer layer adjacent to the exposed surface, and is essentially zero within a bulk layer of the biocompatible material.

The invention relates to 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.
