Plasma applicator

Abstract

A plasma applicator comprising an electrotechnical core for generating a cold atmospheric pressure or low-pressure plasma for the treatment of human and/or animal and/or technical surfaces, wherein the electrotechnical core has a side facing the surface to be treated and a side facing away from the surface to be treated and comprises the following layers, arranged above one another, starting from the side facing the surface to be treated, a first insulation layer, a first electrode structure which is provided with a first contact for establishing electrical contact between the first electrode structure and a power supply unit and which is grounded during operation, a second insulation layer, which is embodied to galvanically isolate the first electrode structure and a second electrode structure from one another, a second electrode structure which is provided with a second contact for establishing electrical contact between the second electrode structure and a power supply unit and which is driven during operation by a voltage signal that is supplied by a power supply unit and that is sufficient to ignite a plasma, a third insulation layer, which is embodied to galvanically isolate the second electrode structure and a third electrode structure from one another, and a third electrode structure which is provided with a third contact in order to ground the third electrode structure during operation, the plasma applicator further comprising an enclosure, wherein the plasma applicator is affixed to a bag, said bag being configured to enclose a body or body segment and to thus form a sealed gas space around the body or body segment.
