Device for Generating Cold Atmospheric Plasma

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a flexible device for generating cold atmospheric plasma at atmospheric pressure, designed for application directly on human or animal skin or tissues. The device consists of a multilayer stack that can conform to curved or irregular surfaces and produces a controlled, large-area plasma discharge for medical use. The system includes special electrode structures and dielectric layers to safely generate plasma, and also comprises a dedicated cable and generator for safe, user-friendly high-voltage supply.

Patent Abstract

The invention relates to a device for generating a cold atmospheric pressure plasma for treating human and/or animal surfaces, comprising a flat flexible multilayer system with a face which faces the surface to be treated and a face which faces away from the surface to be treated. The multilayer system comprises the following layers: namely a first electrode layer on the multilayer system face facing away from the surface to be treated, a second electrode layer on the multilayer system face facing the surface to be treated, said electrode layer having a plurality of recesses or being designed in a grid-like or meandering manner, a dielectricum layer which is arranged between the first electrode layer and the second electrode layer, and a spacer layer which is arranged adjacently to the second electrode layer on the multilayer system face facing the surface to be treated. The invention further relates to a cable, a generator unit for providing a high voltage, and a system.
