Cold high frequency-excited plasma beam producing device for e.g. medical purpose, has high frequency generator, resonance coil, insulating body and high-voltage electrode arranged in housing so that components are circulated by process gas

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

This invention describes a device that produces a cold plasma beam using high-frequency electrical excitation. The device is built into a metal housing and contains a high-frequency generator, a resonance coil, an insulating body (which also acts as a gas nozzle), and a high-voltage electrode. These components are arranged so that a process gas flows through them, resulting in the formation of a cold plasma beam at the exit. The setup is particularly suited for applications requiring safe, localized plasma treatment, even on heat-sensitive materials or tissues.

Patent Abstract

The device has a metal housing (7) functioning as a grounded electrode (2) in a region of an emergent plasma (1). A high frequency (HF) generator (8), a HF resonance coil (5), an insulating body (4) and a high-voltage electrode (3) are arranged in the housing in such a manner that the generator, the coil, the body and the high-voltage electrode are permeated or circulated by a process gas (6). The resonance coil has a closed ferrite core suitable for the high frequency. The insulating body functions as a gas nozzle, and the high-voltage electrode is mounted in the insulating body.
