Plasma Generating Device, Plasma Generating System and Method of Generating Plasma

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

This patent discloses a plasma generating device especially suited for antimicrobial treatment of moist surfaces, such as wounds. The device features a high voltage electrode covered by a dielectric layer and arranged between at least one grounded external electrode. Special gas-permeable spacer elements ensure a consistent gap and electrical insulation between the electrodes, allowing for stable plasma generation even in high humidity environments. The architecture also significantly reduces electromagnetic interference, making it suitable for medical applications.

Patent Abstract

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). Between the respective external electrode (11, 12) and the high voltage electrode (10) over its longitudinal extension at least one spacer element (20) is present, which at least in the region of its arrangement electrically insulates the respective external electrode (11,12) from the high voltage electrode (10) and which positions the respective external electrode (11, 12) at a constant distance from the high voltage electrode (10), wherein the spacer element is a gas-permeable foil.
