Problems solved by technology

[0003] Traditionally, atmospheric pressure plasma is not suitable for sterilizing the surface of sensitive objects, especially for the surface of human skin, due to the large size of the power supply required, the price is relatively high, and the temperature of the generated plasma is high. Sterilization, thereby limiting the application in skin surface disinfection and treatment of dermatological diseases

Abstract

The invention discloses a novel plasma pen, comprising a power supply, a gas-supply source, and a novel plasma pen main body; the characteristics are as follows: the novel plasma pen main body comprises one or a plurality of insulation medium tubes, the inside and the outside of the insulation medium tube are respectively provided with an electrode which is connected with a RF (radio frequency) or a high frequency power supply, the outside of a plasma micro-beam flow is provided with a shell body, one side of the shell body is provided with one or a plurality of nozzles, the other side is provided with an air-inflow connecting port, a gas flow control valve switch and a power supply switch; when the gas in the gas-supply source flows through the clearance between the electrode inside the insulation medium tube and the electrode outside the insulation medium tube, the breakdown ionization forms the plasma to spray out of the shell body, and the sprayed plasma beam flow can be used for cleaning, disinfecting and sterilizing various surfaces.

Description

【Technical field】 [0001] The present invention relates to a new type of plasma pen, especially one that is excited by a high-frequency or radio frequency power supply. Metal electrodes are respectively arranged inside and outside one or more insulating medium tubes, and the inert gas flows through the insulating medium. A device that is broken down and ionized between the inner and outer electrodes of the tube to form a plasma microbeam that is ejected out of the shell. 【Background technique】 [0002] Atmospheric pressure plasma technology is a new technology that has been developed rapidly in recent years and has been widely used. It can be applied to: (1) surface cleaning (such as cleaning surface biochemical pollution, surface organic pollution). (2) Modification of the material surface. (3) Surface disinfection and sterilization, etc. [0003] Traditionally, atmospheric pressure plasma is not suitable for sterilizing the surface of sensitive objects, especially for the...
