SKIN TISSUE IMPROVING DEVICE WHICH IRRADIATES GAS WHICH IS CHANGED INTO PLASMA

PROBLEM TO BE SOLVED: To improve the condition of a skin tissue under various kinds of configurations by a method wherein a gas is fed to a plasma generating part, and changed into a plasma, and is cast on a skin tissue. SOLUTION: From a gas supply source 4, an inert gas such as helium and argon (helium is especially preferable) is fed to a plasma generating part 3 in a casing 2 as a raw material gas. In the plasma generating part 3, an electrode 7 for high frequency discharging, which is connected to a high frequency high voltage power source 6, is provided, and a plasma P is generated in the fed raw material gas. This gas which is changed into a plasma is jetted to the outside from a plasma gas jetting nozzle 8. A counter electrode plate 9 which is connected to the high frequency high voltage power source 6, is fitted on the body surface of a person to be treated, and a high frequency high voltage is applied between the electrode 7 and the counter electrode plate 9. Thus, the gas which flows between both electrodes 7, 9 is changed into a plasma, and the body surface skin tissue between the electrodes 7, 9 the plasma gas is cast, and the condition can be improved.
