Description
[technical field]
The present invention relates to a kind of novel cold plasma discharge instrument, espespecially in a hand-held housing, be provided with the insulated dielectric tube of a medium-high frequency high voltage power supply and end sealing, when human body skin, when coming close to or in contact with jacketed electrode, produce the instrument of cold plasma.
[background technology]
The generation of plasma is generally between two electrodes, the breakdown ionization of the gas between electrode and form plasma.Plasma is that contain a large amount of electronics, ion and free radical external becomes the electroneutral gas that is ionized, due to unique physical and the chemical property that plasma possesses, therefore can utilize plasma to realize the effects such as sterilizing on modification, surface clean, grafting new material and surface to body surface.Test also verified: utilize plasma discharge kill bacteria fast, when in discharge power relatively hour (such as being less than 20 watt-hours), the temperature of plasma is very low, can with the contact skin of human body, and can not cause burn to skin.Such as: normal-pressure radio-frequency helium plasma line, the normal pressure high-frequency dielectric stops the helium plasma jet, or the argon plasma line etc., these plasma lines have the pathogenic bacteria of well killing skin surface and the effect of microorganism, therefore, cold plasma line equipment can be for to treating for skin disease, the sterilizing of wound etc.But the plasma beam flow device that at present institute is generally used, be all this more expensive working gas of employing helium, and this makes plasma line generation systems structure numerous and diverse, and use cost is very high; The atmospheric plasma of other type, human body skin can not directly contact, and discharge temp is high, the generation ozone concentration is large etc.
How in the situation that do not use external auxiliary noble gas to produce cold plasma, the direct ionization air forms the air cold plasma, thereby saves cost and the simplified apparatus cost that uses noble gas.In order to realize this purpose, the present invention adopts a kind of novel cold plasma discharge instrument, adopt the single electrode Dielectric Disruptive Discharge, when human body skin approaches (being less than 2mm) or touch the electrode with dielectric, human body is as a suspension electrode, just produce the electric discharge of air cold plasma between the dielectric material of human body skin and jacketed electrode, this cold plasma can play the skin surface sterilization functions, and when human body skin during away from jacketed electrode (being greater than 2mm), plasma discharge just can disappear automatically.
