Thin equipment microgap sterilizing, more particularly to a kind of Low-temperature Plasma Sterilization pen.
Background technology
When material is provided continuously with energy, its temperature can rise, and generally then turn from solid-state to liquid to gaseous state
Become.Persistently providing energy causes system to undergo further state transformation, and during this, gas neutral atom or molecule are by energy
Amount collision is opened, and generates negatron, positive or negative conductance ion and other excited species.It is above-mentioned by it is powered and other by
The molecular mixture of sharp grain, it is shown that joint conduction, the 4th state referred to as " plasma ", also referred to as material.
The generation of plasma be usually between two electrodes, the breakdown ionization of gas between electrode and formed etc. from
Daughter, plasma is that external containing substantial amounts of electronics, ion and free radical is ionized gas into electroneutral, due to wait from
Unique physical and chemical property that daughter possesses, therefore modification to body surface, table can be realized using plasma
The effects such as sterilizing of face cleaning, grafting new material and surface.Experiment is also verified：Can be quick using plasma discharge
Bacterium is killed, when comparing smaller in discharge power, the temperature of plasma is very low, can be contacted with the skin of human body, without
Burn can be caused to skin, seamless sterilizing can also be carried out to some fine equipment.Such as：Normal-pressure radio-frequency helium plasma
Body line, normal pressure high-frequency dielectric stops helium plasma jet, or argon plasma line etc., and these plasma lines have
The effect of the germ and microorganism of skin surface is killed well, and therefore, cold plasma line equipment can be used for skin
The treatment of disease, the sterilizing of wound etc., wherein, cure mechanism is：Utilize the gaseous free radicals, band having in low temperature plasma
It is lethal that charged particle, ultraviolet etc. carry out collision to microbial pathogens from molecular level, it is to avoid the side effect that medicine often triggers,
And no matter bacterial antibiotic can all kill either with or without drug resistance, " the five of plasma can be escaped from even without bacterium without exception
Refer to mountain ".
Such as Chinese patent（The patent No.：2008801230075）, it discloses a kind of plasma body sterilizing equipment, including：
