Abstract
The utility model relates to a low-temperature hydrogen peroxide plasma sterilizer, which comprises an inner cavity of the sterilizer. The sterilizer is characterized in that the inner cavity of the sterilizer is internally provided with a radio frequency plasma parallel electrode plate which is supported on an upper support rod and a lower support rod and is connected with a radio frequency electrode by a lead. As the radio frequency plasma parallel electrode plate is independently positioned in the circular or rectangular metal sterilizer and has large area, the ionization rate to hydrogen peroxide gas is high, the contact area with an object to be sterilized is large, the uniformity is good, and the sterilizing and resolution effect is good. The radio frequency plasma parallel electrode plate and a storage rack for placing the object to be sterilized are optimized to be designed into a whole body, thereby not only saving the space, but also improving the sterilizing and resolution effect.
Description
Technical field
This utility model relates to a kind of improved low temperature hydrogen peroxide plasma sterilizer.
Background technology
Sterilization is the important step of health care diseases prevention, also is the important component part of implementing the policy of putting prevention first.Particularly in infectious disease control, sterilization has become one of key means that cuts off the route of transmission.Since nineteen sixty-eight Menashi uses argon plasma to kill the vial surface bacteria first, utilized ionized gas---the sterilizing technology of plasma just constantly substitutes routine techniques, is widely used in industry-by-industry, and shows huge advantage.
The plasma sterilization technology is the new physical sterilization technology that the Disinfection field occurs in recent years.Along with medical science and biological development of high-tech, existing sterilization technology can not satisfy some special requirement, and the accurate Medical Instruments of some non-refractories all needs the low temperature sterilization technology as fiber sight glass and other fear hot material.The plasma sterilization technology is after sterilization technologies such as methane, oxirane, glutaraldehyde, another new low temperature sterilization technology.The plasma sterilization technology has overcome long, virose characteristics of said method time, has increased new medical apparatus and instruments low temperature sterilization method.
Plasma is meant constantly and applies energy and make it be dissociated into the state of matter of yin, yang charge particle from the outside to material.Because according to the energy level order, that state of matter is followed successively by is solid-state, liquid, gaseous state, plasma, so plasma is called the 4th attitude traditionally again.Except that being present in nature, plasma also can obtain by manual type.Normally gas is applied electric field, charged particle is quickened.Because ion is heavier, so what be accelerated all is electronics.By electronics with cause ionization than heavy particle collision, finally form plasma.
Low temperature plasma sterilizing technology almost possessed a kind of desirable sterilizing method the full terms that should possess: compare with high pressure steam sterilization, dry heat sterilization, sterilization time is short; With ethylidene oxygen is that the chemosterilization of main body is compared, and operative temperature is low; Can be widely used in the sterilization of multiple material and article; Particularly after cutting off the electricity supply, the various active particles of generation can disappear in several milliseconds, so need not to ventilate, can not constitute injury to operator, and are safe and reliable; Thereby applied widely.
The utility model content
The purpose of this utility model is to provide a kind of low temperature hydrogen peroxide plasma sterilizer, can make gas ionization more abundant, and plasma distribution is more even, and sterilization effect is better.
Low temperature hydrogen peroxide plasma sterilizer described in the utility model, the steriliser inner chamber is arranged, it is characterized in that being provided with the radio frequency plasma parallel electrode plate in the steriliser inner chamber, parallel electrode plate is supported on the upper and lower support bar, and parallel electrode plate is connected on the radio-frequency electrode by lead.
The physical dimension of support bar can with the volumetrical size of steriliser and discharge power by the sterilization spatial volume be not less than 5 milliwatts/centimetre
3Basic parameter, increase or reduce the quantity of battery lead plate.To satisfy the sterilization requirement of low temperature hydrogen peroxide plasma sterilizer.
Parallel electrode plate is designed to two one group, the 2-4 group can be set in the steriliser inner chamber.
Parallel electrode plate is designed to place cell structure form by sterilizing article, one-object-many-purposes.
The parallel electrode plate rustproof aluminium sheet is made, and makes full use of the sterilization effect that the good heat conductivity of aluminum promotes the low temperature hydrogen peroxide plasma sterilizer, and the oblong aperture that distributes on the plate body is so that gas flow.Rustproof aluminium sheet thickness selects 2mm, and the wide 12mm of can be of oblong aperture, length can be 68mm etc., and is comparatively suitable.
Under the coarse vacuum situation, a spot of hydrogen peroxide gas is put into steriliser main body internal diffusion, on two electrodes, add radio-frequency voltage simultaneously, gas produces ionization and forms plasma, implements effective sterilizing to putting into the intravital article of steriliser master.The plasma line of the low temperature that can under coarse vacuum, produce, area stable discharge by the radio frequency low-voltage, thus opened up road widely for plasma technique in the application in fields such as sterilization, sterilization.
Radio frequency plasma parallel electrode plate described in the utility model, available sealing at one end, an end has in the circle or rectangular metal container of door that can sealed vacuum, or two ends all have in the circle or rectangular metal container of door that can sealed vacuum.Shell upper has an air inlet; There is the port of an evacuation at the rear portion; Pressure transmitter is connected with canister; Be equipped with between hydrogen peroxide gas loading system and the canister and be connected by valve; Between vacuum pump and the canister vacuum valve is housed, is connected by pipeline.This parallel electrode plate well is connected by radio-frequency electrode with radio-frequency power supply, forms discharge range between this parallel pole.Under the coarse vacuum situation below 100 handkerchiefs, on two electrodes, add 50-250 volt radio-frequency voltage, discharge power by the sterilization spatial volume be not less than 5 milliwatts/centimetre
3, rf frequency is that 13.56MHz produces ionization and forms plasma, this plasma can be implemented sterilization to putting into the intravital article of steriliser master.And to being decomposed by the micro-residual peroxide on the sterilization thing.
Radio frequency plasma parallel electrode plate described in the utility model is securely fixed in the steriliser main body, guarantee between the parallel electrode plate, and the steriliser main body between insulation.
In this utility model, can be according to instructions for use and technology general knowledge, the adjustment that increases some corresponding adnexaes and suit is to improve serviceability.
The utlity model has following advantage:
Because the radio frequency plasma parallel electrode plate independently is arranged in circle or rectangular metal steriliser, the pole plate area is big, to the ionization rate height of hydrogen peroxide gas, big with the sterilized object contact area, good uniformity, sterilization, resolve effective.Radio frequency plasma parallel electrode plate and the shelf optimal design of placing sterilized object are formed in one, have both saved the space, can improve sterilization effect again and resolve effect.
