Abstract
A hydrogen peroxide filling system for the plasma sterilizer is composed of supporting frame, liquid storage tank, evaporator with nozzle, delivering pipeline between said liquid storage tank, and the high-precision metering pump with step motor, which is installed to said delivering pipeline.
Description
Technical field
The present invention relates to a kind of hydrogen peroxide filling system of plasma sterilization device, be used for to plasma sterilization device filling hydrogen peroxide.
Background technology
Sterilization is the important step of diseases prevention and control, 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.
In above-mentioned low-temperature plasma sterilization system, be used for supplying the employing card casket system that the device of hydrogen peroxide has, it holds a certain amount of hydrogenperoxide steam generator.The hydrogenperoxide steam generator that is contained in wherein is transported to solution conveyor tube by a syringe pump, and by vaporizer the liquid hydroperoxide solution of sending into is vaporized, and sends into the sterilization chamber then, but this system is very complicated and expensive.The employing Level Detection technology that has is in addition controlled the liquid capacity of injection, and shortcoming is that degree of accuracy is relatively poor.
Hydrogen peroxide gas is injected in the sterile chamber, so that diffuse and penetrate into the sterilization body surface.The concentration of hydrogen peroxide is generally 0.05 to the 10mg/ litre, when hydrogen peroxide is injected under suitable concentration, can will add reaction chamber such as oxygen, nitrogen, argon or similar assist gas.Therefore, if apply optimum capacity, the optimum efficiency that can obtain to sterilize.Because only about 2mL, so require the injection of hydrogen peroxide to want accurately, minimum degree of accuracy will be at 0.05mL for each capacity that injects.Accurately adding is not easy very much.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, cheap, degree of accuracy height, hydrogen peroxide filling system of plasma sterilization device easy to utilize.
Hydrogen peroxide filling system of plasma sterilization device of the present invention, comprise support, reserving liquid tank, carburator and transfer pipeline, reserving liquid tank and carburator are communicated with by transfer pipeline, be connected with gas tip on the carburator, it is characterized in that being connected with on the transfer pipeline high-precision measuring pump, cooperate dosing pump that motor is installed.
The present invention is simple in structure, and is cheap, easy to utilize, and supplies by the high-precision measuring pump, the degree of accuracy height.
Semiconductor cooler is established in bottom at reserving liquid tank, makes hydrogen peroxide be in lower temperature environment, guarantees the self performance of hydrogen peroxide on the one hand, avoids the volatilization of the hydrogen peroxide that oxidisability is strong, volatility is big on the other hand, and the protection environment is safe and reliable.
Carburettor design is electric heating carburetor, and is simple in structure, realizes control automatically easily.
On reserving liquid tank, set up corresponding Packaging Bottle and puncture device, make things convenient for the interpolation of hydrogen peroxide.
Establish the control electromagnetic valve between carburator and gas tip, be beneficial to and realize control automatically, carburator preferably includes two-stage, and electromagnetic valve is located on the connecting line between the two-stage carburator, connects gas tip on the carburator of the second level.In carburator, establish thermodetector,, cooperate temperature relay that temperature is controlled among the hydrogen peroxide liquid vapourizing temperature as thermocouple etc.
In reserving liquid tank, be fitted with level probe, be convenient to monitor the hydrogen peroxide liquid surplus, in time remind the user to add hydrogen peroxide liquid to avoid the sterilization failure.
Among the present invention, carburator, level probe, high-precision measuring pump, motor and semiconductor cooler etc. all have the commercially available prod, directly buy to use to get final product.The adapted automaton can be realized automatic filling.
The present invention can automatically supply with the sterile chamber with few fixed amount hydrogenperoxide steam generator.After hydrogenperoxide steam generator at first is full of reserving liquid tank, semiconductor cooler can make reserving liquid tank constant within certain temperature to reduce or to reduce the volatilization of hydrogen peroxide liquid, level probe monitoring hydrogen peroxide liquid surplus in time reminds the user to add hydrogen peroxide liquid to avoid the sterilization failure.When need injecting hydrogen peroxide, the step pitch of coming the control step motor by stepping motor control circuit, and then the control hydrogen peroxide enters into the capacity of dosing pump, because the dosing pump precision can reach 1 μ L, thereby realizes accurately supply.Like this, thus what and precision of liquid supply rate promptly depend on the precision of step motor control.After above-mentioned action is finished, again the liquid in the dosing pump is injected into heating vaporization in the one-level vaporization tube, the cooperation temperature relay is controlled at temperature among the hydrogen peroxide liquid vapourizing temperature, again by controlling the opening and closing of electromagnetic valve, hydrogen peroxide gas is delivered to the secondary vaporization tube by transfer pipeline, and vaporizing once more is diffused as the preparation that plasmaization is carried out gas after gas tip enters in the sterile chamber.
Hydrogen peroxide filling system of plasma sterilization device of the present invention, simple in structure, cheap, and the liquid of minute quantity accurately can be supplied with the sterile chamber, and the degree of accuracy height, easy to utilize.
