The plasma generation device is connected via a pipeline with the capsule body of the germicidal capsule. The utility model can fast and effectively carry the disinfection of instruments under the low temperature and at the same time protect the instruments from being damaged.
Description
Technical field
This utility model relates to a kind of plasma low temperature sterilization device.
Background technology
Along with the application of plasma low temperature sterilization devices such as hydrogen peroxide, the characteristic of its low temperature quick sterilization and the influence of no environment improves hospital's social benefit and economic benefit greatly.But present steriliser product all is that the parts such as high-frequency and high-voltage electrode of ionization chamber and generation plasma are arranged in the sterilization cabin of steriliser, when using this steriliser, the sterilization cabin of placing apparatus subject to sterilization has large-area mesh electrode on every side, can produce high-frequency high-pressure electromagnetic field between this mesh electrode and the sterilization cabin body, bear the limit if this electromagnetic field intensity has surpassed the electromagnetic field of the particularly accurate electronic equipments of apparatus subject to sterilization, may cause the permanent damages of electronic equipments; In addition, if electronic equipments when apparatus is run into high-field electrode, touches the metal part in sterilization cabin owing to place improperly again simultaneously, gently then sterilization can't be carried out, and need reappose apparatus, heavy then permanent damages electronic equipments.
Summary of the invention
The purpose of this utility model is the problem of the fragile electronic equipments that exists at existing plasma sterilizer, and a kind of and plasma low temperature sterilization device that sterilizing efficiency high fool proof for electronic equipments subject to sterilization is provided.
The purpose of this utility model be achieved in that this utility model comprise the sterilization cabin and and device for vacuum generation, described sterilization cabin comprises cabin body and hatch door, be provided with one to several plasma generating devices outside described sterilization cabin, described plasma generating device is connected by the cabin body of pipeline with the sterilization cabin.
Technique effect of the present utility model is:
1, because devices such as the ionization chamber of generation plasma and electrode all are arranged on outside the sterilization cabin, do not have high-frequency and high-voltage electrode parts in the sterilization cabin, whole sterilization space is the equipotentiality body of a ground connection, has protected electronic equipments not to be damaged effectively.
2, owing to plasma generating device is arranged on outside the sterilization cabin, so this utility model can be provided with several plasma generating devices, can make plasma enter the sterilization cabin, more uniform plasma density is provided, thereby guarantee sterilization effect from different angles.
3, this utility model has improved the concentration and the purity of plasmas such as hydrogen peroxide, has strengthened sterilization effect and has shortened sterilization time, has reduced the halfway risk of sterilization.
4, owing to do not have electrode and be used for ionized space in the sterilization cabin, this utility model has improved the volumetrical utilization rate in sterilization cabin.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of this utility model one embodiment.
The specific embodiment
As shown in Figure 1, present embodiment comprises sterilization cabin, device for vacuum generation and a plasma generating device, described sterilization cabin comprises a cabin body 8 and two hatch doors 9, be provided with encapsulant between hatch door 9 and the cabin body 8, guarantee the sealing in sterilization cabin, apparatus subject to sterilization will leave in the sterilization cabin sterilizes; Described device for vacuum generation is made of vacuum pump 12 and two-bit triplet electromagnetic valve 11, couple together by pipeline 10 between the cabin body 8 in vacuum pump 12 and sterilization cabin, two-bit triplet electromagnetic valve 11 is arranged on this pipeline 10, communicates with vacuum pump 12 in the sterilization cabin during evacuation, and device for vacuum generation is used for reducing the pressure in sterilization cabin, form low pressure, the external condition that produces plasma is provided, sterilizes when finishing back recovery atmospheric pressure, sterilization communicates with atmosphere in the cabin, be convenient to open hatch door, take apparatus away; Described plasma generating device is the hydrogen peroxide plasma generator, it is arranged on outside the sterilization cabin, it comprises hydrogen peroxide reserving liquid tank 1 and plasma generator, plasma generator comprises the ionization chamber 6 of sealing, in ionization chamber 6, be provided with two electrodes 4,5, electrode 5 ground connection wherein, two electrodes 4, isolate by insulator between 5, hydrogen peroxide reserving liquid tank 1 is connected by pipeline 3 with ionization chamber 6 and is provided with electromagnetic valve 2 on this pipeline 3, between electromagnetic valve 2 and ionization chamber 6, also be provided with vapourizing unit on this pipeline 3, ionization chamber 6 with the sterilization cabin cabin body 8 between be connected by pipeline 7, hydrogen peroxide reserving liquid tank 1 is used for depositing hydrogenperoxide steam generator, electromagnetic valve 2 is used for controlling the amount of the hydrogenperoxide steam generator that enters ionization chamber 6, ionization chamber 6 is used for ionization by hydrogen peroxide reserving liquid tank 1 and through the hydrogen peroxide gas of overflash, produce hydrogen peroxide plasma, these hydrogen peroxide plasmas enter in the sterilization cabin by pipeline 7, and apparatus is sterilized.
The operation principle of present embodiment is as described below: the user puts into the sterilization cabin on request with apparatus subject to sterilization, shut hatch door 9 ready after, at first device for vacuum generation work, pressure in the sterilization cabin begins to reduce, when pressure reaches low pressure request, start working with the plasma generating device that the sterilization cabin is connected, an amount of hydrogenperoxide steam generator is entered in the ionization chamber 6 of plasma generator by hydrogen peroxide reserving liquid tank 1, the hydrogen peroxide gas is ionized to and is hydrogen peroxide plasma, hydrogen peroxide plasma enters the sterilization cabin by pipeline 7, and the apparatus in the sterilization cabin is sterilized uniformly.Because apparatus is in the cabin body 8 of ground connection and the equipotentiality body that hatch door 9 is formed fully, thereby has well protected electronic medical equipment not damaged by intensive electromagnetism place.After sterilization finished, the pressure that device for vacuum generation will sterilize in the cabin reverted to an atmospheric pressure gradually, at this moment just can open the hatch door 9 in the cabin of sterilizing, and had taken the apparatus of having sterilized away.
This utility model is different according to sterilization volume size in cabin and shape, can be provided with one, two or several plasma generating devices, to guarantee the concentration and the pressure of sterilization cabin endoperoxides hydrogen plasma, when plasma generating device is provided with several, they can be connected from the cabin body of different angles with the sterilization cabin, so that more uniform plasma density to be provided, thereby guarantee the effect of sterilization.
