Description
Technical field
This utility model relates to a kind of transferring cabin with sterilizing function, mainly is applicable to pharmacy, experimental facilities field.
Background technology
Should reduce as far as possible by the risk of microgranule or microbial contamination when material enters A/B level district in the existing aseptic medicine production process.At present the method that adopts is that material is handled and the sealed container of packing under the protection of A level mostly, with disinfectant container is carried out surperficial wiping sterilization then, and puts into that air-lock (or pass-through box) wind that is attached thereto drenches, UV enters A/B level district after irradiation a period of time.There is certain risk in this manually-operated: if not thorough to package sterilization, material is delivered to A level district and tears interior bag open, may bring the risk of microbiological contamination to the operation in A level district.
Point out in the 7th in appendix 1 aseptic medicine among 2010 editions GMP: reduce product or handled material as far as possible by the risk of microgranule or microbial contamination.This has proposed great challenge to transmission technology traditional in the existing manufacturing technique flow process.Therefore, be badly in need of a kind of transfer device that has sterilizing function and replace traditional air-lock (or pass-through box).
What generally use in the transfer device that has the hydrogen peroxide function in the prior art is a kind of hydrogen peroxide plasma sterilizer, disclose a kind of pass-through box hydrogen peroxide plasma decontamination system such as Chinese utility model patent 200920031195.0, similarly the scheme of device employing is earlier transferring cabin to be carried out vacuum pumping, after having guaranteed vacuum certain in the transferring cabin, inject hydrogenperoxide steam generator, behind overflash, transmit, cover the material surface, material to be transferred is carried out bio-decontaminated, the high-voltage pulse that utilizes pulsed high voltage generator to produce at last is added on the electrode of plasma reactor, between the plasma reaction electrode, produce highfield, effect by highfield finally forms the hydrogen peroxide of gas ions with the ionization of part hydrogen peroxide molecule, collaboratively thus carries out the bio-decontaminated function and eliminates residuals.Yet, adopt similar method that material is shifted and bio-decontaminated also exists certain defective: on the one hand, some material that has packing may cause breakage because of the not anti-negative pressure of packaging bag through behind the evacuation, or makes hydrogen peroxide penetrate packing material and contaminated material; On the other hand, the whole system cost is higher, and equipment is installed complicated, safeguards and gets up to have certain degree of difficulty.
In addition, Chinese patent application 201110267800.6 discloses a kind of transferring cabin that has the hydrogen peroxide sterilizing function, partly constituted by transferring cabin cabin body, ventilating system, sterilization cycle air return system, PTC auxiliary heating system, filtration system, atmospheric control, electrical apparatus control system, hydrogen peroxide sterilization generator etc., this utility model is claimed, solved the existing Bacterial cross problem that thoroughly do not cause because of the material sterilization in the process that material shifts of carrying out between the clean zone of difference, it has sterilization back noresidue, free of contamination beneficial effect.But also there is following problem in this utility model: 1, hydrogen peroxide can not get effective decomposition after sterilization, has certain residually, and can the material after the sterilization be exerted an influence.2, transferring cabin cabin body can form certain negative pressure or malleation when air intake and air-out, and material package is exerted an influence.Even penetrate the bales stained material.3, external air inlet and gas outlet from blower fan away from, link to each other by the longer pipe road, increased the chance of polluting, also can produce turbulent flow, be unfavorable for the stable of cabin internal pressure.4, troublesome poeration, entire equipment complexity, cost height.
