Description
technical fieldthe present invention relates to a kind of novel simple EO disinfected bag, be applicable to the disinfected parasite killing of daily Common People, the dirty clothing that collect at be particularly useful for doing washing industry and washing center, at the washing sterilization in early stage.EO can kill various microorganisms, comprises bacterial propagule, brood cell, virus and fungal spore, is a kind of broad-spectrum biocide.Be commonly considered as because it can non-specific alkylating occur with protein, DNA and the RNA of microorganism.EO in aqueous solution can with protein on free carboxy (COOH), amino (2NH2), sulfydryl (2SH) and hydroxyl (2OH) generation alkylating, replace labile hydrogen atom and form the compound with hydroxyl second root (CH2CH2OH), group on protein is by alkylation, the reactive group that protein has been lost need in analytic metabolism, hinder the normal chemical reaction of bacterioprotein and metabolism, thereby caused microbial death.Up to the present, all data show that EO bactericidal action is irreversible, that is to say that EO is antibacterial (sterileagent) rather than disinfectant (disinfectant).And show that according to various clinical, scientific research results EO is the best a kind of chemosterilant of sterilization effect in all chemosterilants or biocide.Oxirane can suppress the activity of some microbial enzymes, comprises phosphoric acid kinase, peptidase, choline enzyme and cholinesterase.Oxirane also causes the deactivation of microorganism with DNA, RNA generation alkylating.Eo sterilization, is one of the most effective gaseous sterilization method in the world, is the indispensable and first-selected sterilizing methods of hospital.At present, in the hospital of the U.S., Japan, China, adopt all kinds of article of eo sterilization as follows: 1. endoscope's class: laryngoscope, bronchoscope, esophagoscope, cystoscope and urethroscope, mediastinoscope, thoracoscope, esophagus fibrescope, fibergastroscope, duodenal scope, colonofiberscope, fiberbronchoscope, blood vessel fibrescope etc.2. plastics, rubber: glove, fingerstall, syringe, syringe, hemostix, infusion set, transfusion set, adopt urinal, experiment tube, ventricular catheter, venous duct, vessel catheter, cardiac catheter, hose, catheter, sponge kind, liner class.3. apparatus equipment class operating room automatic suturing machine, stitching thread, sewing needle, artificial esophagus, artificial bone, artificial heart distinguish film, artificial blood vessel, hot fluorine opinion (politef) artificial membrane, artificial lung loop, cardiac pacemaker, pacemaker electrode, drainage system, postoperative suction device, lumbar puncture device, o urethral catheterization device, intraperitoneal dialysis circuit, critesistor clinical thermometer, stethoscope, medical electric drill, medical electric saw, electric knife, battery, hone lamella, photographing unit etc.4. anaesthetize vessel class trachea inner flexible tube, nose flexible pipe, flexible pipe, suction hose, face shield, corrugated tube, bag, closed circulation loop, artificial respiration's parts, aerosol apparatus, oxygen account etc. for anesthesia for anesthesia for tracheotomy.5. cotton fine goods its other: medicated clothing clothing, gauze, binder, cotton balls, swab stick, absorbent cotton, towel, woollen blanket, operating coat, operating cap, brush, bedding, pillowcase, mattress, bed pad, books, toy etc.Although oxirane has sterilizing purposes so widely, while using due to its three large itself drawbacks limit the convenience of its use: (1) whole sterilization cycle time is longer, and its reason is that to need the long period to ventilate to remove EO residual.(2) EO is poisonous, is suspicious carcinogen, and the concentration that must control EO in room air is lower than state specified standards.(3) EO is inflammable and explosive, when storage and sterilizing, definitely can not reveal.Safe steriliser be must select, safety operation and storage carried out.The present invention relates to a kind of novel simple EO disinfected bag, overcome above deficiency, the more convenience-for-people property of sterilizing methods, randomness, the safety that make.
background technologythe method for disinfection and sterilization that at present laundry industry is generally used has that ozone, ultraviolet and liquid are chloride, three kinds of peroxide detergent sterilizations, but each mode all exists certain drawback.Ozone can make medicated clothing decolouring, bactericidal effect limitation, effectively kill virus; Ultraviolet penetration capacity is poor, and sterilization is not thorough; And liquid disinfectant has certain corrosiveness to medicated clothing, after using, the liquid of discharge also may cause environmental pollution.Medicated clothing liquid disinfectant comparison of brands domestic on Vehicles Collected from Market is few, mainly take sanitary purpose washing as main, and general bactericidal activity is poor, and one time the larger cost of injected volume is high.On Vehicles Collected from Market, medicated clothing sterile products is to be mainly abroad main brand, this class disinfectant mainly adopts chlorocresol compounds as disinfection main constituent, and in long-term use procedure, find larger to people's skin irritation, this compounds is also larger to corrosion of metal simultaneously, and metalware and environment are had to impact in various degree; By a large amount of research and investigation, find, the bactericidal activity of above-mentioned clothes disinfector exists fungicidal spectrum actual use amount narrow, that sterilization needs larger, the problem that cost is high, so this compounds is the kind being eliminated gradually.The detergent with sterilizing growing up recent years mostly is oxidation dosage form, as oxygen floats, chlorine-containing agent etc., and the unstable easy decomposition of its character, bactericidal activity reduces; Strong oxidizer can cause washed fabric decolouring as Dexol, SODIUM PERCARBONATE soak in addition, thereby affects its scope of application etc.Novel simple EO disinfected bag, the mode of employing low temperature EO gas fumigation, has overcome the various drawbacks that clothes sterilizes under the modes such as ozone, ultraviolet, liquid disinfectant.Maximum advantage has 9 points: (1) can be used for non-refractory, the not sterilizing of moisture-proof article.(2) oxirane is considered to the best chemosterilant of a kind of sterilization effect, can kill all microorganisms and comprise bacterial spore.(3) penetrance is strong, can be in order to the sterilizing at the penetrating position of various difficulties: as some more carefully, longer conduit is difficult to reach sterilization effect by other low temperature sterilization methods, and can only be with EO or irradiation.(4) little to article damage, because EO killing microorganisms is to utilize alkylation principle but not oxidizing process, therefore, very little to article damage, thermo-labile precision instrument sterilizing is had to purposes very widely.(5), during sterilizing, can be convenient to store with various lappings parcels, transportation, open parcel and can use the danger of having avoided cross-contamination.(6) there are chemistry, the biological monitoring means of standard, thereby can effectively control sterilization quality, find in time the parcel of sterilizing failure.(7) ethylene oxide residue after sterilizing is discharged into and in water, generates nontoxic ethylene glycol, environmentally safe.(8) carry out sterilizing before utilizing epoxyethane gas for disinfection to wash medicated clothing, reduced simultaneously and used a large amount of disinfectant, environmentally safe, makes the first operation of washing reach sterilizing environmental protection.(9) easy to use, walk away safety.By all dirty linens, after classifying packing, pack in novel simple EO disinfected bag, through putting medicine, prick bag mouth, break ampere into pieces to carry out low temperature stifling, acts on after four to six hours, medicated clothing is thoroughly sterilizing just.Do not need special instrument and equipment, as long as dress bag just can penetrate the clothes fibers such as micropore linsey-woolsey, spot is thoroughly peeled off.Before washing, carry out thorough sterilizing, cut off the pathogen contamination source of medicated clothing before washing completely.Make in washing with washing after medicated clothing and technique, be aseptic flow process, really reach health environment-friendly laundry.
