A kind of steam chest

Technical field

A kind of sterilizing equipment decontaminating apparatus is the utility model is related to, more particularly to a kind of high-efficiency steam chlorination equipment.

Background technology

Hospital infection serious threat patient safety, huge economic loss is caused to patient, hospital and society.Hospital infection Referent includes patient, family members, medical worker, logistic personnel etc..Hospital infection route of transmission include diagnosis and treatment apparatus, The hand of medical worker, the article of patient's surrounding environment, secretion, excretion and the metabolite of carrier.Hospital infection can root It is divided into autogenous infection and exogenous infection according to the source difference of pathogen.Autogenous infection refers to that patient's body immunity is low Under, itself normal flora caused infection, exogenous infection under the stimulation of endogenous environment refer to by other in external environment Infected caused by the pathogenic microorganism invasion and attack that people brings.The pathogen wide material sources of hospital infection, most epidemic links are in doctor In institute's environment, Long Term Contact antibiotic, there is drug resistance, patient will bring huge difficulty once being infected to treatment.Hospital Infection be pathogen exist between easy receptor and local environment, propagate, reproductive process, pathogen can be colonized extensively In medical environment and survive a period of time, therefore cleaning, sterilization and the monitoring to medical environment are extremely important.Create good Hospital environment health, prevent and reduce the pollution of hospital environment, carry out routine and terminal disinfection and handle, be advantageous to patient disease Recover, improve Level of Hospital Management.Three key elements of hospital infection are the infection sources, route of transmission and Susceptible population, hospital infection Route of transmission have contact transmission, iatrogenic, water source or food pollution, vector, air borne etc., most common of which is Contact transmission.

Hospital is the place that patient concentrates, and pathogenic microorganism is more, and toxicity and propagated strong, and cross-infection easily occurs. Between 3%~17%, the nosocomial infection incidence in China is about the incidence of disease between various countries and area for hospital infection 9.7%, Britain 7.5%, Japan is 5.8%, the U.S. 5.0%, and Belgium is 10.3%.The season distribution of hospital infection is not Together, there is scholar to report that winter-spring season lower respiratory illness patient's nosocomial infection incidence is higher, and have the patient of operative incision in the summer Season, nosocomial infection incidence was higher.CICU is the severely afflicated area of hospital infection, because conditions of patients is critical, invasive behaviour Make it is more, and need it is a large amount of use antibacterials, patient immune function is low.In hospital infection age distribution, You Renbao The age V-shaped distribution of road infected patient, the old man of infant of the age less than 2 years old and age more than 60 years old is susceptible Crowd.It is perfect that main cause is that the immune system of infant is not developed also, and the hypoimmunity of the elderly, basic diseases are heavier, So this two classes crowd is easily infected.

Contact transmission includes direct contact infection and indirect contact transmission, and wherein indirect contact transmission is the master of hospital infection Want circulation way.Document report it is most be medical worker's hand contamination contact transmission, next to that iatrogenic infection, also has been reported that production Woman, which carries disease germs, is broadcast to baby, and patient shares the routes of transmission such as clothing.Communication media is entirely being propagated during hospital infection contact transmission During play vital effect, take precautions against one of important measures of hospital infection be turned off propagate way, cut-out propagate way Footpath should set about from studying and intervening communication media.Indirect contact transmission medium is a lot, including the hand of medical worker, bed basket, prison Instrument, clinical thermometer, phone, calling set etc. are protected, due to complicated, cleaning-sterilizing is difficult for fractional object surface such as keyboard, mouse etc., Easily turn into the medium of contact transmission, cause hospital infection.

Current《Hospital disinfection sanitary standard》In provided for surface disinfection mode, indoor article such as bedside cupboard, Desk, chair etc. use wet-cleaning without requirement under obvious pollution condition, are substantially polluted if having, it is necessary to using hygroscopic material decontamination Clean and sterilize again afterwards.For infection risk, high section office include：Conduit room, clean ward, delivery room, Surgery（Room）, organ Transplant ward, bone-marrow transplantation ward, newborn room, haemodialysis ward, CICU, the department of stomatology, Burn Ward, urgency Examine, clinical laboratory, the body surface in the ward such as infectious disease section, it is desirable to keep dry cleansing, carry out disinfection processing daily, if occurring Need to remove dirt at any time and give sterilization during obvious pollution, thimerosal can use effective chlorine containing 400mg/L-700mg/L Thimerosal wiped, act on 30min, or use the thimerosal containing quaternary ammonium salt, concentration 1000mg/L- 2000mg/L carries out cleaning disinfection.This provides the selection from thimerosal species, the concentration requirement of thimerosal and sterilization frequency etc. Aspect is all relatively more general, and it is suitable for the relatively regular conventional item sterilization in warm case, bed basket one kind surface.It is for example defeated for charging equipment Liquid pump, patient monitor etc., Cavity in Critical Patients use is clinically only limitted to, placement location is relatively fixed, and can typically accomplish " four One " i.e.：One people one one is sterilized with one, as long as implementing the related request for having got well sterilization specification, it becomes possible to be effectively prevented from such Object turns into pathogenic bacteria carrier.The powered hardware devices such as the keyboard of hospital information system, mouse, it is characterized in that surface imperfection, Gap is more, easily shelters evil people and countenance evil practices,《Hospital disinfection sanitary standard》In for this kind of equipment surface without clearly careful disinfection way, Selection regulation, the clinics such as sterilization opportunity, sterilization apparatus easily ignore its sterilization, and they are very likely as the important of hospital infection Communication media.

Medical act at present enters the information age, and medical information refers to medical services digitlization, networking, automatic Change, it includes modern network technology, computer science and database technology, and medical information is by patient information in hospital and hospital Between and hospital internal all departments between share and propagate, including extraction patient data, managing patient information, collect processing shadow As picture and shared data is preserved, while meets the functional requirement of all authorized users.Medical system informationization is united according to the world One standard includes three aspect contents：Hospital Management Informatization, IT application in medical clinics and sanitarian informationization.With doctor The popularization of institute's System information, hospital extensively using computer system, at present in medical system special computer for special use it is few in number, Most or more people share a computer, and hand frequently contacts keyboard, it is possible to germ be present in patient and medical worker Between by computer keyboard, this intermediary is propagated, and computer key panel surface is because its structure is special, surface seam Gap is more, it is uneven, be charging member, easy contamination hides dirt, the easy growth and breeding of bacterium, and be inconvenient to clean with sterilizing, if operating Personnel do not pay attention to hand hygiene before keyboard is contacted, and disinfectant measure execution is not strict, or the unsuitable disinfection way of selection, keyboard Just become very important communication media in nosocomialtion.

For information equipment surface sterilization, clinically thimerosal it is more using the thimerosal of effective chlorine containing 500mg/L or 75% alcohol carries out surface wipes sterilization.It is that the cleaning worker lacked by relevant knowledge performs because the sterilization of such object is most of, The clean condition of disinfector, thimerosal dilution ratio, rag be stained with sterilization liquid measure number, wiping effect whether meet correlation It is required that the problems such as all compared with Customers ' Legal Right.For these problems, there are some new sterile products in the market, as containing quaternary amine Pasteurization towelette disposably is used, is sterilized for Pangquangou Natural Reserve.This research compares the different sterilization sides of surface of keyboard based on clinic The implementation result of method, explore the most effective feasible disinfection way of lesion keyboard, it is desirable to by studying special construction charged object table The sterilization method in face, based on this, the foundation for the sterilization strategy for extending to whole charging equipment body surface that fans out from point to area, with Reach and reduce hospital infection, reduce the purpose of Hospital medical cost.

The disinfection way of the current medical appliance in China and bedding and clothing is mostly disinfection with high pressure steam, but is treated for different Sterilization thing needs to enter to disinfect using different pressure conditions, but has the utensil at small dead angle less for some at present It is convenient to use this disinfection way, and in general spray disinfection can not function well as the effect of sterilization, therefore, it is necessary to open Send out high-efficiency steam chlorination equipment a kind of.
