Description
[technical field]
This utility model relates to air sterilization sterilizing equipment decontaminating apparatus technical field, specifically a kind of moveable sterilizing station.
[background technology]
Hospital infection, refers to the infection that inpatient and corpsman,hospital obtain in hospital, is included in the infection that the while in hospital occurs and the infection obtaining in hospital and occur after discharge.Hygiene department of China and health care workers attach great importance to the control of hospital infection.
In the U.S., hospital infection rate reaches 5 ~ 10%, and heavy patient room is 10 ~ 39.7%.Particularly in operating room, in heavy patient room, infected most refractory heals the septicemia of one of disease in the average annual infected number nearly 250,000 of the U.S., mortality rate 30 ~ 50%.Hospital is a kind of special fire fighting and rescue, is also one of the most serious place of air pollution.According to the investigation of WHO World Health Organization (WHO), global hospital average rate is 8.7%.Various countries' nosocomial infection incidence fluctuation is 3% ~ 17%, and if the U.S. is 5%, Britain is 7.5%, and Japan is 5.8%.And our country's general hospital infection rate was 5.22%, 37 university affiliated hospital infection rate was 6.25%.
Within 2003,30, the whole world simultaneous SARS the infected of country has 8,398, and wherein healthcare givers has infected 1,707, dead 774.Because the severe acute respiratory syndrome that occurs and bird flu have impelled domestic nearly 48 hospitals to determine to install air cleaning facility on a large scale to the superinfection that various big hospital brings;
Now, severe atmospheric pollution, exacerbates the risk of hospital infection.Air is the primary vehicle of hospital infection.PM2.5 in air is the major vectors of the microorganisms such as antibacterial.PM2.5 is fine grained, can with air motion, the feature of the courses of infection disease that it carries be spread speed fast, involve wide, control difficulty, consequence is serious.Outpatient and emergency and the departments such as hall of infusing of the hygiene departments such as hospital, particularly hospital, various patient carries different pathogenic microorganism and mixes, and Susceptible population assembles, and is easy to produce nosocomial infection, does not have well effectively control method so far.Hospital infection also occurs in the High Risk Departments such as hospital operating room, ICU, CCU intensive care unit(ICU), delivery room, newborn room.
The improvement that indoor air in hospital pollutes is very urgent in sum!
There are three large difficult points in medical environment air sterillization:
1, current air sterilization technique is difficult to meet prophylactic disinfection and terminal disinfection common prescription, as long as prophylactic disinfection controls to certain standard air microbe; And terminal disinfection must the thorough disinfection of patient's contaminated environment.
2, infectious respiratory disease is to concomitant disinfection particular importance, requires the pathogen that patient excretes to be killed at any time, and is difficult to when there being people accomplish that concomitant disinfection purifies.
3, there is people's persistence sterilization in case, be difficult to solve evolutionary rate and pollute rate equation problem; The pollution speed of people's activity is always greater than the purification speed of existing air cleaning facility.
Hospital's regular air sterilization method and deficiency:
1. the sterilization of lactic acid heating fumigating makes to be full of tart flavour in air.
2. must be unmanned with ultraviolet lamps irradiates and ozonization and the time oversize, also can cause aging and injury to object.
3. chemosterilant spray operation improper being not only difficult to is effective, and also easily causes secondary pollution and the abnormal smells from the patient difficult short time of harmful, pungent chemical reagent distributes.
Above 3 kinds of modes are difficult to accomplish continuous sterilization for High Risk Departments such as hospital's hematopathy, blood dialysis room ICU, CCU, and the air quality in this kind of region must be caused like this to meet cleanliness requirements.
Medically air sterillization is defined as the process killing or remove pathogenic microorganism in air.Qualified being defined as of sterilizing makes the microorganism of artificial contamination reduce by 99.9% or natural microorganisms minimizing 90%.And make the microorganism of artificial contamination reduce 99.9999%, be then called sterilizing.The mankind are finding the method for air sterilization always, so far, only have a few countries to grasp the technology of air sterilization.
China Patent No. be 93226519.7 electrostatic air cleaner, China Patent No. be 97234337.7 sterilization air purification machine and China Patent No. be 97106376.1 combined static field device be the earlier application of the applicant, these air cleaners can only reduce 99.99% for the microorganism of artificial contamination in air, and process air quantity is maximum not more than 2500 cubes ms/h, the space that similar hospital transfusion room etc. is larger can not be used for.What key was that above-mentioned utility model adopts is electrostatic technique based on corona discharge.Present this technology is considered to cause the by-products two such as release ozone to be limited to use.
[utility model content]
The purpose of this utility model solves the requirement that existing hospital disinfection equipment can not reach sterilizing, and the problem such as pollutant such as PM2.5 and antibacterial in air can not be reduced rapidly, there is provided one can use in each High Risk Department local environment of hospital, the effect of sterilizing can be reached rapidly, directly the air of cleaning can be delivered to the breathing zone of user, in air, PM2.5 concentration reaches international advanced standard, and the portable sterilizing station of more than 6000 cubes ms/h that this air sterilization apparatus has mobility, process air capacity reaches.
