Abstract
The invention provides a disinfecting method for medical waste, which comprises the steps of: evacuating a sealed container and then injecting above 135 DEG C steam for a period of time, then evacuating and then injecting above 135 DEG C steam, repeating the operation for several times, and finally injecting a disinfecting solution to complete the disinfecting process. Under a vacuum state, virus can be more thoroughly killed by adopting high-temperature steam disinfection for many times and matching with the disinfecting solution.
Description
Technical field
The present invention relates to a kind of sterilization method of Biohazard Waste.
Background technology
Biohazard Waste (also being referred to as medical waste) has the total space and pollutes, features such as acute infection and latency pollution, the hazardness of the microorganism that it contained be common sanitary waste tens, hundreds of even thousands of times, as deal with improperly, can become hospital infection and social environment public hazards source, the more serious source that becomes disease popularity.
Contain in various degree antibacterial, virus and harmful substance in the Biohazard Waste.And the Organic substance in the refuse not only grows mosquitos and flies and causes transmission of disease, and the ammonia (NH3) that discharges when corruption is decomposed, hydrogen sulfide foul gass such as (H2S), generates multiple harmful substances, and atmosphere pollution is detrimental to health; Also be to cause cross infection and air-polluting main cause in the hospital simultaneously.Especially the pathogen in the infectious garbage may be advanced people's human body by approach such as mucosas by the otch on respiratory system, digestive system, the skin, breakage or the wound that punctures.In addition, body fluid also is the route of transmission of pathogen.
The harm that present Treatment of Medical ' Waste mode exists: common Biohazard Waste processing method has: burning, chemical disinfection, steam sterilization, radiosterilization, sanitary landfills etc.But exist following drawback:
1) discharges tens kinds and even hundreds of metal " flying dust " and sour gas in the burning process, have a strong impact on health.
2) Biohazard Waste landfill disposal need occupy a large amount of soils, causes the land resource waste.Because Biohazard Waste content of organics height certainly will cause environment, soil and underground water source to be subjected to secondary pollution difficult the decomposition, and health is constituted harm.
3) Biohazard Waste is transported to the transportation of handling in the concentrated area from medical institutions such as hospitals, what pathogenic bacteria, virus on the way can not stopped disseminates, and brings the risk of potential secondary pollution to society.
4) plastic cement such as tube for transfusion, needle tubing, plastic gloves, refuse bag are arranged in the Biohazard Waste; Metals such as syringe needle are also arranged; Cotton goods such as binder, gauze, cotton thread are also arranged.Burn and bury and to have wasted the material of recyclable utilizations such as a large amount of plastic cement, metal all, wasted natural resources.
One of method that is commonly used at present to handle Biohazard Waste mainly is to carry out disinfection by disposable high-temperature steam, and only often can not thoroughly kill virus with the primary steam sterilization.
Summary of the invention
The object of the present invention is to provide a kind of sterilization method of Biohazard Waste, to improve the disinfectant effect.
For achieving the above object, sterilization method provided by the invention is that the steam that a sealed container is evacuated more than back injection 135 degree is continued for some time, and then the above steam of 135 degree is injected in the back that is evacuated, for several times, inject disinfectant solution at last repeatedly, finish disinfecting process.
The sterilization method of described Biohazard Waste, wherein the persistent period is 2-5 minute.
The sterilization method of described Biohazard Waste, wherein the total time of several can be 20 minutes-40 minutes according to the character of garbage repeatedly.
The present invention can kill part virus under the vacuum anaerobic condition, kill part virus then under high-temperature steam again, repeats to carry out disinfection through disinfectant solution more at last for several times, can kill virus fully basically.
Description of drawings
Fig. 1 is a device sketch map of the present invention.
Primary clustering symbol description in the accompanying drawing:
1 disinfection tank; 2 lids; 3 bleeding points; 4 steam inlets; 5 air pumps; 6 control valves of bleeding; 7 steam generators; 8 steam control valves; 9 disinfectant solution imports; 10 disinfectant solution control valves; 11 disinfectant solution tanks.
The specific embodiment
The present invention injects high-temperature steam after one sealed container is evacuated to continue several minutes, and then the back injection high-temperature steam that is evacuated, and several injects disinfectant solution at last repeatedly, finishes disinfecting process.
Device that the present invention adopts as shown in Figure 1, disinfection tank 1 is a sealed container, the sealing container has an openable lid 2.Also be provided with a bleeding point 3 and a steam inlet 4 and disinfectant solution import 9 on the sealed container tank body, bleeding point 3 connects an air pump 5, is used for disinfection tank 1 is evacuated; Steam inlet 4 connects a steam generator 7, and this steam generator 7 is used for producing and provide high-temperature steam in disinfection tank 1, and disinfectant solution import 9 connects a disinfectant solution tank 11.
Because sterilization method of the present invention is an evacuation and to inject high-temperature steam be to hocket, therefore on bleeding point 3 or air pump 5, be provided with a control valve 6 of bleeding that is used to control disinfection tank 1 internal pressure; On steam inlet 4 or steam generator 7, be provided with a steam control valve 8.
At first Biohazard Waste is put into disinfection tank 1, close lid 2.Switch valve 8 on the steam generator is under the closed condition, start air pump 5, with disinfection tank 1 inside be evacuated (being negative pressure), close the control valve 6 of bleeding, open steam control valve 8 and in disinfection tank 1, inject high temperature (more than 135 degree) steam, continue 2-5 minute, steam off control valve 8, the unlatching control valve 6 of bleeding is evacuated disinfection tank 1 inside, repeats aforementioned process, and multiple total time can be 20 minutes-40 minutes according to the character of garbage.
Unlatching disinfectant solution control valve 10 injects disinfectant solution in disinfection tank 1 kills virus, and finishes whole disinfecting process.The present invention adopts under vacuum state, and the multiple high temp vapor sterilization also cooperates disinfectant solution to kill virus more completely.
Device of the present invention is known technology, can be that all can seal and have the container of placing internal cavities of objects such as disinfection tank; Steam generator can be all equipment that can produce the above steam of 135 degree; Air pump can be all pumps that gas in the disinfection tank can be extracted out; Disinfectant solution can be all disinfectant that can use.
Claims (3)
1. the sterilization method of a Biohazard Waste is that the steam that a sealed container is evacuated more than back injection 135 degree is continued for some time, and then injects 135 after being evacuated and spend above steam that several injects disinfectant solution at last repeatedly, finishes disinfecting process.
2. according to the sterilization method of the described Biohazard Waste of claim 1, wherein, the persistent period is 2-5 minute.
3. according to the sterilization method of the described Biohazard Waste of claim 1, wherein, Shuo Ci total time is 20 minutes-40 minutes repeatedly.
