Description
Technical Field
The invention belongs to the field of medical waste treatment devices, relates to a movable device, and particularly relates to a movable vehicle-mounted medical waste emergency treatment system.
Background
Medical waste belongs to the first hazardous waste (HW01) in the national hazardous waste list, and if the medical waste is not properly treated, secondary infection can be caused, so that the disease continues to spread.
For large and medium cities, the medical waste disposal industry is relatively mature at present. However, for some small medical institutions, such as community hospitals, urban outpatients, rural clinics, etc., due to wide distribution range or remote places, the collection, transportation and disposal links are difficult to be incorporated into the urban medical waste centralized disposal system. In addition, when a serious epidemic situation outbreak or a sudden natural disaster occurs, the generation amount of medical waste is increased suddenly and even exceeds the maximum bearing capacity of the medical waste centralized disposal system, and finally the problem that the medical waste cannot be disposed in time is caused. The movable vehicle-mounted medical waste disposal device can provide sufficient guarantee for a medical waste disposal system with flexibility, convenience and reasonable operation cost.
At present, the treatment of medical waste is generally carried out by adopting two processes of high-temperature steam sterilization and packaging and crushing. The process can adopt the following routes: the method comprises three process forms of firstly crushing and then carrying out steam treatment, firstly carrying out steam treatment and then crushing, and simultaneously carrying out steam treatment and crushing, wherein the three process forms are as follows:
(1) crushing after steam treatment
This is the most widely used treatment technique in north america and other countries, as represented by the united states. Medical waste is pushed into a sterilization room by a container, a bin door of the sterilization room is closed, high-temperature steam is introduced to sterilize the medical waste, the bin door is opened after the steam treatment is finished, and then the material is crushed, destroyed, compressed and packaged. The process form has the advantages that: the medical waste after the high-temperature steam treatment meets the high-degree sanitary standard, and the operation risk of a subsequent crushing section can be reduced, such as: the crushing process can not generate dust with bacteria, workers do not have the problem of infection and pathogenicity caused by pathogenic bacteria remained in the crushing equipment during the maintenance of the crushing equipment, and the crushing equipment does not need extra chemical disinfection measures usually. The process is mature in form and wide in application.
(2) Crushing and then steam treatment
The medical waste is firstly crushed into smaller particle size by a crusher and then enters steam treatment equipment for disinfection treatment. The advantages are that: on one hand, after the package of the medical waste is damaged, the medical waste is directly exposed to high-temperature steam, on the other hand, the contact area of the broken medical waste and the high-temperature steam is larger, and therefore the sterilization effect is easily ensured. However, according to the investigation results of the national institute of health and research on the medical waste treatment plant in Washington State, the instant pressure generated by the crushing of a large amount of hematogen pathogens during the crushing process is released into the atmosphere. Because a large amount of gas containing pathogenic bacteria is generated in the whole crushing process and needs to pass through a filter and a pipeline conveying system, the leakage of hematogen pathogenic bacteria is easy to generate, the diffusion and the propagation of the pathogenic bacteria are generated, the maintenance is very inconvenient, and the crusher is not easy to clean and sterilize after being polluted. The use of this form of process is generally not recommended.
(3) The steam treatment and the crushing are carried out simultaneously
The method is a treatment technology represented by Canada, medical waste is crushed by a mechanical stirring device in the process of steam treatment in a sterilization room, and stirring is carried out to destroy the package of the medical waste so that the medical waste is directly exposed in a steam atmosphere, and stirring and turning over the medical waste can ensure that the medical waste is heated more uniformly, so that the steam treatment effect is improved. A fine crushing device is also needed after the steam treatment. However, in actual operation, the fabrics in the medical wastes such as gauze and bandage often twine the mechanical stirring device, which causes the equipment not to operate normally, and in addition, the sterilization pot is not easy to clean and is inconvenient for maintenance.
According to the comparison, the mobile vehicle-mounted medical waste emergency treatment system adopts a process route of firstly performing steam sterilization and then crushing and packaging. However, the existing mobile vehicle-mounted medical waste emergency treatment devices still have some defects: the feed inlet and the discharge outlet of the steam sterilization pot are not separated; the lack of an exhaust gas collection and treatment system, the risk of pathogenic bacteria being airborne around; a corresponding wastewater treatment system is lacking.
