Description

Technical Field

[0001] The invention belongs to the technical field of garbage bin disinfection, and in particular is a medical garbage bin disinfection device and a disinfection method based on an electronic curtain accelerator. Background Art

[0002] Medical waste refers to waste with direct or indirect infectious, toxic and other harmful properties generated by medical institutions in medical treatment, prevention, health care and other related activities, including infectious, pathological, damaging, pharmaceutical and chemical wastes. These wastes contain a large number of bacterial viruses, and have certain characteristics of space pollution, acute viral infection and latent infection. If they are not managed and discarded at will, and allowed to mix with domestic waste and spread into people's living environment, they will pollute the atmosphere, water sources, land, animals and plants, cause disease transmission, and seriously endanger people's physical and mental health. All medical waste and domestic waste must not be mixed. Therefore, there are strict management requirements for the generation, transportation and treatment of medical waste. After loading medical waste, the medical waste bin will be first centralized and classified in hospitals and other places of use, and then the waste treatment station will send a special vehicle from the hospital's waste storage location to the centralized disposal of medical waste. In this process, in order to avoid the impact of pollution sources on transportation personnel, vehicles, environment, etc., it is necessary to disinfect the periphery of the closed medical waste bin before transporting it to the medical waste treatment center. After the garbage is dumped out and the inside and outside of the trash can are centrally treated and disinfected, it will be transported back to hospitals and other places of use.

[0003] The periphery of medical waste bins is a special type of waste bin due to its use environment and the danger of storing waste inside. Although there are waste bins with sterilization functions, such as those with ultraviolet light disinfection or fully automatic high-temperature steam disinfection, they are often aimed at the inside of the waste bin, disinfecting the inside of the waste bin and the waste inside, and lack disinfection of the outside of the waste bin. At present, in order to block the transmission route during waste transfer, chemical disinfectants can only be sprayed on the periphery of the waste bin before transfer. This open-air spraying not only requires fully protected staff, but is also harmful to the environment, time-consuming and labor-intensive, and easy to cause human infection.

[0004] Therefore, it is necessary to provide a medical waste bin disinfection device and method based on an electronic curtain accelerator to solve the problems raised in the above background technology. Summary of the invention
