【Technical field】

The invention relates to the technical field of medical waste treatment, in particular to a medical waste self-cleaning sterilization barrel.

【Background technique】

Medical waste refers to wastes that are directly or indirectly infectious, toxic, and other hazardous wastes produced in medical treatment, prevention, and other related activities. Medical waste may contain a large number of pathogens, microorganisms, or harmful chemicals. It is a type of waste that is different from other wastes. The very dangerous waste that is discarded at random will not only pollute the soil, but also pollute the waters, and even pollute the air, which will cause illness and danger to those who come into contact with it. Medical waste needs to be disinfected and sterilized during recycling, otherwise it cannot be transported safely. In the prior art, there are many sterilization devices for medical waste, but all of them only sterilize and sterilize the surface of medical waste. Considering, for example, how to kill bacteria and viruses inside masks and gloves, high temperature or ultraviolet light alone cannot eliminate them well. Therefore, it is urgent to design a medical waste sterilization barrel that can target the inner layer of medical waste.

【Content of invention】
