[0002] In infectious disease areas, medical waste is highly infectious, and it is necessary to clean the medical waste in a timely manner. Its collection and treatment are crucial.

[0003] Traditional ordinary medical waste collection devices are mostly fixed or simply mobile, lacking targeted safety protection and efficient collection functions. After the used protective clothing is put into the collection box, the protective clothing will puff up. Since there is no extrusion structure, the stored protective clothing is limited, and it is impossible to collect more protective clothing. In addition, medical staff need to frequently contact medical waste, posing a high risk of infection. Moreover, the manual collection efficiency is low, wasting time, and it is easy to cause problems such as medical waste leakage and inaccurate classification due to fatigue or negligence. And medical staff can only perform unified sterilization and disinfection operations after collecting medical waste. Since sterilization and disinfection cannot be carried out immediately, it may cause secondary pollution and disease transmission, thus threatening the health and safety of personnel.
