Medical waste refers to the polluting waste produced by hospitals that have been in contact with patients' blood and flesh. Such as used cotton balls, gauze, tape, waste water, disposable medical equipment, postoperative waste products, expired medicines, etc. According to the medical inspection report of the national health department, because medical waste has the characteristics of space pollution, acute infection and latent pollution, its viruses and bacteria are dozens, hundreds or even thousands of times more harmful than ordinary domestic waste. If it is not handled properly, it will cause serious pollution to the environment and may also become the source of epidemics.

At present, there is not much difference between the existing medical waste bins and the traditional waste bins. Pile all the medical waste together, which is not conducive to sorting. Medical waste is mainly divided into infectious waste, such as disposable items such as cotton swabs, gauze gloves, etc.; devices; pharmaceutical waste, such as expired, obsolete, spoiled or contaminated discarded medicines. When handling mixed medical waste, it needs to be sorted, and the sorting process is likely to endanger the physical and mental health of the staff.
