technical field

The invention relates to the technical field of medical waste, in particular to a sorting device and a sorting method for metallic medical waste.

Background technique

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

There are many types of medical waste, such as medical needles, scalpels, disposable medical equipment, disposable medical supplies, domestic waste used by patients, etc. These wastes are often mixed together when they are thrown away.
