Medical wastes belong to dangerous wastes, and disposable medical wastes used in hospitals and clinics are disinfected and destroyed on the spot according to regulations and then are transported to a designated place in a centralized manner to be destroyed, so that the medical wastes cannot be reused. The used medical syringes are common medical wastes, and most hospitals adopt a distributed treatment method at present, namely, a collection barrel is arranged in a treatment room of each nursing unit, a proper disinfectant is prepared, medical staff puts the used medical syringes into the collection barrel to soak and disinfect, and then manually destroys the syringes, and the purpose of disinfection is to prevent residual liquid medicine in the syringes from damaging the skin of operators, and the destroyed syringes are intensively sent to a waste disposal site to be destroyed. This method has the following problems: (1) the medical staff manually destroys the sterilized syringe, which consumes large manpower, has high operation difficulty and low working efficiency; (2) the surface and the interior of the injector soaked by the disinfectant can remain part of the disinfectant, and as the injector is hard and brittle, the disinfectant can splash to the skin or eyes of medical staff when the medical staff destroys the injector manually, causing serious injury, and the broken fragments generated by the injector can also splash everywhere to scratch the skin of the medical staff.
