[0040] It should be noted that the disinfectant for the internal circuit of the anesthesia machine provided by the present utility model is mainly used for disinfecting the internal circuit of the anesthesia machine. Therefore, the internal circuit 70 of the anesthesia machine is further included in the present utility model, and the gas inlet and outlet on the internal circuit 70 of the anesthesia machine are respectively an air supply port 010 and a gas return port 020. The internal circuit 70 of the anesthesia machine is connected to the atomization module 40 through the first gas pipeline.
