In addition to assisted respiration, ventilators can also be used for nebulization treatment of medicaments. In addition to intravenous administration, many special pulmonary infections are treated by local aerosol inhalation to achieve better phlegm eliminating and expelling effects. In the use process of the breathing machine, the humidifier is required to humidify the air-oxygen mixed gas, and the atomizer is adopted to atomize the liquid medicine, so that the physiological humidification effect is achieved on the nasopharynx part and the respiratory tract of a patient, and a better treatment effect can be achieved.
Because the pipeline between the breathing machine and the patient is longer, particularly when the temperature is lower, the air-oxygen mixed gas humidifier heats, and then when entering the nasopharynx part and the respiratory tract of the patient through the longer pipeline, the temperature of the air-oxygen mixed gas becomes lower, and the respiratory tract of the patient is stimulated, so that the patient is uncomfortable. In order to improve the comfort of patients and meet the physiological temperature requirement, a better treatment effect is achieved, and the air-oxygen mixed gas needs to be heated and insulated.
