| description | The invention relates to a sine breathing device for an airplane oxygen mask test, and belongs to the technical field of breathing devices. The device comprises a driving unit for providing power for the piston movement of a piston cylinder, the piston cylinder for simulating the lung of a human body, a gas pipeline for connecting the piston cylinder and a first three-way valve, an inspiration pipeline and an expiration pipeline which are arranged between the first three-way valve and a second three-way valve, and a mass flow meter arranged on the inspiration pipeline, the heating and humidifying unit is arranged on the expiration pipeline, the pressure thermometer is used for monitoring environment pressure and temperature, and the control unit is electrically connected with the pressure thermometer, the mass flow meter, the first three-way valve, the second three-way valve and the servo electric cylinder. The device can regulate, control and simulate the tidal volume, the respiratory capacity, the expiratio |
