Integrated cardio-pulmonary resuscitation machine metering calibration device

The invention relates to an integrated cardio-pulmonary resuscitation machine metering calibration device, which belongs to the field of metering calibration of medical equipment and comprises a central processing unit, a display module, a displacement sensor, an automatic rebound device, a flow sensor and a pressure sensor. The displacement sensor is arranged on a pressing platform of the cardiopulmonary resuscitation machine and is used for acquiring displacement data of a pressing head of the cardiopulmonary resuscitation machine, so that the pressing depth, the pressing frequency and the pressing release ratio of the cardiopulmonary resuscitation machine are measured; the automatic springback device is arranged below the pressing platform and used for simulating automatic springback of the chest of the human body; the flow sensor obtains the blowing frequency and the tidal volume of ventilation by monitoring gas flow information in the ventilation process. The pressure sensor is connected with a blowing a
