The control module 1 is electrically connected to the fourth solenoid valve 64, one end of the first connecting pipe 65 is connected to the fourth solenoid valve 64, the other end of the first connecting pipe 65 is communicated with the first solenoid valve 61 and the second solenoid valve 62, and the fourth solenoid valve 64 has an open state and a closed state.
When the second electromagnetic valve 62 communicates the air suction port 52 with the first connecting pipe 65, the connection state of the air bag module 3 and the air suction port 52 can be adjusted by controlling the opening and closing of the fourth electromagnetic valve 64, so that the air pump 5 can be controlled to suck air from the air bag module 3.

In the present embodiment, the airbag module 3 includes: in order to facilitate inflation and deflation of each air bag, a plurality of fourth electromagnetic valves 64 are provided, and each air bag is connected with a first connecting pipe 65 through a fourth electromagnetic valve 64 corresponding to the air bag. Thus, each fourth electromagnetic valve 64 can control the connection state of a corresponding one of the airbags, and control the air pump 5 to inflate and deflate the corresponding airbag.
In this embodiment, the air bags are provided with six (4-section or single-section air bags may be provided in other embodiments), the first connecting pipe 65 is a three-way pipe, three ends of the first connecting pipe 65 are respectively communicated with the first electromagnetic valve 61, the second electromagnetic valve 62 and the six fourth electromagnetic valves 64, and the six fourth electromagnetic valves 64 can correspondingly control the inflation and the deflation of the six air bags.
Specifically, before one volume measurement, the measurement parameter calibration process needs to be performed first, and the inflation time of the air bag needs to be measured and stored in the control module 1. After the control module 1 receives the measurement starting trigger signal, the control module 1 controls the air pump 5 to start to enter a measurement preparation stage, and in the starting stage, the air bag is firstly subjected to air extraction operation through the operation of the electromagnetic valve. The control module 1 controls the third electromagnetic valve 63 first to make the third electromagnetic valve 63 in a closed state with the atmosphere. Then the control module 1 controls to open the six fourth electromagnetic valves 64 to enable the fourth electromagnetic valves 64 to be conducted with the first connecting pipe 65, then the control module 1 controls the second electromagnetic valve 62 again to enable the second electromagnetic valve 62 to conduct the second connecting pipe 66 and the first connecting pipe 65, the second connecting pipe 66 and the second air port 69 on the second electromagnetic valve 62 are disconnected, meanwhile, the first electromagnetic valve 61 is controlled to enable the third connecting pipe 67 to be disconnected from the first connecting pipe 65, and the third connecting pipe 67 is conducted with the first air port 68 on the first electromagnetic valve 61.
After a series of valve actions are ready, the control module 1 controls the air pump 5 to start working and enter the air extraction stage. After 2 minutes of overall air evacuation, the individual balloons were initially evacuated. A part of the fourth solenoid valve 64 is controlled by the control module 1, and the other solenoid valves remain unchanged. At this time, the air pump 5 starts to pump air from a part of the air bags, for example, the first and fourth solenoid valves 64 can be controlled to be opened, and the first air bag starts to pump air for 1 minute. After the air suction of the first air throttle bag is completed, the control module 1 closes the first fourth electromagnetic valve 64, opens the second fourth electromagnetic valve 64, and starts to suck air from the second air throttle bag, and the air suction time period is 1 minute. And so on until the 6 th air throttle is completely pumped, the control module 1 enters an air inflation preparation stage, in the air inflation preparation stage, firstly, the air pump 5 is closed, the first electromagnetic valve 61 is controlled, the first electromagnetic valve 61 is connected with the third connecting pipe 67 and the first connecting pipe 65, the third connecting pipe 67 is disconnected from the first air port 68 on the first electromagnetic valve 61, the second electromagnetic valve 62 is controlled, the second electromagnetic valve 62 is connected with the second connecting pipe 66 and the second air port 69 on the second electromagnetic valve 62, and the second connecting pipe 66 and the first connecting pipe 65 are disconnected.

After the electromagnetic valve is ready, the air pump 5 is started, the timer in the control module 1 is started, the control module 1 collects data through the pressure/temperature/blood volume sensing module 2 in real time, when the pressure/temperature/blood volume sensing module 2 detects that the pressure reaches 60mmHg, the timer stops timing, the timing duration Tc is obtained, meanwhile, the air pump 5 is closed, all the fourth electromagnetic valves 64 are opened, the third electromagnetic valve 63 is opened, and the air in the air bag is naturally discharged through the third air port 70 on the third electromagnetic valve 63. Tc is stored in the control module 1 as a basic parameter for volume measurement.
