The trigger module 226 is inserted into the pressure sensing terminal 24, and the charging component 227 extends through the plug handle 23 to the other end of the plug handle 23, so as to charge the data acquisition module 22 through the data line. When the piston unit 2 is pushed to the bottom of the empty cylinder 1, the trigger module 226 is pressed and activated, and a signal is given to the data acquisition module 22. The data processing chip carried by the data acquisition module 22 uses the value of the position sensor at this time as the initial value, which is used for the reference of the subsequent calculation of the accurate position, and sends the collected data directly to the external communication connected device through the wireless transmission module 223 and the signal acquisition component 224.

The outer edge of the empty cylinder 1 is clamped in the rotating groove 32 to prevent the piston unit 2 from accidentally detaching from the empty cylinder 1, resulting in the spillage of the medicine. A through hole 33 is provided in the center of the base plate 31 for the outer shell 21 to pass through. A connecting rod 34 is provided on the inner side of the base plate 31. The connecting rod 34 passes through the limit groove 211 and is clamped with a slider 35.

[0050] Working principle: First, the outer edge of the empty cylinder is clamped in the rotating groove to complete the closed installation of the piston unit and the empty cylinder. Then, the piston unit is pushed to the bottom of the empty cylinder to squeeze the plug and transmit the force to the trigger module, which is triggered and activated, and the signal is given to the data acquisition module. The data processing chip carried by the data acquisition module uses the value of the position sensor at this time as the initial value, which is used as a reference for the subsequent calculation of the accurate position. After the activation of the trigger module is completed, the piston unit is pulled to move away from the empty cylinder, and the medicine is sucked into the syringe from the head of the empty cylinder. After the filling of the medicine is completed, the piston unit is pushed to perform the injection operation. In this process, the pressure sensing component at the end of the piston unit collects pressure data, and the signal acquisition component abutting the inner wall of the outer shell collects the electrical signal generated by the displacement. Both sets of data are sent directly to the external communication connected device through the wireless transmission module, and calculated by the external algorithm software to improve the accuracy of the data, thereby facilitating the accurate monitoring of the injection dose or aspiration volume during teaching or research and development.
