[0040] Working principle: When using the device, by starting the motor 1 301, the rotating rod 302 can drive the gear 2 303 to rotate, and the gear 2 303 is meshed with the rack plate 305, thereby driving the rack plate 305 to slide, so that the support plate 306 can be moved up and down along the limit slider 307, so as to adjust the height and position of the support plate 306, so that when the support plate 306 descends, the rack plate 206 can be driven to descend synchronously, and the rack plate 206 can drive the connecting rotating rod 204 to rotate by meshing with the gear 1 205, and the rack plate 1 203 can be driven to move by the rotation of the gear 1 205, so that when the support plate 306 descends, the protective plate 202 can be synchronously moved on the inner wall of the workbench 201, thereby providing safety protection for the injection teaching area;

[0041] By starting the second motor 501, the limit rotating rod 502 is driven to rotate, and then the sleeve 503 is driven to rotate, so that the teaching device 4 can be conveniently adjusted in angle, thus providing injection conditions in different directions. By pulling the pull rod 602, the movable slider 601 can be driven to slide along the inner wall of the sleeve 503. Through the action of the connecting rope 603, the block 606 can be moved, thereby compressing the spring 604, so that the block 606 is moved out of the slot 607, so that the fixed block 608 can be conveniently disassembled. When the spring 604 is loosened, the elastic action of the spring 604 causes the block 606 to enter the slot 607, so that the fixed block 608 is clamped and fixed, so that the teaching device 4 can be stabilized and adapted to various teaching tasks. In this way, the syringe 704 can be constrained by the limit rope 703 to complete a stable injection action demonstration;

[0042] The injection operation process is monitored in real time through the data acquisition module, where the pressure sensor, position sensor and tactile sensor collect the force applied by the trainees, position change and tactile feedback data, thereby converting the physical information in the injection process into digital signals. The data transmission module uses the wireless communication unit and the wired interface to quickly and stably transmit the collected data to the data processing and analysis module, and the data encryption unit ensures the transmission security. The data processing and analysis module cooperates with the embedded microcontroller to perform algorithm analysis on the received data, and saves the analysis results through the storage unit, so that the operation records can be queried at any time. The analysis results are instantly generated into audio, visual and tactile feedback through the feedback and interaction module, and the report generator compiles a detailed report to provide trainees with operation improvement suggestions. The user interface module combines the display unit, management unit and touch unit to provide teachers and students with an intuitive operation platform, thus realizing accurate monitoring, instant feedback and visual presentation of injection operations, and ultimately effectively improving teaching quality and learning efficiency.
