When the angle needs to be adjusted, the servo motor 509 in the lifting mechanism 5 is reversed to lower the human model 9 to the lowest position, and the output end of the telescopic cylinder 601 in the flipping mechanism 6 is extended, driving the first connecting pin 602 away from the telescopic cylinder 601, and then driving the second fixed head 603 away from the telescopic cylinder 601, driving the second rotating shaft 604 to extend, and the first fixed seat 605 to extend, so that one end of the mounting plate 11 rotates around the first rotating shaft 607, and the rotating arm 606 rotates around the first rotating shaft 607, thereby driving the human model 9 to rotate around the second rotating shaft 604, and the human model 9 can rotate 90 degrees.

After the double-headed motor is powered on, it starts, and the double-headed motor drives the first connecting shaft 2804 to rotate, and the first connecting shaft 2804 drives the driving gear 2803 to rotate, and the driving gear 2803 is meshed with the driven gear 2805, and the driven gear 2805 drives the sliding shell 2802 to rotate, and the threads on the inner wall of the sliding shell 2802 match the threads on the surface of the screw rod 2801, so that the sliding shell 2802 rotates and rises relative to the screw rod 2801, and the sliding shell 2802 slides relative to the chassis 1, so as to adjust the height of the human model 9. At the same time, the double-headed motor drives the second connecting shaft 2812 to rotate, and the second connecting shaft 2812 drives the active bevel gear 2811 to rotate, and the active bevel gear 2811 is meshed with the driven bevel gear, and the driven bevel gear drives the flip rod 2810 to rotate, thereby driving the flip table 2808 to deflect at an angle, so as to adjust the display angle of the human model 9.

[0063] See also Figure 8 , Fig. 9 and Fig.10 The teaching system body 27 includes a tooth pressure sensor module 19, a central control module 25, an esophagus sensor module 20, a trachea sensor module 21, a display module 22, a voice reminder module 23, a mode selection module 24 and a scoring module 26. The tooth pressure sensor module 19 establishes a data connection with the central control module 25, the central control module 25 establishes data connections with the esophagus sensor module 20 and the trachea sensor module 21 respectively, the central control module 25 establishes a data connection with the display module 22, the central control module 25 establishes data connections with the voice reminder module 23 and the mode selection module 24, and the central control module 25 establishes a data connection with the scoring module 26.

[0064] The tooth pressure sensing module 19 is installed on the teeth of the human body model 9. The human body model 9 is provided with an esophageal tube 17 and a tracheal body 18. The esophageal sensing module 20 is installed inside the esophageal tube 17. The tracheal sensing module 21 is installed inside the tracheal body 18. Fig.11 The display module 22 includes a highlighting unit 221, a display interaction unit 222, a brightness adjustment unit 223 and a color adjustment unit 224. The highlighting unit 221 is used to highlight the structure of the human body model 9, the display interaction unit 222 is used to interact with teaching staff through display content, the brightness adjustment unit 223 is used to adjust the display brightness, and the color adjustment unit 224 can adjust the display color according to the display environment.

[0065] In clinical operation, it is necessary to take into account three factors: correctly inserting the endotracheal tube into the airway rather than the esophagus, causing as little damage to the patient as possible, and reducing the operation time. Therefore, a tongue surface sensor module can also be set on the tongue surface of the human body model 9. During the intubation operation, the time starts to be calculated when the tongue surface sensor module senses the change in contact pressure, and the time is terminated when the tracheal sensor module 21 or the esophagus sensor module 20 senses the change in atmospheric pressure. The contact pressure refers to the pressure generated by the laryngoscope blade lifting the tongue surface, which represents the start of the intubation operation. Atmospheric pressure refers to the pressure generated by the need to connect the endotracheal tube through the resuscitation bag and squeeze the gas in the resuscitation bag into the trachea or esophagus after the tube is placed, which represents the completion of the intubation operation. As long as the tongue surface sensor module is triggered, the timing is started. During the timing time, even if it is triggered multiple times, it will not affect the timing seconds. After the operation is completed, the display module 22 will display the maximum pressure value of the tongue surface sensor module. During the entire timing cycle, as long as the tooth pressure sensor module 19 is triggered, the display module 22 will display the maximum pressure value of the tooth pressure sensor module 19 after the operation is completed. The larger the value, the greater the damage to the upper alveolar during the operation. The maximum pressure value of the tooth pressure sensor module 19 can be compared with the maximum pressure value of the tongue surface sensor module. The smaller the difference between the two values, the greater the damage to the upper alveolar during the operation. During the operation, as long as the tracheal sensor module 21 is triggered, it means that the catheter is successfully placed, the timing ends, the success display light is on, and the display module 22 displays the entire operation time. During the operation, as long as the esophageal sensor module 20 is triggered, it means that the catheter fails, the timing ends, the failure display light is on, and the display module 22 displays the entire operation time. The operation time, the maximum pressure value of the tongue surface sensor module, the maximum pressure value of the tooth pressure sensor module 19, and the success or failure display light displayed by the display module 22 are objective information in four aspects that can be used for teachers to score and provide feedback to students.

[0066] When using the teaching system of the tracheal intubation teaching model, the mode selection module 24 on the controller 4 is used to select the working mode. When the teaching demonstration mode is selected, the height of the human model 9 can be raised to the specified position by the lifting mechanism 5 or the adjustment mechanism 28. When the intubation mode is selected by the mode selection module 24, the angle of the human model 9 can be adjusted to the horizontal by the flipping mechanism 6 or the adjustment mechanism 28. If the student inserts the intubation into the esophageal tube 17, the esophageal sensor module 20 is compressed at this time, and a signal is transmitted to the central control module 25. The central control module 25 transmits the signal to the voice reminder module 23. The voice reminder module 23 performs a voice reminder of an operation error, and the red light on the display module 22 flashes to remind the intubation operation error. If the intubation tube is inserted into the tracheal body 18, the tracheal sensor module 21 inside the tracheal body 18 is compressed, and a signal is transmitted to the central control module 25. The central control module 25 transmits the signal to the voice reminder module 23. The voice reminder module 23 generates a voice reminder of successful intubation, and the green light on the display module 22 flashes to remind the operation is successful. When the intubation hits the teeth, the tooth pressure sensor module 19 is compressed and generates a pressure signal, which is transmitted to the central control module 25. The central control module 25 transmits the signal to the voice reminder module 23, and the voice reminder module 23 generates a voice reminder of the tooth pressure. After the intubation operation is completed, the scoring module 26 scores the operation, and the intubation into the tracheal body 18 is scored 100 points, and the intubation into the esophageal tube 17 is scored 0 points. Each time the tooth pressure sensor module 19 is compressed, 20 points are deducted. After the scoring is completed, the display module 22 displays the score.

[0067] The teaching system of the tracheal intubation teaching model installs sensors on the trachea, esophagus and teeth respectively. When the intubation is successful, wrong or the teeth are under pressure, the corresponding sensors will generate signals to transmit to the voice reminder module 23 to remind the success or failure of the intubation, and the scoring module 26 scores according to the results of the intubation, thereby improving the practicality of the device. By setting the display module 22, the highlighting unit 221 highlights the key structures, the brightness adjustment unit 223 adjusts the display brightness, and the color adjustment unit 224 adjusts the display color according to the display environment, thereby increasing the interactivity between the human model 9 and the teaching staff.
