[0030] The implementation principle of a chest compression training model of the embodiment of the present application is as follows: first, the model is stood up by the fixing plate 1, so that it is convenient to teach the parts on the model and to recognize the parts of the human organs. After the recognition teaching of the human organs is completed, the switch plate 10 is manually opened by the handle 11, and the switch plate 10 is rotated by the first rotating shaft. The switch plate 10 opens the placement slot 9, and the display 16 in the placement slot 9 is manually taken out. The display 16 is placed beside the model through the first connecting line 14 and the second connecting line 15. Then the model is laid down, and the two support frames 17 are manually rotated. The two support frames 17 are respectively rotated by the two second rotating shafts, so that the two support frames 17 support the display 16. 17 are adjusted to different angles respectively, so that the display 16 can be placed at different angles to facilitate observation of the display 16, and the protective cover 18 on the display 16 is manually removed.

The receiving plate 49 receives the sensing information of the first sensing block 20, the second sensing block 21 and the third sensing block 22, and then concentrates it in the receiver 47. Then, the second sliding plate 7 is pressed, so that the second sliding plate 7 drives the second support plate 27 to move, and the first support plate 23 drives the multiple first springs 28 to contract, so that the bottom of the first support plate 23 contacts the two first sensing blocks 20, the two second sensing blocks 21 and the two third sensing blocks 22. The second support plate 27 drives the plurality of second springs 29 to contract, so that the bottom of the second support plate 27 contacts the two fourth sensing blocks 24, the two fifth sensing blocks 25 and the two sixth sensing blocks 26. The receiving plate 49 receives the sensing information of the fourth sensing block 24, the fifth sensing block 25 and the sixth sensing block 26, and then concentrates it in the receiver 47. It is identified by the recognition module to facilitate the distinction between different sensing blocks, and then displayed on the display 16 through the sound and light module. The sound and light modules of different sensing blocks are displayed on the display 16, making it easy to know whether the pressed area is a valid pressing area. At the same time, when the first support plate 23 moves, it drives the first electrode plate 30 to move, and the first electrode plate 30 contacts the second electrode plate 32, so that the second electrode plate 32 is pressed. The plate 32 starts the motor through the circuit in the connecting pipe 33, and the motor drives the transmission shaft 35 to rotate, and the transmission shaft 35 drives the fan blades 36 to rotate. The wind pressure generated by the fan blades 36 is discharged through the air outlet pipe 37, and then discharged from the air inlet 39 through the contraction tube 38, so that it can simulate that the human body will exhale gas when pressing, making the sense of reality in learning more intense. At the same time, two water pumps 41 are started, and the two water pumps 41 draw water from the two water tanks 40 respectively. The water flows into the second water pipe 43 through the two first water pipes 42 respectively, and the water flows into the third water pipe 44 through the second water pipe 43 and then is discharged. It can simulate the water flow spit out by the human body during cardiopulmonary resuscitation after drowning, so that the sense of reality can be improved. Then artificial respiration is performed at the air inlet 39.The gas entering from the air inlet 39 enters the air outlet 37 through the contraction tube 38. The air flow detector 45 in the air outlet 37 detects the blown gas and displays it on the display 16, so that it is easy to know whether the blown gas is effective.

[0031] Example 2 The difference between this embodiment and the first embodiment is that an air bag is provided on the inner wall of the model head 6, and a one-way valve and an exhaust valve are provided on the air bag. When artificial respiration is performed on the model head 6, the gas blown in is collected by the air bag through the one-way valve. A detector is provided outside the air bag to detect the air bag so that the amount of gas blown in can be known and whether the amount of gas blown in is qualified. This facilitates the practice of artificial respiration. After the practice is completed, the exhaust valve is opened to allow the gas in the air bag to be discharged.

[0032] Example 3 The difference between this embodiment and the first embodiment is that: a nozzle is provided on the third water pipe 44, and a valve is provided on the nozzle. When the nozzle is not in use, the valve is closed to prevent the nozzle from spraying water. When it is needed, the valve is opened. A second through groove is provided on one side of the connecting block 5, and a collecting tank is slidably connected to the second through groove. After the teaching is completed, the two water pumps 41 are started to make the water flow sprayed from the nozzle through the third water pipe 44. The sprayed water cleans the air outlet 12. The collecting tank is manually pulled out, and the collecting tank collects the cleaned waste water, which is convenient for treating the waste water.

[0033] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
