Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Specific examples are given below.

[0022] Embodiment 1 See also Figure 1-Figure 9 The present invention provides a first aid training device, including a first aid training device of the present invention, including a training dummy body 1. In order to facilitate the cardiopulmonary resuscitation training of simulating artificial respiration, a training dummy head 2 is fixedly connected to one side of the training dummy body 1, and a training dummy mouth 3 is fixedly connected to the top of the training dummy head 2. In order to facilitate the compression simulation training of cardiopulmonary resuscitation through the training dummy body 1, a pressing seat 4 is fixedly connected to the top of the training dummy body 1. A metronome 5 is arranged at one end of the training dummy body 1. The bottom end of the metronome 5 is rotatably connected to a support frame 39. Both ends of the top of the metronome 5 are fixedly connected to a broadcasting speaker 49. When the trainee is performing cardiopulmonary resuscitation training, the metronome 5 is started, and then the metronome 5 plays the sound of the compression frequency through the broadcasting speaker 49, so as to help the trainee maintain the standard compression frequency of 100 times per minute from the clamping seat to 120 times per minute on the first support rod. By maintaining the standard compression frequency, the metronome 5 helps to provide a more effective training frequency, thereby improving the frequency of the trainee during compression training; The sub-chamber component is arranged at a position inside the training dummy body 1, and the pressing seat 4 is used in conjunction with the sub-chamber component. When the trainee releases the first layer of limit on the sub-chamber component, the pressing seat 4 is used to press downward, so that the chest resistance of the trainee is similar to the chest pressure of a child. When the trainee releases the second layer of limit on the sub-chamber component, the chest resistance of the trainee is similar to the chest pressure of an adult, so that the trainee can feel the difference between cardiopulmonary resuscitation for children and adults during training, thereby improving the training effect of the trainee and improving the applicability of the training; A counting component is arranged between the training dummy body 1 and the metronome 5, and the pressing seat 4 is used in conjunction with the counting component. When the trainee presses the training dummy body 1 through the pressing seat 4, each downward pressing stroke drives the counting component to operate, and then the counting component drives the display screen 48 on the metronome 5 to record the number of pressing times by the number of times the pressing seat 4 is pressed downward, so that the trainee can conduct targeted training on the number of pressings per minute and the conversion of different numbers of artificial respirations performed according to different pressing strengths for adults and children during cardiopulmonary resuscitation training, thereby improving the targeted training effect and further improving the trainee's proficiency in cardiopulmonary resuscitation.

[0023] Embodiment 2 like Figure 2-Figure 5 As shown, in order to facilitate compression training with different chest resistances for adults and children on the training dummy body 1, the chamber assembly includes a chamber plate 6, a return spring 7, a first airbag resistance ball 8 and a second airbag resistance ball 9.

The chamber plate 6 located at the top end of the training dummy body 1 fits with the pressing seat 4, and the chamber plate 6 located at the bottom end of the training dummy body 1 fits with the pressing seat 4. The dividing chamber plate 6 at the end is fixedly connected to the training dummy body 1. In order to quickly reset the pressing seat 4 after pressing it downward, a plurality of reset springs 7 are fixedly connected between two adjacent dividing chamber plates 6. When the trainee only presses the second airbag resistance ball 9, the resistance of the gas in the second airbag resistance ball 9 makes the chest pressure to which the trainee is subjected when pressing be similar to that of a child. When the trainee presses the second airbag resistance ball 9 and the first airbag resistance ball 8 at the same time, the resistance of the gas in the first airbag resistance ball 8 and the second airbag resistance ball 9 makes the chest pressure to which the trainee is subjected when pressing be similar to that of an adult.

[0024] In order to facilitate the release of the limit on the chamber plate 6, the chamber assembly also includes a clamping seat 10, a clamping column 11, a first support rod 12 and a second support rod 13. The two ends of the chamber plate 6 are fixedly connected with the clamping seat 10, and the inner side of the clamping seat 10 is fixedly connected with the clamping column 11. The ring sides of the clamping columns 11 at the bottom and top ends of the training dummy body 1 are rotatably connected with the first support rod 12, and the two sides of the ring side of the clamping column 11 located at the center position of the training dummy body 1 are rotatably connected with the second support rod 13. The second support rod 13 is rotatably connected to the corresponding first support rod 12, so as to facilitate the downward travel of the pressing seat 4 to be limited by the cooperation of the first support rod 12 and the second support rod 13.

[0025] The sub-cavity assembly also includes a limiting rod 14, a limiting strip 15, a clamping piece 16 and a clamping frame 17. The adjacent ends of the first support rod 12 and the second support rod 13 are plugged and connected to the limiting rod 14, so as to facilitate the limiting rod 14 to limit the first support rod 12 and the second support rod 13 on the sub-cavity plate 6. In order to facilitate pulling the limiting rod 14 to move away from the sub-cavity plate 6, the end of the limiting rod 14 away from the sub-cavity plate 6 is fixedly connected to the limiting strip 15. In order to facilitate the limiting rod 14 to move in the direction away from the sub-cavity plate 6, the limiting rod 14 is fixedly connected to the limiting strip 15.

In order to facilitate the release of the limit rod 14 clamped with the cavity plate 6 for limiting, a clamping frame 17 is fixedly connected to the outside of the training dummy body 1 and at a position corresponding to the clamping piece 16.

[0026] During operation, when it is necessary to perform a simulated chest compression training for a child on the training dummy body 1, the trainer pulls the limit rod 14 in a direction away from the cavity plate 6, thereby pulling the clamping piece 16 on the limit rod 14 to the position of the clamping frame 17, and then rotating the clamping piece 16 to the clamping frame 17, and applying a force to the limit bar 15 to move toward the cavity plate 6 through the elastic characteristics of the clamping spring 50, and the clamping piece 16 is clamped on the clamping frame 17 through the force, thereby releasing the limit on the second airbag resistance ball 9. After the limit on the second airbag resistance ball 9 is released, the trainer presses the second airbag resistance ball 9 downward through the pressing seat 4, and then through the air resistance inside the second airbag resistance ball 9, the trainer performs a simulated training of the child's chest compression with appropriate force; When the user needs to perform adult chest compression simulation training on the training dummy body 1, the trainee releases the limit on the first airbag resistance ball 8 according to the above steps, and then when the trainee presses the pressing seat 4 downward, the air resistance inside the first airbag resistance ball 8 and the second airbag resistance ball 9 enables the trainee to perform appropriate force training simulation of adult chest compression.

[0027] Embodiment 3 like Figure 5-Figure 9 As shown, in order to count the number of presses when performing chest simulation training through the pressing seat 4, the counting component includes a fixed plate 18, an air guide tube 19, a first air guide hose 20, a sliding seat 21, a moving rod 22 and an air guide rack 23. The fixed plate 18 is fixedly connected to the inside of the training dummy body 1 and close to the training dummy head 2, and one end of the top of the fixed plate 18 is fixedly connected to the air guide tube 19. In order to facilitate the operation of air in the air guide tube 19 and to facilitate the injection of air in the air guide tube 19 into the metronome 5, the end of the air guide tube 19 away from the fixed plate 18 is plugged and connected with the first air guide hose 20, the inside of the air guide tube 19 is slidably connected with the sliding seat 21, and the end of the sliding seat 21 away from the first air guide hose 20 is fixedly connected with the moving rod 22. In order to facilitate the movement of the sliding seat 21 and the moving rod 22 in the air guide tube 19, the moving rod 22 is fixedly connected to the side away from the training dummy head 2.

[0028] The counting assembly also includes a transmission column 24, a first transmission gear 25, a fixed square column 26, a rotating shaft 27, a first bevel gear 29, a second bevel gear 30 and a transmission rack 31. The top of the training dummy body 1 and the position corresponding to the air guide tube 19 are rotatably connected with the transmission column 24, and the ring side of the bottom end of the transmission column 24 is fixedly connected with the first transmission gear 25. In order to facilitate the transmission column 24 and the first transmission gear 25 to rotate, the air guide rack 23 is meshed and connected with the first transmission gear 25. The top of the air guide tube 19 and the side corresponding to the transmission column 24 are fixedly connected with a fixed square column 26. The top of the fixed square column 26 is rotatably connected with a plurality of rotating shafts 27, and the center position of the rotating shaft 27 is fixedly connected with The second transmission gear 28 and the end of the rotating shaft 27 close to the transmission column 24 are fixedly connected with the first bevel gear 29, and the ring side of the transmission column 24 and the position corresponding to the rotating shaft 27 are fixedly connected with the second bevel gear 30. In order to facilitate the second bevel gear 30 to rotate, the first bevel gear 29 is meshed and connected with the second bevel gear 30. The dividing cavity plate 6 located at the top of the training dummy body 1 is fixedly connected with a transmission rack 31 on one side close to the training dummy head 2, so as to facilitate the transmission column 24 to rotate through the downward movement of the pressing seat 4. The second transmission gear 28 is meshed and connected with the transmission rack 31, so as to facilitate the second transmission gear 28 and the first bevel gear 29 to rotate through the transmission rack 31.

[0029] In order to prevent the gas in the metronome 5 from flowing back into the air guide tube 19, the counting assembly also includes an air guide crook 32, an air intake pipe 33 and a closing seat 34. The end of the first air guide hose 20 away from the training dummy body 1 is plugged and connected with the air guide crook 32. In order to facilitate the introduction of the air pushed out of the air guide tube 19 into the metronome 5, the end of the air guide crook 32 away from the first air guide hose 20 is provided with an air guide hole. In order to facilitate the next intake of air into the air guide tube 19, one side of the air guide crook 32 is fixedly connected with the air intake pipe 33, and the inner sides of the air guide hole and the air intake pipe 33 are fixedly connected with the closing seat 34.

[0030] In order to facilitate limiting the flow direction of gas in the air guide crook 32, the counting component also includes a closing frame 35, a closing strip 36 and a closing piece 37.

The closing seat 34 in the air intake pipe 33 and the closing seat 34 in the air guide hole are oppositely arranged. The closing piece 37 on the closing seat 34 in the air guide hole is arranged at a position away from the first air guide hose 20, and the closing piece 37 on the closing seat 34 in the air intake pipe 33 is arranged at a position close to the air guide crook 32.

[0031] During operation, when air is injected into the air guide crook 32 through the air guide tube 19, the air flowing into the air guide crook 32 drives the closing piece 37 in the air intake pipe 33 and its corresponding closing seat 34 to close, and drives the closing piece 37 in the air guide hole to open on the corresponding closing seat 34. Conversely, when gas is extracted through the air guide tube 19, the gas in the air guide crook 32 drives the closing piece 37 in the air intake pipe 33 to open on the corresponding closing seat 34, and drives the closing piece 37 in the air guide hole to open on the corresponding closing seat 34, and then extracts the gas for next use into the air guide tube 19 through the air intake pipe 33. When gas is extracted through the air guide tube 19, it is prevented from extracting gas in the metronome 5.

[0032] In order to facilitate the counting on the display screen 48 by adjusting the gas flowing in the air guide tube 19, the counting assembly also includes a second air guide hose 38, a support frame 39, a linkage box 40, a linkage column 41, a transmission fan 42 and a counting column 43.

The center position of the linkage box 40 is rotatably connected with a linkage column 41. The transmission fan 42 is fixedly connected to the ring side of the linkage column 41 located inside the linkage box 40, and then the airflow generated in the air guide tube 19 is introduced into the linkage box 40 through the linkage tube, driving the transmission fan 42 and the linkage column 41 to rotate. The end of the linkage column 41 located outside the linkage box 40 is fixedly connected with a counting column 43, so that the counting column 43 is driven to rotate outside the linkage box 40 through the rotation of the transmission fan 42.

[0033] The counting assembly also includes a reset seat 44, a reset plate 45, a counting button 46 and a counting spring 47. The reset seat 44 is fixedly connected to the center position of the metronome 5 and the position corresponding to the counting column 43. The reset plate 45 is rotatably connected to the inner side of the reset seat 44. The counting button 46 is fixedly connected to the center position of the metronome 5 and the position corresponding to the reset plate 45, so that it is convenient to press the counting button 46 by driving the reset plate 45 through the counting column 43. A reset leather cover is arranged on the outside of the counting button 46. After each pressing, the counting button 46 will automatically reset at the same time after the reset plate 45 is automatically reset. The counting button 46 is electrically connected to the display screen 48, so that the counting spring 47 is automatically reset after the counting column 43 and the reset plate 45 are disconnected. The counting spring 47 is fixedly connected to the end of the reset plate 45 away from the reset seat 44, and the top of the counting spring 47 is fixedly connected to the metronome 5.

[0034] During operation, after the gas discharged from the air guide tube 19 is introduced into the linkage box 40 through the second air guide hose 38, the transmission fan 42 and the linkage column 41 are driven to rotate, and then the linkage column 41 drives the counting column 43 to rotate. When the counting column 43 rotates to a position in contact with the reset plate 45, it drives the counting button 46 to be pressed, and then the pressed counting button 46 is counted through the display screen 48. Each time the trainee presses, the airflow is discharged outward through the air guide tube 19, and then the trainee's each layer of pressing is counted through the display screen 48. The number of pressings per minute and the conversion of different numbers of artificial respirations performed according to different pressing strengths for adults and children can be targeted, thereby improving the targeted training effect and further improving the trainee's proficiency in cardiopulmonary resuscitation.
