Description

Technical Field

[0001] The present invention belongs to the technical field of first aid training devices, and specifically relates to a first aid training device. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is an emergency rescue measure. For patients with cardiac arrest, performing CPR immediately within four minutes of cardiac arrest helps the patient restore breathing, heartbeat, and consciousness. CPR can save the patient's life at a critical moment, especially in the emergency situation of cardiac arrest. Timely CPR operation is crucial.

[0003] For example, patent (CN118430369A) discloses a cardiopulmonary resuscitation first aid demonstration teaching device, which records: including a housing and a pressing mechanism located inside the housing. The pressing mechanism includes a pressing plate, a pressure membrane, a fixed seat, a lifting seat, a first air pipe, a first airbag, a locking tongue, and a resistance adjustment component; the pressing plate is installed on the chest on the front side of the housing, the pressure membrane is embedded in the pressing plate, and the pressure membrane is in contact with the housing; the lower part of the fixed seat is connected to the rear side of the housing; the lifting seat is sleeved outside the fixed seat; a locking groove is provided above the fixed seat, the locking tongue is elastically rotatably installed on the lifting seat, and the locking tongue passes through the window and is inserted into the locking groove; a baffle is provided at the window of the lifting seat; the pressure membrane is connected to the first airbag through the first air pipe, the first airbag is fixedly attached to the baffle, and the first airbag is located between the baffle and the locking tongue. The present invention is used for the teaching demonstration and training of cardiopulmonary resuscitation, and can adjust the resistance of external chest compression, so as to be applicable to different people, with a wide range of applications and flexible and convenient use.

[0004] Existing cardiopulmonary resuscitation training dummies can conveniently simulate the pressures of different chest cavities of children and adults through simple resistance adjustment during training. However, during the training process of existing cardiopulmonary resuscitation, although the external chest compression frequencies of both children and adults are 100 to 120 times per minute, because the breathing frequency of children is faster than that of adults, more artificial respiration times are required per minute during cardiopulmonary resuscitation. When the existing cardiopulmonary training dummy is used by a trainer for training, it can only simply train the pressing force, and the targeted training effect for the accurate number of chest compressions of children and adults and the interval between compression and artificial respiration is poor. Therefore, in view of the above problems, a first aid training device is proposed. Summary of the Invention

[0018] Advantages of the present invention:

[0019] The present invention provides a first aid training device. Through the structural cooperation design of the pressing seat and the counting assembly, when the trainer presses the training dummy's body through the pressing seat, with each downward pressing stroke, it drives the counting assembly to operate. Then, the counting assembly drives the display screen on the metronome to record the number of presses by the number of times of pressing the pressing seat downward. Thus, it is convenient for the trainer to specifically train the number of presses per minute during cardiopulmonary resuscitation training and to switch between different artificial respiration times according to different pressing forces for adults and children, improving the specific training effect and further enhancing the trainer's proficiency in mastering cardiopulmonary resuscitation.

[0020] The present invention provides a first aid training device. Through the structural cooperation design of the pressing seat and the cavity-dividing assembly, when the trainer releases the first-layer limit of the cavity-dividing assembly and presses downward through the pressing seat, the chest resistance received by the trainer is similar to the chest pressure of a child. Then, when the trainer releases the second-layer limit of the cavity-dividing assembly, the chest resistance received by the trainer is similar to the chest pressure of an adult. Thus, it is convenient for the trainer to differentially feel the differences in cardiopulmonary resuscitation for children and adults during training, improving the trainer's training effect and the applicability of the training.

[0021] The present invention provides a first aid training device. Through the structural cooperation design of a metronome and a broadcast speaker, when a trainer conducts cardiopulmonary resuscitation training, by starting the metronome, the metronome then plays the sound of the pressing frequency through the broadcast speaker, helping the trainer maintain the standard pressing frequency of BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] The following gives specific embodiments.

[0036] Embodiment 1

[0037] Please refer to Figures 1-9, the present invention provides a first aid training device, including a training dummy body 1. For the convenience of cardiopulmonary resuscitation training 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. For the convenience of performing cardiopulmonary resuscitation pressing simulation training 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, and a broadcast speaker 49 is fixedly connected to both ends of the top of the metronome 5. When the trainer is performing cardiopulmonary resuscitation training, by starting the metronome 5, the metronome 5 then plays the sound of the pressing frequency through the broadcast speaker 49 to help the trainer maintain a standard pressing frequency of 100 to 120 times per minute. By maintaining the standard pressing frequency, the metronome 5 helps to provide a more effective training frequency, thereby improving the frequency of the trainer during pressing training;

[0038] A cavity-dividing component, which is arranged at the position inside the training dummy body 1. The pressing seat 4 is used in cooperation with the cavity-dividing component. When the trainer releases the first-layer limit of the cavity-dividing component, by pressing down the pressing seat 4, the chest cavity resistance received by the trainer is similar to the chest cavity pressure of a child. Then, when the trainer releases the second-layer limit of the cavity-dividing component, the chest cavity resistance received by the trainer is similar to the chest cavity pressure of an adult. Thus, it is convenient for the trainer to differentially feel the differences in cardiopulmonary resuscitation for children and adults during training, improving the training effect of the trainer and the applicability of the training;

[0039] A counting component, which is arranged at the position between the training dummy body 1 and the metronome 5. The pressing seat 4 is used in cooperation with the counting component. When the trainer presses the training dummy body 1 through the pressing seat 4, through the stroke of each downward press, it drives the counting component to operate. Then, the counting component drives the display screen 48 on the metronome 5 to record the number of presses according to the number of times of pressing down the pressing seat 4. Thus, it is convenient for the trainer to specifically train the number of presses per minute during cardiopulmonary resuscitation training and the conversion of different artificial respiration times according to different pressing forces for adults and children, improving the specific training effect and further improving the proficiency of the trainer in mastering cardiopulmonary resuscitation.

[0040] Embodiment 2

[0041] Such as Figures 2-5As shown in the figure, in order to facilitate the chest compression training with different chest resistances for adults and children on the training dummy body 1, the cavity dividing assembly includes a cavity dividing plate 6, a return spring 7, a first airbag resistance ball 8 and a second airbag resistance ball 9. A plurality of cavity dividing plates 6 are arranged inside the training dummy body 1 at positions corresponding to the pressing seat 4. A first airbag resistance ball 8 is fixedly connected between two cavity dividing plates 6 at the bottom end of the training dummy body 1. A second airbag resistance ball 9 is fixedly connected between two cavity dividing plates 6 at the top end of the training dummy body 1. The cavity dividing plate 6 at the top end of the training dummy body 1 is in contact with the pressing seat 4, and the cavity dividing plate 6 at the bottom end of the training dummy body 1 is fixedly connected to the training dummy body 1. In order to make it quickly return to its original position after pressing down the pressing seat 4, a plurality of return springs 7 are fixedly connected between adjacent two cavity dividing plates 6. When the trainer only presses the second airbag resistance ball 9, the resistance of the gas in the second airbag resistance ball 9 makes the chest pressure received by the trainer during pressing similar to that of a child. When the trainer presses the second airbag resistance ball 9 and the first airbag resistance ball 8 simultaneously, the resistance of the gas in the first airbag resistance ball 8 and the second airbag resistance ball 9 makes the chest pressure received by the trainer during pressing similar to that of an adult.

[0042] In order to facilitate the release of the limit on the cavity dividing plate 6, the cavity dividing assembly further includes a clamping seat 10, a clamping column 11, a first support rod 12 and a second support rod 13. Clamping seats 10 are fixedly connected to both ends of the cavity dividing plate 6. A clamping column 11 is fixedly connected to the inner side of the clamping seat 10. First support rods 12 are rotatably connected to the circumferential sides of the clamping columns 11 at the bottom end and the top end of the training dummy body 1. Second support rods 13 are rotatably connected to both sides of the circumferential side of the clamping column 11 at the central position of the training dummy body 1. The second support rod 13 is rotatably connected to the corresponding first support rod 12, thereby facilitating the limitation of the downward stroke of the pressing seat 4 through the cooperation of the first support rod 12 and the second support rod 13.

[0043] The cavity-dividing assembly further includes a limiting rod 14, a limiting strip 15, a clamping piece 16 and a clamping frame 17. Limiting rods 14 are inserted and connected to the adjacent ends of the first support rod 12 and the second support rod 13, so as to facilitate the limitation of the first support rod 12 and the second support rod 13 on the cavity-dividing plate 6 through the limiting rods 14. In order to facilitate pulling the limiting rod 14 to move away from the cavity-dividing plate 6, a limiting strip 15 is fixedly connected to the end of the limiting rod 14 away from the cavity-dividing plate 6. In order to facilitate the automatic reset of the limiting rod 14 when the cavity-dividing plate 6 needs to be limited, a clamping spring 50 is fixedly connected to one end of the limiting strip 15 close to the cavity-dividing plate 6. The end of the clamping spring 50 away from the limiting strip 15 is fixedly connected to the training dummy body 1. The limiting rod 14 is slidably connected to the training dummy body 1. A clamping piece 16 is rotatably connected to the top of the limiting strip 15. In order to facilitate the limitation of the limiting rod 14 that is disengaged from the cavity-dividing plate 6, a clamping frame 17 is fixedly connected to the outer side of the training dummy body 1 at a position corresponding to the clamping piece 16.

[0044] During operation, when it is necessary to perform child chest compression simulation training on the training dummy body 1, the trainer pulls the limiting rod 14 in the direction away from the cavity-dividing plate 6, thereby pulling the clamping piece 16 on the limiting rod 14 to the position of the clamping frame 17, and then rotating the clamping piece 16 to the clamping frame 17. The elastic force characteristic of the clamping spring 50 applies a force to the limiting strip 15 to move towards the cavity-dividing plate 6, and the clamping piece 16 is clamped on the clamping frame 17 through this force, thereby releasing the limitation on the second airbag resistance ball 9. After the limitation 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 simulation training with an appropriate force for child chest compression;

[0045] When the user needs to perform adult chest compression simulation training on the training dummy body 1, the trainer follows the above steps to release the limitation on the first airbag resistance ball 8. Then, when the trainer presses the pressing seat 4 downward, through the air resistance inside the first airbag resistance ball 8 and the second airbag resistance ball 9, the trainer performs simulation training with an appropriate force for adult chest compression.

[0046] Embodiment III

[0047] As Figures 5-9As shown, in order to count the number of presses during chest cavity simulation training by pressing seat 4, the counting component includes a fixed plate 18, an air diversion pipe 19, a first air guide hose 20, a sliding seat 21, a moving rod 22, and a air guide rack 23. Inside the training dummy body 1 and near the position of the training dummy head 2, there is a fixed connection with a fixed plate 18. One end of the top of the fixed plate 18 is fixedly connected with an air diversion pipe 19. In order to facilitate driving the air to operate inside the air diversion pipe 19 and to facilitate injecting the air inside the air diversion pipe 19 into the metronome 5, the end of the air diversion pipe 19 away from the fixed plate 18 is connected with a first air guide hose 20 in a plug-in connection. Inside the air diversion pipe 19, there is a sliding connection with a sliding seat 21. The end of the sliding seat 21 away from the first air guide hose 20 is fixedly connected with a moving rod 22. In order to facilitate driving the sliding seat 21 and the moving rod 22 to move inside the air diversion pipe 19, on the side of the moving rod 22 away from the training dummy head 2, there is a fixed connection with an air guide rack 23.

[0048] The counting component further 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. At the top of the training dummy body 1 and at a position corresponding to the air diversion pipe 19, there is a rotational connection with a transmission column 24. The circumferential side of the bottom end of the transmission column 24 is fixedly connected with a first transmission gear 25. In order to facilitate driving the transmission column 24 and the first transmission gear 25 to rotate, the air guide rack 23 is meshed with the first transmission gear 25. On the top of the air diversion pipe 19 and on one side corresponding to the transmission column 24, there is a fixed connection with a fixed square column 26. At the top of the fixed square column 26, there are multiple rotating shafts 27 in a rotational connection. At the central position of the rotating shaft 27, there is a fixed connection with a second transmission gear 28. At the end of the rotating shaft 27 close to the transmission column 24, there is a fixed connection with a first bevel gear 29. At the circumferential side of the transmission column 24 and at positions corresponding to the rotating shafts 27, there are fixed connections with second bevel gears 30. In order to facilitate driving the second bevel gears 30 to rotate, the first bevel gear 29 is meshed with the second bevel gear 30. On the side of the sub-chamber plate 6 at the top of the training dummy body 1 close to the training dummy head 2, there is a fixed connection with a transmission rack 31. Thus, it is convenient to drive the transmission column 24 to rotate through the downward movement stroke of the pressing seat 4. The second transmission gear 28 is meshed with the transmission rack 31. Thus, it is convenient to drive the second transmission gear 28 and the first bevel gear 29 to rotate through the transmission rack 31.

[0049] To prevent the gas in the metronome 5 from flowing back into the air guide tube 19, the counting assembly further includes a gas guide elbow column 32, an intake pipe 33, and a closing seat 34. The end of the first gas guide hose 20 away from the training dummy body 1 is plugged and connected with the gas guide elbow column 32. To facilitate guiding the air pushed out of the air guide tube 19 into the metronome 5, the end of the gas guide elbow column 32 away from the first gas guide hose 20 is provided with a gas guide hole. To facilitate pumping the air for the next introduction into the air guide tube 19, an intake pipe 33 is fixedly connected to one side of the gas guide elbow column 32. Closing seats 34 are fixedly connected to the inner sides of both the gas guide hole and the intake pipe 33.

[0050] To facilitate restricting the gas flow direction in the gas guide elbow column 32, the counting assembly further includes a closing frame 35, a closing strip 36, and a closing piece 37. A closing frame 35 is fixedly connected to the central position of the closing seat 34. A closing strip 36 is rotatably connected to the annular side of the closing frame 35. A closing piece 37 is fixedly connected to the end of the closing strip 36 away from the closing frame 35. The closing piece 37 is in contact with the closing seat 34. The closing seats 34 in the intake pipe 33 and in the gas guide hole are arranged in the opposite direction. The closing piece 37 on the closing seat 34 in the gas guide hole is arranged at a position away from the first gas guide hose 20, and the closing piece 37 on the closing seat 34 in the intake pipe 33 is arranged at a position close to the gas guide elbow column 32.

[0051] During operation, when injecting air into the gas guide elbow column 32 through the air guide tube 19, the air flowing into the gas guide elbow column 32 drives the closing piece 37 in the intake pipe 33 to close with its corresponding closing seat 34, and drives the closing piece 37 in the gas guide hole to open on its corresponding closing seat 34. On the contrary, when extracting gas through the air guide tube 19, the gas in the gas guide elbow column 32 drives the closing piece 37 in the intake pipe 33 to open on its corresponding closing seat 34, and drives the closing piece 37 in the gas guide hole to open on its corresponding closing seat 34, thereby pumping the gas for the next use into the air guide tube 19 through the intake pipe 33, and preventing it from extracting the gas in the metronome 5 when extracting gas through the air guide tube 19.

[0052] To facilitate adjusting the count on the display screen 48 by the gas flowing in the air duct 19, the counting assembly further includes a second air duct hose 38, a support frame 39, a linkage box 40, a linkage column 41, a drive fan 42 and a counting column 43. The bottom end of the metronome 5 is fixedly connected to the linkage box 40. To facilitate guiding the air flow in the air duct 19 into the linkage box 40, a linkage pipe is fixedly connected to the bottom end of the linkage box 40. The end of the second air duct hose 38 away from the first air duct hose 20 is inserted and connected to the linkage pipe. A linkage column 41 is rotatably connected to the center position of the linkage box 40. A drive fan 42 is fixedly connected to the circumferential side of the linkage column 41 inside the linkage box 40. Thus, the air flow generated in the air duct 19 is guided into the linkage box 40 through the linkage pipe to drive the drive fan 42 and the linkage column 41 to rotate. The end of the linkage column 41 outside the linkage box 40 is fixedly connected to the counting column 43. Thus, it is convenient to drive the counting column 43 to rotate outside the linkage box 40 by the rotation of the drive fan 42.

[0053] The counting assembly further includes a reset seat 44, a reset piece 45, a counting button 46 and a counting spring 47. A reset seat 44 is fixedly connected to the center position of the metronome 5 and corresponding to the counting column 43. A reset piece 45 is rotatably connected to the inside of the reset seat 44. A counting button 46 is fixedly connected to the center position of the metronome 5 and corresponding to the reset piece 45. Thus, it is convenient to drive the reset piece 45 to press the counting button 46 by the counting column 43. A reset leather sleeve is arranged outside the counting button 46. The counting button 46 after each press will be automatically reset simultaneously after the reset piece 45 is automatically reset. The counting button 46 is electrically connected to the display screen 48. Thus, it is convenient for the counting spring 47 to be automatically reset after the counting column 43 is disconnected from the reset piece 45. The end of the reset piece 45 away from the reset seat 44 is fixedly connected to the counting spring 47. The top end of the counting spring 47 is fixedly connected to the metronome 5.

[0054] During operation, when the gas exported from the air duct 19 is introduced into the linkage box 40 through the second air duct hose 38, it drives the drive fan 42 and the linkage column 41 to rotate. Thus, the linkage column 41 drives the counting column 43 to rotate. When the counting column 43 rotates to the position where it fits with the reset piece 45, it drives the counting button 46 to be pressed. Thus, the pressed counting button 46 counts the number of times through the display screen 48. Thus, each press of the trainer will export air flow outward through the air duct 19. Thus, the number of presses of each layer of the trainer is counted through the display screen 48, which can train the number of presses per minute targeted, and convert different artificial respiration times according to different pressing forces of adults and children, improve the targeted training effect, and further improve the proficiency of the trainer in mastering cardiopulmonary resuscitation.
