Description

Technical Field

[0001] The present invention relates to the technical field of medical training, in particular to a cardiac resuscitation simulation training device. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is one of the commonly used methods in first aid. It can effectively solve the problem of patients losing heartbeat and breathing after fainting due to drowning, car accidents, fire or their own physical reasons, so as to save people's lives. There are relevant CPR training in medical training and other professional institutions. During CPR training, specially designed dummy models are usually used to conduct simulated practical training of CPR, so that trainees can better learn and master the relevant operating methods and techniques.

[0003] When performing cardiopulmonary resuscitation, the depth of chest compressions, the air volume and the air blowing time during artificial respiration will be different for people with different body shapes. For people with a fatter body, a relatively larger compression depth and a relatively larger air volume are required during artificial respiration, and the air blowing time can be slightly prolonged to ensure the effect of cardiopulmonary resuscitation. However, when performing simulated training of cardiopulmonary resuscitation through a training model, the training model cannot simulate the automatic adjustment of the compression depth, air blowing volume and air blowing time under people with different body shapes, making the simulation training method of the trainees relatively single, and affecting the effect of the simulated training of cardiopulmonary resuscitation. For this reason, we propose a cardiopulmonary resuscitation simulation training device. Summary of the Invention

[0042] The control component 7 is arranged on the upper side of the support member 12 and is used to randomly adjust the time of secretion reflux of the anti-liquid component 6 during cardiac resuscitation simulation.

[0043] When performing cardiac resuscitation simulation training through the human body model 11, the body shape simulation component 2 can be randomly adjusted by the adjustment component 5, so that the body shape simulation component 2 can randomly simulate the fat and thin body shapes of different human bodies on the human body model 11, thereby increasing the authenticity of the simulation training. The compression depth component 3 can automatically adjust the required compression depth under the current body shape according to the different body shapes simulated by the body shape simulation component 2 regulated by the adjustment component 5, so as to simulate training for different chest compression depths under different body shapes, and trigger reminders for the minimum and maximum limits of the compression depth to prevent invalid compressions caused by failing to reach the minimum limit of the compression depth, and to prevent damage to the human body caused by exceeding the maximum limit of the compression depth.

[0044] The body simulation assembly 2 includes a ventilation tube 21 fixedly connected to the interior of the mannequin 11. The mannequin 11 is made of silicone. The end of the ventilation tube 21 away from the mannequin 11 is fixedly connected to the output end of the air pump 22. The air pump 22 is fixedly connected to the upper side of the support member 12. The input end of the air pump 22 is connected to an air inlet pipe, and a filter is installed on the air inlet pipe to filter the gas filled into the mannequin 11. An exhaust pipe 23 is fixedly connected to one side of the mannequin 11. Solenoid valves are installed on the exhaust pipe 23 and the ventilation tube 21. A controller is provided on the upper side of the support member 12.

[0045] By controlling the operation of the air pump 22, gas is delivered to the interior of the human body model 11 through the ventilation tube 21, so that the human body model 11 can be expanded outward. By controlling the amount of gas delivered to the human body model 11, the degree of expansion of the human body model 11 can be adjusted, thereby simulating different body shapes of different people and increasing the authenticity of the simulation training.

[0046] The adjusting component 5 includes a first connecting member 51 and a gravity ball 511. The first connecting member 51 is fixedly connected to the support member 12. A first enclosure 52 is provided on the upper side of the first connecting member 51. Seventh springs 53 fixedly connected to the first connecting member 51 are fixedly connected on both sides of the first enclosure 52. A first annular groove adapted to the first enclosure 52 is provided on the upper side of the first connecting member 51. Initially, under the elastic force of the seventh spring 53, the first enclosure 52 is pressed into the first annular groove. A plurality of tubular members 54 are fixedly connected to the lower side of the first connecting member 51 at equal intervals around the circumference, and the first connecting member 51 is located on the inner side of the first enclosure 52 and is provided with a slope toward the plurality of tubular members 54. The inner sliding device of the tubular member 54 A connecting block 55 is provided, and a limiting groove adapted to the connecting block 55 is provided on the inner side of the tubular member 54. The connecting block 55 is slidably arranged along the limiting groove, which can guide the up and down movement of the connecting block 55. A fifth spring 56 fixedly connected to the tubular member 54 is fixedly connected to the lower side of the connecting block 55, and a sixth switch 57 is provided on the upper side of the connecting block 55. A plurality of protective shells 58 are fixedly connected to the side end of the first connecting member 51 at equal intervals around the circumference. A resistor block 59 is provided inside the protective shell 58. The resistor block 59 is electrically connected to the air pump 22 and the second electromagnet 318, and the resistance values ​​of the plurality of resistor blocks 59 are different from each other. The plurality of resistor blocks 59 are respectively electrically connected to the plurality of sixth switches 57. An indicator light 510 is provided on the upper side of the protective shell 58.

[0047] During simulation training, the gravity ball 511 is placed from the upper end of the first enclosure 52, so that the gravity ball 511 randomly enters one of the tubular members 54 under the action of gravity and presses against the sixth switch 57 in the tubular member 54, which controls the air pump 22 to work for a certain period of time and connects the corresponding resistor block 59 to the circuit. When the resistance of the connected resistor block 59 is large, the power of the air pump 22 will be small, so that the amount of gas delivered to the human body model 11 within a certain period of time is small, and the expansion degree of the human body model 11 is small, simulating a relatively thin body shape. Otherwise, it simulates a relatively fat body shape. Therefore, by adjusting the component 5, the body shape simulation component 2 can be randomly adjusted to simulate different body shapes. After the air pump 22 stops working, the solenoid valve on the ventilation pipe 21 will be controlled to close.

[0048] The compression assembly 3 includes a mounting shell 31 fixedly connected to the inner side of the human body model 11. A gear rod 32 is slidably provided on the upper side of the mounting shell 31. The upper end of the gear rod 32 is fixedly connected to the human body model 11. A bellows 34 is sleeved on the outer side of the gear rod 32. The upper and lower ends of the bellows 34 are respectively fixedly connected to the gear rod 32 and the mounting shell 31. When compression is performed during cardiopulmonary resuscitation, the gear rod 32 will move up and down, causing the bellows 34 to expand and contract. The arrangement of the bellows 34 can prevent the gas filled into the human body model 11 from entering the mounting shell 31. A pressure plate 35 is slidably provided on the outer side of the gear rod 32. Guide rods 36 fixedly connected to the mounting shell 31 are slidably provided on both sides of the pressure plate 35. A first spring 37 fixedly connected to the mounting shell 31 is symmetrically fixedly connected to the lower side of the pressure plate 35.

[0049] A connecting shell 38 fixedly connected to the pressure plate 35 is provided on both sides of the gear rod 32. A first electromagnet 39 is fixedly connected to the inner side of the connecting shell 38. A beveled tooth block 310 is slidably provided on the inner side of the connecting shell 38 and is attracted to the first electromagnet 39. The beveled tooth block 310 cooperates with the gear rod 32. A second spring 311 fixedly connected to the connecting shell 38 is symmetrically fixedly connected to one side of the beveled tooth block 310.

[0050] When air is injected into the mannequin 11 via the air pump 22, the expansion of the mannequin 11 drives the gear member 32 upward. The engagement of the beveled tooth blocks 310 on both sides with the beveled tooth grooves on both sides of the gear member 32 prevents the gear member 32 from moving upward. During CPR compressions, the gear member 32 is pressed downward. The engagement of the beveled tooth blocks 310 with the gear member 32 drives the beveled tooth blocks 310 and the connecting shell 38 downward, causing the pressure plate 35 to move downward along the guide rod 36. The first spring 37 is compressed, and then, under the elastic force of the first spring 37 and the internal air pressure of the mannequin 11, the pressure plate 35 and the gear member 32 are moved upward and reset. This process is repeated.

[0051] The inner side of the mounting shell 31 is fixedly connected with a mounting member 312, which is located on one side of the pressure plate member 35. The two sides of the pressure plate member 35 are set as arc-shaped end surfaces to facilitate the pressure on the first switch 313 and the second switch 315. The first switch 313 is respectively provided on the upper and lower sides of the mounting member 312, and a moving block 314 is slidably provided on one side of the mounting member 312. A first guide groove adapted to the moving block 314 is provided on one side of the mounting member 312. The moving block 314 is slidably provided between the first switches 313 on the upper and lower sides along the first guide groove. Second switch 315, a first magnet 317 is fixedly connected to the upper side of the moving block 314, a second electromagnet 318 that repels the first magnet 317 is fixedly connected to one side of the mounting member 312, a third spring 316 fixedly connected to the mounting member 312 is fixedly connected to the lower side of the moving block 314, and three first warning lights 33 are respectively provided on the upper side of the support member 12, the upper first switch 313 is electrically connected to one of the first warning lights 33, the lower first switch 313 is electrically connected to the second first warning light 33, and the second switch 315 is electrically connected to the third first warning light 33.

[0052] When the adjustment component 5 randomly presses one of the sixth switches 57 and controls the corresponding resistor block 59 to be connected to the circuit, the different body shapes of the human model 11 can be adjusted. The magnetic strength of the second electromagnet 318 can be adjusted accordingly, generating a repulsive effect on the first magnet 317, causing the movable block 314 to move downward to a position corresponding to the current body shape. The third spring 316 is compressed. When the resistance value of the connected resistor block 59 is large, the human model 11 simulates a thinner body shape. At this time, the magnetic strength of the second electromagnet 318 is also small, causing the movable block 314 to move downward a smaller distance, corresponding to a smaller pressing depth. Conversely, when the simulated body shape is fatter, the movable block 314 moves downward a larger distance, corresponding to a larger pressing depth.

[0053] When performing CPR compressions, the gear member 32 drives the pressure plate member 35 to move downward. When the pressure plate member 35 presses against the upper first switch 313, one of the first warning lights 33 will sound an alarm, indicating that the minimum compression depth limit has been reached. This is to prevent invalid compressions from not reaching the minimum compression depth limit. When the pressure plate member 35 continues to move downward and presses the second switch 315, the third first warning light 33 will be controlled to sound an alarm, indicating that the required compression depth for the current body size has been reached. If the compression depth is not properly controlled and the pressure plate member 35 continues to move downward and presses the lower first switch 313, the second first warning light 33 will be controlled to sound an alarm, indicating that the maximum compression depth limit has been reached. Continuing to press at this time may cause harm to the human body. In this way, random simulation training of compression depths for different body sizes can be performed, and the control of the minimum and maximum compression depth limits can be mastered, thereby improving the simulation training effect of chest compressions.

[0054] After the simulation training is completed, the first electromagnet 39 is energized to generate an adsorption effect on the bevel gear block 310, so that the bevel gear block 310 is separated from the gear rod 32, and the solenoid valve on the exhaust pipe 23 is controlled to open to discharge the gas in the human body model 11, so that the gear rod 32 moves down and resets.

Initially, the slider 46 presses the fourth switch 410, and the plurality of third switches 49 are electrically connected to the plurality of sixth switches 57 respectively. The greater the resistance value of the resistor block 59 corresponding to the sixth switch 57, the closer the corresponding third switch 49 is to the third electromagnet 45. Two second warning lights 416 are respectively provided on the upper side of the support member 12. The third switch 49 closest to the third electromagnet 45 is electrically connected to one of the second warning lights 416, and the plurality of third switches 49 are electrically connected to the other second warning light 416.

To limit the movement of the pressing block 414; a plurality of fifth switches 415 are provided on the other side of the shell 44, and the plurality of fifth switches 415 are electrically connected to the plurality of sixth switches 57 respectively, and the greater the resistance value of the resistor block 59 corresponding to the sixth switch 57, the closer the corresponding fifth switch 415 is to the motor 411, and two third warning lights 417 are respectively provided on the upper side of the support member 12, and the fifth switch 415 closest to the motor 411 is electrically connected to one of the third warning lights 417, and the plurality of fifth switches 415 are electrically connected to the other third warning light 417.

[0057] When the adjustment component 5 randomly presses one of the sixth switches 57, when the resistance value of the corresponding connected resistor block 59 is larger, a thinner body shape is simulated, and the third switch 49 corresponding to the side closer to the third electromagnet 45 is controlled to be turned on, and the fifth switch 415 corresponding to the side closer to the motor 411 is controlled to be turned on. During artificial respiration during cardiopulmonary resuscitation, the trainee blows air into the mouth of the human model 11, which can enter the first bladder 42 through the air blowing tube 43, causing the first bladder 42 to expand, thereby also causing the chest of the human model 11 to rise and fall, which can also be used as a basis for blowing judgment. At the same time, the air pressure in the first bladder 42 will increase, and the first bladder 42 will be increased. 2, the pressure detected by the air pressure sensor increases, causing the third electromagnet 45 to have a greater repulsive effect on the second magnet 47, causing the slider 46 to move away from the third electromagnet 45, and the fourth spring 48 to compress, so that the slider 46 no longer presses the fourth switch 410, and the output end of the motor 411 will be controlled to drive the screw 412 to rotate, so that the pressure block 414 moves away from the motor 411. When the slider 46 moves to press the third switch 49 closest to the third electromagnet 45, one of the second warning lights 416 will be controlled to sound a warning, indicating that the minimum limit of the blowing volume has been reached. When the pressure block 414 moves to press the fifth switch 414 closest to the motor 411, the pressure block 414 will be controlled to sound a warning. 5, one of the third warning lights 417 will be controlled to sound a warning, indicating that the minimum limit of the blowing time has been reached, which means that the blowing is effective at this time. When the slider 46 moves to a third switch 49 that is pressed and turned on, another second warning light 416 will be controlled to sound a warning, indicating that the blowing amount required for the current body size has been reached. If the pressing block 414 moves to a fifth switch 415 that is pressed and turned on at this time, another third warning light 417 will be controlled to sound a warning, indicating that the current required blowing time has been reached. If the pressing block 414 has not yet pressed the fifth switch 415 on the side closest to the motor 411 at this time, it means that the blowing time is short, which means that the blowing is too fast. , which may cause harm to the human body, or the blowing is ineffective. If the pressing block 414 presses against the corresponding fifth switch 415 in advance, it means that the blowing volume is insufficient, or when the corresponding blowing volume is reached, the blowing time is long and effective blowing cannot be performed. When the pressing block 414 presses against the corresponding fifth switch 415, the output end of the motor 411 can be controlled to drive the screw 412 to reverse. When the pressing block 414 moves in the opposite direction to press against the limit switch on the support block 413 close to the side of the motor 411, the motor 411 stops working for subsequent time detection during blowing. After the blowing stops, the gas in the first capsule 42 will flow out to the outside through the blowing tube 43.
