Description

Technical Field

[0001] The present invention relates to the technical field of emergency training, and in particular to a pre-hospital emergency training system based on real-time interaction. Background Art

[0002] Pre-hospital emergency care is the primary link in the emergency medical service system, including cardiopulmonary resuscitation, hemostasis, bandaging, fixation, transportation and other rescue measures. It is an important part of medical education, public self-rescue and mutual rescue training and other fields. Cardiopulmonary resuscitation is a resuscitation technique for rescuing cardiac and respiratory arrest and protecting and restoring brain function, that is, using chest compressions to form temporary artificial circulation, using artificial respiration instead of spontaneous respiration, and using AED to perform electric defibrillation as soon as possible to achieve the purpose of restoring consciousness and saving lives.

[0003] Pre-hospital emergency care is a process of comprehensive application of technical skills, but the current mannequins have relatively single functions, and the cardiopulmonary resuscitation mannequins are difficult to reflect the complexity and comprehensiveness of pre-hospital emergency care operations. Due to the sudden nature of pre-hospital emergency care, it is difficult to restore and reproduce the scene, resulting in limited authenticity of simulation teaching and a weak sense of experience for students. The results of emergency care operations cannot be visualized, which is not conducive to students' observation and comprehensive analysis to make accurate judgments.

[0004] The existing mannequins have obvious functional limitations when in use, and the bionic eyeballs cannot react according to real-time situations, resulting in superficial simulation training effects and difficulty in improving students' training results. The mannequin's physiological sign simulation also has loopholes. It lacks pulse simulation and cannot fully restore the key morphological characteristics of the human body, resulting in poor realism. When performing cardiopulmonary simulated resuscitation operations, the mannequin presents a relatively simple form, making it difficult to restore the various complex scenes in first aid training, which severely limits students' first aid operation experience and greatly affects the final training effect. As a result, when the trained first aid personnel are faced with pre-hospital first aid tasks, they may encounter problems such as being at a loss for response and operating in an irregular manner, and cannot meet actual rescue needs. Summary of the invention

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0027] The present invention provides a pre-hospital emergency training system based on real-time interaction, comprising: a human body model 1, an eye simulation mechanism 2, an oral cavity recognition mechanism 3, a bionic pulse mechanism 4, a cardiopulmonary resuscitation simulation mechanism 5, and a sensing device 6.

[0028] The eye simulation mechanism 2 is arranged in the head of the human model 1. The eye simulation mechanism 2 includes a base 21, two blinking components 22, two bionic eyeballs 23, two transmission components 24, two moving components 25, two bionic pupil components 26, and two photosensitive sensors 27. The two blinking components 22 are both mounted on the base 21. The two bionic eyeballs 23 are both fixedly connected to the base 21. One end of the two transmission components 24 is connected to the two blinking components 22, and the other end is connected to the two moving components 25 respectively. The two bionic pupil components 26 are respectively slidably connected to the two moving components 25. The two photosensitive sensors 27 are both mounted on the base 21.

[0029] like Figure 2-Figure 3 As shown, the base 21 supports the installation of the entire structure so that the eye simulation mechanism 2 can be installed in the head of the human model 1 to simulate the eyeball. The two blinking components 22 are respectively used to blink the upper and lower eyelid bodies. The two bionic eyeballs 23 are made of acrylic plates, which can increase the glossiness of the eyeballs. The two transmission components 24 are respectively fixedly connected to the two bases 21, and the transmission component 24 is composed of two rolling wheels and a belt, so that the driving force generated by the base 21 can be transmitted to the mobile component 25 for use. The two mobile components 25 are used to simulate the effect of the pupil becoming larger and smaller on the bionic pupil component 26. The photosensitive sensor 27 has a highly sensitive light sensing ability. It can sense the intensity changes of the surrounding light in real time, quickly convert the light signal into an electrical signal, and transmit these signals to the control system, thereby regulating the bionic pupil component 26 to simulate the operation mode of the pupil in reality.

[0030] The blinking assembly 22 includes a steering gear 221, a rotating bar 222, a "Y"-shaped rod 223, and two bionic eyelids 224. The steering gear 221 is fixedly mounted on the surface of the base 21, a connecting rod is fixedly mounted on the output end of the steering gear 221, the rotating bar 222 is fixedly connected to the connecting rod, one end of the "Y"-shaped rod 223 is fixedly connected to the rotating bar 222, and the other end is fixedly connected to the bionic eyelid 224. Both bionic eyelids 224 are movably connected to the bionic eyeball 23.

[0031] The servo 1 221 can set a threshold value to adjust the rotation speed, thereby matching the blinking speed of the upper and lower groups of bionic eyelids 224. The rotating bar 222 is fixedly connected to the output end of the servo 1 221. When the servo 1 221 is started, its output end rotates, driving the rotating bar 222 fixedly connected thereto to rotate accordingly. At this time, the "Y"-shaped rod 223 fixedly connected to the rotating bar 222 will operate synchronously, driving the two upper bionic eyelids 224 connected thereto to blink. Similarly, another "Y"-shaped rod 223 will drive the other two corresponding lower bionic eyelids 224 to blink, ultimately achieving the synchronous blinking of the upper and lower groups of eyelids in the eye simulation mechanism 2, simulating the blinking effect.

[0032] The moving assembly 25 includes a connecting rod 251, a sleeve rod 252, a roller 253, a toggle frame 254, and a sliding rod 255. The connecting rod 251 is fixedly connected to the transmission assembly 24, and the sleeve rod 252 is slidably connected to the connecting rod 251. The roller 253 is fixedly connected to one end of the sleeve rod 252. The toggle frame 254 is movably installed on one side of the roller 253. The sliding rod 255 is fixedly connected to the roller 253. A support plate slidably connected to the sliding rod 255 is installed on the surface of the base 21, and an elastic block is fixedly installed on one side of the support plate. Four telescopic rods are fixedly connected to one side of the toggle frame 254, and one end of the four telescopic rods is fixedly connected to the support plate.

[0033] The connecting rod 251 is fixedly connected to the transmission assembly 24 and can rotate under the transmission of the transmission assembly 24, while the sleeve rod 252 forms a limited sliding connection with the connecting rod 251, so that the roller 253 can be driven to rotate under the transmission of the transmission assembly 24, and the roller 253 can be supported to rotate by the installation of the positioning plate. The sliding rod 255 is connected to the roller 253 and can be driven to rotate by the roller 253. A limiting disk is provided at one end of the sliding rod 255, and the limiting disk penetrates one end of the support plate to form a limiting connection, which can block and limit the sliding rod 255 when it moves. One end of the toggle frame 254 is composed of a sleeve ring, so that one side of the sleeve ring forms a movable connection with the roller 253, and the other side can be limited by the support of four telescopic rods, so that when the roller 253 rotates and translates, the toggle frame 254 can be translated. When the toggle frame 254 moves, it will contact the support plate on one side. Since the support plate is equipped with an elastic block, the toggle frame 254 can generate a buffer when it touches the elastic block, thereby reducing the operation vibration between the structures and improving stability.

[0034] A support plate is fixedly installed at one end of the connecting rod 251, and the connecting rod 251 passes through the support plate and is fixedly connected to the transmission assembly 24. Four limit bars are fixedly connected to the surface of the connecting rod 251, and the inner wall of the sleeve rod 252 is provided with four limit grooves movably connected to the limit bars. A slide groove is provided on the surface of the roller 253, and a positioning block movably abutting against the slide groove is fixedly installed on the surface of the base 21.

[0035] The front end of the connecting rod 251 is installed through a support plate and can rotate under the transmission of the transmission assembly 24. The surface of the connecting rod 251 is provided with four limit bars, so that the four limit grooves opened on the inner wall of the sleeve rod 252 are respectively connected with the four limit bars, so that the sleeve rod 252 can move back and forth on the surface of the connecting rod 251 and rotate with the rotation of the connecting rod 251. The surface of the roller 253 is provided with a slide groove, and the positioning block is connected through a bracket, which can just make the positioning block abut against the slide groove, and can be driven to move when the roller 253 rotates as a whole.

[0036] The bionic pupil assembly 26 includes an aperture 261, a lever 262, and a support rod 263. The aperture 261 is fixedly mounted on the bionic eyeball 23. The lever 262 is fixedly connected to the aperture 261. The support rod 263 is fixedly connected to the lever 262. A movable groove slidably connected to the support rod 263 is provided on the surface of the toggle frame 254.

[0037] The diaphragm 261 can simulate the dynamic effect of the pupil becoming larger and smaller, and by setting a lever 262 at the start end of the diaphragm 261, the diaphragm 261 can be opened and closed when the lever 262 is toggled. A sliding bead is installed at one end of the support rod 263, and the sliding bead is located in the movable groove provided on the surface of the toggle frame 254 for movement, so that the lever 262 can produce a limited connection effect. When the toggle frame 254 moves, the lever 262 can be driven to slide in the movable groove, so that the diaphragm 261 can be toggled to open and close, achieving a zoom effect of simulating the pupil.

[0038] like Figure 4 As shown, the oral recognition mechanism 3 includes a simulated trachea body 31 and four Hall sensors 32. The simulated trachea body 31 is used to simulate the trachea of ​​the human model 1. Four Hall sensors 32 are respectively fixedly connected to the surface of the simulated trachea body 31 to detect foreign objects in the simulated trachea body 31. The simulated trachea body 31 is used to simulate the human trachea in the human model 1. By setting Hall sensors 32 around the simulated trachea body 31, a "foreign object monitoring defense line" is formed. In actual first aid, foreign objects such as food residues (such as nut particles, rice lumps), vomit, dentures, loose teeth, and children's accidental inhalation of small objects in the oral cavity, which will block the respiratory tract and cause suffocation. The Hall sensor 32 monitors the changes in the magnetic field and accurately captures the traces of foreign objects in real time. Once the foreign object approaches or contacts, it immediately sends a signal to the system to prompt the rescuer to detect the risk in time.

[0039] like Figure 5-Figure 6 As shown, the bionic pulse mechanism 4 is arranged in the neck of the human model 1 to simulate the pulse beating. The bionic pulse mechanism 4 includes a driving device 41, a mounting frame 42, two piston rods 43, two casings 44, and two mechanical buttons 45. The mounting frame 42 is fixedly mounted on the top of the driving device 41. The two piston rods 43 are fixedly connected to the driving device 41. The two casings 44 are fixedly mounted on the upper surface of the mounting frame 42, and the two piston rods 43 are movably connected to the inside of the two casings 44, and the tops of the two casings 44 are fixedly mounted with mechanical buttons 45.

[0040] The driving device 41 is a driving structure that can drive the two piston columns 43 to move up and down, the mounting frame 42 supports the two piston columns 43 for movement, and the two housings 44 are used to protect the two piston columns 43. A mechanical button 45 is provided on the top of the two piston columns 43 to achieve controllable pulse beats, and the mechanical button 45 is used to identify the position where the user touches the pulse.

[0041] The driving device 41 includes a second steering gear 411, a limit frame 412, a turntable 413, a "T"-shaped movable plate 414, a rotating wheel 415, and a top plate 416. The output end of the second steering gear 411 is fixedly connected with a rotating rod. The limit frame 412 is rotatably mounted on the surface of the rotating rod, and the turntable 413 is fixedly connected to one end of the rotating rod. The limit frame 412 is movably connected to the "T"-shaped movable plate 414. One side of the "T"-shaped movable plate 414 is rotatably connected with two rotating wheels 415. Both rotating wheels 415 are movably abutted against the turntable 413.

[0042] The output end of the servo 2 411 is provided with a rotating rod, and the limiting frame 412 is movably mounted on the rotating rod, while the other end is fixedly supported on the mounting frame 42, so as to achieve the limiting installation of the limiting frame 412 as a whole. The turntable 413 is fixedly mounted on one end of the rotating rod, and can be used to rotate the turntable 413 when the rotating rod rotates. The top of the "T"-shaped movable plate 414 is limitedly connected by the limiting frame 412, so that the two rotating wheels 415 movably mounted on the surface of the "T"-shaped movable plate 414 can be movably abutted on the turntable 413. Therefore, when the turntable 413 rotates, it can be rotatably abutted with the two rotating wheels 415, and when the turntable 413 rotates half a circle, it will drive the "T"-shaped movable plate 414 as a whole to move up and down following the position where the rotating wheels 415 abut against the turntable 413, and then drive the two piston rods 43 to move up and down, so as to achieve the effect of simulating the beating of the pulse.

[0043] like Figure 7 As shown, the cardiopulmonary resuscitation simulation mechanism 5 is arranged in the chest cavity of the human model 1 to simulate the lungs. The cardiopulmonary resuscitation simulation mechanism 5 includes an upper plate 51, a grating 52, a guide post 53, a sleeve 54, a silicone pad 55, an air cylinder 56, and a servo 57. The grating 52 is fixedly connected to the upper plate 51. One end of the guide post 53 is movably abutted against the upper plate 51, and the other end is movably connected to the sleeve 54. The silicone pad 55 is fixedly connected to the top of the sleeve 54. The air cylinder 56 is installed on the lower surface of the upper plate 51.

[0044] A steering gear 3 57 is provided below the upper plate 51, and the steering gear 3 57 can be used to drive the upper plate 51 to achieve controllable automatic chest rise and fall, and the rotation speed of the steering gear 3 57 can be adjusted. A pressure sensor is provided on the upper plate 51, and the pressure sensor is used to identify and judge the position and real-time pressure in the chest compression part. The depth of compression can be monitored in real time through the grating 52. The sleeve 54 and the sleeve 54 ensure the firmness of the mechanism, and the silicone pad 55 is used to buffer the compression impact force. The breathing sound and breathing gas of the model are simulated by the air cylinder 56 pressing the air out to simulate the breathing sound and breathing gas.

[0045] like Figure 1As shown, the head of the human model 1 is equipped with a head plate three-axis sensor 61, which is mainly responsible for accurately sensing the posture changes of the head in three-dimensional space, that is, it can monitor the pitch, yaw and roll of the head in real time. The shoulder sensor component 62 serves as a sensor for the shoulder. In first aid training, the shoulder sensor can detect whether the rescuer's pressing position is accurate. If the pressing position deviates from the shoulder area, the sensor can issue a prompt to ensure that the rescuer operates in the correct position. At the same time, the sensor can measure the force of the pressing. The appropriate pressing force is crucial for effective cardiopulmonary resuscitation. The shoulder sensor can provide force data to help the rescuer adjust the pressing intensity to avoid ineffective resuscitation due to too little force, or damage to the model due to too much force.

[0046] In first aid training, the thigh sensor 63 can capture the bending and extension angles of the thigh. It can be used to analyze whether the trainee's thigh movements are standardized when performing first aid operations. For example, in cardiopulmonary resuscitation operations, the rescuer's thigh posture will affect the body's stability and the transfer of force. The sensor data can be used to determine whether the trainee's operating posture meets the standard. The calf sensor 64 can capture the movement of the calf. For example, when performing cardiopulmonary resuscitation (CPR), the rescuer's calf posture and movement will affect the body's stability and the transfer of force. The calf sensor 64 can record the flexion and extension angles, rotation and other movements of the calf, and analyze whether the rescuer's operation is standardized. In first aid operations, the calf may be subjected to a certain amount of pressure, especially when carrying or supporting the wounded. The pressure film embedded in the side of the calf can monitor the size and distribution of the pressure on the calf in real time. For trainees, pressure data can help them adjust their operating posture to avoid self-injury or operating errors due to excessive pressure. For example, if the pressure film detects that the pressure in a certain part is too high, it may prompt the trainee to adjust the posture to distribute the pressure more evenly.

[0047] By continuously collecting the movement data of the ankle joint during the first aid operation, the ankle infrared sensor 65 can quantitatively analyze the training effect. As the number of training increases, the stability, accuracy and speed of the rescuer's ankle movement can be intuitively reflected by the ankle infrared sensor 65, helping the trainer and coach understand the progress of the training. Based on the data collected by the ankle infrared sensor 65, personalized feedback can be provided to each trainee.

[0048] In the first aid training mannequin 1, the mainboard dual-sensing device 66 can detect changes in the posture of the model's body. For example, when simulating CPR operations, the model's chest compression angle and body tilt angle are crucial to the correctness of the operation. The mainboard dual-sensing device 66 can monitor these angles in real time to ensure that the trainer's operation meets the standards. When simulating CPR operations, the air pressure sensor can measure the pressure on the model's chest. By monitoring the changes in air pressure during compression, it can be determined whether the trainer's compression force is appropriate. If the compression force is too large or too small, the air pressure sensor can send a signal to prompt the trainer to make adjustments to ensure the effectiveness of the CPR operation.

[0049] The arm sensor 67 can monitor the arm movements in real time, including the angle, strength and speed of various movements such as stretching, bending and twisting. These data are fed back to the trainer or the system to help the trainer understand whether his or her movements are standardized and standard so that timely adjustments can be made. For example, in cardiopulmonary resuscitation training, the stretching and pressing movements of the arm during compression can be monitored to ensure that the compression movements meet the requirements.

[0050] like Figure 8 As shown, the shoulder sensor assembly 62 includes a magnet sheet 621 and a Hall sensor 622. The magnet sheet 621 is fixedly connected to the outer skin of the human model 1, and the Hall sensor 622 is fixedly embedded in the inner skin of the human model 1. The electrode patch position is reached through the Hall sensor 622 embedded under the cortex and the magnet sheet 621 embedded on the electrode sheet. When the Hall trigger is on, the patient's electrocardiogram activity can be recorded stably and controllably for a long time, including heart rate, rhythm and other information.

[0051] The working principle of the real-time interactive pre-hospital emergency training model of this embodiment is as follows: when the user taps the model's shoulder, the shoulder sensor component 62 immediately provides the system with feedback on whether the tapping position and strength are correct. When the user uses a light source such as a flashlight to evaluate the pupil state of the model, the light sensor 27 installed in the model's eye can sense the light source and feed back the information to the system, and then the two servos 221 can be started. The two servos 221 drive the two transmission components 24 to drive the two moving components 25, so that the sleeve rod 252 can be movably located on the surface of the connecting rod 251, and drive the roller 253 to rotate. The roller 253 rotates and translates under the action of the positioning block, so that the toggle frame 254 connected at one end drives the support rod 263 to slide in the slide groove provided on the toggle frame 254, so as to achieve the toggle effect of the toggle rod 262, and then the diaphragm 261 can produce a closing and opening effect when it contacts the light source. At the same time, the two servos 221 can respectively drive the two "Y"-shaped rods 223 to blink the upper and lower eyelids of the model, so as to adapt to the different reactions of the model. The bionic pulse mechanism 4 can simulate the pulse beating, and the operation of the driving device 41 will drive the two piston rods 43 to move up and down as a whole, so that when the user presses the mechanical button 45 and the user evaluates the pulse of the model person, it will automatically feedback whether the touch position is correct. If the touch position is correct, the presence or absence of pulse and different pulse frequencies can be set according to the needs of the case. The cardiopulmonary resuscitation simulation mechanism 5 installed on the chest of the model person can drive the upper plate 51 to achieve controllable automatic chest ups and downs by using the steering gear 3 57. The pressure sensor is used to identify and judge the position and real-time pressure in the chest compression part. The depth of compression can be monitored in real time through the grating 52. The silicone pad 55 is used to buffer the impact of the compression, and the breathing sound and breathing gas of the model are simulated by pressing the air out of the air cylinder 56.

[0052] This embodiment, by setting up an eye simulation mechanism 2, a bionic pulse mechanism 4, and a cardiopulmonary resuscitation simulation mechanism 5, can enable the model person to show anthropomorphic physiological reactions according to different first aid scenarios. For example, when simulating eye trauma, the photosensitive sensor 27 simulates the state of the eyeball and eyelid to help students master the assessment of eye injuries. The bionic pulse mechanism 4 beats accurately on demand and can feedback the touch position, thereby cultivating pulse diagnosis capabilities. The controllable automatic rise and fall of the chest is achieved through the servo three 57, and the pressure sensor and grating 52 respectively monitor the pressing position and real-time pressure to restore the cardiopulmonary resuscitation scene in all directions, which can provide students with practical experience in training, help them become familiar with the key points of operation, and improve the success rate of first aid.
