Description

Technical Field

[0001] This application relates to the field of medical training technology, and in particular to a multimodal emergency care teaching device for cardiopulmonary resuscitation (CPR). Background Technology

[0002] Cardiopulmonary resuscitation (CPR) is a series of life-saving measures that improve the chances of survival after cardiac arrest. Currently, public awareness of CPR in my country is very low. Many people are at a loss when faced with a cardiac arrest patient, knowing only how to call 120 (the emergency number in China). As a result, patients often die from prolonged cerebral hypoxia before ambulances arrive.

[0003] Although visual impairment affects their mobility, social interaction, and daily life, visually impaired individuals are in no way inferior to others in other areas of development. They may even surpass sighted individuals in areas such as memory, recognizing people by sound, sound localization, and spatial awareness, and possess greater empathy. Therefore, some visually impaired individuals with intact limbs can also act as "first responders" and participate in necessary rescue efforts after perceiving distress signals in their surroundings.

[0004] Existing mannequins are only suitable for first aid training for able-bodied individuals. Due to poor perception of the outside world caused by visual impairment, visually impaired patients often cannot complete the entire rescue process well, and are even less able to accurately assess the quality of their first aid (such as the quality of chest compressions), thus affecting the success rate of out-of-hospital emergency care for visually impaired patients. Summary of the Invention

[0005] The purpose of this application is to address the problem that visually impaired patients often cannot complete the entire rescue process well due to poor perception of the outside world, which affects the success rate of out-of-hospital emergency care for visually impaired patients. This application provides a multimodal emergency teaching device for cardiopulmonary resuscitation.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A multimodal emergency teaching device for cardiopulmonary resuscitation (CPR) includes a mannequin body. A controller and a positioning component are mounted on one end of the mannequin body. A voice announcer is fixedly connected to one side of the controller. A simulation chamber is formed at one end of the mannequin body. A rubber sheet is fixedly connected to the top of the simulation chamber. A compression box is fixedly connected to one end of the rubber sheet. A U-shaped support frame is fixedly connected to the bottom of the simulation chamber. A support rod is fixedly connected inside the U-shaped support frame. A transmission rod is ball-jointed to the middle section of the support rod. The top of the transmission rod is fixedly connected to the pressing box, and the bottom of the transmission rod is fixedly connected to an impact block. The inner bottom of the U-shaped fixing frame is provided with an installation groove, and the impact block is installed inside the installation groove. Four arc-shaped follower plates are evenly distributed inside the installation groove, and four pressure sensors adapted to the arc-shaped follower plates are evenly fixedly connected to the inner side of the installation groove. A Bluetooth signal transmitter is installed on the top of the pressure sensor. A guide component is installed on one side of the arc-shaped follower plate. The controller is electrically connected to the positioning component and the Bluetooth signal transmitter.

[0008] By adopting the above technical solution, firstly, by setting up a positioning component in conjunction with a controller and a voice announcer, the relative position of the visually impaired patient and the mannequin is easily determined, and the visually impaired patient is guided to move next to the mannequin. Then, by setting up an impact block in conjunction with an arc-shaped follower plate and a pressure sensor, the compression angle of the visually impaired patient is easily determined. Finally, by using a Bluetooth signal transmitter in conjunction with the controller and voice announcer, the visually impaired patient is guided to adjust the compression angle. This facilitates the instruction of the visually impaired patient to perform the correct angle of CPR compressions on the mannequin, effectively improving the success rate of out-of-hospital emergency care for visually impaired patients.

[0009] Furthermore, the positioning component includes an infrared scanner fixedly connected to one end of the simulated human body, and a Bluetooth signal transmitter is installed at one end of the infrared scanner, which is electrically connected to the controller.

[0010] By adopting the above technical solution and using the infrared scanner and Bluetooth signal transmitter four in combination, it is easier to determine the relative position signal between the visually impaired patient and the simulated human body, thus improving the practicality of the device.

[0011] Furthermore, the guiding component includes a pair of storage slots formed inside the mounting slot, with a sliding rod slidably connected inside the storage slot. One end of the sliding rod is fixedly connected to the arc-shaped follower plate, and a guide spring is sleeved around the sliding rod. The guide spring is installed between the arc-shaped follower plate and the controller, and the pressure sensor is installed between the two storage slots.

[0012] By adopting the above technical solution, and by setting up a storage groove in conjunction with a sliding rod and a guide spring, when the arc-shaped follower plate is hit by the impact block, the sliding rod guides the arc-shaped follower plate toward the inner wall of the mounting groove. After the impact block hits the arc-shaped follower plate, the rebound of the guide spring pushes the arc-shaped follower plate out, allowing the arc-shaped follower plate to return to its original position, thereby improving the practicality of the device.

[0013] Furthermore, a chest cavity simulation component is installed inside the compression box. The chest cavity simulation component includes a compression plate that is slidably connected inside the compression box. Ejection springs are fixedly connected to the four corners inside the compression box. The top of the ejection springs is fixedly connected to the compression plate. A depth detection component is installed at the bottom inside the compression box.

[0014] By adopting the above technical solution, the combination of the compression plate and the ejection spring facilitates the simulation of cardiopulmonary resuscitation (CPR) on the mannequin, enabling visually impaired patients to perform the compression and recovery process. Simultaneously, the depth detection component monitors the movement distance of the compression plate by the visually impaired patient, thereby determining whether the compression pressure meets the emergency standards. This facilitates the simulation of CPR on the mannequin, effectively improving the realism of the device.

[0015] Furthermore, the depth detection component includes a detection main board fixedly connected to the bottom of the pressing box, a laser signal receiver fixedly connected to the top of the detection main board, a laser signal transmitter adapted to the laser signal receiver fixedly connected to the bottom of the pressing plate, and the detection main board electrically connected to the controller.

[0016] By adopting the above technical solution, and by setting up the detection motherboard in conjunction with the laser signal receiver and laser signal transmitter, the pressing plate moves along the inner wall of the pressing box while the laser signal receiver receives the laser signal emitted by the laser signal transmitter to determine the moving distance of the pressing plate. At the same time, a voice broadcaster is provided to give voice prompts to visually impaired patients to adjust the pressing pressure, thereby effectively improving the teaching accuracy of the device.

[0017] Furthermore, an arched protective frame is symmetrically fixedly connected to the inner bottom of the pressing box, and the detection motherboard is installed inside the arched protective frame.

[0018] By adopting the above technical solution, the arched protective frame facilitates the protection of the detection motherboard and the laser signal receiver, effectively reducing the possibility of collisions between the laser signal transmitter and the laser signal receiver, and improving the safety of the device.

[0019] Furthermore, one end of the simulated human body is fixedly connected to a shape prosthesis one, and the other end of the simulated human body is symmetrically fixedly connected to a shape prosthesis two.

[0020] By adopting the above technical solution, and by setting up shape prosthesis one and shape prosthesis two, it is easier to help visually impaired patients quickly find the location of the pressure box and then carry out timely rescue, thus improving the practicality of the device.

[0021] Furthermore, multiple high-sensitivity touch sensors are evenly distributed at one end of the simulated human body. A Bluetooth signal transmitter is installed at one end of each high-sensitivity touch sensor. A high-sensitivity touch sensor is fixedly connected to the top of the extrusion plate. A Bluetooth signal transmitter is installed at one end of each high-sensitivity touch sensor. The controller is electrically connected to the Bluetooth signal transmitter and the Bluetooth signal transmitter.

[0022] By adopting the above technical solution, and by setting up the high-sensitivity touch sensor 1 in conjunction with Bluetooth signal transmitter 2, high-sensitivity touch sensor 2, and Bluetooth signal transmitter 3, it is convenient to use a voice broadcaster to broadcast prompts to visually impaired patients when they touch different areas of the mannequin, thereby improving the guidance effect for visually impaired patients.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application firstly uses a positioning component in conjunction with a controller and a voice announcer to facilitate determining the relative position of the visually impaired patient and the mannequin, and guides the visually impaired patient to move next to the mannequin. Then, by using an impact block in conjunction with an arc-shaped follower plate and a pressure sensor, it facilitates determining the compression angle of the visually impaired patient. Finally, by using a Bluetooth signal transmitter in conjunction with the controller and the voice announcer, it guides the visually impaired patient to adjust the compression angle, thereby facilitating the instruction of the visually impaired patient to perform the correct angle of CPR compressions on the mannequin, effectively improving the success rate of out-of-hospital emergency care for visually impaired patients.

[0025] 2. In this application, by setting up a storage groove and using a sliding rod and a guide spring in combination, when the arc-shaped follower plate is hit by the impact block, the sliding rod guides the arc-shaped follower plate toward the inner wall of the mounting groove. After the impact block hits the arc-shaped follower plate, the rebound of the guide spring pushes the arc-shaped follower plate out, so that the arc-shaped follower plate returns to its original position, thereby improving the practicality of the device.

[0026] 3. Firstly, by setting up the compression plate and the ejection spring in combination, it is easy to assist visually impaired patients in completing the simulation of cardiopulmonary resuscitation (CPR) on the mannequin. At the same time, the depth detection component monitors the movement distance of the compression plate when the visually impaired patient presses, thereby determining whether the pressure applied by the visually impaired patient meets the emergency standards. This facilitates the visually impaired patient in completing the CPR simulation on the mannequin and effectively improves the simulation realism of the device. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a multimodal emergency rescue teaching device for cardiopulmonary resuscitation.

[0036] Reference Figures 1-4A multimodal emergency teaching device for cardiopulmonary resuscitation (CPR) includes a mannequin body 1, a controller 2 mounted on one end of the mannequin body 1, and a positioning component 3 located on the other end of the mannequin body 1. A voice announcer 4 is fixedly connected to one side of the controller 2. A simulation chamber 5 is formed at one end of the mannequin body 1. A rubber sheet 6 is fixedly connected to the top of the simulation chamber 5, and a compression box 7 is fixedly connected to one end of the rubber sheet 6. A U-shaped fixing frame 8 is fixedly connected to the bottom of the simulation chamber 5. A support rod 9 is fixedly connected inside the U-shaped fixing frame 8. A transmission rod 10 is ball-jointed to the middle section of the support rod 9. The top of the transmission rod 10 is fixedly connected to the compression box 7, and an impact block 11 is fixedly connected to the bottom of the transmission rod 10. An installation groove 12 is formed in the bottom of the U-shaped fixing frame 8, and the impact block 11 is installed inside the installation groove 12. Four arc-shaped follower plates 13 are evenly distributed inside the groove 12, and four pressure sensors 14 adapted to the arc-shaped follower plates 13 are evenly fixedly connected to the inner side of the groove 12. A Bluetooth signal transmitter 15 is installed on the top of the pressure sensor 14. A guide component 16 is installed on one side of the arc-shaped follower plate 13. The controller 2 is electrically connected to the positioning component 3 and the Bluetooth signal transmitter 15. The four arc-shaped follower plates 13 and the four corresponding pressure sensors 14 and Bluetooth signal transmitters 15 are arranged in the groove 12 in a vertical, horizontal and vertical manner. The impact block 11 is installed inside the groove 12 and abuts against the arc-shaped follower plate 13. The controller 2 is equipped with a signal receiving unit and a signal processing unit for receiving signals, as well as a signal transmitting unit for transmitting signals.

[0037] In use, the positioning component 3 first scans the infrared imaging around the controller 2 and determines the location of the visually impaired patient through infrared imaging. Then, it sends the location information of the visually impaired patient to the controller 2. After receiving the location of the visually impaired patient, the controller 2 sends a broadcast command to the voice broadcaster 4. The voice broadcaster 4 then issues a travel guidance voice to the visually impaired patient based on the relative position of the visually impaired patient and the mannequin 1, guiding the visually impaired patient to move towards the mannequin 1. This assists the visually impaired patient in moving to the side of the mannequin 1. Then, the voice broadcaster 4 broadcasts the first aid procedure voice to guide the visually impaired patient to press their hands to the top of the compression box 7 for cardiopulmonary resuscitation teaching.

[0038] When a visually impaired patient simulates CPR by pressing the compression box 7 with both hands, an angular deviation occurs. This causes the compression box 7 to drive the transmission rod 10 to oscillate along the ball joint with the support rod 9, creating a fulcrum. The transmission rod 10 then causes the impact block 11 to collide with the arc-shaped follower plate 13 inside the mounting groove 12. Simultaneously, the arc-shaped follower plate 13, guided by the guide assembly 16, moves towards the side wall of the mounting groove 12. This causes the arc-shaped follower plate 13 to press against the pressure sensor 14, which then senses a pressure signal and controls the Bluetooth signal transmitter 1. 5. A sensing signal is sent to the controller 2, which in turn sends a voice broadcast command to the voice broadcaster 4 after receiving the sensing signal. The voice broadcaster 4 then broadcasts to the visually impaired patient that the compression direction is incorrect based on which direction the impact block 11 hits the arc-shaped follower plate 13, and guides the visually impaired patient to shift to the correct compression direction. This allows the visually impaired patient to complete the correct compression perpendicular to the length of the support rod 9, thereby facilitating the instruction of the visually impaired patient to perform the correct angle compression for cardiopulmonary resuscitation on the mannequin body 1, and effectively improving the success rate of out-of-hospital emergency care for visually impaired patients.

[0039] Reference Figure 1 and Figure 2 The positioning component 3 includes an infrared scanner 31 fixedly connected to one end of the mannequin body 1. A Bluetooth signal transmitter 32 is installed at one end of the infrared scanner 31 and is electrically connected to the controller 2.

[0040] First, by activating the infrared scanner 31, infrared scanning lines are emitted with the simulated human body 1 as the center. When the infrared scanning lines touch the visually impaired patient, the infrared scanner 31 receives the position information of the visually impaired patient and sends the position signal of the visually impaired patient to the controller 2 through the Bluetooth signal transmitter 32. This facilitates the determination of the relative position between the visually impaired patient and the simulated human body 1, thus improving the practicality of the device.

[0041] Reference Figures 2-4 The guide assembly 16 includes a pair of storage slots 161 formed inside the mounting slot 12. A slide rod 162 is slidably connected inside the storage slot 161. One end of the slide rod 162 is fixedly connected to the arc-shaped follower plate 13, and a guide spring 163 is sleeved around the slide rod 162. The guide spring 163 is installed between the arc-shaped follower plate 13 and the controller 2. The pressure sensor 14 is installed between the two storage slots 161.

[0042] When a visually impaired patient simulates CPR by pressing the compression box 7 and experiences an angular deviation, the compression box 7, in conjunction with the transmission rod 10, causes the impact block 11 to collide with the arc-shaped follower plate 13. Simultaneously, the arc-shaped follower plate 13 pushes the slide rod 162 into the storage groove 161, and the arc-shaped follower plate 13 moves along the length of the slide rod 162 towards the inner wall of the mounting groove 12. At the same time, the arc-shaped follower plate 13 compresses the guide spring 163 along the length of the storage groove 161, causing the guide spring 163 to contract and deform. Then, when the impact block 11 releases its contact with the arc-shaped follower plate 13, the guide spring 163 releases its compression and rebounds along the length of the storage groove 161, pushing the arc-shaped follower plate 13 back to its original position. This facilitates the guidance and repositioning of the arc-shaped follower plate 13 along the length of the storage groove 161, improving the practicality of the device.

[0043] Reference Figure 1 and Figure 3 , Figure 5 The chest cavity simulation component 17 is installed inside the compression box 7. The chest cavity simulation component 17 includes a compression plate 171 that is slidably connected inside the compression box 7. Ejection springs 172 are fixedly connected to the four corners inside the compression box 7. The top of the ejection springs 172 is fixedly connected to the compression plate 171. A depth detection component 174 is installed at the bottom inside the compression box 7. When a visually impaired patient presses the compression box 7, the visually impaired patient's hand presses on the top of the compression plate 171.

[0044] The depth detection component 174 includes a detection motherboard 1741 fixedly connected to the bottom of the pressing box 7. A laser signal receiver 1742 is fixedly connected to the top of the detection motherboard 1741, and a laser signal transmitter 1743 adapted to the laser signal receiver 1742 is fixedly connected to the bottom of the pressing plate 171. The detection motherboard 1741 is electrically connected to the controller 2.

[0045] When in use, when a visually impaired patient presses the compression plate 171 to perform simulated cardiopulmonary resuscitation, the compression plate 171 moves downward along the inner wall of the compression box 7 and compresses the ejector spring 172, causing the ejector spring 172 to contract and deform. Then, when the visually impaired patient releases the pressure, the ejector spring 172 is released from the force and pushes the compression plate 171 upward along the guide direction of the inner wall of the compression box 7, so that the compression plate 171 returns to its original position.

[0046] Simultaneously, as the compression plate 171 moves up and down along the inner wall of the compression box 7, it drives the laser signal transmitter 1743 to move closer to or further away from the ejector spring 172. The ejector spring 172 then receives the laser signal emitted by the laser signal transmitter 1743 to determine the distance the compression plate 171 has moved. The detection motherboard 1741 processes the received signal from the laser signal receiver 1742 and sends a monitoring signal to the controller 2. Simultaneously, the controller 2 sends a voice broadcast command to the voice broadcaster 4 based on the monitoring signal collected by the detection motherboard 1741. The voice broadcaster 4 then verbally informs the visually impaired patient that the compression pressure needs to be adjusted. This facilitates monitoring whether the compression pressure of the visually impaired patient meets the emergency requirements and assists the visually impaired patient in performing cardiopulmonary resuscitation on the mannequin 1, effectively improving the simulation realism of the device.

[0047] Reference Figure 3 and Figure 5 An arched protective frame 18 is symmetrically fixed to the bottom of the pressing box 7, and the detection main board 1741 is installed inside the arched protective frame 18.

[0048] When in use, when the pressing plate 171 drives the laser signal transmitter 1743 to move downward along the inner wall of the pressing box 7, the arched protective frame 18 forms a resistance against the pressing plate 171, thereby effectively preventing the pressing plate 171 from driving the laser signal transmitter 1743 to collide with the laser signal receiver 1742 and improving the safety of the device.

[0049] Reference Figure 1 and Figure 2 One end of the simulated human body 1 is fixedly connected to a shape prosthesis 19, and the other end of the simulated human body 1 is symmetrically fixedly connected to a shape prosthesis 20.

[0050] When in use, when the voice broadcaster 4 guides the visually impaired patient to move to the side of the mannequin 1, the presence of prosthetic shape 19 and prosthetic shape 20 provides a clearer guide for the visually impaired patient, helping them to quickly find the correct location of the pressing box 7. For example, by touching the two prosthetic shapes 20, the midpoint of the line connecting the two prosthetic shapes 20 is the location of the pressing box 7.

[0051] Reference Figure 1 and Figure 3 , Figure 5Multiple high-sensitivity touch sensors 21 are evenly distributed at one end of the simulated human body 1. A Bluetooth signal transmitter 22 is installed at one end of the high-sensitivity touch sensor 21. A high-sensitivity touch sensor 23 is fixedly connected to the top of the extrusion plate 171. A Bluetooth signal transmitter 24 is installed at one end of the high-sensitivity touch sensor 23. The controller 2 is electrically connected to the Bluetooth signal transmitter 22 and the Bluetooth signal transmitter 24.

[0052] In use, when a visually impaired patient touches the limbs or abdomen of the mannequin 1, the highly sensitive touch sensor 21 receives the touch signal and transmits it to the controller 2 via the Bluetooth transmitter 22. The controller 2 then sends a voice broadcast command to the voice broadcaster 4, which in turn broadcasts the specific joint of the mannequin 1 that was touched to guide the patient. When the patient touches the compression plate 171, the highly sensitive touch sensor 23 transmits the signal via the Bluetooth transmitter... The third component 24 sends a touch signal to the controller 2, causing the controller 2 to control the voice broadcaster 4 to broadcast the best rescue location to the visually impaired patient. At the same time, the controller 2 controls the voice broadcaster 4 to stop broadcasting the touch signal detected by the high-sensitivity touch sensor 21. When the visually impaired patient's hand leaves the surface of the compression plate 171, the controller 2 controls the voice broadcaster 4 to broadcast the touch signal detected by the high-sensitivity touch sensor 21 again. This facilitates the voice broadcaster 4 to provide voice prompts to the visually impaired patient about the touch location, thereby improving the guidance effect for the visually impaired patient.

[0053] Working principle: First, the positioning component 3 scans the infrared imaging around the controller 2 and determines the position of the visually impaired patient through infrared imaging. Then, it sends the position information of the visually impaired patient to the controller 2. After receiving the position of the visually impaired patient, the controller 2 sends a broadcast command to the voice broadcaster 4. The voice broadcaster 4 then issues a travel guidance voice to the visually impaired patient based on the relative position of the visually impaired patient and the mannequin 1, so as to guide the visually impaired patient to move towards the mannequin 1. This helps the visually impaired patient move to the side of the mannequin 1. Then, the voice broadcaster 4 broadcasts the emergency procedure voice to guide the visually impaired patient to press their hand to the top of the compression plate 171.

[0054] Then, the compression plate 171 moves downward along the inner wall of the compression box 7 and compresses the ejector spring 172, causing the ejector spring 172 to contract and deform. Then, when the visually impaired patient releases the pressure of their hand, the ejector spring 172 is released from the force and pushes the compression plate 171 upward along the guide direction of the inner wall of the compression box 7, so that the compression plate 171 returns to its original position, thereby assisting the visually impaired patient in completing the cardiopulmonary resuscitation simulation of the mannequin body 1.

[0055] Next, when the visually impaired patient simulates cardiopulmonary resuscitation by pressing the compression box 7 with both hands and the angle deviates, the compression box 7 causes the transmission rod 10 to swing along the ball joint with the support rod 9 as the fulcrum. This causes the transmission rod 10 to drive the impact block 11 to collide with the arc-shaped follower plate 13 inside the mounting groove 12. At the same time, the arc-shaped follower plate 13 pushes the slide rod 162 into the inside of the storage groove 161. The arc-shaped follower plate 13 moves closer to the inner wall of the mounting groove 12 along the length of the slide rod 162. Simultaneously, the arc-shaped follower plate 13 compresses the guide spring 163 along the length of the storage groove 161, causing the guide spring 163 to contract and deform.

[0056] Simultaneously, the curved follower plate 13 moves towards the side wall of the mounting groove 12 under the guidance of the guide component 16, thereby causing the curved follower plate 13 to press against the pressure sensor 14. The pressure sensor 14 senses the pressure signal and controls the Bluetooth signal transmitter 15 to send a sensing signal to the controller 2. After receiving the sensing signal, the controller 2 sends a voice broadcast command to the voice broadcaster 4. The voice broadcaster 4 then broadcasts to the visually impaired patient that the pressing direction is incorrect, based on which direction the impact block 11 struck the curved follower plate 13. It guides visually impaired patients to shift in the correct pressing direction, enabling them to complete the correct pressing perpendicular to the length of the support rod 9. Then, when the impact block 11 releases its contact with the arc-shaped follower plate 13, the guide spring 163 releases its compression and rebounds along the length of the receiving groove 161, pushing out the arc-shaped follower plate 13 and moving it back to its original position. This facilitates the guidance of visually impaired patients to complete the correct angle of CPR instruction on the mannequin body 1, effectively improving the success rate of out-of-hospital emergency care for visually impaired patients.
