Description

Technical Field

[0001] The present invention relates to the technical field of Heimlich teaching aids, and particularly relates to an electronic Heimlich teaching aid. Background Art

[0002] The Heimlich maneuver is a first-aid method specifically used to solve airway foreign body asphyxiation. It was invented by Professor Heimlich, an American doctor. In practice, traditional first-aid methods, such as patting the patient's back or inserting fingers into the oral pharynx to remove foreign bodies, are often ineffective and may even cause the foreign body to penetrate deeper into the respiratory tract. Therefore, the emergence of the Heimlich maneuver provides a more effective and safe solution for such emergencies. Heimlich manikins are designed to meet the training needs of first-aid skills and knowledge. These manikins are designed very realistically and can simulate various situations of airway foreign body asphyxiation, enabling trainees to practice in a safe environment and thus master the correct first-aid skills.

[0003] Most of the Heimlich manikins on the market are pure model designs. Although they can simulate basic first-aid scenarios, there are obvious limitations in the training process. First, regarding whether the user's operation actions are standard, it usually depends only on the naked-eye judgment of the training teacher. This subjective judgment method is not only easily affected by personal experience and cognitive biases, but also difficult to ensure the consistency and accuracy of the evaluation. Second, there is also a lack of an objective evaluation standard for whether the operation force is sufficient. Excessive or insufficient force may affect the first-aid effect, and the lack of a quantitative scoring mechanism makes it difficult to effectively solve this problem. Summary of the Invention

[0004] Based on this, in view of the above technical problems, the present invention adopts the following technical solutions: An electronic Heimlich teaching aid, comprising: A vest main body, on the back of the vest main body, there is a rear patting area, a pressure sensor is installed at the rear patting area, and a front pressing area is provided at the front of the vest main body; A simulation mechanism, the simulation mechanism includes a simulated trachea installed at the front of the vest main body, a pressing airbag connected to the bottom of the simulated trachea, and a simulated blocking ball placed in the simulated trachea. A pressure sensor is installed in the inner cavity of the pressing airbag, and the pressing airbag corresponds to the position of the front pressing area; An intelligent simulator, the intelligent simulator is installed in the pressing airbag, and the intelligent simulator is provided with a detection module, a processing module, a power module, and a communication module.

[0005] As a preferred embodiment of the electronic Heimlich teaching aid provided by the present invention, the simulated trachea is made of a transparent material. The pressing airbag is placed inside the vest body. The upper half of the simulated trachea extends to the outside of the vest body, and the lower half of the simulated trachea extends to the inside of the vest body and is connected to the pressing airbag. The pressing airbag is placed on the inner wall of the vest body. When impacting the front pressing area, the pressing airbag is simultaneously impacted. The upper part of the simulated trachea is exposed for easy observation and can also synchronously simulate the position of the trachea.

[0006] As a preferred embodiment of the electronic Heimlich teaching aid provided by the present invention, a partition plate is installed at the upper end of the inner cavity of the pressing airbag. The partition plate is respectively provided with an air port one and a through hole. The bottom of the simulated trachea is provided with a tracheal port corresponding to the air port one. A one-way valve one is installed between the tracheal port and the air port one, and the one-way valve one is used to limit the upward flow of gas. A through hole corresponding to the air port two is provided on the outer wall of the pressing airbag. A one-way valve two is installed between the through hole and the air port two, and the one-way valve two is used to limit the downward flow of gas. By squeezing the pressing airbag, the gas inside it flows through the air port one and into the tracheal port through the connecting pipe one, and then enters the simulated trachea to push the simulated blocking ball. And when the impact on the pressing airbag stops, the pressing airbag resets, and the external gas flows through the through hole and into the air port two through the connecting pipe two to inflate the inner cavity of the pressing airbag, inflating the pressing airbag cyclically, gradually increasing the pressure inside the pressing airbag, which is convenient for detecting the change of the pressure inside the pressing airbag by the pressure sensor, so as to facilitate judging the impact strength and frequency of the abdominal thrust method.

[0007] As a preferred embodiment of the electronic Heimlich teaching aid provided by the present invention, a connecting pipe one is arranged between the tracheal port and the air port one, and the one-way valve one is installed in the connecting pipe one. A connecting pipe two is arranged between the through hole and the air port two, and the one-way valve two is installed in the connecting pipe two. The connecting pipe two and the connecting pipe one are connected in series through a connecting rod. The connecting pipe one is installed at the output end of the telescopic member, and the telescopic member is installed on the partition plate. The position movement of the connecting pipe two and the connecting pipe one can be controlled by the telescopic member. When the connecting pipe two is misaligned with the through hole and the air port two, the external gas can quickly enter the pressing airbag. After the simulation is completed, it is convenient to inflate and reset the inner cavity of the pressing airbag.

[0008] As a preferred embodiment of the electronic Heimlich teaching aid provided by the present invention, a proximity switch I corresponding to the second docking pipe is installed on the partition plate.

A guide pipe is connected to the locking ring. A balance port is opened at the top of the pressing airbag. A check valve III is installed at the balance port. The check valve III is used to limit the flow of gas from top to bottom. By providing the balance port and the check valve III, when it is necessary to press the pressing airbag multiple times to inflate the locking ring, when the pressing airbag is released, the outside gas enters the pressing airbag through the balance port and the first air port, completing the inflation of the inner cavity of the pressing airbag. A valve body is provided at the guide pipe, which is convenient to keep the internal air pressure of the locking ring by closing the valve body after the locking ring is inflated.

The position of the simulation plug ball is limited by the two limiting net plates, and the simulation plug ball can be locked in the simulation trachea, reducing the situation of pollution and loss of the simulation plug ball. When the simulation plug ball moves to the upper limiting net plate of the simulation trachea, at this time, the pressure relief port will communicate with the inner cavity of the simulation trachea and the inner cavity of the pressing airbag, so as to simulate the situation of the simulation plug ball being discharged.

[0012] As a preferred embodiment of the electronic Heimlich teaching aid provided by the present invention, the simulation plug ball is made of rubber material. The simulation plug ball is spherical in structure. The outer ring of the simulation plug ball abuts against the inner wall of the simulation trachea, so that the simulation plug ball can better fit the inner wall of the simulation trachea and improve the sealing effect between the two.

[0019] As described in the background art, the lack of a quantitative scoring mechanism in the existing Heimlich simulation on the market makes it difficult to effectively solve this problem.

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Embodiment

[0025] Please refer to Figures 1-7 , an electronic Heimlich teaching aid, including a vest main body 1, a simulation mechanism and an intelligent simulator 10; a rear slapping area 2 is provided on the back of the vest main body 1, a pressure sensor 3 is installed at the rear slapping area 2, and a front pressing area 6 is provided on the front of the vest main body 1. By setting the rear slapping area 2 to locate the position of the back slapping method and using the front pressing area 6 to locate the position of the abdominal thrust method, it is convenient for students and teachers to intuitively judge whether the operation is standard.

[0026] In addition, please refer to Figure 3 and Figure 4 , the simulation mechanism includes a simulated trachea 4 installed on the front of the vest main body 1, a pressing airbag 8 connected to the bottom of the simulated trachea 4, and a simulated plug ball 5 placed in the simulated trachea 4. A pressure sensor 9 is installed in the inner cavity of the pressing airbag 8. The pressing airbag 8 corresponds to the position of the front pressing area 6. By squeezing the pressing airbag 8, the gas inside it enters the simulated trachea 4 and pushes the simulated plug ball 5 in the simulated trachea 4, thereby simulating the situation where the patient's trachea is blocked by a foreign object, and the state of the simulated plug ball 5 being discharged can be used to judge the first aid skill level of the user, and the pressure sensor 9 is set to detect the force of each impact of the user and judge the state of the simulated plug ball 5.

[0027] It is worth mentioning that, please refer to Figures 4-7, the intelligent simulator 10 is installed in the pressing airbag 8. The intelligent simulator 10 is provided with a detection module, a processing module, a power module and a communication module. The detection module is respectively connected to the processing module, the pressure sensor 3 and the air pressure sensor 9 by signals. The processing module is respectively connected to the power module and the communication module by signals. The communication module is wirelessly connected to a display screen assembly, and the display screen assembly can be an electronic device such as a tablet, a mobile phone or a computer, which is convenient for the teaching teacher to intuitively view the analysis data. The power module supplies power to the electronic components of the whole teaching aid, and the power module can adopt the scheme of disposable batteries. 4 replaceable No. 5 batteries are used as the power source. Due to the low-power consumption property of the device, under normal use conditions, after replacing the battery once, the service time can reach more than 4 months. And we also equipped with a battery switch, which can turn off the power switch when the device is not used for a long time, further reducing the power consumption.

[0028] When the trainee performs a simulation operation, the vest main body 1 is sleeved on the user to provide a teaching experience for him. The trainee pats the back area of the vest main body 1 by the back percussion method. At this time, the pressure sensor 3 sends the detected pressure data to the detection module, and the detection module sends the received pressure data to the processing module. The processing module analyzes the number of pats and the strength of the trainee's back percussion method according to the pressure data, and sends the analysis data to the display screen assembly through the communication module, which is convenient for the teaching teacher to judge; when the trainee performs the abdominal thrust method on the front pressing area 6, the pressing airbag 8 will be impacted, and the air pressure sensor 9 will detect the air pressure data in the pressing airbag 8 and send it to the detection module. The detection module sends the air pressure data to the processing module, and the processing module analyzes the air pressure data of the air pressure sensor 9 to obtain the impact strength and frequency of the trainee's abdominal thrust method, and sends the analysis data to the display screen assembly through the communication module, which is convenient for the teaching teacher to judge. And when the simulated ball 5 is pushed away from the simulated trachea 4 by air pressure, the internal air pressure of the pressing airbag 8 will drop to the normal pressure range. At this time, the processing module analyzes the air pressure data of the air pressure sensor 9 and judges that the air pressure data of the air pressure sensor 9 drops to the normal pressure value. At this time, the processing module judges that the simulated ball 5 has been separated from the simulated trachea 4, and the trainee has successfully completed the first aid, and sends the judgment result to the display screen assembly through the communication module to remind the teaching teacher to judge the first aid skill in time, making the evaluation result more reliable and helping to accurately measure the first aid skill level of the user.

[0029] The communication module supports Bluetooth communication and wireless Wi-Fi communication, which is convenient for the teaching teacher to hold the display screen assembly and watch at multiple positions in the classroom to guide the trainee in time.

[0030] In addition, the simulated trachea 4 is made of a transparent material, which facilitates observing the position of the simulated blocking ball 5 through the simulated trachea 4, making the teaching process more intuitive. The pressing airbag 8 is placed inside the vest main body 1. The upper half of the simulated trachea 4 extends to the outside of the vest main body 1, and the lower half of the simulated trachea 4 extends to the inside of the vest main body 1 and is connected to the pressing airbag 8. The pressing airbag 8 is placed on the inner wall of the vest main body 1. When impacting the front pressing area 6, the pressing airbag 8 is simultaneously impacted. The upper part of the simulated trachea 4 is exposed for easy observation, and the position of the trachea can also be simulated synchronously.

[0031] It is worth mentioning that a partition plate 11 is installed at the upper end of the inner cavity of the pressing airbag 8. The partition plate 11 is respectively provided with an air port 14 and a through hole 15. The bottom of the simulated trachea 4 is provided with a trachea port 13 corresponding to the air port 14. A check valve 1 is installed between the trachea port 13 and the air port 14 to limit the upward flow of gas. The outer wall of the pressing airbag 8 is provided with a through hole 15 corresponding to the air port 16. A check valve 2 is installed between the through hole 15 and the air port 16 to limit the downward flow of gas. A connecting pipe 17 is arranged between the trachea port 13 and the air port 14, and the check valve 1 is installed in the connecting pipe 17. A connecting pipe 18 is arranged between the through hole 15 and the air port 16, and the check valve 2 is installed in the connecting pipe 18. The connecting pipe 18 and the connecting pipe 17 are connected in series through a connecting rod. The connecting pipe 17 is installed at the output end of the telescopic member 12, and the telescopic member 12 is installed on the partition plate 11. By squeezing the pressing airbag 8, the gas inside it flows through the air port 14, through the connecting pipe 17 and into the trachea port 13, and then enters the simulated trachea 4 to push the simulated blocking ball 5. And when the impact on the pressing airbag 8 stops, the pressing airbag 8 resets, and the external gas flows through the through hole 15, through the connecting pipe 18 and into the air port 16 to inflate the inner cavity of the pressing airbag 8, inflating the pressing airbag 8 cyclically, gradually increasing the pressure inside the pressing airbag 8, facilitating detecting the change of the pressure inside the pressing airbag 8 through the pressure sensor 9, so as to facilitate judging the impact strength and frequency of the abdominal thrust method. And through the telescopic member 12, the position movement of the connecting pipe 18 and the connecting pipe 17 can be controlled, as Figure 7 shown, when the connecting pipe 18 is misaligned with the through hole 15 and the air port 16, the external gas can quickly enter the pressing airbag 8, and after the simulation is completed, it is convenient to inflate and reset the inner cavity of the pressing airbag 8. Embodiment

[0032] Further optimize the electronic Heimlich teaching aid provided in the first embodiment. Different from the first embodiment, please refer to Figures 7-9, a proximity switch one 19 corresponding to the docking pipe two 18 is installed on the partition plate 11. On the side of the proximity switch one 19 away from the telescopic member 12, a proximity switch two 20 corresponding to the docking pipe two 18 is installed. The proximity switch two 20 and the proximity switch one 19 can detect the position of the docking pipe two 18. When the docking pipe two 18 moves to the proximity switch two 20, the docking pipe one 17 will move between the through hole 15 and the air port two 16, so as to dock with it. A regulation module is also set on the intelligent simulator 10. The regulation module is respectively signal-connected to the processing module and the telescopic member 12. The detection module is respectively signal-connected to the proximity switch one 19 and the proximity switch two 20. A locking ring 7 with a hollow structure is sleeved outside the simulation air pipe 4. A guide air pipe 24 is connected to the locking ring 7. A balance port 21 is opened at the top of the pressing air bag 8. A check valve three is installed at the balance port 21 to limit the flow of gas from top to bottom. Since the blockage conditions of each patient are different, in order to improve the simulation authenticity, by setting the locking ring 7 and inflating the locking ring 7 to increase the pressure on the simulation air pipe 4, the locking degree of the simulation plug ball 5 is adjusted. When the locking ring 7 needs to be inflated, at this time, the processing module sends a simulation signal to the regulation module. After receiving the simulation signal, the regulation module controls the telescopic member 12 to work. At this time, the telescopic member 12 pushes the docking pipe two 18 and the docking pipe one 17 to move synchronously. When the proximity switch two 20 detects that the docking pipe two 18 moves to this position, the proximity switch two 20 sends the detected position signal to the detection module. The detection module sends the position signal to the processing module. The processing module judges that the docking pipe two 18 moves to the proximity switch two 20, and at the same time, the corresponding docking pipe one 17 moves between the through hole 15 and the air port two 16. The processing module sends a regulation completed signal to the regulation module. The regulation module controls the telescopic member 12 to stop working. At this time, the 27 on the locking ring 7 is inserted into the opening of the through hole 15. In this state, by pressing the pressing air bag 8, the gas inside it flows through the air port two 16, through the docking pipe one 17 and into the through hole 15, and is inflated into the locking ring 7 through the guide air pipe 24, so as to realize the introduction of gas into the locking ring 7, increase the pressure of the locking ring 7, and judge the internal air pressure of the locking ring 7 through the air pressure sensor 9, which is convenient for precise control. Thus, the pressing air bag 8 is used to press the locking ring 7 to simulate the first aid scenarios under different conditions to meet different training needs.

[0033] In addition, by setting the balance port 21 and the check valve three, when the pressing air bag 8 needs to be pressed multiple times to inflate the locking ring 7, when the pressing air bag 8 is released, the outside air enters the pressing air bag 8 through the balance port 21 and the air port one 14 to complete the inflation of the inner cavity of the pressing air bag 8, and a valve body is set at the guide air pipe 24 to facilitate maintaining the internal air pressure of the locking ring 7 by closing the valve body after the locking ring 7 is inflated.

[0034] In this embodiment, the locking ring 7 is made of rubber. The locking ring 7 is sleeved above the initial position of the simulated plug ball 5 to lock the initial position of the simulated plug ball 5, simulating different first aid situations. A pressure relief port 23 is provided on the upper side wall of the upper end of the simulated trachea 4. Limiting net plates 22 are fixed inside the simulated trachea 4 above the pressure relief port 23 and below the initial position of the simulated plug ball 5. The position of the simulated plug ball 5 is limited by the two limiting net plates 22, so that the simulated plug ball 5 can be locked in the simulated trachea 4, reducing the situation of pollution and loss of the simulated plug ball 5. When the simulated plug ball 5 moves to the limiting net plate 22 at the upper end of the simulated trachea 4, at this time, the pressure relief port 23 will communicate with the inner cavity of the simulated trachea 4 and the inner cavity of the pressing air bag 8, thereby simulating the situation of the simulated plug ball 5 being discharged.

[0035] Preferably, the simulated plug ball 5 is made of rubber. The simulated plug ball 5 is spherical in structure. The outer ring of the simulated plug ball 5 abuts against the inner wall of the simulated trachea 4, so that the simulated plug ball 5 can better fit the inner wall of the simulated trachea 4 and improve the sealing effect between the two.

[0036] Electronic operation can quantify the operation actions, making the operation evaluation in the training process more objective and fair. Through the analysis of precise sensors and processing modules, the teaching aid can record and analyze the operation actions and forces of the user in real time, avoiding the subjectivity and uncertainty of traditional visual evaluation. This makes the evaluation results more reliable and helps to accurately measure the first aid skill level of the user. During the training process, the teaching teacher and the teaching aid can cooperate to immediately provide feedback on the standardization of the actions and whether the force is sufficient, enabling the user to immediately adjust their operation methods. This immediate feedback mechanism helps to accelerate the learning process, reduce the repetition of incorrect operations, and enhance the training effect.

[0037] The electronic teaching aid also has stronger flexibility and customizability. By adjusting the parameters and settings of the teaching aid, first aid scenarios under different conditions can be simulated to meet different training needs. At the same time, the teaching aid can also be intelligently adjusted according to the learning progress and skill level of the user to provide a personalized training experience. There has been a substantial improvement in the detection accuracy. Moreover, the production steps of the teaching aid are simplified, further reducing the production cost of the teaching aid.
