[0002] The Heimlich first-aid method is a key method for removing airway foreign body obstruction, and its operation accuracy (such as pressing position, force and direction) is directly related to the success rate of treatment.
[0003] Limitations of traditional simulation mannequin models: existing training relies on passive simulation mannequins, which have simple internal structures and cannot truly simulate the dynamic physiological processes of diaphragmatic elevation and lung gas discharge of foreign bodies when the abdomen is stressed. Although some training devices with sensing functions have emerged, such as detecting operation data through pressure sensors or ultrasonic sensors, their feedback methods are often limited to simple indicator lights or numerical displays, making the training process dull and lacking in immersion. Existing teaching aids have concentrated functions, such as focusing on angle adjustment of the mannequin torso, but the training scenarios are isolated and cannot effectively restore the sense of urgency, team cooperation requirements, and various physiological reactions that may occur in the emergency scene. This leads to the problem that the emergency decision-making ability and team coordination ability of students cannot be effectively exercised. SUMMARY
[0004] In view of the above or the problem that existing technology lacks realism and cannot achieve real-time interaction, the present application is proposed.
[0005] Therefore, the purpose of the present application is to provide a Heimlich lifesaving training waistcoat and training system, which includes a waistcoat, the side wall of the waistcoat is provided with an abdominal module, the upper part of the abdominal module is provided with an immersion piece, the side wall of the waistcoat is provided with a back module; the abdominal module includes an air bag arranged on the side wall of the waistcoat and an airway arranged on the upper part of the air bag; the immersion piece includes an output pipe arranged on the upper part of the air bag, the end of the output pipe is provided with a one-way box for indirect ventilation, the side wall of the one-way box is provided with a three-way pipe, the end of the three-way pipe is provided with a tightening air bag for simulating muscle tension; the lower part of the tightening air bag is provided with a limiting air bag for adapting to different sizes of blockage.

[0008] As a preferred embodiment of the Heimlich maneuver training vest and training system of the present invention, the inner wall of the airway is provided with foam balls.
[0009] As a preferred embodiment of the Heimlich maneuver training vest and training system of the present invention, the immersion component further includes a first connecting tube and a T-shaped groove. The first connecting tube is disposed at the end of the output tube, the T-shaped groove is opened on the inner wall of the one-way box, the inner wall of the T-shaped groove is provided with a fiber ring and a closed ball, and the end of the T-shaped groove is provided with a second connecting tube.

Detailed Implementation
[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0033] Example 1, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 This is the first embodiment of the present invention, which provides a Heimlich maneuver training vest that enhances the realism of immersive training scenarios. It includes a vest 1, an abdominal module 2 on the side wall of the vest 1, an immersive component 3 on the upper part of the abdominal module 2, and a back module 4 on the side wall of the vest 1; wherein...
[0034] The abdominal module 2 includes an air bladder 21 disposed on the side wall of the vest 1, an airway 24 disposed on the upper part of the air bladder 21; and,
[0035] The immersion component 3 includes an output tube 31 disposed on the upper part of the airbag 21, a one-way box 32 for intermittent ventilation disposed at the end of the output tube 31, a three-way tube 33 disposed on the side wall of the one-way box 32, and a tightening airbag 332 for simulating muscle tension disposed at the end of the three-way tube 33; and,
[0036] The lower part of the tightening airbag 332 is provided with a limiting airbag 341 for adapting to blockages of different sizes;
[0037] Furthermore, the abdominal module 2 is disposed on the side wall of the vest 1, and the immersion component 3 is disposed on the opposite side of the abdominal module 2. The abdominal module 2 and the back module 4 are covered in the front and back cavities of the vest 1, and the two modules are electrically connected. When the vest 1 is worn on a real person, the two modules fit tightly against the abdomen and back of the human body. The airbag 21 is made of a relatively hard rubber, and the airway 24 is inserted into the upper inner wall of the airbag 21. The airbag 21 is made of a head and face material or a translucent light-conducting material. An output tube 31 is installed on the upper part of the airbag 21. The inner wall of the output tube 31 is connected to the inner wall of the airbag 21. The output tube 31 is connected to the one-way box 32 through a pipe. The one-way box 32 is connected to the input end of the three-way tube 33. The two output ends of the three-way tube 33 are respectively connected to a tightening airbag 332 through pipes. 334 is disposed between the airbag 21 and the airway 24.
[0038] Specifically, an abdominal pressure sensor 211 is provided on the side wall of the airbag 21, a first angle sensor 212 and a second angle sensor 213 are provided on the inner wall of the airbag 21, a main control PCB 22 is provided at the lower part of the second angle sensor 213, and a buzzer 221 is provided on the side wall of the main control PCB 22.
[0039] Furthermore, the abdominal pressure sensor 211 is fixedly installed on the side wall of the airbag 21, the first angle sensor 212 is fixedly installed on the inner wall of the airbag 21 and corresponds to the position of the abdominal pressure sensor 211 on the outer wall, the installation position of the second angle sensor 213 is horizontal with the first angle sensor 212 and connected to the inner wall of the airbag 21, the side wall of the main control PCB 22 is fixedly connected to the inner wall of the airbag 21, and the side wall of the three-way pipe 33 of the main control PCB 22 is electrically connected to the buzzer 221.
[0040] Specifically, the side wall of the main control PCB 22 is provided with a male wire 222, the upper part of the airbag 21 is provided with an infrared sensor 23, the side wall of the infrared sensor 23 is provided with an LED dual-color light 231, and the inner wall of the airway 24 is provided with a foam ball 241.
[0041] Furthermore, the male connector 222 is electrically connected to the buzzer 221, the infrared sensor 23 is located at the lower part of the foam ball 241 and is fixedly connected to the upper inner wall of the airbag 21, the LED dual-color light 231 is located on the inner wall of the airway 24 and is electrically connected to the infrared sensor 23, and the foam ball 241 is located on the inner wall of the tightening airbag 332 and is in contact with it.
[0042] The procedure is as follows: First, put on the vest 1 and place it on the training surrogate or mannequin. Then, insert the foam ball 241 into the top opening of the airway 24. Observe the color of the LED dual-color light 231. The red light will light up as a warning when there is a foreign object obstruction, and the green light will light up when the obstruction is relieved. The light can be observed from the outside through the airway. Then, perform the Heimlich maneuver to compress the air bag 21.
[0043] At this time, the airbag 21 is pressed and the gas inside rises along the inner wall of the airbag 21 to the inner wall of the air passage 24. The air pressure pushes the foam ball 241 on the inner wall of the air passage 24 upwards along the inner wall of the air passage 24. At the same time, some gas is input along the inner wall of the output pipe 31 to the inner wall of the first connecting pipe 311. Then, it enters the T-shaped groove 321 opened in the one-way box 32 along the inner wall of the first connecting pipe 311. The sealing ball 323 rises along the inner wall of the T-shaped groove 321. When it rises to the other end of the T-shaped groove 321, the gas enters the inner wall of the second connecting pipe 324 and then enters the inner wall of the three-way pipe 33.
[0044] At this time, since the three-way pipe 33 has two output ends, the gas enters the inner wall of the tightening airbag 332 along the connected branch pipe 331. The tightening airbag 332 expands due to the influx of gas, which squeezes the outer wall of the airway 24.
[0045] In the above operation procedure: the expansion of the tightening airbag 332 compresses the airway 24, simulating the human body's breathing being restricted by an obstruction. Simultaneously, during the Heimlich maneuver, due to abdominal compression, the patient physiologically attempts to inhale air, but is unable to do so because of the obstruction, causing muscle tension and changes in the airway that prevent the obstruction from being expelled. The expansion of the tightening airbag 332 simulates the physiological behavior of the human body during the Heimlich maneuver, enhancing the realism of the immersive training scenario.
[0046] Example 2, refer to Figure 3 , Figure 8 and Figure 9 This is the second embodiment of the present invention. Unlike the previous embodiment, it realizes the training of real-time detection data of the Heimlich maneuver and provides real-time guidance.
[0047] Specifically, the immersion component 3 also includes a first connecting tube 311 and a T-shaped groove 321. The first connecting tube 311 is disposed at the end of the output tube 31. The T-shaped groove 321 is opened on the inner wall of the one-way box 32. The inner wall of the T-shaped groove 321 is provided with a fiber ring 322 and a closed ball 323. The end of the T-shaped groove 321 is provided with a second connecting tube 324.
[0048] Furthermore, the bottom end of the first connecting tube 311 is fixedly connected to the top end of the output tube 31 and is in communication with each other. The top surface of the first connecting tube 311 is fixedly connected to the bottom surface of the one-way box 32 and is in communication with the inner wall of the T-shaped groove 321 opened in the inner wall of the one-way box 32. The inner wall of the T-shaped groove 321 is provided with two fiber rings 322, and a closed ball 323 is provided between the two fiber rings 322. The closed ball 323 is in contact with the fiber ring 322 near the first connecting tube 311. The side wall of the infrared sensor 23 is fixedly connected to the end face of the second connecting tube 324, and the inner wall of the second connecting tube 324 is in communication with the inner wall of the infrared sensor 23.
[0049] Specifically, the end of the three-way tube 33 is provided with a branch tube 331, the outer wall of the limiting airbag 341 is provided with a fixing tube 34, the outer wall of the fixing tube 34 is provided with a connecting tube 342, and the end of the connecting tube 342 is provided with a sealing plug 343.
[0050] Furthermore, the other end of the second connecting tube 324 is fixedly connected to the input end of the three-way tube 33 and their inner walls are connected. The two output ends of the three-way tube 33 are each connected to one end of a branch tube 331. The inner wall of the three-way tube 33 is connected to the inner wall of the branch tube 331. Each branch tube 331 is connected to a tightening airbag 332 and their inner walls are connected. The inner wall of the tightening airbag 332 is in contact with the outer wall of the airway 24 and is annular.
[0051] The operation process involves the following steps: while training to press 21, the outer wall 211 monitors the pressing force and frequency in real time. Simultaneously, the inner wall 212 detects the concave and directional data generated on the side of the abdomen when pressing 21. 213 is used to detect interference caused by changes in the position of the entire module, such as tilting.
[0052] If the foam ball 241 is pushed out by air pressure and detaches from the inner wall of the airway 24, it is considered as a simulated blockage being discharged. At this time, the infrared sensor 23 does not detect an object above it, so the green light is lit, indicating that the blockage has been discharged. If the foam ball 241 is not discharged, it is considered as the blockage has not been discharged, so the red light is lit, and the buzzer 221 located on the main control PCB 22 will sound an alarm. The alarm will stop when the blockage is discharged.
[0053] In the above process: the abdominal pressure sensor 211 set on the side wall of the airbag 21 detects the pressure and frequency of the compression, the first angle sensor 212 detects the direction of the compression in real time, and the second angle sensor 213 detects the change in the position of the module in real time, so as to realize data integration and can intuitively reflect the emergency operation problems that occur during training.
[0054] Example 3, referring to Figures 3 to 10 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a training system that solves the shortcomings of existing electronic training systems, including a Heimlich maneuver training vest as described in the above embodiment.
[0055] Specifically, the back module 4 includes a control box 41 disposed on the side wall of the vest 1, and a back pressure sensor 42 is disposed on the side wall of the control box 41.
[0056] Furthermore, the other side of the control box 41 is fixedly connected to the back pressure sensor 42.
[0057] Specifically, the inner wall of the control box 41 is provided with a battery 43, the side wall of the battery 43 is provided with a female connector 431, and the side wall of the control box 41 is provided with a cover 44.
[0058] Furthermore, the lower inner wall of the control box 41 is fixedly connected to the battery 43, the side wall of the battery 43 is electrically connected to the female connector 431, the cover 44 is disposed between the vest 1 and the control box 41, and the cover 44 and the control box 41 are fixedly connected to each other, and the switch button 441 is used to control the power switch of the module and is electrically connected to the battery 43.
[0059] Specifically, a switch button 441 is provided on the side wall of the cover 44, a charging port 442 is provided below the switch button 441, and pearl cotton 45 is provided on the side wall of the control box 41.
[0060] Furthermore, the charging port 442 is electrically connected to the battery 43 for charging the battery 43. Pearl cotton 45 is disposed between the cover 44 and the vest 1, and the cover 44 and the vest 1 are connected.
[0061] Specifically, a workstation includes hardware, a monitor, a mouse, and a microphone.
[0062] Furthermore, the hardware system, including the controller and sensors, transmits the collected data to the display. The mouse can then be used to view the operational data generated by the Heimlich maneuver. For example, the back module 4 has a pressure sensor attached to its back, which can sense the force and frequency of back taps, the pressure and frequency of the abdominal module 2 pressure sensor, the direction of the pressure detected by the first angle sensor 212, and the interference caused by the change in the position of the entire module detected by the second angle sensor 213. The training personnel are then guided through the microphone, and the buzzer 221 emits a corresponding guidance sound.
[0063] In summary, this intelligent Heimlich training solution, achieved through the abdominal module, back module 4, and immersive component 3 combined with a workstation, provides realistic, real-time quantitative feedback and adaptability to diverse training scenarios. An ideal system should overcome the shortcomings of existing mannequins and fixed electronic teaching aids, transforming isolated, mechanical practice into immersive, interactive, and comprehensive training applicable to real-person collaboration.
