Description

Technical Field

[0001] The utility model relates to the technical field of teaching aids, in particular to a Heimlich training teaching aid. Background Technique

[0002] Acute respiratory foreign body obstruction will cause the patient to be unable to breathe, and may cause death due to hypoxia. The Heimlich abdominal thrust method is to hug the patient and suddenly press on the upper abdomen. Since the thoracic cavity is airtight and there is only one opening in the trachea, the gas in the thoracic cavity (trachea and lungs) will naturally rush towards the trachea under the action of pressure. Each impact will generate 450-500 milliliters of gas, so it is possible to expel the foreign body and restore the patency of the airway, thus saving the patient.

[0003] When medical staff teach the Heimlich abdominal thrust method, it is very difficult to intuitively demonstrate its principle and process by artificial demonstration, and some existing teaching aids cannot allow medical staff to be fully trained. For this reason, we propose a Heimlich training teaching aid. Content of the Utility Model

[0004] In view of this, the utility model provides a Heimlich training teaching aid, which is used to solve the problem that the learning of the Heimlich abdominal thrust method in the prior art cannot be fully and realistically trained.

[0005] A Heimlich training teaching aid includes a human-shaped transparent airbag model and a support base; wherein, the transparent airbag model is fixedly connected to a connecting seat; a human organ simulation structure is arranged inside the transparent airbag model; the top of the support base is connected with a support tube with an external thread, and a sleeve is threadedly connected to the support tube. The upper end of the sleeve fixedly penetrates through the connecting seat and is hermetically communicated with the inside of the transparent airbag model; an inflation mechanism for inflating the transparent airbag model is installed inside the support base.

[0006] Preferably, the above-mentioned human organ simulation structure includes a mouth part, the mouth part is opened on the surface of the transparent airbag model, one side of the mouth part is communicated with a slideway, the lower end of the slideway is connected with a trachea, and the connection part between the slideway and the trachea is set as an epiglottis simulation part. The upper part of the connecting seat is connected with a thoracic cage simulation cover through a connecting frame, the lower part of the thoracic cage simulation cover is connected with an abdominal cavity simulation bag, a closed cavity is formed between the thoracic cage simulation cover and the abdominal cavity simulation bag, and a rubber membrane is connected to the bottom of the thoracic cage simulation cover; a lung simulation shell is connected inside the thoracic cage simulation cover through a support frame, and the lower end of the trachea is hermetically penetrated through the top of the thoracic cage simulation cover and communicated with the inside of the lung simulation shell; a soft filling block is arranged inside the abdominal cavity simulation bag.

[0007] Preferably, a proximity sensor is installed through one side of the epiglottis simulation part in a sealed manner. The proximity sensor is connected to the DSP controller on the support base through a connecting wire. A timer and an audible and visual alarm are installed on the support base, and both the audible and visual alarm and the timer are controlled by the DSP controller.

[0008] Preferably, the inflation mechanism includes an air pump. A through hole communicating with the inside of the support tube is formed on the support base.

[0028] To enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] Embodiment 1

[0030] Please refer to Figures 1-4 , a Heimlich training teaching aid, including a human-shaped transparent airbag model 300 and a support base 100. The transparent airbag model 300 is fixedly connected to a connecting seat 202; a human organ simulation structure is arranged inside the transparent airbag model 300; wherein, a support tube 200 with an external thread is connected to the top of the support base 100, a sleeve 201 is threadedly connected to the support tube 200, the upper end of the sleeve 201 fixedly penetrates through the connecting seat 202 and is hermetically communicated with the inside of the transparent airbag model 300; an inflation mechanism for inflating the transparent airbag model 300 is installed inside the support base 100.

[0031] Specifically, during implementation, as Figure 2 shown, the human organ simulation structure includes a mouth part 301, the mouth part 301 is opened on the surface of the transparent airbag model 300, a slideway 400 is communicated with one side of the mouth part 301, the lower end of the slideway 400 is connected to a trachea 600, the connection part between the slideway 400 and the trachea 600 is set as an epiglottis simulation part 401, the upper part of the connecting seat 202 is connected to a chest simulation cover 700 through a connecting frame 703, the lower part of the chest simulation cover 700 is connected to an abdominal cavity simulation bag 702, a sealed cavity is formed between the chest simulation cover 700 and the abdominal cavity simulation bag 702, and a rubber film 602 is connected to the bottom of the chest simulation cover 700, wherein the rubber film 602 is equivalent to the diaphragm of the human body; a lung simulation shell 601 is connected inside the chest simulation cover 700 through a support frame 603, wherein the lung simulation shell 601 is made of rubber material or soft PVC material, the lower end of the trachea 600 is hermetically penetrated through the top of the chest simulation cover 700 and is communicated with the inside of the lung simulation shell 601; a soft filling block 701 is arranged inside the abdominal cavity simulation bag 702, wherein the soft filling block 701 is made of soft materials such as sponge and cotton block. Specifically, during implementation, the slideway 400, the trachea 600, the epiglottis simulation part 401 and the chest simulation cover 700 are all made of transparent soft PVC structures.

[0032] During implementation, the inflation mechanism includes an air pump. A through hole 101 communicating with the inside of the support tube 200 is provided on the support base 100. The air outlet of the air pump is communicated with the through hole 101, and a solenoid valve is also installed between the air outlet of the air pump and the through hole 101. The solenoid valve is controlled by the DSP controller 106. A ventilation port 107 communicating with the air inlet of the air pump is provided on one side of the support base 100. A storage battery is installed inside the support base 100, and a charging socket 105 for charging the storage battery is provided on the side wall of the support base 100. When in use, open the solenoid valve, start the air pump, and inflate the inside of the transparent airbag model 300 through the air pump. When the inflation is almost done, manually intervene to stop the air pump and close the solenoid valve. When deflating, just open the solenoid valve to exhaust air.

[0033] As Figure 1 shown in the figure, the bottom of the support base 100 is set to be arc-shaped. The arc-shaped structure facilitates the artificial swinging of the transparent airbag model 300 during operation, which is convenient for training.

[0034] First of all, it should be noted that under normal circumstances, the epiglottis is closed when swallowing food;

[0035] If choking, breathing incoordination, disease or other conditions occur, it may cause the epiglottis to open, and the opening of the epiglottis easily causes food or foreign objects to fall into the airway.

[0036] Specifically in use, the Heimlich training teaching aid realizes at least two teaching functions:

[0037] First, it demonstrates the reason for foreign objects falling into the trachea. As Figure 2 shown in the figure, since the transparent airbag model 300 is transparent, the epiglottis simulation part 401 inside can be directly observed from the outside. When the epiglottis is in an open state, after the foreign object simulation ball 500 enters from the mouth part 301, it is very easy to block the air inlet of the trachea 600 after passing through the slideway 400, thus forming a respiratory obstruction. This function realizes the process of simulating that when a person swallows food, the epiglottis does not close, resulting in foreign objects easily falling into the trachea, so as to understand the reason for foreign objects falling into the trachea.

[0038] Second, it more intuitively demonstrates the principle of the Heimlich method and conducts training. As Figure 2As shown in the figure, by squeezing the abdomen, the pressure inside the abdominal cavity simulation bag 702 (simulating the human abdominal cavity) increases, thereby pressing the rubber membrane 602 (simulating the human diaphragm), causing the pressure inside the thoracic cavity simulation cover 700 (simulating the human thoracic cavity) to increase, and further pressing the lung simulation shell 601 (simulating the human lungs) and the trachea 600 (simulating the human trachea), generating an impact airflow inside the trachea 600, and thus ejecting the foreign object simulation ball 500 at the opening of the trachea 600 from the mouth 301; this function simulates and demonstrates the process of a person, when a foreign object blocks the trachea, increasing the pressure in the abdominal cavity, thoracic cavity, and lungs by performing abdominal compression, so as to eject the foreign object; it can not only visually display the principle of the Heimlich method, but also realize the training of the Heimlich abdominal thrust method.

[0039] Embodiment 2

[0040] Different from Embodiment 1, as Figure 2 shown in the figure, a proximity sensor 501 is hermetically installed through one side of the epiglottis simulation part 401. The proximity sensor 501 is connected to the DSP controller 106 on the support base 100 through the connecting wire 102. A timer 104 and a sound and light alarm 103 are installed on the support base 100. Both the sound and light alarm 103 and the timer 104 are controlled by the DSP controller 106.

[0041] Specifically during implementation, the connecting wire 102 passes through the sleeve 201 and the support tube 200, and the lower end of the connecting wire 102 is hermetically installed through the side wall of the through port 101. The connecting wire 102 has a redundant length, and even if it rotates a small number of turns (the rotation between the support tube 200 and the sleeve 201), it does not affect normal use.

[0042] During use, after the foreign object simulation ball 500 is thrown into the mouth 301, the foreign object simulation ball 500 falls from the slideway 400 into the epiglottis simulation part 401, and then can be sensed by the proximity sensor 501, so that the DSP controller 106 controls the sound and light alarm 103 to give an alarm and the timer 104 to start timing; it can create a tense atmosphere according to the sound and light alarm 103, and can also judge the proficiency of the training through the timing of the timer 104, which is very convenient.

[0043] Obviously, the embodiments described above are only a part of the embodiments of this application, rather than all of them. The preferred embodiments of this application are shown in the drawings, but they do not limit the patent scope of this application. This application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of this application more thorough and comprehensive. Although this application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any equivalent structures made by using the content of this application's specification and drawings, directly or indirectly applied in other related technical fields, are equally within the scope of the patent protection of this application.
