Among them, the splint assembly 1 can also use a lung bag, and the lung sac 2 is arranged in the lung bag to form a lung structure. The splint assembly 1 is provided with a tracheal connector 101, the first end of which is connected to the intrapulmonary space of the lung sac 2, and the second end of which is used to communicate with the trachea 7. In this way, the lung sac 2 can be inflated and exhausted through the trachea 7 and the tracheal connector 101, simulating the inhalation and exhalation movements, observing the changes in the volume of the lung sac 2 and the process of air entering and exiting the lung sac 2, which can help learners intuitively understand the respiratory mechanism and working principle of the lungs, and provide great help for training medical staff.

The splint assembly 1 is deformed by the adjustment component 3, and the size of the first accommodating space can be adjusted, so that the compliance of the lung sac 2 can be changed, so that the lung model forms a compliant splint lung, which is convenient for adjusting the intrapulmonary pressure of the lung sac 2, and can simulate the lungs of patients with different intrapulmonary pressures, thereby improving the scope of application of the lung model and meeting the use requirements, so that it can simulate the rescue of patients with different intrapulmonary pressures, and provide convenience for training medical staff.

[0024] In one embodiment, referring to Figure 1 The adjustment component 3 includes a first connecting seat 31, multiple second connecting seats 32 and a first elastic member 33; the first connecting seat 31 and the multiple second connecting seats 32 are all arranged on the clamping plate component 1; the first end of the first elastic member 33 is connected to the first connecting seat 31, and the second end of the first elastic member 33 is connected to any one of the multiple second connecting seats 32 to adjust the size of the first accommodating space of the clamping plate component 1.

[0025] As an example, the adjustment component 3 includes a first connecting seat 31, multiple second connecting seats 32 and a first elastic member 33; during installation, the first connecting seat 31 and the multiple second connecting seats 32 are all set on the clamping plate component 1, specifically, the first connecting seat 31 is set on the upper side wall of the first accommodating space, and the multiple second connecting seats 32 are spaced apart on the lower side wall of the first accommodating space; then the first end of the first elastic member 33 is connected to the first connecting seat 31, and the second end of the first elastic member 33 is connected to any one of the multiple second connecting seats 32; in this way, by adjusting the installation position of the second end of the first elastic member 33, the adjustment The compression amount of the first elastic member 33 is adjusted (for example, when the second end of the first elastic member 33 is connected to a second connection seat 32 closest to the first connection seat 31, the compression amount of the first elastic member 33 is the largest, and when the second end of the first elastic member 33 is connected to a second connection seat 32 farthest from the first connection seat 31, the compression amount of the first elastic member 33 is the smallest), so as to adjust the tension applied by the first elastic member 33 to the splint assembly 1, thereby adjusting the size of the first accommodating space of the splint assembly 1, so that the lung model has a plurality of different gears of intrapulmonary pressure, so as to simulate the lungs of patients with different intrapulmonary pressures, improve the scope of application of the lung model, and meet the use requirements. In this example, the compliance of the lung sac 2 can be changed by adjusting the hanging position of the second end of the first elastic member 33, so that the lung model forms a compliant splint lung, which is convenient for adjusting the intrapulmonary pressure of the lung sac 2, can simulate the lungs of patients with different intrapulmonary pressures, improve the scope of application of the lung model, meet the use requirements, and thus can simulate the rescue of patients with different intrapulmonary pressures, providing convenience for training medical staff.

[0026] In one embodiment, referring to Figure 1 The clamping plate assembly 1 includes a first clamping plate 102 and a second clamping plate 103 which are arranged opposite to each other; two ends of the first clamping plate 102 are connected to two ends of the second clamping plate 103, or the first clamping plate 102 and the second clamping plate 103 are integrally formed so that the first clamping plate 102 and the second clamping plate 103 cooperate to form a first accommodating space.

[0027] As an example, the splint assembly 1 includes a first splint 102 and a second splint 103, the first splint 102 and the second splint 103 are arranged opposite to each other, and the two ends of the first splint 102 are connected to the two ends of the second splint 103. Specifically, the first splint 102 and the second splint 103 can be connected by snap-fitting or suturing, etc., so that the first splint 102 and the second splint 103 cooperate to form a first accommodation space, so as to facilitate the disassembly, assembly and maintenance of the lung model. During installation, the first splint 102 and the second splint 103 are first assembled together to form a first accommodation space, and then the lung sac 2 is arranged in the first accommodation space. The splint assembly 1 and the lung sac 2 cooperate to form a lung structure. The size of the first accommodation space of the splint assembly 1 determines the size of the lung structure and limits the intrapulmonary pressure of the lung sac 2. It can simulate the patient's lungs and provide convenience for training medical staff.

[0028] In one example, the first splint 102 and the second splint 103 are integrally formed, that is, the splint assembly 1 is an integrally formed structure, which can reduce the assembly steps of the lung model and provide convenience for the user to install and disassemble the lung model. During design, a first accommodation space is provided in the integrally formed splint assembly 1, and the lung sac 2 is arranged in the first accommodation space. The splint assembly 1 and the lung sac 2 cooperate to form a lung structure. The size of the first accommodation space of the splint assembly 1 determines the size of the lung structure and limits the intrapulmonary pressure of the lung sac 2, which can simulate the patient's lungs and provide convenience for training medical staff.

[0029] In one embodiment, referring to Figure 1 , the first clamping plate 102 and the second clamping plate 103 are both arc-shaped plates.

[0030] As an example, the first splint 102 and the second splint 103 are both arc-shaped plates. With this arrangement, the overall structure of the splint assembly 1 is an elliptical structure, and the lung model formed by installing the lung sac 2 in the first accommodating space of the splint assembly 1 is closer to the real lung structure, providing convenience for training medical staff.

[0031] The embodiment of the present invention provides a model person, referring to Figure 1-4 , including a chest cover plate 4, a back cover plate 5, a head model 6, a trachea 7, a rib plate 8, a second elastic member 9, a press-reset assembly 10 and a lung model; the chest cover plate 4 is installed on the back cover plate 5, and a second accommodating space is formed between the chest cover plate 4 and the back cover plate 5; the head model 6 is installed at the neck of the chest cover plate 4 and the back cover plate 5; the rib plate 8 is attached to the inner wall of the chest cover plate 4, the first end of the second elastic member 9 is connected to the rib plate 8, and the second end of the second elastic member 9 is connected to the back cover plate 5; the press-reset assembly 10 and the lung model are both arranged in the second accommodating space, the first end of the press-reset assembly 10 is connected to the rib plate 8, and the second end of the press-reset assembly 10 is used to contact the lung model; the first end of the trachea 7 is connected to the lung model, and the second end of the trachea 7 is connected to the oral cavity 61 of the head model 6.

[0032] As an example, the model human includes a front chest cover plate 4, a back cover plate 5, a head model 6, a trachea 7, a rib plate 8, a second elastic member 9, a press-reset assembly 10 and a lung model; during installation, the front chest cover plate 4 is installed on the back cover plate 5, and a second accommodating space is enclosed between the front chest cover plate 4 and the back cover plate 5, and the second accommodating space is used to install a simulated human internal organ model; the rib plate 8 is attached to the inner wall of the front chest cover plate 4, the first end of the second elastic member 9 is connected to the rib plate 8, and the second end of the second elastic member 9 is connected to the back cover plate 5; with this arrangement, the elastic force of the second elastic member 9 can be used to support the rib plate 8. The pressing and resetting component 10 and the lung model are both arranged in the second accommodating space, the first end of the pressing and resetting component 10 is connected to the rib plate 8, and the second end of the pressing and resetting component 10 is used to contact the lung model. Specifically, the lung model is located below the rib plate 8, and the lung model is an inflated structural member; in this way, when the front chest cover plate 4 is pressed by external force, the rib plate 8 can compress the second elastic member 9, and the second elastic member 9 is compressed and deformed, which will reduce the distance between the front chest cover plate 4 and the back cover plate 5. At this time, the second accommodating space becomes smaller, and at the same time, the pressing and resetting component 10 is driven to press the lung model; when the external force is removed, the second elastic member 9 is reset, which will increase the distance between the front chest cover plate 4 and the back cover plate 5. At this time, the second accommodating space becomes larger, and at the same time, the pressing and resetting component 10 is driven away from the lung model; the above two processes are repeated continuously, and cardiopulmonary resuscitation is realized, which provides convenience for training medical staff. It can be understood that the second elastic member 9 includes but is not limited to a spring, etc. The front chest cover plate 4 can be installed on the back cover plate 5 by means of a buckle or other structure, which makes the disassembly between the front chest cover plate 4 and the back cover plate 5 simple, and provides convenience for the assembly and disassembly of the model person. Among them, a first plug-in portion 51 is provided on the inner wall of the back cover plate 5, and a second plug-in portion 81 is provided on the rib plate 8. The opposite ends of the second elastic member 9 are respectively plugged into the first plug-in portion 51 and the second plug-in portion 81, thereby ensuring the stability of the second elastic member 9 installed in the second accommodating space. There is also an elastic support strip 82 on the rib plate 8, and a plug-in hole is provided on the back cover plate 5. The elastic support strip 82 is plugged into the plug-in hole. The elastic support strip 82 can fit the rib plate 8 to the inner wall of the front chest cover plate 4, thereby improving the convenience of installing the rib plate 8.

[0033] The lung model in this example includes a splint assembly 1, a lung sac 2, and an adjustment assembly 3; when installed, a first accommodation space is provided in the splint assembly 1, and the lung sac 2 is arranged in the first accommodation space, and the splint assembly 1 and the lung sac 2 cooperate to form a lung structure; when the splint assembly 1 is deformed, the size of the first accommodation space of the splint assembly 1 determines the size of the lung structure, limits the intrapulmonary pressure of the lung sac 2, and can simulate the patient's lungs, providing convenience for training medical staff. Among them, the splint assembly 1 can also use a lung bag, and the lung sac 2 is arranged in the lung bag to form a lung structure. The splint assembly 1 is provided with a tracheal connector 101, the first end of which is connected to the intrapulmonary space of the lung sac 2, and the second end of which is used to communicate with the trachea 7. In this way, the lung sac 2 can be inflated and exhausted through the trachea 7 and the tracheal connector 101, simulating the inhalation and exhalation movements, observing the changes in the volume of the lung sac 2 and the process of air entering and exiting the lung sac 2, which can help learners intuitively understand the respiratory mechanism and working principle of the lungs, and provide great help for training medical staff. The adjustment component 3 is set on the splint assembly 1, and the splint assembly 1 can be deformed. The splint assembly 1 is deformed by the adjustment component 3, and the size of the first accommodating space can be adjusted, so that the compliance of the lung sac 2 can be changed, so that the lung model forms a compliant splint lung, which is convenient for adjusting the intrapulmonary pressure of the lung sac 2, and can simulate the lungs of patients with different intrapulmonary pressures, thereby improving the scope of application of the lung model and meeting the use requirements, so that it can simulate the rescue of patients with different intrapulmonary pressures, and provide convenience for training medical staff.

[0034] In this example, the head model 6 is installed on the neck of the front chest cover plate 4 and the back cover plate 5, so that a complete simulated human is formed, the first end of the trachea 7 is connected to the lung model, and the second end of the trachea 7 is connected to the oral cavity 61 of the head model 6; in this arrangement, when chest compression is not performed, the head model 6 of the model is tilted back to open the airway, and artificial respiration is performed through the oral cavity 61. When blowing, the air passes through the trachea 7 to reach the lung sac 2 of the lung model to cause the lung sac 2 to expand; when inhaling, the gas in the lungs will pass through the upper surface of the splint assembly 1 The first elastic member 33 compresses and discharges the lung sac 2, and discharges it from the body through the trachea 7. This is the first training process; when performing chest compression, the gas before compression reaches the lung sac 2 through the trachea 7, and the lungs are inflated; the chest cover plate 4 before pressing drives the pressing and resetting component 10 to move downward, so that the pressing and resetting component 10 squeezes the splint component 1 in the lung model (so that the operator has a pressing feel), the splint component 1 is deformed, the lung sac 2 is squeezed, and the gas in the lung sac 2 is discharged from the body through the trachea 7. This is the second training process. The model in this example can perform chest compression and tracheal 7 ventilation at the same time, which can provide two training modes for medical staff to train, increase the functionality of the equipment, and improve the scope of application of the equipment. Among them, the design of the trachea 7 can provide medical staff with tracheal intubation training. The trachea 7 is composed of multiple branches, which can be arranged according to patients of different heights to improve the applicability of the model.

[0035] In one embodiment, referring to Figure 3 and Figure 4 The pressing and resetting assembly 10 includes a resetting spring 1001 and a resetting plate 1002; the first end of the resetting spring 1001 is connected to the rib plate 8, the second end of the resetting spring 1001 is connected to the resetting plate 1002, and the resetting plate 1002 is used to abut against the lung model.

[0036] As an example, the pressing and resetting assembly 10 includes a resetting spring 1001 and a resetting plate 1002. When installing, the first end of the resetting spring 1001 is connected to the rib plate 8, and the second end of the resetting spring 1001 is connected to the resetting plate 1002. The resetting plate 1002 is used to abut against the lung model. In this way, after the gas reaches the lung sac 2 through the trachea 7 before pressing, the lung is inflated. The operator presses the front chest cover plate 4 by external force, so that the rib plate 8 drives the pressing and resetting spring 1001 and the resetting plate 1002 to move. The positioning plate 1002 moves to press the lung model, so that the reset plate 1002 squeezes the splint assembly 1 in the lung model, the splint assembly 1 is deformed, the lung sac 2 is squeezed, and the gas in the lung sac 2 is discharged from the body through the trachea 7. At the same time, the lung model will also feedback a force to the reset plate 1002, and the reset plate 1002 will feedback an elastic force to the operator of the chest compression through the reset spring 1001, simulating the squeezing feel of the lungs during chest compression, so as to provide compression training for medical staff. Among them, the number of reset springs 1001 is multiple, and the multiple reset springs 1001 are arranged at intervals to ensure the stability of the reset plate 1002.

[0037] In one embodiment, referring to Figure 3 and Figure 4 The model also includes an air resistance component 11, which is arranged on the trachea 7 and is used to adjust the passage size of the trachea 7.

[0038] As an example, the model man also includes an air resistance component 11. When installed, the air resistance component 11 is set on the trachea 7.

[0040] As an example, the mannequin also includes a sensor 12. When installed, the sensor 12 is set on the trachea 7 and connected to an external device. In this way, the external device generates gas and can inflate the lung model of the mannequin through the trachea 7; the sensor 12 can detect the gas flow in the trachea 7 and the pressure in the lung model and feed it back to the external device, so as to accurately control the amount of inflation to the lung model, thereby facilitating the adjustment of the intrapulmonary pressure of the lung sac 2, simulating the lungs of patients with different intrapulmonary pressures, improving the application range of the lung model, and meeting the use requirements. Among them, the sensor 12 is a flow and pressure sensor.

[0041] In one embodiment, referring to Figure 3 and Figure 4The model also includes an air port connector 13, which is arranged at the oral cavity 61 of the head model 6, is connected to the trachea 7, and is used to connect external equipment.

It can be understood that the second elastic member 9 includes but is not limited to a spring, etc. The front chest cover plate 4 can be installed on the back cover plate 5 by means of a buckle or other structure, which makes the disassembly between the front chest cover plate 4 and the back cover plate 5 simple, and provides convenience for the assembly and disassembly of the model person. Among them, a first plug-in portion 51 is provided on the inner wall of the back cover plate 5, and a second plug-in portion 81 is provided on the rib plate 8. The opposite ends of the second elastic member 9 are respectively plugged into the first plug-in portion 51 and the second plug-in portion 81, thereby ensuring the stability of the second elastic member 9 installed in the second accommodating space. There is also an elastic support strip 82 on the rib plate 8, and a plug-in hole is provided on the back cover plate 5. The elastic support strip 82 is plugged into the plug-in hole. The elastic support strip 82 can fit the rib plate 8 to the inner wall of the front chest cover plate 4, thereby improving the convenience of installing the rib plate 8.

[0045] The lung model in this example includes a splint assembly 1, a lung sac 2, and an adjustment assembly 3; when installed, a first accommodation space is provided in the splint assembly 1, and the lung sac 2 is arranged in the first accommodation space, and the splint assembly 1 and the lung sac 2 cooperate to form a lung structure; when the splint assembly 1 is deformed, the size of the first accommodation space of the splint assembly 1 determines the size of the lung structure, limits the intrapulmonary pressure of the lung sac 2, and can simulate the patient's lungs, providing convenience for training medical staff. Among them, the splint assembly 1 can also use a lung bag, and the lung sac 2 is arranged in the lung bag to form a lung structure. The splint assembly 1 is provided with a tracheal connector 101, the first end of which is connected to the intrapulmonary space of the lung sac 2, and the second end of which is used to communicate with the trachea 7. In this way, the lung sac 2 can be inflated and exhausted through the trachea 7 and the tracheal connector 101, simulating the inhalation and exhalation movements, observing the changes in the volume of the lung sac 2 and the process of air entering and exiting the lung sac 2, which can help learners intuitively understand the respiratory mechanism and working principle of the lungs, and provide great help for training medical staff. The adjustment component 3 is set on the splint assembly 1, and the splint assembly 1 can be deformed. The splint assembly 1 is deformed by the adjustment component 3, and the size of the first accommodating space can be adjusted, so that the compliance of the lung sac 2 can be changed, so that the lung model forms a compliant splint lung, which is convenient for adjusting the intrapulmonary pressure of the lung sac 2, and can simulate the lungs of patients with different intrapulmonary pressures, thereby improving the scope of application of the lung model and meeting the use requirements, so that it can simulate the rescue of patients with different intrapulmonary pressures, and provide convenience for training medical staff.

[0046] In this example, the head model 6 is installed on the neck of the front chest cover plate 4 and the back cover plate 5, so that a complete simulated person is formed. The first end of the trachea 7 is connected to the lung model, and the second end of the trachea 7 is connected to the oral area 61 of the head model 6; the ventilator 14 is an external device, and the ventilator 14 is linked with the model person. In this way, when chest compression is not performed, the model person wears a breathing mask or performs airway intubation, and the specific ventilator 14 is connected to the air port connector 13; when the ventilator 14 outputs gas, the gas passes through the air port connector 13 and the trachea 7 to reach the lung sac 2 to cause the lung sac 2 to expand; when the ventilator does not output gas, the gas in the lungs will be compressed and discharged from the lung sac 2 through the first elastic member 33 on the splint assembly 1, and discharged from the body through the trachea 7. When the gas flows through the sensor 12 on the trachea 7, the sensor 12 can To detect lung pressure and gas flow and feed back to the ventilator 14; when performing chest compression, when the ventilator 14 outputs gas, the gas passes through the gas port connector 13 and the trachea 7 to reach the lung sac 2 to cause the lung sac 2 to expand, press the front chest cover plate 4, so that the rib plate 8 drives the reset spring 1001 and the reset plate 1002 to move and press the lung model, so that the reset plate 1002 squeezes the splint assembly 1 in the lung model, the splint assembly 1 is deformed, the lung sac 2 is squeezed, and the gas in the lung sac 2 is discharged from the body through the trachea 7. At the same time, the lung model will also feed back a force to the reset plate 1002, and the reset plate 1002 feeds back an elastic force to the operator of chest compression through the reset spring 1001, simulating the squeezing feel of the lungs during chest compression, and the gas in the lung sac 2 is discharged from the body through the trachea 7. The model person in this example is linked to the ventilator 14. The gas flow in the trachea 7 and the pressure in the lung model are detected by the sensor 12 on the trachea 7 and fed back to the ventilator 14. The passage size of the trachea 7 is adjusted by the air resistance component 11 to simulate the degree of airway opening of people with different diseases. The pressure curve waveforms of different gears (ventilator 14 pipeline pressure) are fed back to the ventilator 14 to train medical staff on the regulation of the ventilator 14 according to different pressure curve waveforms. The model person can adjust the intrapulmonary pressure and feed it back to the ventilator 14 to simulate different diseased lung conditions, thereby improving the applicability of the model person and meeting usage requirements.
