[0016] The present invention provides a respiratory system care training model through improvement, which has the following improvements and advantages compared with the prior art:

[0017] First, the present invention can make the lung sac continuously contract and expand through the breathing simulation device, so that air can be continuously exhaled and inhaled, thereby more completely simulating the breathing action of the human lungs and providing a better nursing training simulation effect. Moreover, the adjustment mechanism therein can adjust the movement stroke of the pressure plate. The greater the reciprocating movement stroke of the pressure plate, the more air can be pressed into or drawn out of the space below the diaphragm on the inner side of the chest cavity, thereby adjusting the degree of contraction and expansion of the lung sac, and then adjusting the total amount of air inhaled and exhaled by the lung sac, thereby simulating the effects of deep breathing and shallow breathing of the human lungs.

[0018] Second, the present invention forms an irregular cross-section on the inner side of the flexible trachea through the cooperation of the breathing simulation device and the asthma simulation device, thereby simulating the uneven state of the respiratory tract cross-section caused by respiratory tract swelling in asthma patients. Therefore, when air flows through the flexible trachea, the air inside it will produce a wheezing sound, thereby simulating the respiratory system state of asthma patients.

[0019] Third: The present invention cooperates with the breathing simulation device and the coughing simulation device. When the diaphragm applies a large pressure to the lung sacs, the sliding block is controlled to move back and forth, so that the straight channel is alternately connected to the second breathing tube and the second terminal trachea. When the straight channel is connected to the second breathing tube and the second terminal trachea, the high-pressure air inside the two lung sacs can be quickly ejected outward through the trachea, the second breathing tube, the straight channel, and the second terminal trachea. When the straight channel is isolated from the second breathing tube, the high-pressure air in the two lung sacs stops ejecting outward, thereby simulating the state of the human respiratory system when coughing.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides a respiratory system care training model through improvement. The technical solution of the present invention is:

One end of the rotating shaft 106 and the rotating shaft 2 107 are both fixed with a rotating rod 108. A connecting shaft 109 is movably connected between the two rotating rods 108 through an adjusting mechanism.

A first motor 114 is installed on the inner side of the shell 116, and a worm 115 meshing with the worm gear 113 is fixed to the driving end of the first motor 114.

[0035] Furthermore, the adjustment mechanism includes two slide grooves 110 provided inside the two rotating rods 108, screw rods 112 are rotatably inserted inside the two slide grooves 110, and sliders 111 are slidably connected inside the two slide grooves 110, the two screw rods 112 are respectively threadedly connected to the two sliders 111, and one side of the two sliders 111 is respectively fixedly connected to the two ends of the connecting shaft 109;

[0036] The movement stroke of the pressing plate 104 can be adjusted through the adjustment mechanism. The larger the reciprocating movement stroke of the pressing plate 104 is, the more air can be pressed into or extracted from the space below the diaphragm 3 inside the chest cavity 1, thereby adjusting the degree of contraction and expansion of the lung sac 2, and then adjusting the total amount of air inhaled and exhaled by the lung sac 2, thereby simulating the effects of deep breathing and shallow breathing in the human lungs.

[0037] Furthermore, the asthma simulation device includes a first housing 201 connected to the end of the breathing tube 6, and a flexible airway 202 (such as a flexible airway 202 connected to the breathing tube 6) is provided inside the first housing 201. Figure 6As shown), a first terminal air pipe 206 communicating with the flexible air pipe 202 is fixed at the upper end of the first shell 201, two rotating wheel shafts 203 are rotatably connected to the inner side of the first shell 201 at the two sides of the flexible air pipe 202, a plurality of rotating wheels 204 are fixed at equal intervals on the outer sides of the two rotating wheel shafts 203, and a plurality of irregularly arranged bosses 205 are arranged on the outer side of each rotating wheel 204, a second motor 207 is installed at one end of the outer side of the first shell 201, a driving end of the second motor 207 is fixedly connected to one end of one of the rotating wheel shafts 203, a pulley 208 is fixed to one end of the two rotating wheel shafts 203, and the two pulleys 208 are connected by a belt 209;

[0038] By using the asthma simulation device, the inner side of the flexible trachea 202 is formed into an irregular cross-section, thereby simulating the uneven cross-section of the respiratory tract caused by the swelling of the respiratory tract of an asthma patient. Therefore, when the air flows through the flexible trachea 202, the air inside the flexible trachea 202 will produce a wheezing sound, thereby simulating the respiratory system state of an asthma patient.

[0039] Further, the cough simulation device includes a second housing 301 (such as Figure 7 As shown in the figure, a sliding block 303 is slidably connected to one end of the inner side of the second shell 301, and a second terminal air pipe 302 aligned with the breathing tube 27 is connected to one side of the second shell 301, a direct current channel 304 is provided inside the sliding block 303, and a third motor 305 is installed at the other end of the inner side of the second shell 301, a rotating column 308 is fixed to the driving end of the third motor 305, and a guide groove is provided on the outer side of the rotating column 308, an extension plate 306 is fixed to one end of the sliding block 303, and a sliding pin 307 slidably adapted to the guide groove is fixed to one end of the extension plate 306, and the guide groove includes a first spiral groove 309 and a second spiral groove 310 respectively provided on both sides of the rotating column 308 (as shown in the figure). Fig. 9 As shown), both ends of the first spiral groove 309 and the second spiral groove 310 are smoothly connected to each other;

[0040] Through the cough simulation device, the sliding block 303 therein is moved back and forth, so that the direct channel 304 is alternately connected with the breathing tube 27 and the second terminal trachea 302. When the direct channel 304 is connected with the breathing tube 27 and the second terminal trachea 302, the high-pressure air inside the two lung sacs 2 can be quickly ejected outward through the trachea 4, the breathing tube 27, the direct channel 304, and the second terminal trachea 302. When the direct channel 304 is isolated from the breathing tube 27, the high-pressure air in the two lung sacs 2 stops ejecting outward, thereby simulating the state of the human respiratory system when coughing.

[0041] Further, the reversing mechanism includes a cylindrical housing 401 (such as Figure 1 As shown in FIG. 1 ), the inner side of the cylindrical housing 401 is rotatably connected to a reversing column 402 (as shown in FIG. Figure 4 As shown in FIG. 4 ), a right-angle flow channel 403 is provided inside the reversing column 402, an extension shaft 404 extending to the outside of the cylindrical housing 401 is fixed to one end of the reversing column 402, and levers 405 are fixed to both sides of the extension shaft 404;

[0042] The trachea 4 can be connected to the breathing tube 1 6 and the breathing tube 2 7 respectively through the reversing mechanism. When the trachea 4 is connected to the breathing tube 1 6, the second motor 207 of the asthma simulation device stops and the first motor 114 of the driving mechanism runs, which can simulate the effects of continuous breathing, deep breathing and shallow breathing of the lung sac 2. When the second motor 207 of the asthma simulation device and the first motor 114 of the driving mechanism run at the same time, the state of the respiratory system during asthma can also be simulated. When the trachea 4 is connected to the breathing tube 2 7, the pressure plate 104 of the breathing simulation device is controlled to move up to the highest point and then stop, so that the space inside the chest cavity 1 below the diaphragm 3 maintains a higher air pressure, and then the third motor 305 of the cough simulation device is controlled to run to intermittently release the high-pressure air at the lower end of the inner side of the chest cavity 1, which can simulate the coughing effect of the respiratory system.

[0043] Working principle: During the training simulation, the first motor 114 of the control driving mechanism drives the worm 115 to rotate, the worm 115 drives the worm wheel 113 to rotate, the worm wheel 113 drives the second shaft 107 of the breathing simulation device to rotate, the second shaft 107 drives the rotating rod 108 at its end to rotate, this rotating rod 108 drives another rotating rod 108 to rotate synchronously through the connecting shaft 109, and the other rotating rod 108 drives the rotating shaft 106 to rotate. When the two rotating rods 108 rotate, the connecting shaft 109 is driven by the two sliders 111 to make a circular motion around the rotating shaft 106 and the second shaft 107, and the connecting shaft 109 drives the sliding rod 105 through the connecting rod 105. 03 moves up and down, and the slide bar 103 drives the pressure plate 104 to move up and down. When the pressure plate 104 moves down, the air in the space below the diaphragm 3 on the inner side of the chest cavity 1 is sucked into the inner side of the air cylinder 101, thereby reducing the space below the diaphragm 3 on the inner side of the chest cavity 1 and increasing the space above the diaphragm 3 on the inner side of the chest cavity 1. Therefore, the volume of the two lung sacs 2 increases, and the external air is sucked in. When the pressure plate 104 moves up, the air inside the air cylinder 101 is pressed into the space below the diaphragm 3 on the inner side of the chest cavity 1, thereby increasing the space below the diaphragm 3 on the inner side of the chest cavity 1, thereby compressing the two lung sacs 2 and discharging the air inside the two lung sacs 2 to the outside through the trachea 4.

[0044] The lever 405 of the reversing mechanism drives the extension shaft 404 to rotate, the extension shaft 404 drives the reversing column 402 to rotate, and the reversing column 402 drives the right-angle flow channel 403 inside it to rotate. When the right-angle flow channel 403 connects the trachea 4 and the breathing tube 6, the two lung sacs 2 can be directly connected to the outside world through the trachea 4 and the breathing tube 6. At this time, under the action of the breathing simulation device, the two lung sacs 2 can be contracted and expanded, thereby more completely simulating the breathing action of the human lungs and providing a better nursing training simulation effect;

[0045] The two screw rods 112 of the adjustment mechanism are rotated. When the two screw rods 112 rotate, the two sliders 111 are driven to slide along the inner side of the slide groove 110 through the threads respectively. The two screw rods 112 are kept rotating synchronously, so that the two sliders 111 can move synchronously, and the two sliders 111 drive the connecting shaft 109 to move, and the connecting shaft 109 drives one end of the connecting rod 105 to move, so that the distance between the connecting shaft 109 and the rotating shaft 106 and the rotating shaft 2 107 can be adjusted, and then the distance between the end of the connecting rod 105 connected to the connecting shaft 109 and the rotating shaft 106 and the rotating shaft 2 107 can be adjusted. When the distance between the connecting shaft 109 and the rotating shaft 106 and the rotating shaft 2 107 is larger, the stroke of each reciprocating movement of the pressing plate 104 is larger, so each time more air can be pressed into or extracted from the space below the diaphragm 3 inside the chest cavity 1, so that the contraction and expansion degree of the lung sac 2 can be adjusted, and then the total amount of air inhaled and exhaled by the lung sac 2 can be adjusted, so that the effect of deep breathing and shallow breathing of the human lungs can be simulated;

[0046] While the breathing simulation device is running, the second motor 207 of the asthma simulation device is controlled to drive one of the rotating wheel shafts 203 to rotate, and then the two rotating wheel shafts 203 can be synchronously rotated through the transmission connection between the two pulleys 208 and the belt 209, and the two rotating wheel shafts 203 respectively drive the multiple rotating wheels 204 on the outside to rotate. Since a plurality of irregularly arranged bosses 205 are arranged on the outside of each rotating wheel 204, when the multiple rotating wheels 204 located on both sides of the flexible trachea 202 rotate, the plurality of bosses 205 on the outside of each rotating wheel 204 can squeeze the side wall of the flexible trachea 202, so that the inner side of the flexible trachea 202 forms an irregular cross section, thereby simulating the uneven state of the respiratory tract cross section caused by the swelling of the respiratory tract of the asthma patient. Therefore, when the air flows through the inner side of the flexible trachea 202 with an irregular cross section, a wheezing sound is generated, thereby simulating the respiratory system state of the asthma patient;

[0047] When the trachea 4 and the breathing tube 2 7 are connected by the reversing mechanism, the breathing tube 1 6 and the trachea 4 are disconnected. When the pressing plate 104 moves up to the highest point, the first motor 114 of the driving mechanism is controlled to stop running. Under the self-locking effect between the worm 115 and the worm wheel 113, the pressing plate 104 can be kept at the highest point. Figure 2As shown in the figure, at this time, the space below the diaphragm 3 on the inner side of the chest cavity 1 maintains a relatively high air pressure, and at the same time, the two lung sacs 2 are subjected to the pressure of the diaphragm 3. Since the direct current channel 304 is not connected to the breathing tube 2 7 at this time, the air inside the two lung sacs 2 cannot be discharged to the outside when the two lung sacs 2 are subjected to pressure. When the third motor 305 controlling the cough simulation device is running, it drives the rotating column 308 to rotate, and the rotating column 308 drives the first spiral groove 309 and the second spiral groove 310 on both sides to rotate, and the sliding pin 307 slides along the inner side of the first spiral groove 309 and the second spiral groove 310. When the sliding pin 307 slides inside the first spiral groove 309 and the second spiral groove 310, it is subjected to opposite forces, so when the sliding pin 307 slides inside the first spiral groove 309 and the second spiral groove 310, it can give The extension plate 306 applies an opposite thrust, so under the guiding action of the first spiral groove 309 and the second spiral groove 310, the extension plate 306 and the sliding block 303 can be driven to move back and forth through the sliding pin 307, and the sliding block 303 drives the direct current channel 304 to move back and forth, so that the direct current channel 304 can be alternately connected with the breathing tube 27 and the second terminal trachea 302. When the direct current channel 304 is connected with the breathing tube 27 and the second terminal trachea 302, the high-pressure air inside the two lung sacs 2 can be quickly ejected outward through the trachea 4, the breathing tube 27, the direct current channel 304, and the second terminal trachea 302. When the direct current channel 304 is isolated from the breathing tube 27, the high-pressure air in the two lung sacs 2 stops ejecting outward, thereby simulating the state of the human respiratory system when coughing.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
