Description

Technical Field

[0001] The utility model relates to the technical field of teaching aids, in particular to an auxiliary teaching aid for breathing function training. Background Art

[0002] Breathing refers to the process of gas exchange between the body and the external environment. The human breathing process includes three interrelated links: external respiration, gas transport in the blood, and internal respiration. In the medical field, the respiratory department will study the movement of the lungs when the human body breathes, so a breathing simulation device will be used for observation. In the teaching process, teaching aids or models are usually used to demonstrate and explain abstract theoretical knowledge or mechanisms of occurrence, to concretize and visualize knowledge, to combine students' concrete perception and abstract thinking, and to reduce the difficulty of mastering and understanding abstract concepts.

[0003] Current breathing simulation teaching aids can generally only simulate for students the movement of a person's lungs during normal breathing. They cannot simulate the movement of a person's lungs when breathing after a foreign object is stuck in the throat, or the movement of a person's lungs when taking deep breaths to exhale more carbon dioxide. Therefore, the simulation function of the equipment is limited. Utility Model Content

[0004] The utility model aims to solve the problem that the existing auxiliary teaching aids for respiratory function training cannot simulate the lung movement state when a foreign object is stuck in the throat of a person or when a person takes deep breath.

[0005] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0006] A respiratory function training auxiliary teaching aid, comprising a bracket and a display frame arranged between inner walls on both sides of the bracket, and also comprising:

[0007] A simulation component, the simulation component comprising an air tube arranged at the top of the display frame, a first air bag and a second air bag arranged at one end of the air tube located inside the display frame, and a balloon sleeved at the bottom of the display frame;

[0008] An extrusion assembly, the extrusion assembly comprising a screw threadedly disposed on a side wall of one end of the bracket, a fixing rod fixedly disposed on the side wall of the other end of the bracket, a pressing block disposed at an end of the screw away from the bracket, and a stopper disposed at an end of the fixing rod away from the bracket;

[0009] An air intake assembly is arranged on the top of the support and is used to inflate and deflate the first air bag and the second air bag to simulate the lung breathing state.

[0010] As a preferred technical solution of the present application, the air intake assembly includes an air box arranged on the top of the bracket, a pressure plug slidably arranged on the inner wall of the air box, a cylinder arranged on the top of the air box, and a piston rod arranged at the output end of the cylinder, the bottom of the piston rod is connected to the top of the pressure plug, and the air pipe is connected to the air box.

[0011] As a preferred technical solution of the present application, an air pump is also provided on the top of the bracket, a connecting pipe is provided between the output end of the air pump and the air pipe, and a valve is provided on the outside of the air pipe.

[0012] As a preferred technical solution of the present application, a U-shaped bifurcated tube is provided at one end of the air tube located inside the display frame, one air outlet end of the bifurcated tube is connected to the first airbag, and the other air outlet end of the bifurcated tube is connected to the second airbag.

[0013] As a preferred technical solution of the present application, a fixing sleeve is provided on the side wall of the display frame near the bottom, a sealing strip is provided on the inner wall of the fixing sleeve, a sealing groove matching the sealing strip is provided on the side wall of the display frame near the bottom, a positioning block is provided on the side wall of the fixing sleeve, and a screw is threadedly connected on the surface of the positioning block.

[0014] As a preferred technical solution of the present application, the side walls at both ends of the display frame are provided with mounting plates, the outer wall of the bracket is threadedly connected with bolts, the side walls of the mounting plate are provided with screw holes matching with the bolts, the bottom of the air pipe is provided with a threaded sleeve, and the threaded sleeve is threadedly connected to the top of the display frame.

[0015] As a preferred technical solution of the present application, the display frame is made of transparent plastic material.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The air intake assembly is provided to continuously inflate and then deflate the first airbag and the second airbag, so that the first airbag and the second airbag continuously expand and then contract. When the first airbag and the second airbag expand, the balloon will be squeezed to bulge downward, and when the first airbag and the second airbag contract, the balloon will rebound upward and reset. Therefore, the first airbag can be regarded as the left lung of a person, the second airbag can be regarded as the right lung, and the balloon can be regarded as the diaphragm membrane. Therefore, when the first airbag and the second airbag are inflated and deflated, the movement state of the first airbag, the second airbag and the balloon will be the same as the movement state of the lungs and the diaphragm membrane when a person breathes, thereby simulating the state of the lungs when a person breathes to the trainees and improving the students' understanding ability.

[0018] 2. Through the set extrusion component, when the first airbag and the second airbag are inflated and deflated to simulate the breathing state of a person's lungs, the screw can also be rotated to drive the pressing block to move the trachea on one side of the extrusion. At this time, the other side of the trachea will be blocked by the block, and the trachea can be squeezed. The squeezing force can be adjusted as needed. At this time, the gas passing through the trachea will become less. At this time, the movement state of the first airbag, the second airbag and the balloon is observed, so as to simulate the lung breathing condition when a foreign object is stuck in the throat of a person, which is convenient for teaching students.

[0019] 3. Because the amount of gas filled into the first airbag and the second airbag by the air intake component always remains unchanged, it can only simulate the inhalation state of a person during normal and steady breathing. The teaching staff can close the air intake component, then start the air pump, and fill a large amount of gas into the trachea through the connecting tube to expand the first airbag and the second airbag to the maximum extent possible, and then open the valve to release the gas in the first airbag and the second airbag, thereby simulating the lung movement state when a person takes deep breath, inhales a large amount of gas at one time and then exhales it all to completely expel carbon dioxide, which further facilitates teaching to students.

[0027] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] like Figures 1 to 4 As shown, the present embodiment proposes a respiratory function training auxiliary teaching aid, comprising a bracket 1 and a display frame 2 arranged between the inner walls on both sides of the bracket 1, and also comprising a simulation component, an extrusion component and an air intake component, the simulation component comprising a trachea 3 arranged at the top of the display frame 2, a first air bag 301 and a second air bag 302 arranged at one end of the trachea 3 located inside the display frame 2, and a balloon 4 sleeved on the bottom of the display frame 2, the extrusion component comprising a screw rod 5 threadedly arranged on the side wall of one end of the bracket 1, a fixing rod 6 fixedly arranged on the side wall of the other end of the bracket 1, a pressing block 501 arranged at the end of the screw rod 5 away from the bracket 1, and a stopper 601 arranged at the end of the fixing rod 6 away from the bracket 1, and the air intake component is arranged at the top of the bracket 1, and is used to inflate and deflate the first air bag 301 and the second air bag 302 to simulate the lung breathing state;

[0029] The air intake assembly can be used to inflate and then deflate the first airbag 301 and the second airbag 302. This operation can be repeated to continuously inflate and deflate the first airbag 301 and the second airbag 302. When the first airbag 301 and the second airbag 302 are inflated, they will expand, and when the gas in the first airbag 301 and the second airbag 302 is extracted, they will shrink. When the first airbag 301 and the second airbag 302 expand, they will squeeze the balloon 4 to bulge downward, and when the first airbag 301 and the second airbag 302 shrink, the balloon 4 will rebound upward and reset. Therefore, the first airbag 301 in this application can be regarded as the left lung of a person, the second airbag 302 can be regarded as the right lung, and the balloon 4 can be regarded as the diaphragm membrane. Therefore, when the first airbag 301 and the second airbag 302 are operated, the first airbag 301 and the second airbag 302 are operated. When the airbag 302 is inflated and deflated, the movement states of the first airbag 301, the second airbag 302 and the balloon 4 will be the same as the movement states of the lungs and diaphragm membrane when a person breathes, thereby simulating the lung state of a person when breathing to the trainees and improving the students' understanding ability; at the same time, the screw 5 can also be rotated to drive the pressure block 501 to move and squeeze one side of the trachea 3. At this time, the other side of the trachea 3 will be blocked by the block 601, so that the trachea 3 can be squeezed, and the squeezing force can be adjusted as needed. At this time, the gas passing through the trachea 3 will become less. At this time, by watching the movement states of the first airbag 301, the second airbag 302 and the balloon 4, it is possible to simulate the lung breathing situation when a person has a foreign object stuck in his throat and cannot breathe normally, which is convenient for teaching the trainees.

[0030] The display frame 2 is made of transparent plastic material; the display frame 2 made of transparent material allows people to clearly see the movement states of the first airbag 301, the second airbag 302 and the balloon 4 simulating the lungs and the diaphragm membrane.

[0031] In addition, a U-shaped bifurcated tube 13 is provided at one end of the air tube 3 located inside the display frame 2, and an air outlet end on one side of the bifurcated tube 13 is connected to the first air bag 301, and an air outlet end on the other side of the bifurcated tube 13 is connected to the second air bag 302; the bifurcated tube 13 is provided to facilitate the gas passing through the air tube 3 to be stably and evenly filled into the first air bag 301 and the second air bag 302.

[0032] like Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the air intake assembly includes an air box 7 arranged on the top of the bracket 1, a pressure plug 9 slidably arranged on the inner wall of the air box 7, a cylinder 8 arranged on the top of the air box 7, and a piston rod 801 arranged at the output end of the cylinder 8, the bottom of the piston rod 801 is connected to the top of the pressure plug 9, and the air pipe 3 is connected to the air box 7;

[0033] The starting cylinder 8 drives the plunger 9 to move up and down reciprocatingly through the piston rod 801. When the plunger 9 moves downward, it squeezes the gas in the air box 7 into the first air bag 301 and the second air bag 302 through the trachea 3. When the plunger 9 moves upward, the gas in the first air bag 301 and the second air bag 302 is drawn back into the air box 7. The cycle can make the first air bag 301 and the second air bag 302 continuously expand and then contract, so as to simulate the state of the left lung and the right lung of a person when breathing.

[0034] like Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, an air pump 10 is provided on the top of the bracket 1, a connecting pipe 1001 is provided between the output end of the air pump 10 and the air pipe 3, and a valve 303 is provided outside the air pipe 3;

[0035] When it is necessary to simulate the movement state of the lungs when a person takes a deep breath, the cylinder 8 can be closed, the air pump 10 can be started, and a large amount of gas can be filled into the trachea 3 through the connecting tube 1001, so that the first air bag 301 and the second air bag 302 can be expanded to the maximum state as much as possible and the balloon 4 can be squeezed to bulge downward, and then the air pump 10 is closed, and the valve 303 is opened to allow the gas in the first air bag 301 and the second air bag 302 to be discharged and contracted, thereby simulating the movement state of the lungs and diaphragm membrane when a person takes a deep breath, inhales a large amount of air, and then exhales to completely expel carbon dioxide, further facilitating teaching to students. It should be noted that a gas detector is provided on the outside of the air pump 10, which can detect the gas capacity filled by the air pump 10. Therefore, according to the maximum amount of air inhaled by a normal person, an appropriate amount of gas can be filled into the first air bag 301 and the second air bag 302, thereby improving the accuracy of the simulation state.

[0036] like Figure 2 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a fixing sleeve 11 is provided on the side wall of the display frame 2 near the bottom, a sealing strip 1101 is provided on the inner wall of the fixing sleeve 11, a sealing groove 201 matching with the sealing strip 1101 is provided on the side wall of the display frame 2 near the bottom, a positioning block 1102 is provided on the side wall of the fixing sleeve 11, and a screw is threadedly connected on the surface of the positioning block 1102;

[0037] After the balloon 4 is put on the bottom of the display frame 2, the fixing sleeve 11 is put on the outside of the display frame 2 to press the balloon 4 around. At this time, the sealing strip 1101 on the inner wall of the fixing sleeve 11 will be pressed into the sealing groove 201, thereby improving the stability and sealing of the fixation of the balloon 4. Then the screw is passed through the positioning block 1102 and screwed into the side wall of the display frame 2, so that the balloon 4 can be easily fixed and disassembled.

[0038] like Figures 3 to 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, both end side walls of the display frame 2 are provided with mounting plates 12, the outer wall of the bracket 1 is threadedly connected with bolts 101, the side wall of the mounting plate 12 is provided with screw holes matching with the bolts 101, the bottom of the air pipe 3 is provided with a threaded sleeve 202, and the threaded sleeve 202 is threadedly connected with the top of the display frame 2;

[0039] The bolt 101 is passed through the bracket 1 and screwed into the screw hole on the mounting plate 12, so that the display frame 2 can be installed on the inner side of the bracket 1. When the display frame 2 needs to be disassembled for maintenance or replacement, the bolt 101 is screwed out of the mounting plate 12 to loosen the display frame 2, and then the threaded sleeve 202 at the bottom of the air pipe 3 is screwed out of the display frame 2, so as to facilitate the installation, disassembly and maintenance of the display frame 2.

[0040] The working principle of the utility model is as follows: the air intake assembly is provided to continuously inflate and then deflate the first airbag 301 and the second airbag 302. When the first airbag 301 and the second airbag 302 expand, the balloon 4 will be squeezed to bulge downward, and when the first airbag 301 and the second airbag 302 contract, the balloon 4 will rebound upward and reset. Therefore, the first airbag 301 in the present application can be regarded as the left lung of a person, the second airbag 302 can be regarded as the right lung, and the balloon 4 can be regarded as the diaphragm membrane. Therefore, when the first airbag 301 and the second airbag 302 are inflated and deflated, the movement state of the first airbag 301, the second airbag 302 and the balloon 4 will be the same as the movement state of the lungs and the diaphragm membrane when a person breathes, so as to simulate the lung state of a person when breathing to the trainees and improve the students' understanding ability. At the same time, the screw 5 can also be rotated to drive the pressing block 50 1 moves and squeezes the trachea 3. At this time, the gas passing through the trachea 3 will become less. At this time, the movement states of the first airbag 301, the second airbag 302 and the balloon 4 are observed, so as to simulate the lung breathing when a person's throat is stuck with a foreign object and cannot breathe normally, which is convenient for teaching students; and when it is necessary to simulate the lung movement state when a person breathes deeply, close the cylinder 8 and start the air pump 10, and fill a large amount of gas into the trachea 3 through the connecting pipe 1001, so as to expand the first airbag 301 and the second airbag 302 to the maximum state as much as possible and squeeze the balloon 4 to bulge downward, and then open the valve 303 to let the gas in the first airbag 301 and the second airbag 302 be discharged and contracted, so as to simulate the movement state of the lungs and diaphragm membrane when a person breathes deeply once, inhales a large amount of air and then exhales to completely expel carbon dioxide, which is further convenient for teaching students.
