Description

Technical Field

[0001] This invention relates to the field of medical and nursing rehabilitation equipment technology, specifically an oral intubation device. Background Technology

[0002] A significant proportion of critically ill patients remain unconscious for extended periods, relying on external aids for breathing and eating. This prolonged passive feeding without conscious awareness can easily lead to swallowing difficulties even after recovery. Furthermore, critically ill patients have a high rate of neurological damage, especially when there is excessive excitation of the sympathetic nervous system or damage between the nucleus ambiguus and the tuberous ganglion of the vagus nerve. This can cause cricopharyngeal muscle hysteresis, resulting in incomplete or uncoordinated relaxation of the muscle fibers. This can cause patients to feel a foreign object in their throat, often accompanied by choking, nasal and oral regurgitation, and other swallowing difficulties. In severe cases, there is even a high risk of food aspiration into the lungs.

[0003] Currently, both domestically and internationally, imported intubated balloon dilation or neuromuscular electrical stimulation (NMS) is commonly used for intervention. While NMS can directly stimulate the pharynx, its effectiveness alone is limited and requires active balloon relaxation to exercise the cricopharyngeal muscle. However, existing intubation balloon structures only provide simple relaxation stimulation and cannot induce swallowing movements similar to actual swallowing, thus limiting the effectiveness of swallowing training. To address these issues, a transoral intubation device is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an oral intubation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oral intubation device, comprising a bed, a support plate for supporting the patient's head at the front end of the bed, a first column fixedly connected to one side of the support plate, a support assembly at the upper end of the first column, a second column fixedly connected to one side of the bed, a control box fixedly connected to the upper end of the second column, a first trachea and a second trachea provided on the control box, the first trachea and the second trachea being fixedly engaged with the support assembly, the first trachea being slidably sleeved inside the second trachea, and the lower end of the first trachea penetrating the second trachea and inserted through the patient's mouth, the second trachea being provided with a swallowing exercise assembly for exercising the patient's swallowing function.

[0006] Preferably, the swallowing training component includes multiple first air sacs, a first airway, and valves. The multiple first air sacs are fitted side by side onto the outer wall of the second trachea. The second trachea has a first airway inside for injecting gas into the multiple first air sacs or extracting gas from the first air sacs, so that the multiple first air sacs are in a continuous cycle of contraction and expansion. The lower end of the first airway is connected to the lowermost first air sac. A valve is provided between two adjacent first air sacs to connect the two adjacent first air sacs. The multiple first air sacs are progressively larger from bottom to top.

[0007] Preferably, the swallowing training component includes a conical sleeve, an elastic membrane, a synovial cavity, a second airbag, a second airway, a third airway, and a fourth airway. An elastic membrane is fixedly connected to the outer wall of the conical sleeve. A synovial cavity is left between the elastic membrane and the conical sleeve. The second airbag is slidably connected inside the synovial cavity. A second airway is opened inside the second trachea. The lower end of the second airway is connected to the second airbag to realize the injection of gas into the second airbag or the extraction of gas from the second airbag. The third and fourth airways are opened inside the second trachea. The third and fourth airways are respectively connected to the upper and lower ends of the synovial cavity.

[0008] Preferably, a third airbag is provided on the outer wall of the second trachea and at both the upper and lower ends of the swallowing exercise component. A fifth airway is opened inside the second trachea to allow gas to be injected into the third airbag and then expanded. A drug supply channel and a sewage discharge channel are opened inside the second trachea. The drug supply port of the drug supply channel and the sewage discharge port of the sewage discharge channel are located between the two third airbags.

[0009] Preferably, the support assembly includes a support arm disposed at the upper end of the first column. A fixed clamp is fixedly connected to the end of the support arm away from the first column. A movable clamp is rotatably connected to the side wall of the fixed clamp. A clamping groove for clamping the second air tube is provided between the fixed clamp and the movable clamp. A pressure block is fixedly connected to the side wall of the movable clamp for fixing the second air tube inside the clamping groove. A fixed clamping plate is provided above the movable clamp. A movable clamping plate is slidably connected above the fixed clamping plate. A placement groove for fixing the first air tube is provided between the fixed clamping plate and the movable clamping plate.

[0010] Preferably, a plurality of reinforcing rings are evenly provided on the side wall of the second trachea and at the location of the swallowing exercise component to prevent the second trachea from being flattened.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The present invention enables the cricopharyngeal muscle of the patient to be supported and moved upward by the operation of the swallowing exercise component, so that the movement of the cricopharyngeal muscle during the exercise is close to the action of normal swallowing, thereby improving the exercise effect of the cricopharyngeal muscle.

[0013] 2. This invention injects gas into the interior of the third air sac through the fifth airway, causing the two third air sacs to inflate. In this way, during the exercise, the two third air sacs are fixed at both ends of the cricopharyngeal muscle, preventing the second trachea from moving around in the patient's throat, and further improving the exercise effect of the cricopharyngeal muscle.

[0014] 3. In this invention, after the two third air sacs are inflated by injecting gas into them through the fifth airway, the two third air sacs are placed close to the patient's throat. At this time, the two third air sacs and the cricopharyngeal muscle form a drug supply space. The drug is injected into the drug supply space through the drug supply channel, so that the drug will remain in the cricopharyngeal muscle. Furthermore, through the operation of the swallowing exercise component, the drug in the drug supply space is driven to peristalsis, which is more conducive to the absorption of the drug by the cricopharyngeal muscle.

[0015] 4. The present invention supports the first and second trachea through the support components, and the cooperation between the fixed clamp and the movable clamp, and the cooperation between the fixed clamp and the movable clamp, facilitates the replacement of the first and second trachea.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-19 The present invention provides a technical solution: a transoral intubation device, including a bed 1, wherein the front end of the bed 1 is provided with a support plate 101 for supporting the patient's head, such as... Figure 2 , 3 As shown, an electric push rod 102 is fixedly installed below the bed body 1. The output shaft of the electric push rod 102 is hinged to the lower side of the support plate 101. When the electric push rod 102 is activated, the output shaft of the electric push rod 102 will drive the support plate 101 to rotate upward, thereby adjusting the angle of the support plate 101 and thus effectively adjusting the height of the patient's head. A first column 2 is fixedly connected to one side of the support plate 101. A support component 3 is provided at the upper end of the first column 2. A second column 4 is fixedly connected to one side of the bed body 1. A control box 5 is fixedly connected to the upper end of the second column 4. A first trachea 6 and a second trachea 7 are provided on the control box 5. The first trachea 6 and the second trachea 7 are fixedly snapped onto the support component 3. The first trachea 6 is slidably sleeved inside the second trachea 7, and the lower end of the first trachea 6 passes through the second trachea 7 and is inserted into the patient's mouth. A swallowing exercise component 8 for exercising the patient's swallowing function is provided on the second trachea 7.

[0038] Example 1: Based on endotracheal intubation, in order to exercise the cricopharyngeal muscle of the patient and thus improve swallowing ability, the swallowing exercise component 8 specifically includes multiple first airbags 9, a first airway 10, and valves 11. The multiple first airbags 9 are arranged side-by-side on the outer wall of the second trachea 7. The second trachea 7 has a first airway 10 inside for injecting or extracting gas into the multiple first airbags 9, thus creating a continuous cycle of contraction and expansion of the multiple first airbags 9. The lower end of the first airway 10 communicates with the lowermost first airbag 9, and the upper end of the first airway 10 extends into the control box 5. A valve 11 is provided between adjacent first airbags 9 to connect them. The valve 11 is made of rubber. The cricopharyngeal muscle has a shape that is narrower at the bottom and wider at the top. Figure 10 As shown, after the multiple first air bladders 9 inflate, the multiple first air bladders 9 increase in size from bottom to top, which enables the multiple first air bladders 9 to better fit inside the cricopharyngeal muscle;

[0039] like Figure 10-13 As shown, when it is necessary to exercise the cricopharyngeal muscle of the patient, the second trachea 7 is slid down along the first trachea 6, causing the first air sac 9 to slide to the cricopharyngeal muscle. At this time, air is injected into the first airway 10 (through an external air pump or syringe, etc.). The air inside the first airway 10 first enters the lowermost first air sac 9, causing the lowermost first air sac 9 to inflate firstly. As air continues to be injected into the lowermost first air sac 9, when the lowermost first air sac 9 inflates to its maximum state, the valve 11 between the lowermost first air sac 9 and the previous first air sac 9 is opened by air pressure (the air pressure inside the lowermost first air sac 9), and the air passes through the valve 11. 1. Injection is injected from the bottommost first airbag 9 into the previous first airbag 9, thus opening the previous first airbag 9. This process is repeated, causing multiple first airbags 9 to inflate sequentially from bottom to top. When the topmost first airbag 9 inflates, these multiple first airbags will push the patient's cricopharyngeal muscle from bottom to top. Then, the air inside the multiple first airbags 9 is extracted through the first airway 10 (using an external air pump or syringe, etc.). After the air is extracted, the multiple first airbags 9 will contract, thus completing one swallowing exercise. By repeating the above operation, the multiple first airbags 9 are continuously contracted and inflated, thereby continuously exercising the cricopharyngeal muscle to mimic the patient's swallowing movements and improving the exercise effect of the cricopharyngeal muscle.

[0040] Example 2: Based on endotracheal intubation, in order to exercise the patient's cricopharyngeal muscles and thus improve swallowing ability, the swallowing exercise component 8 specifically includes a conical sleeve 13, an elastic membrane 14, a slurry cavity 15, a second air bladder 16, a second airway 17, a third airway 18, and a fourth airway 19. An elastic membrane 14 is fixedly connected to the outer wall of the conical sleeve 13. A slurry cavity 15 is provided between the elastic membrane 14 and the conical sleeve 13. The second air bladder 16 is slidably connected inside the slurry cavity 15, and the second air bladder 16 inflates. The connection between the second air tube 7 and the side wall of the sliding cavity 15 is a sliding seal. The second air tube 7 has a second air passage 17 inside. The lower end of the second air passage 17 is connected to the second airbag 16 to inject gas into the second airbag 16 or extract gas from the second airbag 16, so that the second airbag 16 inflates after gas is injected or contracts after gas is extracted. The second air tube 7 has a third air passage 18 and a fourth air passage 19 inside. The third air passage 18 and the fourth air passage 19 are connected to the upper and lower ends of the sliding cavity 15, respectively.

[0041] like Figure 15-17As shown, when it is necessary to exercise the cricopharyngeal muscle of the patient, the second trachea 7 is slid down along the first trachea 6, causing the swallowing exercise component 8 to slide to the cricopharyngeal muscle. At this time, air is injected into the second airway 17 (through an external air pump or syringe, etc.). The air is then injected into the second airbag 16 along the second airway 17. After the second airbag 16 is inflated, it will support the lower part of the elastic membrane 14. When the second airbag 16 is inflated, it will move the second airway 17 away from the first trachea 6. One end of the second airbag 16 is blocked (by sealing off the external air pump or syringe), thus fixing the second airbag 16 in the inflated state. In this state, gas is injected into the fourth airway 19 (via an external air pump or syringe, etc.). The gas flows along the fourth airway 19 and fills the interior of the sliding cavity 15 (below the second airbag 16) from the lower end of the sliding cavity 15. After the gas is injected into the interior of the sliding cavity 15, located below the second airbag 16, the second airbag 16 slides upwards, causing the position of the second airbag 16 supporting the elastic membrane 14 to gradually change upwards. The airbag 16 will then push the patient's cricopharyngeal muscle from bottom to top and inject air into the third airway 18 (at the same time, the air in the pleural cavity 15 below the second airbag 16 will be expelled through the fourth airway 19). At this time, the air will flow along the third airway 18 and fill the interior of the pleural cavity 15 from the upper end (above the second airbag 16). After the air is injected into the interior of the pleural cavity 15 and above the second airbag 16, the second airbag 16 will slide downward, causing the position of the second airbag 16 supporting the elastic membrane 14 to gradually move down and return to its original position. When the synovial cavity 15 reaches its lowest point, a swallowing exercise is completed. Following the above operation, the second air bladder 16 continuously slides up and down inside the synovial cavity 15, thereby continuously exercising the cricopharyngeal muscle to mimic the patient's swallowing movements and improving the efficiency of cricopharyngeal muscle exercise. In the above, the second airway 17, the third airway 18, and the fourth airway 19 are each connected to a separate external air pump (or syringe). By driving the piston rod of each external air pump (or syringe), the second airway 17, the third airway 18, and the fourth airway 19 are respectively injected or vented.

[0042] The conical sleeve 13 is fixedly fitted onto the outer wall of the second trachea 7. Under the outward supporting force of the conical sleeve 13, as the second air bladder 16 slides upward inside the sliding cavity 15, the greater the outward expansion of the elastic membrane 14 by the second air bladder 16, the more efficient the swallowing exercise becomes. Furthermore, a pressure regulator 26 (such as...) is connected in series with the second airway 17. Figure 19As shown, the pressure regulator 26 is an elastic bag with a volume much larger than the second airbag 16. While the second airbag 16 is being inflated, the pressure regulator 26 is also inflated and expanded. The air pressure inside the pressure regulator 26 is equal to the air pressure inside the second airbag 16. When the air pressure inside the second airbag 16 changes after the external pump is turned off, for example, when the air pressure inside the second airbag 16 decreases, a small amount of gas in the pressure regulator 26 will be added to the second airbag 16 to increase the air pressure inside the second airbag 16. Conversely, the gas inside the second airbag 16 flows into the pressure regulator 26 to decrease the air pressure inside the second airbag 16, thereby keeping the air pressure inside the second airbag 16 stable. In this way, when the second airbag 16 changes, the pressure regulator 26 plays a role in stabilizing the air pressure inside the second airbag 16, which can ensure that the air pressure inside the second airbag 16 remains constant, thereby reducing the impact on the expansion range of the elastic membrane 14 caused by the decrease in internal air pressure when the second airbag 16 slides inside the sliding cavity 15.

[0043] For both Embodiment 1 and Embodiment 2, the following functions can be added: such as Figure 13 , 14 As shown, when performing exercises to mimic the patient's swallowing movements, in order to prevent the second trachea 7 from shifting and to facilitate drug treatment of the cricopharyngeal muscle, thereby accelerating the patient's recovery, specifically, a third airbag 20 is provided on the outer wall of the second trachea 7 and at both the upper and lower ends of the swallowing exercise component 8. A fifth airway 21 is opened inside the second trachea 7 to allow gas to be injected into the third airbag 20 and then opened. A drug supply channel 22 and a sewage discharge channel 23 are opened inside the second trachea 7. The drug supply port of the drug supply channel 22 and the sewage discharge port of the sewage discharge channel 23 are located between the two third airbags 20.

[0044] External medication is needed to treat the patient's cricopharyngeal muscle (e.g., to reduce swelling). The control box 5 contains a medication bottle and a collection bottle. The medication bottle contains medication for treating the cricopharyngeal muscle, and the collection bottle collects waste fluid from the patient's cricopharyngeal muscle. The medication bottle is connected to the medication supply channel 22, and a driver (e.g., a peristaltic pump) is installed between the medication bottle and the medication supply channel 22 to drive the flow of the medication. The collection bottle is connected to the drainage channel 23, and a driver (e.g., a peristaltic pump) is installed between the collection bottle and the drainage channel 23 to drive the flow of waste fluid. When medication is needed, the fluid is transferred to the... Gas is injected into the fifth airway 21, causing the fifth airway 21 to introduce gas into the interior of the two third air sacs 20. At this time, the two third air sacs 20 inflate after being injected with gas, so that the two third air sacs 20 are in close contact with the patient's throat (located at both ends of the cricopharyngeal muscle). The drug supply space formed by the two third air sacs 20 and the cricopharyngeal muscle is then injected into the drug supply space through the drug supply channel 22 by the peristaltic pump. In this way, the drug will remain in the cricopharyngeal muscle. During the drug supply process, the gas in the drug supply space is discharged through the drainage channel 23, thereby avoiding the increase of air pressure inside the drug supply space and damage to the cricopharyngeal muscle.

[0045] Example 3 (the above scheme with the addition of a third airbag 20 based on Example 1): After the drug is injected into the drug supply space, the first airway 10 is repeatedly injected and de-inflated, causing multiple first airbags 9 to inflate and then contract sequentially from bottom to top. In this way, the multiple first airbags 9 will drive the drug in the drug supply space to peristalsis, which is conducive to the absorption of the drug by the cricopharyngeal muscle.

[0046] Example 3 (the above scheme with the addition of a third airbag 20 based on Example 1): After the medicine is injected into the supply space, when the first airbag 9 is inflated, not all of the first airbags 9 will inflate. For example, if there are 5 first airbags 9, when the medicine in the supply space is driven to move, 3 of the first airbags 9 will inflate. In this way, it can be ensured that the first airbags 9 can drive the medicine to move in the supply space, and it can also be ensured that there is some space left in the supply space to hold the medicine, so as to avoid the first airbags 9 from completely filling the supply space. The number of first airbags 9 that are inflated is controlled by the air intake. By injecting different amounts of gas, the number of first airbags 9 that inflate can be controlled.

[0047] Example 4 (the above scheme with the addition of a third airbag 20 based on Example 2): After the drug solution is injected into the drug supply space, gas is injected into the interior of the second airway 17, causing the second airbag 16 to inflate after the gas is injected. At this time, the second airbag 16 is supported by the elastic membrane 14. Then, gas is injected into the interior of the sliding cavity 15 in a cyclical alternation using the third airway 18 and the fourth airway 19, causing the second airbag 16 to slide up and down continuously inside the sliding cavity 15, thereby driving the drug solution in the drug supply space to peristalsis, which is conducive to the absorption of the drug solution by the cricopharyngeal muscle.

[0048] Example 4 (the above scheme with the addition of a third airbag 20 based on Example 2): The outer surface of the elastic membrane 14 is uniformly provided with grooves. When driving the liquid medicine to peristalsis, the elastic membrane 14 will come into contact with the cricopharyngeal muscle. At this time, the liquid medicine can flow from the contact position between the elastic membrane 14 and the cricopharyngeal muscle through the grooves. For example, after the second airbag 16 slides upward, the contact position between the elastic membrane 14 and the cricopharyngeal muscle changes upward continuously. At this time, the liquid medicine will be pushed upward by the elastic membrane 14. At this time, the liquid medicine above the contact position between the elastic membrane 14 and the cricopharyngeal muscle will flow downward along the grooves, avoiding the liquid medicine being squeezed out after the space above the contact position between the elastic membrane 14 and the cricopharyngeal muscle gradually becomes smaller. Conversely, when the second airbag 16 slides downward, the liquid medicine below the contact position between the elastic membrane 14 and the cricopharyngeal muscle will flow upward along the grooves. When the second airbag 16 slides downward, the supply space below the contact position between the elastic membrane 14 and the cricopharyngeal muscle decreases, and the liquid medicine is forced to flow upward by compression.

[0049] For the above embodiments: liquid may accumulate in the drug supply space. The drain duct 23 can be used to absorb the liquid inside the drug supply space and guide it into the liquid bottle. If the patient has phlegm in his / her throat, the drain duct 23 can also be used to absorb it, which is beneficial for cleaning up waste liquid in the patient's throat.

[0050] Specifically: When exercising the cricopharyngeal muscle to mimic the patient's swallowing movements, the two third air sacs 20 are in an inflated state. In this way, during the exercise, the two third air sacs 20 are fixed at both ends of the cricopharyngeal muscle (the fixed position can be far away from the cricopharyngeal muscle), preventing the second trachea 7 from moving around in the patient's throat and reducing the efficiency of exercising the cricopharyngeal muscle.

[0051] like Figure 2 , 6 As shown in Figure 9, in order to fix the first trachea 6 and the second trachea 7, specifically, the support assembly 3 includes a support arm 301, which is disposed at the upper end of the first column 2, as shown in Figure 9. Figure 2 As shown, the support arm 301 includes multiple support rods, and the connection points of adjacent support rods can be rotated and adjusted, thereby effectively adjusting the end position of the support arm 301. This allows the ends of the first trachea 6 and the second trachea 7 to be moved directly above the patient's mouth. A fixed clamp 302 is fixedly connected to the end of the support arm 301 away from the first column 2. A movable clamp 303 is rotatably connected to the side wall of the fixed clamp 302. A clamping groove for clamping the second trachea 7 is provided between the fixed clamp 302 and the movable clamp 303. A pressure block 304 is fixedly connected to the side wall of the movable clamp 303 to fix the second trachea 7 inside the clamping groove. Figure 6 , 7As shown, one side of the movable clamp 303 is rotatably connected to the side wall of the fixed clamp 302, and a snap-fit ​​block 307 is fixedly connected to the side wall of the fixed clamp 302. The snap-fit ​​block 307 is movably snapped onto the side wall of the movable clamp 303 to achieve the purpose of closing and fixing the movable clamp 303. By bending the snap-fit ​​block 307, the movable clamp 303 can be opened to facilitate the removal of the second air tube 7 from the inside of the clamping groove. When the movable clamp 303 is closed, the pressure block 304 will press against the side wall of the second air tube 7, thereby fixing the second air tube 7 inside the clamping groove. The pressure block 304 is provided with a handle, which can be pressed... After pressing the handle, the lower end of the pressure block 304 will rotate outward, thereby eliminating the pressing force of the pressure block 304 on the second air tube 7. At this time, the second air tube 7 can slide inside the clamping groove. When the handle is released, the pressure block 304 elastically returns to its original position, and then the pressure block 304 will press against the side wall of the second air tube 7 again. At this time, the second air tube 7 will be fixed inside the clamping groove again. A fixed clamping plate 305 is provided above the movable clamping seat 302. A movable clamping plate 306 is slidably connected above the fixed clamping plate 305. A placement groove for fixing the first air tube 6 is provided between the fixed clamping plate 305 and the movable clamping plate 306. Figure 8 , 9 As shown, the upper side of the fixed clamping plate 305 has a insertion groove 308, and the lower side of the movable clamping plate 306 is fixedly connected to an insertion block 309. The insertion block 309 is movably inserted into the insertion groove 308, thereby fixing the movable clamping plate 306 inside the fixed clamping plate 305. Figure 9 As shown, after placing the first air tube 6 on the fixed clamp 305, align the left end of the insertion block 309 with the right end of the insertion slot 308, and push the movable clamp 306 to the left. At this time, the insertion block 309 slides into one end of the insertion slot 308. When the insertion block 309 is fully slid into the insertion slot 308, the movable clamp 306 is fastened above the fixed clamp 305, thus fixing the first air tube 6. Conversely, after pushing the movable clamp 306 to the right, the insertion block 309 slides out from the insertion slot 308, and the movable clamp 306 can be completely removed from the fixed clamp 305. At this time, the first air tube 6 can be removed from the fixed clamp 306.

[0052] like Figure 10 , 16As shown, during swallowing exercises, to prevent the second trachea 7 from being flattened and affecting the ventilation of the first trachea 6, specifically, multiple reinforcing rings 25 are evenly provided on the side wall of the second trachea 7 and at the location of the swallowing exercise component 8 to prevent the second trachea 7 from being flattened. When the patient's swallowing function is exercised through the swallowing exercise component 8, the swallowing exercise component 8 exerts a supporting force on the cricopharyngeal muscle, causing the cricopharyngeal muscle to exert a counter-compressive force on the swallowing exercise component 8. This compressive force acts on the second trachea 7, and through the supporting effect of the reinforcing rings 25, the second trachea 7 can be prevented from being flattened, ultimately preventing the risk of hypoxia in the patient after the first trachea 6 is flattened.

[0053] like Figure 5 , 18 As shown, when a patient is in a prolonged unconscious state, their mouth opening and closing function will decline. In order to exercise the patient's mouth opening and closing function, a mouth opening and closing exercise component 12 for exercising the patient's mouth opening and closing function is provided on the second trachea 8 and on the side wall of the swallowing exercise component 8. The mouth opening and closing exercise component 12 includes a connecting block 1201. Two opening and closing plates 1202 are symmetrically and rotatably connected to both sides of the connecting block 1201. Each opening and closing plate 1202 is provided with a telescopic air bag 1203 between it and the connecting block 1201 to expand the opening and closing plate 1202 outward. The second trachea 7 has a sixth airway 24 for injecting gas into the telescopic air bag 1203. The outer side wall of the opening and closing plate 1201 has a tooth groove 1204 for the patient to bite.

[0054] The method for exercising the patient's mouth opening and closing function is as follows: Slide the second trachea 7 downwards, causing the two opening and closing plates 1202 to be positioned between the upper and lower teeth, prompting the patient's upper and lower teeth to bite into the alveolar bone 1204. At this time, air is injected or de-inflated into the telescopic air bag 1203 through the sixth airway 24. When air is injected into the telescopic air bag 1203, the telescopic air bag 1203 inflates, pushing against the opening and closing plates 1202 and thus causing the patient's mouth to open. When the air is de-inflated into the telescopic air bag 1203, the telescopic air bag 1203 deflates, and no longer supports the opening and closing plates 1202. Through the patient's own mouth muscles resetting, the mouth muscles will drive the opening and closing plates 1202 to return to their original position, at which point the patient's mouth closes. Continuously cycling the action of injecting or de-inflating the telescopic air bag 1203 can exercise the patient's mouth opening and closing function.

[0055] In the above process, the control box 5 is equipped with multiple air pumps, which supply air to the first airbag 9, the second airbag 16, the third airbag 20, the sliding cavity 15, and the telescopic air bag 1203 respectively. The control box 5 is also equipped with a controller. Medical staff can control the multiple air pumps to supply air to the first airbag 9, the second airbag 16, the third airbag 20, the sliding cavity 15, and the telescopic air bag 1203 respectively through the controller. The controller can also control the peristaltic pump to operate. Since the air pump, peristaltic pump, and controller are not within the scope of this application, and there are many existing technologies, they will not be described in detail. For example, the controller model can be AT89S52.
