The intubation groove 1022 is used to guide the tracheal intubation. The telescopic positioning bolt 103 can be used to squeeze and fit the piston control rod 501 for positioning by rotating. The telescopic corrugated sheet 202 can utilize its corrugated structure to adapt to the change in the distance between the two sliding plates 201. The structure is simple and reasonable. The groove of the gum adaptation strip 302 is used to adapt to the gums of the patient. The inflatable cushion 301 can be inflated to ensure comfort in use.By adopting the provided gum protection part 3, the present structure is used to guide the opening plate 102 to move downward for opening work. In this process, wear and squeezing of the gums can be effectively prevented when the opening plate 102 moves downward. The protection of tracheal intubation for elderly patients or patients with loose teeth is more comprehensive, the patients are more comfortable after surgery, and the safety hazards are further reduced. The structure has strong adaptability. At the same time, the inflatable structure can better adapt to the gums. It is also softer and more comfortable after inflation, and will not cause local squeezing. The opening plate 102 of the present structure adopts the method of opening the intubation groove 1022 in the middle, which can directly inflate the air The cannula is inserted into the airway along the cannula groove 1022, which is more accurate. After the gum protection member 3 is placed in the oral cavity, the inflatable cushion 301 can be inflated to realize the opening work. The patient is more comfortable during the process. At the same time, when the opening plate 102 moves down and is inserted into the patient's oral cavity, the opening plate 102 and the sliding plate 201 slide and rub, and will not directly rub the patient's gums. At the same time, the inflatable cushion 301 also has a buffering effect after inflation. When the opening plate 102 moves down and slides, the telescopic corrugated sheet 202 can be adaptively telescoped, and the distance between the two sliding plates 201 increases as the opening plate 102 moves down, and the overall structure is more reasonable. ;

[0035] Among them, the pulling air guide 4 includes: a pulling wire 401 and an air pressure control tube 402, the end of the pulling wire 401 is fixedly installed on the top of the inner sliding plate 201; the pulling wire 401 is a soft steel wire; the air pressure control tube 402 is fixedly installed on the inner side of the inflatable cushion 301; the air pressure control tube 402 connects the two inflatable cushions 301; the pulling wire 401 is used to pull the opening plate 102 downward; the pulling wire 401 and the air pressure control tube 402 pass through the through slot provided on the connecting column 1021; the piston control component 5 includes: a piston control rod 501 and a piston 502, the end of the piston control rod 501 is provided with a handle; the piston control rod 501 is slidably plugged into the holding handle 101; the telescopic The end of the positioning bolt 103 is pressed against the piston control rod 501; the piston 502 is fixedly installed at the end of the piston control rod 501; the piston 502 slides and fits in the piston hole opened at the end of the gripping handle 101; the air pressure control tube 402 is fixedly installed at the outer end of the piston 502; the pulling wire 401 is fixedly installed at the outer end of the piston 502; the piston 502 is used to slide and pull the pulling wire 401; the piston control member 5 also includes: a piston exhaust hole 5021, the piston exhaust hole 5021 is opened on the piston 502; the piston exhaust hole 5021 is connected to the air pressure control tube 402; the piston exhaust hole 5021 introduces the air pressure generated by the sliding of the piston 502 into the air pressure control tube 402 and then fills it with air When the pad 301 and the piston 502 move outward, the air pressure inside the gripping handle 101 is squeezed to the air pressure control tube 402 and introduced into the inflatable pad 301. At this time, the inflatable pad 301 is gradually inflated as the sliding plate 201 moves downward to achieve inflatable protection. At this time, the telescopic positioning bolt 103 is tightened, and the end of the telescopic positioning bolt 103 can be used to fit the positioning piston control rod 501. When the opening plate 102 moves downward, the epiglottal protection airbag 601 is driven to move downward and stick to the epiglottis at the same time, which is convenient for subsequent related intubation work. The piston control part 5 can cooperate with the pulling air guide part 4 to pull the opening plate 102 into the oral cavity. The wire drawing 401 is pulled, and the focus is on the sliding plate 201 without squeezing the gums. There is no need to manually press down the opening plate 102, but it slides in by traction. During the process, the inflatable cushion 301 can also be inflated. As the opening plate 102 slides deeper, the inflation amount gradually increases. The whole process is simple to operate, which optimizes the disadvantages of the currently commonly used hand-held opening plate 102 that is directly inserted into the oral cavity. The doctor can operate flexibly and labor-saving, and the opening plate 102 will not cause friction with the sliding plate 201 when it moves down, causing the sliding plate 201 to generate downward pressure to damage the gums. The relative downward movement of the opening plate 102 is achieved by cleverly controlling the sliding plate 201 to slide upward by pulling.

[0036] Embodiment 2, as attached Figure 4 , Figure 8 , Fig. 9 and Fig.10As shown, on the basis of the first embodiment, the protective guide 6 includes: an epiglottal protective airbag 601, a silicone ring 602 and a liquid-absorbing pad 603, the epiglottal protective airbag 601 is fixedly mounted on the bottom of the opening plate 102; the epiglottal protective airbag 601 is a rubber soft structure; a silicone ring 602 is bonded to the side of the epiglottal protective airbag 601; the silicone ring 602 is used to prevent the intubation from damaging the glottis; the liquid-absorbing pad 603 is fixedly attached to the silicone ring 602; the liquid-absorbing pad 603 is used to absorb secretions at the glottis; the protective guide 6 also includes: a tracheal guide ring 604 and a tracheal fitting ring 6041, the tracheal guide ring 604 is fixedly mounted on the bottom of the silicone ring 602; the tracheal guide ring 604 is an inclined cylindrical structure; a tracheal fitting ring 6041 is fixedly bonded to the inner side of the tracheal guide ring 604; the tracheal fitting ring 6041 is used to fit the wall of the tracheal intubation tube, the protective guide 6 of this structure, By utilizing its soft structure, the accuracy of tracheal intubation is effectively improved without affecting the comfort of the patient. The funnel-shaped tracheal guide ring 604 is used to guide the tracheal tube into the airway when inserting the trachea. At the same time, the silicone ring 602 is located outside the tracheal guide ring 604, which can effectively reduce the risk of puncturing the glottis by the tube during tracheal intubation. This structure can also be attached to the tracheal tube through the tracheal fitting ring 6041 to prevent some saliva and other secretions from being discharged into the trachea during tracheal intubation. The absorbent pad 603 can absorb part of the secretions at the glottis of the oral cavity to avoid reflux of secretions and improve safety in use. The epiglottis protection airbag 601 adopts a soft airbag structure, which can move the epiglottis to prevent obstruction of the tracheal intubation. At the same time, the soft structure is more comfortable to use, avoiding excessive squeezing of the epiglottis caused by poor depth control during operation by the doctor.

[0037] The working principle of this embodiment is as follows: first, the patient opens his mouth under anesthesia, and places the patient's upper and lower gums in the grooves in the middle of the two gum adapter strips 302 respectively. The extrusion positioning of the piston control rod 501 is loosened by rotating the telescopic positioning bolt 103, and then the piston control rod 501 can be pulled out to drive the piston 502 to move outward. At this time, the piston 502 can pull the pulling wire 401 to drive the sliding plate 201 to slide on the opening plate 102. Because the sliding plate 201 is located between the upper and lower gums and does not move, under the interaction of forces, the position between the opening plate 102 and the oral cavity moves downward to achieve insertion into the oral cavity. The whole process will not wear the gums. When the piston 502 moves outward, the air pressure inside the gripping handle 101 is squeezed to the air pressure control tube 402 and introduced into the inflatable cushion 301. At this time, the inflatable cushion 301 slides with the sliding wire 401. As the movable plate 201 moves downward, the inflatable cushion 301 is also gradually inflated to achieve inflatable protection. At this time, the telescopic positioning bolt 103 is tightened to position the piston control rod 501. When the opening plate 102 moves downward, the epiglottis protection airbag 601 is driven to move downward at the same time and stick to the epiglottis. The epiglottis is squeezed and will be turned outward. At the same time, the tracheal guide ring 604 is located at the glottis for fitting. At this time, the tracheal tube passes through the intubation groove 1022 and is guided to the tracheal fitting ring 6041 by the funnel-shaped structure of the tracheal guide ring 604. The tracheal tube is sleeved through the tracheal fitting ring 6041 to achieve intubation. After the intubation is completed, the telescopic positioning bolt 103 is rotated to release the positioning of the piston control rod 501, and the telescopic positioning bolt 103 is retracted and reset. The structure can be removed from the patient's mouth. The overall structure is simple and reasonable, and it is easy to use.
