Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-7 , the present utility model provides a technical solution:

[0030] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown in

[0031] Refer to Figure 2 、 Figure 4 、 Figure 6 and Figure 7As shown in the figure, a clinical intubation anesthesia assistor, the bottom of the fixing plate 14 is fixedly and detachably connected with a fixing plate 37. A vertically penetrating channel 3 is opened at the center of the top of the fixing plate 37. The channel 3 is coaxially arranged with the channel 1. An auxiliary mouth-opening assembly is installed at the bottom of the fixing plate 37. The auxiliary mouth-opening assembly includes threaded rods 33 rotatably connected to the left and right sides of the bottom of the fixing plate 37. Rotating discs 30 are rotatably connected to the outer circles of the two threaded rods 33. The bottoms of the two threaded rods 33 are rotatably connected with horizontal rotating shafts 32. Three limiting telescopic rods 38 distributed in an annular array are fixedly connected to the top of the rotating disc 30. The tops of the three limiting telescopic rods 38 are fixedly connected to the bottom of the fixing plate 37. Fixed rings 35 are fixedly connected to the front and rear sides of the bottom of the rotating disc 30. Support plates 31 are rotatably connected to the left and right ends of the outer arc wall of the rotating shaft 32. A fixing ring 36 is fixedly connected to the center of the end of the side wall of the support plate 31 close to the threaded rod 33 and far from the rotating shaft 32. A fixing rod 34 is installed between the fixing ring 35 and the fixing ring 36. The three limiting telescopic rods 38 are used to prevent the auxiliary mouth-opening assembly from rotating. The two ends of the fixing rod 34 are respectively rotatably connected to the fixing ring 35 and the fixing ring 36. When the rotating disc 30 descends to the middle of the threaded rod 33, the included angle between the two support plates 31 on one rotating shaft 32 increases.

[0032] Refer to Figure 1 As shown in the figure, a clinical intubation anesthesia assistor, a cushion pillow 13 is provided on the top of the bed body 10. Chute 1s are opened on the left and right sides of the top of the front end of the bed body 10. Electric guides are arranged in the chute 1s. The cushion pillow 13 is located between the two chute 1s. Electric telescopic rods 12 are fixedly connected to the bottoms of the left and right ends of the fixing plate 14. Fixed ends of the two electric telescopic rods 12 are fixedly connected with sliders 11. The two sliders 11 are respectively slidably connected in the two chute 1s. The electric guide drives the slider 11 to move to drive the electric telescopic rod 12 and the fixing plate 14 to move. When the slider 11 moves to the front end of the chute 1, the patient will not hit the head when sitting up. When the slider 11 moves to the rear end of the chute 1, the auxiliary mouth-opening assembly is just located directly above the patient's mouth.

[0033] Refer to Figure 3 and Figure 5 As shown in the figure, a clinical intubation anesthesia assistor, when the five crescent-shaped limiting plates 22 are closed, the side walls close to the center are in contact with each other and form a hollow circle. When the five crescent-shaped limiting plates 22 are opened, they are all located inside the fixing plate 14. When the five crescent-shaped limiting plates 22 are opened, the inside of the channel 1 is unobstructed. When the five crescent-shaped limiting plates 22 are closed, the hollow circle formed by the side walls close to the center in contact with each other can fix the intubation. The diameter of the hollow circle is smaller than the cross-sectional diameter of the intubation.

[0034] Refer to Figure 4 、Figure 6 and Figure 7 As shown in Figure 7 , a clinical intubation anesthesia aid, on the top of the mutually approaching side walls of the support plates 31 on the same side of the two rotating shafts two 32, a pressing plate is installed, and a small lighting device is installed at the bottom of the pressing plate. The small lighting device is used to illuminate the patient's oral cavity and provide a field of view for intubation.

[0035] Refer to Figure 4 and Figure 6 As shown in Figure 6 , a clinical intubation anesthesia aid, the connection part of the threaded rod 33 and the rotating shaft two 32 is located between the connection parts of the two support plates 31 and the rotating shaft two 32. The threaded rod 33 is located within the circle formed by the three limit telescopic rods 38. None of the three limit telescopic rods 38 are located in the third channel. The connection part of the threaded rod 33 and the rotating shaft two 32 does not overlap or intersect with the connection part of the support plate 31 and the rotating shaft two 32.

[0036] Refer to Figure 4 、 Figure 6 and Figure 7 As shown in Figure 7 , a clinical intubation anesthesia aid, flexible materials are laid on the surfaces of the rotating shaft two 32, the support plate 31 and the pressing plate. The driving source for driving the threaded rod 33 is embedded in the fixing plate two 37. The flexible materials are used to prevent the parts of the auxiliary mouth-opening component from scratching the patient's oral cavity.

[0037] Refer to Figure 2 As shown in Figure 2 , a clinical intubation anesthesia aid, the diameters of the first channel and the third channel are equal. The distance between the two rotating shafts two 32 in the auxiliary mouth-opening component is less than the diameter length of the third channel. The first channel and the third channel reserve space for the doctor's intubation operation. The distance between the two rotating shafts two 32 can adapt to the oral cavity sizes of most patients.

[0038] Working principle:

[0039] Step 1: First, let the patient lie on the bed body 10 so that the patient's neck is located in the depression of the cushion pillow 13. After the patient is anesthetized, control the electric guide rail in the first chute to drive the slider 11 to move. The slider 11 then drives the electric telescopic rod 12 and the fixing plate one 14 to move directly above the patient's face, and align the first channel and the third channel with the patient's mouth. At this time, the annular limit component is in an open state.

[0040] Step 2: Control the electric telescopic rod 12 to slowly descend. At the same time, the doctor controls the patient's mouth to make the auxiliary mouth-opening assembly enter the patient's oral cavity. At this time, the doctor makes the patient's mouth slightly open so that the support plate 31 is located between the patient's upper and lower teeth. At this time, the pressing plate will press on the tongue and the small lighting device at the bottom of the pressing plate operates to illuminate the inside of the patient's oral cavity. Subsequently, the electric telescopic rod 12 immediately stops working. Then, the threaded rod 33 rotates to move the turntable 30 downward. The three limit telescopic rods 38 stretch synchronously with the turntable 30. When the turntable 30 moves downward, the fixed rod two 34 will push the support plate 31 accordingly, and two adjacent support plates 31 move away from each other to support the patient's gum to achieve the effect of opening the mouth.

[0041] Step 3: After the mouth is opened to an appropriate size, the threaded rod 33 stops rotating. At this time, the doctor can hold the laryngoscope and the intubation tube and enter the patient's oral cavity through passage one and passage three for tracheal intubation. After the intubation is completed, the laryngoscope is withdrawn. The doctor holds the intubation tube and immediately controls the annular limit assembly to work. The gear 20 drives the external gear ring 21 to rotate counterclockwise. The external gear ring 21 drives the five fixed rods one 23 to push the corresponding crescent-shaped limit plates 22 to gather inward to clamp and fix the intubation tube. After the intubation tube is fixed, control the threaded rod 33 to reverse to contract the auxiliary mouth-opening assembly to prevent the patient from opening the mouth too wide for a long time. After contraction, the distance between two adjacent support plates 31 can still prevent the patient from biting the intubation tube.

[0042] Step 4: After the operation is over, the doctor first holds the intubation tube and then controls the annular limit assembly to rotate the five crescent-shaped limit plates 22 clockwise to release the fixation of the intubation tube. Then, the intubation tube is taken out. Control the threaded rod 33 in the auxiliary mouth-opening assembly to reverse to make the support plates 31 approach each other to reduce the mouth-opening angle of the patient. Finally, control the electric telescopic rod 12 to slowly rise to make the auxiliary mouth-opening assembly leave the patient's oral cavity. Then, control the electric guide rail to drive the slider 11 to move to drive the fixed plate one 14 away from the patient's face. Subsequently, the auxiliary mouth-opening assembly can be removed for cleaning and disinfection.
