[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-7 , the present invention provides a fixing device for facilitating oral intubation of children, including an arc-shaped plate 1. A through hole 2 is provided on the surface of the arc-shaped plate 1. A fixed tube 3 is fixedly provided on the inner wall of the through hole 2. Two stop blocks 4 are fixedly provided on the surface of the arc-shaped plate 1. A limit assembly 5 is provided at the top of each of the two stop blocks 4. A storage groove 6 is provided on one side of each of the two stop blocks 4. A vertical rod 7 is rotatably connected to the inner wall of each of the two storage grooves 6 through a bearing. A winding roller 8 is fixedly provided on the surface of each of the two vertical rods 7. A bandage 9 is wound around the surface of each of the two winding rollers 8. A hook surface of a magic tape 10 is fixedly provided on the inner surface of one of the bandages 9, and a loop surface of a magic tape 11 is fixedly provided on the outer surface of the other bandage 9. Hold the ends of the two bandages 9 and pull the bandages 9 to make the two bandages 9 wind around the child's head. The fixing device is fixed on the child's face through the adhesion of the loop surface of the magic tape 11 and the hook surface of the magic tape 10. The length of the bandage 9 is adjusted by winding the bandage 9 on the winding roller 8, so as to facilitate the use of children with different head circumferences.

[0028] One end of the fixed tube 3 is provided with a bite tube 12. The surface of the bite tube 12 is fixedly provided with a moving seat 25 through a plastic screw 24. The top and bottom ends of the moving seat 25 are both fixedly provided with dental pads 26. Slide the bite tube 12 into the oral cavity. At this time, the upper and lower teeth respectively fit against the two dental pads 26. The dental pads 26 are elastic and protect the upper and lower teeth. Remove the plastic screw 24, and then remove the moving seat 25 and the dental pads 26. Children under 1 year old do not need the dental pads 26, while children over 1 year old need the dental pads 26. Therefore, through the cooperation of the plastic screw 24, the moving seat 25 and the dental pads 26, the dental pads 26 can be disassembled and installed according to needs, which is suitable for children of different ages. One end of each of the two vertical rods 7 penetrates through the inner wall of the top end of the corresponding storage groove 6 and is fixedly provided with a rotation assisting cap 13. The surfaces of the rod bodies of the two vertical rods 7 extending to the outside are both fixedly provided with positioning blocks 14. For those skilled in the art, rotate the rotation assisting cap 13, and the rotation assisting cap 13 drives the vertical rod 7 to rotate, and the bandage 9 will be wound around the winding roller 8.

[0029] Furthermore, in order to prevent the vertical rod 7 from rotating, the vertical rod 7 is fixed by a limiting component 5. Specifically, the limiting component 5 includes an L-shaped groove 501 opened at the top end of the block 4. One inner wall of the L-shaped groove 501 is provided with a return spring 502. One end of the return spring 502 is fixedly provided with a sliding plate 503 that slides in the L-shaped groove 501. The top end of the sliding plate 503 is fixedly provided with a limiting plate 504. The top end of the limiting plate 504 is fixedly provided with a boosting frame 509. Push the limiting plate 504 through the boosting frame 509, so that the limiting plate 504 moves away from the vertical rod 7. The limiting plate 504 compresses the return spring 502 through the sliding plate 503. The return spring 502 can elongate and push the sliding plate 503 and the limiting plate 504 to move in the reverse direction after the boosting frame 509 is released.

[0030] A sliding groove 505 is opened on the surface of the limiting plate 504. A limiting groove 506 that engages with the positioning block 14 is opened on the inner wall of the sliding groove 505. The inner wall of the sliding groove 505 is slidably connected to the surface of the vertical rod 7. The bottom end of the limiting plate 504 is slidably connected to the top end of the block 4. The positioning block 14 will be caught inside the limiting groove 506 when the limiting plate 504 moves in the reverse direction. At this time, the limiting plate 504 resists the positioning block 14 through the limiting groove 506, thereby fixing the vertical rod 7 and the winding roller 8.

[0031] A sliding rod 507 is fixedly provided on the inner wall of the L-shaped groove 501. A sliding hole 508 is opened on the surface of the sliding plate 503. The inner wall of the sliding hole 508 is slidably connected to the surface of the sliding rod 507. The return spring 502 is sleeved outside the sliding rod 507. The top end of the boosting frame 509 is provided with anti-slip lines. The sliding rod 507 guides the movement of the sliding plate 503 and improves the stability of the sliding plate 503 during movement. The sliding rod 507 limits the return spring 502 when the return spring 502 is compressed, avoiding damage to the return spring 502 due to excessive bending.

[0032] The inner wall of the arc-shaped plate 1 is fixedly provided with a rubber ring 15. The inner wall of the arc-shaped plate 1 is fixedly provided with two arc-shaped rubber pads 16. The inner wall of the rubber ring 15 is fixedly connected to the surface of the fixed tube 3. On both sides of the back of the arc-shaped plate 1, rubber blocks 17 are fixedly provided. The fronts of the two rubber blocks 17 are respectively fixedly connected to the backs of the two arc-shaped rubber pads 16. The rubber ring 15 fits the lips, and the arc-shaped rubber pads 16 fit the cheeks, avoiding the skin from contacting the hard arc-shaped plate 1 and improving the comfort during use.

[0033] The surface of the fixed tube 3 is fixedly provided with an adjusting seat 18. A threaded hole 19 is opened on the surface of the adjusting seat 18. The inner wall of the threaded hole 19 is threadedly connected with a screw rod 20. One end of the screw rod 20 is fixedly provided with a turntable 21. The other end of the screw rod 20 is rotatably connected with a clamping block 22 through a sealed bearing. The clamping block 22 is used for clamping the intubation tube passing through the fixed tube 3. By rotating the turntable 21, the turntable 21 will drive the screw rod 20 to rotate. The screw rod 20 rotates and moves downward at the same time. By pushing the clamping block 22 and the anti-slip pad downward through the screw rod 20, the anti-slip pad presses the intubation tube inside the fixed tube 3 to fix the intubation tube, which is very convenient.

[0034] The inner wall of the clamping block 22 is fixedly provided with an anti-slip pad. The surface of the clamping block 22 is fixedly provided with two guide rods 23. The contact parts of the two guide rods 23 and the screw rod 20 with the fixed tube 3 are all slidably connected. The contact parts of the two guide rods 23 with the adjusting seat 18 are all slidably connected. The anti-slip pad increases the friction coefficient and improves the stability of the intubation tube clamped by the clamping block 22. The guide rods 23 guide the movement of the clamping block 22.

[0035] During use, first insert the fixed tube 3 into the child's oral cavity, and make the rubber ring 15 fit the lips and the arc-shaped rubber pads 16 fit the cheeks. The bite tube 12 slides into the oral cavity. At this time, the upper and lower jaw teeth respectively fit the two dental pads 26. The dental pads 26 are elastic and protect the upper and lower jaw teeth. Then pinch the end of the bandage 9 and pull the bandage 9 to make the two bandages 9 wind around the child's head. Then bond the male surface 10 of the magic tape to the surface of the female surface 11 of the magic tape, so as to fix the fixing device on the child's face. There is no need to cut multiple sections of adhesive tape during use, which is convenient to use.

[0036] Further, when winding the bandage 9, if the bandage 9 is too long, the length of the extended bandage 9 needs to be adjusted. Specifically, hold the booster frame 509 and push the limit plate 504 to make the limit plate 504 move away from the vertical rod 7, so that the vertical rod 7 disengages from the sliding groove 505 on the surface of the limit plate 504, and the positioning block 14 will disengage from the limit groove 506, releasing the fixation of the limit plate 504 on the vertical rod 7. Rotate the auxiliary rotation cap 13, the auxiliary rotation cap 13 drives the vertical rod 7 to rotate, the vertical rod 7 drives the winding roller 8 to rotate, and the winding roller 8 will wind up the bandage 9, shortening the length of the bandage 9 extending from the storage groove 6. At this time, release the booster frame 509, and the return spring 502 will extend and push the sliding plate 503 and the limit plate 504 to move in the reverse direction, causing the positioning block 14 to snap into the limit groove 506 to complete the fixation of the vertical rod 7. Through the cooperation of the limit assembly 5, the vertical rod 7 and the winding roller 8, the length of the bandage 9 extending can be adjusted, which is convenient for children with different head circumferences to use;

[0037] It should be added that when storing the whole device, rotate the auxiliary rotation cap 13, and the winding roller 8 winds up the bandage 9 inside the storage groove 6 to prevent the bandages 9 of multiple fixing devices from being wound around each other, which is beneficial to centralized storage. The dental pad 26 is elastic and protects the upper and lower jaw teeth. Remove the plastic screw 24, and then remove the movable seat 25 and the dental pad 26. Children under 1 year old do not need the dental pad 26, while children over 1 year old need the dental pad 26. Therefore, through the cooperation of the plastic screw 24, the movable seat 25 and the dental pad 26, the dental pad 26 can be disassembled and installed according to needs, which is suitable for children of different ages to use.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
