[0028] When in use, after completing the tracheal intubation of the patient, the tracheal intubation needs to be fixed, and the tracheal intubation is placed between the two arc-shaped splints 11, and then the two threaded rods 7 are rotated. The side ends of the two threaded rods 7 are respectively connected to the arc-shaped fixing plates 8 through bearings. When the two threaded rods 7 rotate, the two arc-shaped fixing plates 8 are limited by the slider 10 and the slide groove 9, so they will not rotate with the threaded rods 7, and when the threaded rods 7 rotate, the two threaded rods 7 are engaged with the screw holes 6 and the threaded rods 7, so that the two threaded rods 7 will move. When the two threaded rods 7 move toward each other, they will also drive the two arc-shaped fixing plates 8 and the arc-shaped splints 11 to move toward each other, thereby achieving the fixation of the tracheal intubation between the two arc-shaped splints 11, and reducing the compression and damage to the tracheal intubation through the elastic connection.

The top end of the No. 2 mounting column 16 is hinged with a pressure rod 23, and a pressure block 24 is fixedly connected to the pressure rod 23. The pressure block 24 is located just above the slide rod 19. The No. 1 shell 25 and the No. 2 shell 26 are respectively provided on the opposite side walls of the two gas cylinders 14. The gas cylinder 1 of the flushing assembly 4 is connected with the first shell 25 through a one-way air valve, an air inlet 27 is provided on the side wall of the air cylinder 14 of the flushing assembly, a liquid inlet 28 and a flushing port 29 are provided on the upper surface of the first shell 25, the air cylinder 14 of the drainage assembly is connected with the second shell 26 through a one-way air valve, an air outlet 30 is provided on the side wall of the air cylinder 14 of the drainage assembly, a drainage port 31 is provided on the upper surface of the second shell 26, and a liquid outlet 32 ​​is provided on the side wall of the second shell 26, the support assembly includes a first support plate 33 and a second support plate 34 fixedly connected to the side wall of the support rod 3, and the first support plate 33 and the second support plate 34 are connected to the first support plate 33 and the second support plate 34. 4 are respectively penetrated and slidably connected with No. 2 guide rods 35, and the opposite ends of the two No. 2 guide rods 35 are respectively fixedly connected with arc-shaped support plates 36, and two No. 3 springs 37 are respectively fixedly connected between the two arc-shaped support plates 36 and the bottom surface of the No. 1 support plate 33 and the surface of the No. 2 support plate 34.

The air inlet 27 and the air outlet 30 are both provided with a one-way air valve, and the airflow of the air inlet 27 can only enter but not exit, and the airflow of the air outlet 30 can only exit but not enter;

[0030] When it is necessary to use the flushing or drainage function of the device, the corresponding functional components are used according to the required functions. Taking the flushing component as an example, when the flushing function is needed, the flushing liquid is stored in the No. 1 shell 25 through the liquid inlet 28, and then the flushing pipe is connected through the flushing port 29, and the flushing pipe is supported by the support component. Then, the pressure rod 23 is pressed to make it swing around the hinge point with the No. 2 mounting column 16. At this time, the pressure block 24 will give a pressure to the slide bar 19, so that it moves downward with the piston 22. At this time, the air in the cylinder 14 will be compressed into the No. 1 shell 25. Because the device is used horizontally, after the gas is compressed into the No. 1 shell 25, the pressure will cause the flushing liquid to be discharged from the flushing port 29 and flush the patient's mouth along the flushing pipe. When operating the component, it needs to be pressed repeatedly. The operation is convenient and no additional auxiliary machine is required. The drainage component has the same principle as the flushing component. The air in the No. 2 shell 26 is discharged, and the component has a drainage function through pressure, so as to drain the secretions in the patient's mouth.

[0031] The working principle of the present invention is as follows:

[0032] When in use, after completing the tracheal intubation of the patient, the tracheal intubation needs to be fixed, and the tracheal intubation is placed between the two arc-shaped splints 11, and then the two threaded rods 7 are rotated. The side ends of the two threaded rods 7 are respectively rotatably connected with the arc-shaped fixing plates 8 through bearings. When the two threaded rods 7 rotate, the two arc-shaped fixing plates 8 are limited by the slider 10 and the slide groove 9, so they will not rotate with the threaded rods 7, and when the threaded rods 7 rotate, the two threaded rods 7 are engaged with the threaded rods 7 through the screw holes 6, so that the two threaded rods 7 will move. When the two threaded rods 7 move toward each other, they will also drive the two arc-shaped fixing plates 8 and the arc-shaped splints 11 to move toward each other, thereby achieving the fixation of the tracheal intubation between the two arc-shaped splints 11, and reducing the compression and damage to the tracheal intubation through the elastic connection.

[0033] When it is necessary to use the flushing or drainage function of the device, the corresponding functional components are used according to the required functions. Taking the flushing component as an example, when the flushing function is needed, the flushing liquid is stored in the No. 1 shell 25 through the liquid inlet 28, and then the flushing pipe is connected through the flushing port 29, and the flushing pipe is supported by the support component. Then, the pressure rod 23 is pressed to make it swing around the hinge point with the No. 2 mounting column 16. At this time, the pressure block 24 will give a pressure to the slide bar 19, so that it moves downward with the piston 22. At this time, the air in the cylinder 14 will be compressed into the No. 1 shell 25. Because the device is used horizontally, after the gas is compressed into the No. 1 shell 25, the pressure will cause the flushing liquid to be discharged from the flushing port 29 and flush the patient's mouth along the flushing pipe. When operating the component, it needs to be pressed repeatedly. The operation is convenient and no additional auxiliary machine is required. The drainage component has the same principle as the flushing component. The air in the No. 2 shell 26 is discharged, and the component has a drainage function through pressure, so as to drain the secretions in the patient's mouth.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
