[0048] For the technical scheme of the embodiment, the first fixing assembly 7 is mainly used to bind the trachea from the outside, the first fixing assembly 7 comprises a clamping piece 71 fixed to the end of the support seat 6 and a clamping plate 72 connected to the side wall of the connecting plate 5, the side of the clamping plate 72 facing the clamping piece 71 is arranged in a beveled shape, the top of the clamping piece 71 is also provided with a beveled surface adapted to the clamping plate 72, a binding belt 73 is fixedly connected to the side wall of the support seat 6, the other end of the binding belt 73 is a free end, a protrusion is fixedly connected to the bottom of the clamping plate 72, and a groove adapted to the protrusion is formed in the top of the support seat 6, the clamping piece 71 and the clamping plate 72 are made of plastic material and have a certain deformation capacity, when the cannula needs to be bound, the trachea is first attached to the bottom of the support seat 6, then the free end of the binding belt 73 is wound around the trachea to bind the trachea to the bottom of the support seat 6, then the free end of the binding belt 73 is placed between the clamping plate 72 and the top plane of the support seat 6, then the clamping plate 72 is pressed downward to make the protrusion clamp the binding belt 73 in the groove, then the beveled surface of the clamping plate 72 will be in close contact with the beveled surface of the clamping piece 71 and extrude the clamping piece 71 outward, so that the clamping plate 72 is clamped below the clamping piece 71, and the binding belt 73 is fixed, when the cannula needs to be removed, the clamping piece 71 is pulled outward to unlock the clamping plate 72.

[0049] For the technical scheme of the embodiment, the fixing ring 8 is mainly used for fixing and guiding the trachea in the oral cavity of the patient, avoiding the patient's teeth from biting the trachea and causing damage to the trachea. An opening is formed in the outer side wall of the fixing ring 8, and a baffle 17 is arranged at the end of the opening. A clamping strip 18 is fixedly connected to the inside of the fixing ring 8. The outer edge of the opening is arranged as a circular arc to avoid scratching the patient's oral cavity. When the fixing ring 8 is used to fix the trachea, the trachea is first clamped into the inside of the fixing ring 8 from the opening. The baffle 17 prevents the trachea from falling out of the opening, and the clamping strip 18 further clamps the trachea to further enhance the stability of the trachea.

[0050] For the technical scheme of the embodiment, the ends of the two adjusting rings 10 are fixedly connected with the first fixing belt 20 and the second fixing belt 21, respectively. The parts where the first fixing belt 20 and the second fixing belt 21 contact are respectively provided with a Velcro hook surface and a Velcro fleece surface. The first fixing belt 20 and the second fixing belt 21 are used to fix the support ring 1 on the patient's head.

[0051] The number of adjusting rings 10 is two, and the two adjusting rings 10 are respectively located at the two ends of the support ring 1. The top of the adjusting ring 10 is provided with a circular hole 19 matched with the top rod 14. When the top rod 14 is clamped into the circular hole 19, the adjusting ring 10 can be fixed and limited, so as to control the length of the adjusting ring 10 extending out of the accommodating cavity 9. When the top rod 14 is separated from the circular hole 19, the adjusting ring 10 can be unlocked. The length of the adjusting ring 10 can be adaptively adjusted according to the actual situation of the patient, which is convenient for adapting to patients with different faces and head sizes and improving the practicability of the device as a whole.

[0052] It needs to be explained that the top of the extrusion block 12 is fixedly connected with the push rod 22, and the push rod 22 is arranged through the containing cavity 9. The top of the containing cavity 9 is provided with a strip-shaped slot matched with the push rod 22, so as to provide a moving space for the push rod 22. The side of the extrusion block 12 in contact with the top rod 14 is provided in a slope shape. The upper and lower ends of the top rod 14 are both provided in a circular arc surface. The support sleeve 13 is sleeved on the outer surface of the top rod 14. One end of the elastic member 15 is fixed on the top rod 14, and the other end is fixed on the support sleeve 13. In a natural state, the elastic rod 11 is in an elongated state. At this time, the extrusion block 12 will extrude the top rod 14, so that the top rod 14 moves downward and is clamped into the circular hole 19 provided at the top of the adjusting ring 10. At this time, the adjusting ring 10 is in a fixed state. When it is necessary to unlock the adjusting ring 10, the push rod 22 is pushed to drive the extrusion block 12 to move and extrude the elastic rod 11. At this time, the extrusion block 12 will be separated from the top rod 14. Then, the top rod 14 will move upward to reset under the action of the elastic force of the elastic member 15. At this time, the bottom end of the top rod 14 is separated from the circular hole 19, so that the adjusting ring 10 can be unlocked. After the adjusting ring 10 is pulled to move to an appropriate length and the push rod 22 is loosened, the top rod 14 will be clamped into the corresponding circular hole 19 again.

[0053] Specifically, when it is necessary to intubate the trachea of a patient, the trachea is first attached to the bottom of the support seat 6, and then the trachea is bound to the bottom of the support seat 6 by winding the free end of the bandage 73 once. Then, the free end of the bandage 73 is placed between the clamping plate 72 and the bottom of the support seat 6. Then, the clamping plate 72 is pressed downward, so that the protrusions clamp the bandage 73 in the grooves. Then, the inclined surface of the clamping plate 72 will be in contact with the inclined surface of the clamping piece 71, and the clamping piece 71 will be extruded outward. Thus, the clamping plate 72 can be clamped below the clamping piece 71, and the bandage 73 can be fixed, so that the external trachea is fixed. Then, the trachea is clamped into the inside of the fixing ring 8 from the opening of the fixing ring 8. The setting of the baffle 17 can prevent the trachea from falling off from the opening, and the setting of the clamping strip 18 can also clamp the trachea, so as to further enhance the stability of the trachea. Then, the fixing ring 8 is placed in the mouth of the patient. Then, the push rod 22 is pushed to drive the extrusion block 12 to move and extrude the elastic rod 11. At this time, the extrusion block 12 will be separated from the top rod 14. Then, the top rod 14 will move upward to reset under the action of the elastic force of the elastic member 15. At this time, the bottom end of the top rod 14 is separated from the circular hole 19, so that the adjusting ring 10 can be unlocked. After the adjusting ring 10 is pulled to move to an appropriate length and the push rod 22 is loosened, the top rod 14 will be clamped into the corresponding circular hole 19 again. In this way, the length of the adjusting ring 10 can be adaptively adjusted according to the actual situation of the patient, so as to adapt to patients with different face sizes and head sizes, and improve the practicability of the device as a whole. After the adjustment is completed, the device as a whole can be fixed on the head of the patient by using the first fixing belt 20 and the second fixing belt 21.
