Detailed implementation mode

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0029] As Figure 1 shown, a tracheal intubation anti-biting tube fixator includes a body 1, a pressing block 2 vertically slidably arranged on one side of the body 1, and a fixing bracket 3 fixed outside the body 1. The body 1 has a vertical cylindrical or elliptical cylindrical structure, and its upper end is an insertion end (the end inserted into the mouth). The fixing bracket 3 is arranged at the middle and lower part of the body 1. A central hole 11 for placing the tracheal intubation is penetrated through the axis of the body 1. The aperture of the central hole 11 is adapted to the outer diameter of the tracheal intubation. A card slot 13 is vertically opened on one side of the body 1. The upper and lower ends of the card slot 13 penetrate through the upper and lower end faces of the body 1, and the card slot 13 horizontally penetrates through the body 1 and communicates with the central hole 11. The tracheal intubation is clamped into the central hole 11 through the card slot 12. The pressing block 2 is vertically slidably arranged in the card slot 13, and the pressing block 2 presses the tracheal intubation to further fix the tracheal intubation.

[0030] The structure of the card slot 13 is as Figure 2 , 3 shown, and it includes a first slot part 131 and a second slot part 132 arranged in sequence and adjacent to each other along the radial direction of the body 1. The side walls of the first slot part 131 and the second slot part 132 are both vertical surfaces, and the side walls of the first slot part 131 and the second slot part 132 form an outwardly convex sharp corner structure 133 at the connection. Preferably, both the first slot part 131 and the second slot 132 adopt a V-shaped slot structure. The first slot part 131 is a V-shaped slot with an opening facing the center of the body 1, and the second slot part 132 is a V-shaped slot with an opening facing outward. At this time, the slot walls of the first slot part 131 and the second slot part 132 form the above-mentioned sharp corner structure 133 at the connection.

[0031] The structure of the pressing block 2 is as Figure 4 , Figure 5 and Figure 6As shown, the outer surface 24 of the pressing block 2 is an outwardly convex arc surface, and the inner surface 23 thereof is an inwardly concave arc surface, the shape of the inwardly concave arc surface corresponds to the surface of the tracheal tube, and the inner surface 23 is tilted, and the tilting direction is: its upper end tilts outward, that is, toward the outer surface of the pressing block 2. This structure makes the inner surface 23 of the pressing block 2 a vertically wedge-shaped surface structure, and because the inner surface 23 of the pressing block 2 corresponds to the tracheal tube in the central hole 11 of the body 1, a wedge-shaped locking structure is formed between the pressing block 2 and the tracheal tube, that is, when the pressing block 2 is inserted from the lower end of the card slot 13 and pushed upward, the pressing block 2 will gradually press and fix the tracheal tube. In order to guide the pushing direction of the pressing block 2 and prevent the pressing block 2 from falling out of the slot, the left and right side surfaces of the pressing block 2 are adapted to the slot walls of the slot 13, that is, the left and right side surfaces of the pressing block 2 are respectively concave with grooves 21 corresponding to the sharp angle structure 133, and the sharp angle structure 133 and the groove 21 are assembled to form an anti-falling structure for preventing the pressing block 2 from falling out of the slot 13. At the same time, the structure also guides the movement of the pressing block 2 in the slot 13 to ensure that the pressing block 2 moves axially along the body 1, so as to ensure that the pressing block 2 and the endotracheal tube form a wedge-shaped locking structure.

[0032] In the utility model, a plurality of avoidance grooves 12 are vertically provided on the wall of the central hole 11 to accommodate other pipelines connected to the endotracheal tube, such as the airbag inflation tube, the sputum suction tube, etc., to prevent the other pipelines in the body and the endotracheal tube from squeezing each other, thereby ensuring that all pipelines are unobstructed.

[0033] In the present invention, the fixing frame 3 and the body 1 are integrally formed. The fixing frame 3 is a semi-annular structure with an opening on one side. The opening position of the fixing frame 3 corresponds to the position of the card slot 13, so as to facilitate the tracheal tube to be installed in the center hole 11 through the card slot 13. The first holes 31 are respectively provided at the left and right ends of the fixing frame 3. The first holes 31 are used to pass a rope or a strap, and then the fixing device is hung on the ear or tied to the head by the rope or strap for fixing, eliminating the need to use tape for fixing, thereby improving the convenience of fixing the tracheal tube. In the present invention, the fixing frame 3 is provided with a second hole 32 at the end away from the opening thereof.

[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 principles of the present invention should be included in the protection scope of the present invention.
