[0027] Referring to the attached Figure 1 , the embodiments of the present application provide an auxiliary fixing table 2 for rat tracheal intubation operation, including a support table 1 and a fixing table 2. The support table 1 is horizontally arranged, the fixing table 2 is integrally formed with the support table 1, and an included angle of 45 degrees is formed between the fixing table 2 and the support table 1. The fixing table 2 is provided with fixing members 3 for fixing the four limbs of the rat and a spreading member 4 for spreading the oral cavity of the rat. It can be imagined that during the experiment, by horizontally placing the support table 1 and using the inclined fixing table 2 to fix the rat, it is convenient to see the internal structure of the rat's oral cavity.

[0028] In one embodiment, as a conventional structure for fixing the limbs of a rat, the fixing member 3 can be a binding rope, which is used to fix the limbs of the rat by binding; of course, the fixing member 3 can also adopt a buckle structure, which usually includes a buckle arranged on the fixing platform 2 and a hook with one end movably hinged to the buckle, and the limbs of the rat are locked by putting the limbs of the rat into the buckle and buckling the hook with the buckle. It can be seen that the anesthetized rat can be fixed on the fixing platform 2 in a spread-eagle position by the fixing member 3.

[0029] See above Figure 2 As shown, the propping member 4 includes a bracket 41, a horizontal plate 43 and a fastener 45. Among them, the bracket 41 includes a bottom plate 410 and a door post 411, and the door post 411 includes an upper door post and a lower door post that are plugged into each other. The upper door post and the lower door post are plugged into each other, and an adjustment bolt for pressing the upper door post and the lower door post is provided. The bottom plate is a pair of fixed to the fixed platform 2 and arranged on both sides of the rat's head and neck. The door post is fixed to the bottom plate, and a pair of horizontally adjustable horizontal plates 43 are arranged between the door posts. Specifically, the door post is connected to one of the horizontal plates 43 by a connecting arm 42, and the other horizontal plate 43 is arranged on the opposite side. Of course, in this embodiment, in order to achieve an adjustable spacing between the two horizontal plates 43, an adjustment member 44 is also provided between the two horizontal plates 43, and the adjustment member 44 includes a guide column 440, a spring 441 and an adjustment end 442. A pair of parallel guide posts 440 are arranged between the two horizontal plates 43. One end of the guide posts 440 is fixedly connected to the horizontal plate 43 on one side of the connecting arm 42, and the horizontal plate 43 on the other side is provided with a through hole for the guide posts 440 to pass through. The guide posts 440 are slidably connected to the horizontal plate 43 on the other side by passing through. At the same time, a spring 441 is sleeved on the guide posts 440 between the two horizontal plates 43. The spring 441 is in a compressed state in a natural state. A threaded section is arranged at one end of the guide posts 440 located on the sliding side horizontal plate 43, and an adjusting end 442 is threadedly connected to the threaded section. By screwing the adjusting end 442 inward or outward, the tightness of the spring 441 is adjusted, thereby adjusting the spacing between the two horizontal plates 43.

[0030] In the above embodiments, the two transverse plates 43 are disconnected in the middle, and the fastener 45 is rotatably arranged at the disconnection between the transverse plates 43. Specifically, the fastener 45 includes a sleeve 450, a tightening rope 451 and a tightening head 452. Among them, both sides of the sleeve 450 are connected to the disconnection of the transverse plate 43 through a rotating shaft 46, and the rotating shaft 46 is rotatably connected to the transverse plate 43. The sleeve 450 is fixed to the rotating shaft 46. At the same time, a locking bolt 47 is arranged on the transverse plate 43. The locking bolt 47 is screwed in to press the rotating shaft 46 to prevent the sleeve 450 from rotating, and the sleeve 450 can be loosened for rotation by screwing out the locking bolt 47. A group of wire holes are arranged along the length direction of the sleeve 450. The tightening rope 451 penetrates from the upper side wire hole downward and then penetrates from the lower side wire hole upward. In this way, the tightening rope 451 forms a noose with the sleeve 450 below. By pulling up the two rope ends of the tightening rope 451, the noose can be tightened to tighten the upper and lower jaws of the rat; the tightening head 452 is provided with a pair of guiding holes, and the two rope ends of the tightening rope 451 pass through the guiding holes. Since the inner diameter of the guiding hole is smaller than the outer diameter of the tightening rope 451, by sliding the tightening head 452 to fit the upper end of the transverse plate 43, the tightening length of the tightening rope 451 can be locked. And since the rat is in an anesthetized state during tracheal intubation, the tightening head 452 is sufficient to lock the tightening rope 451 and prevent it from being randomly pulled to change the tightness of the tightening.

[0031] In a preferred embodiment, in order to ensure that the rat's face is upward, as shown in Figure 1 shown, a restraining strap for restraining the rat's neck is further arranged on the fixing table 2. The restraining strap binds the rat's neck to the fixing table 2, so that the rat's face is upward, which is convenient for observing the internal structure of the rat's oral cavity.

[0032] In summary, for an auxiliary fixing table 2 for rat tracheal intubation operation provided by the embodiment of the present application, its usage method is as follows:

[0033] First, fix the anesthetized rat in a large character shape on the fixing table 2 through the fixing member 3;

[0034] Then rotate the sleeve 450 to be parallel to the fixing table 2 and lock the locking bolt 47. Put the two tightening ropes 451 around the upper and lower jaws of the rat respectively, and lift the tightening ropes 451 to tighten and fasten the noose, and use the tightening head 452 to lock the tightening ropes 451;

[0035] Then rotate the adjusting end 442 outwards. Since the spring 441 is in a compressed state, under the action of the spring 441, the transverse plate 43 slides to increase the distance between the two transverse plates 43. Thus, the movement of the transverse plate 43 drives the tightening ropes 451 to open the upper and lower jaws of the rat to expose the rat's oral cavity, which is convenient for the operator to perform intubation.

[0036] It can be seen that the utility model provides an auxiliary fixing table for the tracheal intubation operation of rats, with a simple structure, which provides convenience for helping experimenters to complete the tracheal intubation operation of rats more simply and safely through the neck transillumination method.

[0037] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
