[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0022] In addition, in the present utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present utility model. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0023] Embodiment 1:
[0024] The embodiment of the utility model provides a rat tail blood sampling and injection fixing device, such as Figure 1-6 As shown, it includes a rat tail fixing platform 1, the front end of the rat tail fixing platform 1 is connected to a front clamping block 2, and the rear end is connected to a rear clamping block 3, the front clamping block 2 is connected to the rat tail fixing platform 1 through a first screw 4, and the rear clamping block 3 is connected to the rat tail fixing platform 1 through a second screw 5.
[0025] The working principle and beneficial effects of the above technical solution are as follows: by adjusting the first screw 4 and the second screw 5, the front clamping block 2 and the rear clamping block 3 can be pushed toward the rat tail, thereby achieving fixation of rat tails of different thicknesses.
[0026] Embodiment 2:
[0027] On the basis of the above-mentioned embodiment 1, Figure 1-6 As shown, the lower part of the rat tail fixing platform 1 is a base 101, and four first through holes 102 are arranged on the base 101. The upper part of the rat tail fixing platform 1 is provided with a rat tail channel 103. The front end of the rat tail channel 103 is connected to a front slide 105 to the outside of the side, and two first screw holes 104 are distributed on both sides of the front slide 105. The rear end of the rat tail channel 103 is connected to a rear slide 107 to the outside of the side, and two second screw holes 106 are distributed on both sides of the rear slide 107.
[0028] The working principle and beneficial effects of the above technical solution are as follows: when conducting a rat tail puncture experiment, the rat tail fixing platform 1 is fixed on the experimental platform through the four first through holes 102 on the base 101, which is conducive to the stability of the fixing device during the experiment. The rat tail channel 103 is used to place the rat tail, and the rat tail is placed from the front end to the rear end along the rat tail channel 103. The front slide 105 is matched with the front clamping block 2, and the front clamping block 2 can slide on the front slide 105. The rear slide 107 is matched with the rear clamping block 3, and the rear clamping block 3 can also slide on the rear slide 107, so that it can be ensured that there is enough space to accommodate rat tails of different thicknesses. Since the thickness of the rat tail decreases from front to back, the rear end of the rat tail channel 103 can be set narrower than the front end, which is conducive to the fixation of the rear end of the rat tail. The rat tail puncture site is located in the middle section of the rat tail channel 103. This section of the channel is lower than the front and rear ends, which can ensure that the rat tail protrudes from the highest surface of the middle section of the rat tail channel 103 after being placed. This ensures that the puncture action can be well performed regardless of manual puncture or automatic puncture by the device under ultrasound guidance.
[0029] Embodiment 3:
[0030] On the basis of the above-mentioned embodiments 1-2, Figure 1-6 As shown, the front slide 105 and the rear slide 107 are located on the same side of the rat tail channel 103 .
[0031] The working principle and beneficial effects of the above technical solution are: the user performs related operations on the same side, the operation process is simple, and such a design structure is more reasonable, which can ensure that the mouse tail is overall leaning to the same side after being fixed and the mouse tail is on the same line.
[0032] Embodiment 4:
[0033] Based on the above embodiments 1-3, Figure 1-6 As shown, a first slide slot 202 is provided in the middle of the front clamping block 2, and second through holes 201 are distributed on both sides of the first slide slot 202. A second slide slot 302 is provided in the middle of the rear clamping block 3, and third through holes 301 are distributed on both sides of the second slide slot 302.
[0034] The working principle and beneficial effects of the above technical solution are as follows: the first slide groove 202 in the middle of the front clamping block 2 cooperates with the front slide 105, the first screw 4 passes through the second through hole 201 and is connected to the first screw hole 104, and the degree of clamping between the front clamping block 2 and the mouse tail can be achieved by adjusting the first screw 4. Similarly, the second slide groove 302 in the middle of the rear clamping block 3 cooperates with the rear slide 107, the second screw 5 passes through the third through hole 301 and is connected to the second screw hole 106, and the degree of clamping between the rear clamping block 3 and the mouse tail can be achieved by adjusting the second screw 5. The cross-sections of the first slide groove 202 and the second slide groove 302 can be square or circular, as long as they are conducive to sliding.
[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
