Description

Technical Field

[0001] The utility model relates to the field of animal dissection experimental instruments, in particular to a mouse fixing device used in dissection laboratories. Background Art

[0002] At present, in clinical practice, mice are often tested. Mice are a common experimental animal in medical research and are also commonly used in experiments in medical physiology, pharmacology, pathology, pathophysiology and other disciplines. In the dissection experiment of mice, a fixation device is needed to fix the mice. The commonly used fixation devices are a fixation board and multiple sets of thin ropes. Usually, researchers directly place the mice on the fixation board and then use the thin ropes to fix the mouse's limbs before performing anesthesia, dissection and other experimental operations.

[0003] However, in actual use, it was found that the current fixing device still has the following technical problems: the current fixing device is to fix the limbs of the mouse by means of a thin rope, and the thin rope needs to be manually operated to tie a knot to complete the fixation, which is cumbersome to operate, and whether the knot is fixed or not depends on the experimenter who operates it. When tying the knot, it is easy to cause unstable binding and unstable knotting, resulting in poor fixing effect. In addition, the experimenter needs to use both hands to tie the knot, which is not convenient for the experimenter to operate, thereby reducing the efficiency of the experiment and having poor practicality. Utility Model Content

[0004] The utility model aims to provide a mouse fixing device for anatomy laboratory, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 4 The mouse fixation device shown in the figure for an anatomical laboratory includes a fixing plate 1, the fixing plate 1 is connected to a clamping device, the clamping device includes a mounting plate 8, the mounting plate 8 is slidably connected to the fixing plate 1, the mounting plate 8 is connected to a positioning plate 5, the positioning plate 5 is connected to a limiting cylinder 2, a square through groove 11 is provided on the inner side of the limiting cylinder 2, the positioning plate 5 is provided with a through groove 15, the positioning plate 5 is connected to a binding belt 6, the binding belt 6 is connected to a soft pad 16, the free end of the binding belt 6 is connected to a limiting strip 9, the limiting strip 9 and the abdominal band can pass through the through groove 15, the limiting strip 9 is slidably connected to the square through groove 11, as shown in FIG. Figure 2 As shown, the left end of the limit bar 9 can pass through the limit barrel 2. The limit bar 9 is connected to ratchet teeth 10, which are provided in multiple groups. The limit barrel 2 is rotatably connected to a rotating rod 14, which is connected to a pawl 12. The pawl 12 is located inside a square slot 11 and cooperates with the ratchet teeth 10. The pawl 12 is connected to a spring 13, which is connected to the side wall of the square slot 11. There are multiple groups of clamping devices. These groups of clamping devices can clamp and secure different limbs of the mouse. The rotating rod 14 is connected to a toggle plate, and the toggle rod 17 is located outside the limit barrel 2.

[0021] The following Figure 2 and Figure 3 Taking the example of tightening and loosening the binding belt 6 as an example, the following is further described: Figure 2 As shown, in daily use, the limit strip 9 passes through the groove 15 and the square slide, and a binding and fixing space is formed between the binding belt 6 and the positioning plate 5. When binding, the mouse limbs can be placed between the binding belt 6 and the positioning plate 5. When the limit strip 9 is as shown in FIG. Figure 2 In the state shown, the pawl 12 is stably inserted between the two ratchet teeth 10 under the action of the spring 13. At this time, the limit bar 9 can slide directly to the left but cannot slide to the right. The limit bar 9 slides to the left, tightening the belly band, so that the mouse limbs are fixed to the positioning plate 5 by the binding belt 6. After the binding is completed, due to the cooperation of the ratchet teeth 10, the pawl 12 and the spring 13, the pawl 12 is again stuck between the two adjacent groups of ratchet teeth 10 under the action of the elastic force of the spring 13, so that the limit bar 9 and the belly band are in the same state. It is impossible to move right relative to the limiting cylinder 2, thereby completing the stable binding of the mouse's limbs; when contact and fixation are required, the toggle plate is rotated clockwise, thereby driving the rotating rod 14 to rotate clockwise, and the pawl 12 is fixedly connected to the rotating rod 14, so that the pawl 12 will rotate clockwise with the rotating rod 14, thereby causing the pawl 12 to rotate away from between the two adjacent groups of ratchet teeth 10, thereby allowing the limiting bar 9 to move right relative to the limiting cylinder 2, and then contact the binding belt 6 to bind and fix the mouse's limbs.

[0022] The fixing plate 1 is provided with a limiting groove 3, and the mounting plate 8 is slidingly connected to the limiting groove 3. The limiting groove 3 can be used to limit the mounting plate 8 in rotation. The fixing plate 1 is rotatably connected to a threaded rod 4, and the mounting plate 8 is threadedly connected to the threaded rod 4; a dust removal hole 7 is provided at the bottom of the limiting groove 3; the threaded rod is connected to a twisting block, which facilitates the user to rotate the threaded rod 4.

[0023] By twisting the threaded rod 4, the limiting groove 3 acts as a rotation limit for the mounting plate 8. Therefore, as the threaded rod 4 rotates, the mounting plate 8 will move along the threaded rod 4, thereby adjusting the position of the clamping device on the fixed plate 1, completing the position adjustment between the clamping device and other clamping devices, and thus can clamp mice of different sizes.

[0024] The specific implementation process is as follows:

[0025] When using, place the fixing plate 1 on the test bench, screw the corresponding threaded rod 4 to adjust the position of the mounting plate 8, and then pass the limiting strip 9 through the through slot 15 and the direction slide slot, so that the limiting strip 9 slides out of the square slide slot, and a binding space is formed between the binding belt 6 and the positioning plate 5. Place the mouse on the fixing plate 1, and then put the mouse's limbs into the space between the binding belt 6 and the positioning plate 5. Pull the limiting strip 9 according to the above operating steps to tighten the abdominal band and thus complete the binding and fixation of the mouse's limbs. Similarly, the fixation of the other limbs of the mouse can be completed in sequence, and then the mouse is fixed on the fixing plate 1; when you want to remove the mouse later, you only need to rotate the toggle rod 17, and then slide the limiting strip 9 out of the square through slot 11 and the through slot 15; when cleaning the fixing plate 1, the garbage and impurities in the limiting slot 3 can fall out along the dust removal hole 7, which is convenient for cleaning and use.

[0026] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
