Description

Technical Field

[0001] This invention belongs to the field of mouse experimental technology, and in particular relates to a mouse fixation plate. Background Technology

[0002] Laboratory mice have a wide range of applications, including gene research, disease models, drug development, and safety and toxicity testing. In order to ensure the accuracy and safety of experimental operations, it is usually necessary to fix the limbs of laboratory mice to keep them in a supine position so that various experimental operations can be performed.

[0003] However, traditional methods of fixing laboratory mice often use simple fixation plates combined with restraint straps. This method has significant limitations. It lacks the necessary flexibility and adaptability, making it difficult to meet the fixation needs of mice of different sizes and in different experimental scenarios. Furthermore, for laboratory mice of different lengths, traditional fixation methods often cannot accurately adjust the restraint position. This may not only cause discomfort to the mice during fixation, but may also affect the accuracy of experimental results due to improper restraint. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a mouse restraint plate that allows for easy adjustment of the restraint position according to mice of different lengths, thereby improving the convenience and adaptability of experimental operations.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a laboratory mouse fixation plate, comprising a fixation plate, the top of which has four adjustment holes, and the bottom of which has two symmetrically arranged movable frames, each movable frame including a horizontal plate, with sliding plates on both sides of the horizontal plate, the bottom wall of the fixation plate having a bidirectional threaded rod connecting the two horizontal plates via a fixing block, the side wall of the sliding plate having a stepped plate, and a fixing elastic band connected to the stepped plate passing through the adjustment holes.

[0006] By adopting the above technical solution, through structures such as adjustment holes, fixing rubber bands, movable frames and bidirectional threaded rods, flexible fixation and adjustment of experimental mice can be achieved, making it convenient to adjust the restraint position according to mice of different body lengths, thereby improving the convenience and adaptability of experimental operations.

[0007] Optionally, the top of the sliding plate is provided with two sliders, and the bottom of the fixed plate is provided with guide grooves located on both sides of the adjustment hole, and the sliders are slidably connected inside the guide grooves.

[0008] By adopting the above technical solution, the sliding plate can slide smoothly at the bottom of the fixed plate through the setting of slider and guide groove. This design helps to adjust the position of the fixed rubber band binding the mouse's limbs as needed during the experiment, thereby further enhancing the adaptability and flexibility of the fixed plate in fixing experimental mice.

[0009] Optionally, the bidirectional threaded rod is provided with two limiting ring plates on its exterior, and the two limiting ring plates are respectively in contact with the two side walls of the fixing block on opposite sides.

[0010] The setting of the limiting ring plate ensures that the bidirectional threaded rod will not fall off the fixing block during rotation, thereby improving the stability and reliability of the entire fixing plate. This helps to keep the mouse in a fixed state during the experiment and avoid accidents.

[0011] Optionally, a handle is provided at one end of the bidirectional threaded rod, and a stop is provided at the end of the bidirectional threaded rod away from the handle.

[0012] By adopting the above technical solution, the handle allows the operator to more easily rotate the bidirectional threaded rod, thereby achieving rapid adjustment of the sliding plate. The stop prevents the bidirectional threaded rod from extending excessively during rotation, protecting the structural integrity of the entire fixed plate.

[0013] Optionally, the stepped plate includes four single plates distributed at equal intervals, with the side of the single plate away from the sliding plate tilting downwards.

[0014] The stepped board is designed with equal spacing at the top and bottom and tilted downwards, making it easy to hang one end of the fixing elastic band on the stepped board. The lower you hang it, the tighter the fixing elastic band becomes, which makes it easy to adjust the tightness of the fixing elastic band on the mouse's limbs as needed.

[0015] Optionally, the side wall of the sliding plate is provided with a limiting cover plate located above the step plate, and one end of the fixing rubber band passes through the adjustment hole and the limiting cover plate in sequence and is hung on the step plate.

[0016] The limiting cover further restricts the range of motion of the fixing rubber band. After fixing the mouse's limbs, the fixing rubber band can be twisted several times before being hung on the step board. After twisting, the aperture becomes smaller, thereby tightening the mouse's limbs and making the rubber band less likely to slip off, thus preventing the rubber band from accidentally falling off or loosening during the experiment.

[0017] Optionally, the sliding plate is an "L" shaped plate, and the sliding plates on the left and right sides are symmetrically arranged.

[0018] The "L"-shaped sliding plate design not only enhances the stability of the sliding plate but also allows it to better match the bottom structure of the fixed plate. The symmetrical arrangement of the left and right sliding plates ensures the balance and symmetry of the entire fixed plate.

[0019] Optionally, the four adjustment holes are arranged in a matrix, and the adjustment holes are elongated holes with a width smaller than the width of the sliding plate.

[0020] The matrix distribution of the adjustment holes allows the fixing elastic bands to be more flexibly distributed around the experimental mice, thereby improving the flexibility and adaptability of fixation. The setting that the width of the adjustment holes is smaller than the width of the sliding plate prevents the sliding plate from accidentally falling off or becoming misaligned during movement.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. By using structures such as adjustment holes, fixing rubber bands, movable frames, and bidirectional threaded rods, flexible fixation and adjustment of experimental mice are achieved, making it convenient to adjust the restraint position according to mice of different lengths, thereby improving the convenience and adaptability of experimental operations; 2. The design of the stepped board with equidistant distribution and downward inclination makes it easy to hang one end of the fixing rubber band on the stepped board. The lower the fixed rubber band is hung, the tighter the restraint becomes, thus making it convenient to adjust the tightness of the fixing rubber band restraining the mouse's limbs according to needs; 3. After fixing the mouse's limbs, the fixing rubber band can be twisted several times before being hung on the stepped board. After twisting, the aperture becomes smaller, thereby tightening the mouse's limbs and making the rubber band less likely to slip off, further improving the stability of fixation.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figure 1 As shown in Figure 4, the specific scheme of the embodiment is as follows: A mouse fixation plate includes a fixation plate 1. The top of the fixation plate 1 has four adjustment holes 101. The bottom of the fixation plate 1 is symmetrically arranged with two movable frames 5. The movable frames 5 include a horizontal plate 501. Both sides of the horizontal plate 501 are provided with sliding plates 502. The sliding plates 502 are "L" shaped plates. The left and right sliding plates 502 are symmetrically arranged. The bottom wall of the fixation plate 1 is provided with a bidirectional threaded rod 4 that connects the two horizontal plates 501 through a fixing block 3. One end of the bidirectional threaded rod 4 is provided with a handle 6. The end of the bidirectional threaded rod 4 away from the handle 6 is provided with a stop block 9. The side wall of the sliding plate 502 is provided with a stepped plate 7. The adjustment hole 101 is a long strip-shaped hole through which a fixing elastic band 2 connected to the stepped plate 7 passes.

[0030] Please see Figure 1 The four adjustment holes 101 are arranged in a matrix, and the width of the adjustment holes 101 is smaller than the width of the sliding plate 502.

[0031] The matrix distribution of the adjustment holes 101 allows the fixing elastic bands 2 to be distributed more flexibly around the experimental mice, thereby improving the flexibility and adaptability of fixation. The setting that the width of the adjustment holes 101 is smaller than the width of the sliding plate 502 prevents the sliding plate 502 from accidentally falling off or becoming misaligned during movement.

[0032] The handle 6 allows the operator to more easily rotate the bidirectional threaded rod 4, thereby enabling rapid adjustment of the sliding plate 502. The stop block 9 prevents the bidirectional threaded rod 4 from extending excessively during rotation, protecting the structural integrity of the entire fixed plate 1.

[0033] Meanwhile, the design of the "L"-shaped sliding plate 502 not only enhances the stability of the sliding plate 502, but also allows the sliding plate 502 to better match the bottom structure of the fixed plate 1. The symmetrical arrangement of the left and right sliding plates 502 ensures the balance and symmetry of the entire fixed plate 1.

[0034] It should be noted that the structure of adjusting hole 101, fixing rubber band 2, moving frame 5 and bidirectional threaded rod 4 enables flexible fixation and adjustment of experimental mice, making it convenient to adjust the restraint position according to mice of different body lengths, thereby improving the convenience and adaptability of experimental operation.

[0035] Please see Figure 2 In this embodiment, the top of the sliding plate 502 is provided with two sliders 503, and the bottom of the fixed plate 1 is provided with guide grooves 102 located on both sides of the adjustment hole 101. The sliders 503 are slidably connected inside the guide grooves 102.

[0036] The slider 503 and guide groove 102 enable the sliding plate 502 to slide smoothly at the bottom of the fixing plate 1. This design helps to adjust the position of the fixing elastic band 2 binding the mouse's limbs as needed during the experiment, thereby further enhancing the adaptability and flexibility of the fixing plate 1 in fixing the experimental mouse.

[0037] It is worth mentioning that the bidirectional threaded rod 4 is provided with two limiting ring plates 41 on its exterior, with the two limiting ring plates 41 respectively contacting the two side walls of the fixing block 3 on opposite sides. The setting of the limiting ring plates 41 ensures that the bidirectional threaded rod 4 will not fall off the fixing block 3 during rotation, thereby improving the stability and reliability of the entire fixing plate 1. This helps to keep the mouse in a fixed state during the experiment and avoid accidents.

[0038] Please see Figure 2 , Figure 3 In this embodiment, the step plate 7 includes four single plates distributed at equal intervals. The side of the single plate away from the sliding plate 502 is inclined downward. The side wall of the sliding plate 502 is provided with a limiting cover plate 8 located above the step plate 7. One end of the fixing rubber band 2 passes through the adjustment hole 101 and the limiting cover plate 8 in sequence and is hung on the step plate 7.

[0039] Please see Figure 3 , Figure 4The stepped plate 7, with its equidistant, downward-sloping design, facilitates hanging one end of the fixing elastic band 2 onto it. The lower the plate, the tighter the binding, allowing for easy adjustment of the elastic band's tightness around the mouse's limbs. The limiting cover 8 further restricts the movement of the fixing elastic band 2. After securing the mouse's limbs, the elastic band 2 can be twisted several times before being hung back onto the stepped plate 7. Twisting reduces the aperture, further tightening the binding and preventing slippage, thus preventing accidental detachment or loosening during experiments.

[0040] The working principle of the above embodiment is as follows: After placing the experimental mouse supine with its abdomen facing up on the top of the fixing plate 1, the mouse's four limbs are sequentially threaded through the four fixing rubber bands 2. Then, one end of the fixing rubber band 2 is flipped over and hung on a suitable step plate 7. The lower the fixing rubber band 2 is hung, the tighter it becomes, so as to facilitate the adjustment of the tightness of the fixing rubber band 2 in fixing the mouse's limbs as needed. When fixing experimental mice of different lengths, the star handle 6 is rotated clockwise or counterclockwise to drive the bidirectional threaded rod 4 to rotate, so that the moving frames 5 on both sides can move relative to each other or in opposite directions, and the position of the fixing rubber band 2 can be adjusted as needed.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
