Description

Technical Field

[0001] The utility model relates to the field of mouse experiments, in particular to a limb fixing device for mouse experiments. Background Art

[0002] Laboratory mice usually refer to mice used for scientific research. They are commonly used model organisms in laboratories. Laboratory mice are widely used in research in biology, medicine, genetics, pharmacology, toxicology and neuroscience. Because they have many similarities with humans in genetics and physiology, laboratory mice provide scientists with an important tool for studying human diseases and physiological processes. Before conducting experiments on some mice, the mice's limbs need to be fixed to prevent them from breaking free.

[0003] Traditionally, mice are usually tied and fixed with ropes or rubber bands. However, the fixation with ropes or rubber bands is not only difficult to control the strength, but also easily causes the ropes to be pulled, leaving the mice with a certain amount of space to move. Therefore, a limb fixation device for mouse experiments is proposed to solve the above problem. Utility Model Content

It solves the problem that mice are generally tied and fixed with ropes or rubber bands in traditional situations, but the fixing force of ropes or rubber bands is not only difficult to control, but also easily causes the rope to be pulled, leaving the mice with a certain amount of room for movement.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the embodiment, Figure 1-4 A limb fixing device for mouse experiments is provided. The utility model includes a fixing platform 1, the bottom of the fixing platform 1 is fixedly connected to a tripod 2, and the left and right sides of the fixing platform 1 are fixedly connected to two fixing plates 3 that are symmetrically distributed front to back, and a plurality of makeshift holes are opened inside the four fixing plates 3. Four support frames 4 are respectively located inside the four fixing plates 3 and are clamped inside the two makeshift holes. The tops of the four support frames 4 are fixedly connected to a lower fixing frame 5, and the upper parts of the four lower fixing frames 5 are rotatably connected to an upper fixing frame 6 through a hinge support, and the interiors of the four upper fixing frames 6 are provided with fixing devices 7.

[0028] The four support frames 4 are all U-shaped, and two limiting grooves are provided inside the four support frames 4 .

[0029] In this embodiment, during actual use, the support frame 4 can be placed into the fixing plate 3 along the clearance hole, and at this time the limiting groove is just located below the edge of the fixing plate 3.

[0030] The front and rear sides of the single fixed plate 3 are fixedly connected with extension plates 8 , and the interiors of the two extension plates 8 are slidably connected with limiting plates 9 that penetrate through and extend to the outsides of the two limiting grooves.

[0031] In this embodiment, during actual use, the limiting plate 9 is passed through the two extension plates 8 and the limiting groove. At this time, the support frame 4 cannot be pulled out and the support frame 4 will remain fixed.

[0032] The outer side of the single lower fixing frame 5 and the outer side of the single upper fixing frame 6 are both fixedly connected with a connecting plate 10 , and the interiors of the two connecting plates 10 are both threadedly connected to the second bolt knob 11 .

[0033] In this embodiment, during actual use, the two connecting plates 10 can be connected by the second bolt knob 11 under the action of the thread, thereby keeping the two fixing frames fixed.

[0034] Among them, the single fixing device 7 includes a first bolt knob 71 connected to the internal thread of a single upper fixing frame 6, the bottom of the first bolt knob 71 is rotatably connected to the limit frame 72, and the top of the limit frame 72 is fixedly connected to a limit rod 73 that is slidably connected to the upper fixing frame 6.

[0035] In this embodiment, during actual use, when the first bolt knob 71 is turned, the limit frame 72 will move downward, and the limit rod 73 will limit the moving direction of the limit frame 72. The downward movement of the limit frame 72 will fix the mouse limbs below it.

[0037] In this embodiment, during actual use, the body of the mouse can be fixed by passing the tightening belt 12 through the connection of the tightening buckle 13, thereby further restricting the movement of the mouse.

[0038] Working principle:

[0039] First, press the mouse on the fixing platform 1, and fix the mouse's body by combining the tightening belt 12 and the tightening buckle 13. Then adjust the position of the support frame 4 according to the arm span and length of the mouse, insert the support frame 4 into the clearance hole, and then limit the support frame 4 through the limiting plate 9. Then unscrew the second bolt knob 11, open the upper fixing frame 6, and put the mouse's limbs into it. The combination of the two fixing frames will limit the mouse's limbs, and by turning the first bolt knob 71, the limiting frame 72 can be pressed and fixed to the mouse's limbs.
