Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an experimental mouse skull observation adapter. Background Art

[0002] Rats are widely used in medical and biological research. Nowadays, various microscopes are needed for observation of the living head of rats. When observing rats, the part of the rat that needs to be observed needs to be fixed. However, when fixing rats, it is difficult for existing equipment to fix the main force points of the rats, which can easily lead to the rats struggling through the force points. This not only makes it easy for the rats to break free, but also the fixed parts are prone to friction with the fixed structures during the struggle, thereby causing injuries to the rats. This requires staff to improve their equipment.

[0003] Patent document CN219742971U discloses an experimental mouse head observation adapter, "mainly used in: live observation of experimental mouse heads; by setting: a base plate for carrying experimental mice; an accessory for fixing the head of the experimental mouse and having an observation hole; a support member connecting the accessory to the base plate and driving the accessory to move closer to or away from the base plate; a limit rod connected to the base plate so that the accessory will not rotate relatively when it moves closer to or away from the base plate, and a connecting plate connecting the limit rod to the support member; solves the problem that it is difficult to ensure that the fixed position of the mouse head remains unchanged when repeating the live observation experiment of the experimental mouse head, making it difficult to ensure the accuracy of the experimental results."

[0004] When used, the above-mentioned device can make the accessories act directly up and down on the head of the experimental mouse, thereby achieving the fixed position of the mouse's head; and through the observation hole set on the accessory, the brain nerve cells of the experimental mouse can be observed. However, the white mouse will inevitably struggle after being stimulated by the strong light after being fixed, and the main force point of the white mouse's head struggle is in the neck. The device fixes the head and it is difficult to avoid the struggle of the white mouse, causing the white mouse to fall off the surface of the device, thereby affecting subsequent observations. This requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that an experimental mouse head observation adapter in the prior art is difficult to fix the main force points such as the neck, so that the white mouse can fall off by struggling, thereby providing an experimental mouse head observation adapter.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A base, one side of the top of the base is rotatably connected to a protective plate, the inner wall of the protective plate is slidably connected to a baffle, the inner wall of the baffle is threadedly connected to a first threaded rod, and the surface of the first threaded rod is rotatably connected to the surface of the protective plate, one end of the first threaded rod is fixedly connected to a first hand wheel, and one side of the first hand wheel is rotatably connected to one side of the baffle, the other end of the threaded rod is fixedly connected to a gasket, and the surface of the gasket is rotatably connected to the inner wall of the protective plate.

[0009] As an optional technical solution, a connecting groove is provided on one side of the base, and a placement groove is provided on the inner wall of the base.

[0010] As an optional technical solution, a card slot is provided at the bottom of the protective plate, and a card block is slidably connected to the inner wall of one side of the base.

[0011] As an optional technical solution, a spring is fixedly connected to one side of the clamping block, and a push plate is fixedly connected to the surface of the clamping block.

[0012] As an optional technical solution, a rubber pad is fixedly connected to one side of the top of the base, and threaded sleeve rods are fixedly connected to both sides of the top of the base.

[0013] As an optional technical solution, the inner wall of the threaded sleeve is threadedly connected to a second threaded rod, and the top end of the second threaded rod is rotatably connected to a pressure plate.

[0014] As an optional technical solution, the top end of the second threaded rod is fixedly connected to a second hand wheel, and both sides of the bottom of the pressure plate are fixedly connected to arc plates.

[0015] The utility model technical solution has the following advantages:

[0016] 1. The utility model rotates the first hand wheel, and the rotation of the first hand wheel drives the baffle plate on the surface to move. The two sets of baffle plates move relatively in the protective plate, so as to fix the neck of the white mouse, so as to avoid the situation that the white mouse is stimulated to twist its neck and cause the position of the head to deviate when the head of the white mouse is observed. In addition, fixing the neck and head of the white mouse at the same time can effectively prevent the white mouse from struggling greatly. Since the neck of the white mouse is fixed, the part below the neck of the white mouse can move normally, reducing the pain of the white mouse, thereby improving the comfort of the white mouse during observation.

[0017] 2. The utility model fixes the torso of the white mouse by placing the white mouse in the placement groove and then fixing the protective plate to the surface of the base. The torso of the white mouse can also move freely after being fixed in the protective plate. After the torso of the white mouse is fixed, the situation that the white mouse is stimulated and scratches the staff can be avoided. The connecting groove on one side of the protective plate and the base can provide a certain activity space for the tail of the white mouse. When injecting drugs into the white mouse, part of the drugs are injected at the tail, and the device can provide a better angle for the injection. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Reference Figure 1 , Figure 3 and Figure 6 As shown, an experimental mouse skull observation adapter comprises: a base 1, a protective plate 2 is rotatably connected to one side of the top of the base 1, a baffle 3 is slidably connected to the inner wall of the protective plate 2, a first threaded rod 4 is threadedly connected to the inner wall of the baffle 3, and the surface of the first threaded rod 4 is rotatably connected to the surface of the protective plate 2, one end of the first threaded rod 4 is fixedly connected to a first hand wheel 5, and one side of the first hand wheel 5 is rotatably connected to one side of the baffle 3, and the other end of the first threaded rod 4 is fixedly connected to a gasket 6, and the surface of the gasket 6 is rotatably connected to the inner wall of the protective plate 2;

[0031] First, place the neck of the mouse on one side of the top of the base 1, and then after placing the torso of the mouse in the protective plate 2 and the base 1, turn the first hand wheel 5. The rotation of the first hand wheel 5 drives the threaded rod 4 on one side to rotate. The threaded rod 4 rotates on both sides of the protective plate 2, thereby driving the baffle 3 on the surface to move. The two groups of baffles 3 move relative to each other in the protective plate 2, thereby fixing the neck of the mouse in the protective plate 2.

[0032] Reference Figures 1 to 4As shown, a connecting groove 7 is provided on one side of the base 1, a placement groove 8 is provided on the inner wall of the base 1, a clamping groove 9 is provided on the bottom of the protective plate 2, a clamping block 10 is slidably connected to the inner wall of one side of the base 1, a spring 11 is fixedly connected to one side of the clamping block 10, and a push plate 12 is fixedly connected to the surface of the clamping block 10;

[0033] First, place the torso of the rat in the placement groove 8 in the base 1, then place the tail of the rat in the connecting groove 7, and then push the push plate 12 to move the push plate 12 to the side of the spring 11. The movement of the push plate 12 drives the block 10 on one side to move, and then rotate the protective plate 2 to the top of the base 1. After the protective plate 2 is overlapped on the top of the base 1, the block 10 is inserted into the slot 9, and then release the push plate 12. The spring 11 of the block 10 resets the block 10. After the reset of the block 10, it is inserted into one side of the inner wall of the slot 9, thereby fixing the protective plate 2. After the protective plate 2 is fixed, the torso of the rat is restricted in the protective plate 2.

[0034] Reference Figure 1 . Figure 2 , Figure 4 and Figure 5 As shown, a rubber pad 13 is fixedly connected to one side of the top of the base 1, a threaded sleeve 14 is fixedly connected to both sides of the top of the base 1, a second threaded rod 15 is threadedly connected to the inner wall of the threaded sleeve 14, a pressing plate 16 is rotatably connected to the top of the second threaded rod 15, a second hand wheel 17 is fixedly connected to the top of the second threaded rod 15, and arc plates 18 are fixedly connected to both sides of the bottom of the pressing plate 16;

[0035] After fixing the torso and neck of the rat, the second hand wheel 17 is rotated. The rotation of the second hand wheel 17 drives the second threaded rod 15 at the bottom to rotate. The threaded rod 15 rotates in the threaded sleeve 14, thereby receiving the threaded rod 15 in the threaded sleeve 14. The descent of the threaded rod 15 drives the pressure plate 16 at the top to descend. After the pressure plate 16 descends, the arc plates 18 on both sides of the bottom are driven to descend. After the pressure plate 16 and the arc plates 18 descend, the head of the rat is fixed on the top of the rubber pad 13, and the staff can observe the head of the rat through the holes opened on the surface of the pressure plate 16.

[0036] Working principle: first place the trunk of the rat in the placement slot 8 in the base 1, then place the tail of the rat in the connecting slot 7, then push the push plate 12 to move the push plate 12 to the side of the spring 11, and the movement of the push plate 12 drives the card block 10 on one side to move, and then rotate the protective plate 2 to the top of the base 1. After the protective plate 2 is overlapped on the top of the base 1, the card block 10 is inserted into the card slot 9, and then release the push plate 12. The spring 11 of the card block 10 resets, and the card block 10 is reset and is inserted into one side of the inner wall of the card slot 9, thereby fixing the protective plate 2. After the protective plate 2 is fixed, the trunk of the rat is confined in the protective plate 2, and the first hand wheel 5 is rotated.
