Description

Technical Field

[0001] The utility model relates to the technical field of mouse tail suspension test and a mouse tail suspension test device. Background Art

[0002] The mouse tail suspension test is a classic method that can quickly evaluate the efficacy of antidepressant drugs, excitatory drugs, and sedative drugs. The principle of this experiment is to fix the mouse's tail and hang its head downward, thus creating an inescapable oppressive environment. In this environment, the mouse will struggle to escape, but since its tail is fixed, it cannot escape and will eventually give up struggling and enter a specific depressive immobile state.

[0003] During the test, it is necessary to tie a rope to the mouse's tail and then hang the mouse up. However, as a living creature, when tying the rope to the mouse's tail, the mouse itself is likely to attempt to escape due to psychological factors such as fear, and at this time, the mouse will twist itself, making it inconvenient to tie the rope to the mouse's tail.

[0004] To solve the above problems, a mouse tail suspension test device is proposed in this application. Content of the Utility Model

On one side of the two limiting bands 503 close to the fixing plate 501, sheet-shaped air bags 506 are installed. An air pump 508 and a mobile power source 509 are installed on the fixing plate 501. The air pump 508 and the mobile power source 509 are electrically connected. A manifold 507 is installed at the connection end of the air pump 508. The two ends of the manifold 507 away from the air pump 508 are respectively communicated with the interiors of the corresponding sheet-shaped air bags 506. By stuffing the mouse between the fixing plate 501 and the limiting bands 503 and then starting the air pump 508, it makes the outside air enter the two sheet-shaped air bags 506 through the manifold 507, so that the two sheet-shaped air bags 506 expand to squeeze and fix the mouse, thus achieving the effect of fixing the mouse.

[0035] A support frame 3 is installed on the chassis 1. A rope 303 is provided on the support frame 3. One end of the rope 303 is fixed to the tail of the mouse, achieving the purpose of facilitating the fixing of the rope 303 to the tail of the mouse.

[0036] Among them, the specific model of the air pump 508 is F10-12, and the mobile power source 509 uses a mobile charging power source with the model 20000M produced by Kenuoke (KNK). The circuit connection method between the air pump 508 and the mobile power source 509 can be reasonably set according to the actual situation, and their signal transmission method is the prior art.

[0037] Refer to Figure 3 , A first jack 4 is opened on the chassis 1. The insertion rod 502 is adapted to the first jack 4. The insertion rod 502 is inserted into the first jack 4 to fix the position of the fixing plate 501, facilitating the fixing of the mouse on the fixing plate 501.

[0038] Refer to Figures 1-3 , A support piece 301 is installed on the support frame 3. A connection buckle 302 is detachably installed on the support piece 301. The rope 303 is detachably installed on the connection buckle 302. After one end of the rope 303 is fixed to the tail of the mouse, the insertion rod 502 is taken out from the first jack 4, and then the other end of the rope 303 is fixed to the connection buckle 302. Then the air pump 508 is started to pump out the air in the sheet-shaped air bag 506, so that the sheet-shaped air bag 506 no longer squeezes the mouse, and then the mouse is taken out from the fixing plate 501 to complete the operation of hanging the mouse.

[0039] Refer to Figure 2, chutes 504 are provided on both sides of the fixing plate 501. Sliders 505 are installed at both ends of the two limiting belts 503. The sliders 505 are slidably connected to the fixing plate 501 through the corresponding chutes 504. According to the size of the mouse, the sliders 505 are moved, thereby driving the two limiting belts 503 to move, and further adjusting the distance between the two limiting belts 503, achieving the purpose of facilitating the fixation of mice of different sizes.

[0040] Refer to Figures 3-5 , a light-shielding plate 2 is installed on the chassis 1. The light-shielding plate 2 is used to reduce environmental interference, maintain environmental stability, reduce the observer effect, and protect the eyes of the mice.

[0041] A fixing block 6 is installed on the light-shielding plate 2. A second jack 7 is penetrated through the fixing block 6. The insertion rod 502 is adapted to the second jack 7. When the fixing plate 501 is not in use, the insertion rod 502 is inserted into the second jack 7 to support the fixing plate 501, thereby achieving the effect of retracting the fixing plate 501 when the fixing structure 5 is not in use, which helps to avoid the loss of the fixing plate 501 and the problem that the fixing plate 501 protrudes too much when inserted into the first jack 4 and takes up space.

[0042] Refer to Figure 1 , an installation bracket 8 is installed on the chassis 1. A camera 9 is detachably installed on the installation bracket 8. The camera 9 is used to record and analyze the behavior of the mice in real time.

Then, one end of the rope 303 is fixed to the tail of the mouse, achieving the purpose of facilitating the fixation of the rope 303 to the mouse's tail. Then, the insertion rod 502 is removed from the first jack 4, and the other end 303 of the rope is fixed to the connection buckle 302. Then, the air pump 508 is started to pump out the air in the sheet-shaped air bags 506, so that the sheet-shaped air bags 506 no longer squeeze the mouse, and then the mouse is taken out from the fixing plate 501 to complete the operation of hanging the mouse.
