The rat restraint device designed by the utility model solves the problems of inaccurate test results and low efficiency caused by irregular experimental equipment when making models of rat depression and chronic stress.

Description

A rat restraint device

technical field

The utility model belongs to biological experiment equipment, in particular to a rat restraint device.

Background technique

A series of CUMS (Chronic Unpredictable Minor Stimulation) stimulation or CUS stimulation (Chronic Unpredictable Stimulation) is usually used to make models of depression and chronic stress in rats. One form of stimulation commonly used during stimulation involves restraining the rat. According to the needs of the experiment, the rats need to be placed in a relatively closed environment to limit their activities. At present, in scientific research experiments, the common method is to stuff rats into a homemade container or drink bottle. This operation is not standardized and can easily lead to experimental errors: on the one hand, the self-made containers are of different sizes and are difficult to meet the requirements of the experiment, resulting in inaccurate experimental results; It is time-consuming to carry out the next operation.

Utility model content

In order to solve the problems of inaccurate test results and low efficiency caused by irregular experimental equipment when making models of rat depression and chronic stress, the utility model designs a rat restraint device.

The technical scheme of the utility model to solve the above-mentioned problems is: a rat restraint device, including a restraint frame and a restraint tube, the restraint frame includes a base and brackets fixed on both sides of the base, cross bars are connected between the brackets, and the restraint tube is fixed on the horizontal On the rod, the restraint tube includes two inner and outer sleeves nested with each other. One end of the inner sleeve is covered with a cover, and the other end is embedded in the outer sleeve with one end closed. The advantage is that the device mainly includes two parts: a restraint frame and a restraint cylinder, and a plurality of restraint cylinders can be fixed on the restraint frame at most. When in use, open the cover of the restraint tube, place the captured rat in the restraint tube, adjust the positions of the inner and outer sleeves of the restraint tube according to the size of the rat, and then cover the cover of the restraint tube.

In the rat restraint device, a sliding groove perpendicular to the base is formed on the surface of the bracket, and is connected to the cross bar through bolts. Its advantage is: can adjust the height of crossbar by bolt.

In the rat restraint device, a plurality of restraint tubes are arranged on the cross bar, and the cross bar and the restraint tubes are screwed and fixed. Its advantage is: multiple rats can be restrained at the same time each time, and the experimental efficiency can be increased. Each restraint cylinder is fixed on the fixed frame by the screw at the bottom, and the restraint cylinder can be easily removed and installed.

In the rat restraint device, the inner sleeve and the outer sleeve are integrally formed of plexiglass. Its advantages are: plexiglass has excellent light transmission performance, convenient for observation, and has high mechanical strength, certain heat and cold resistance, corrosion resistance, and good insulation performance.

In the rat restraint device, screw holes are opened on the surface of the outer sleeve, and the relative positions of the inner and outer sleeves are controlled by screws. The advantage is that the positions of the inner and outer sleeves can be adjusted, and then fixed by screws.

For the rat restraint device, rubber foot pads are fixed under the base. Its advantage is: when keeping the test, the stability of the base and the support.

The device is simple to operate, and can be simple, convenient and standardized when used for rat restraint stimulation experiments.

Detailed ways

Below in conjunction with accompanying drawing, the structure of the present utility model is explained in detail, as Fig. 1 is the front view of structure of the present utility model; A kind of rat restraint device, comprises restraining frame 1 and restraining tube 2, and restraining frame comprises base 1-1 and fixing The brackets 1-2 on both sides of the base are connected to the crossbar 3 between the brackets, and the restraint cylinder is fixed on the crossbar. The restraint cylinder includes two inner sleeves 2-1 and outer sleeves 2-2 nested in each other. One end of the sleeve is covered with a sleeve cover 4, as shown in Figure 3, which is a schematic structural diagram of the restraint sleeve of the present invention; the other end is embedded in the outer sleeve with one end closed. The surface of the support has a sliding groove 5 perpendicular to the base, as shown in Figure 2, which is a side view of the structure of the utility model; and is connected with the cross bar by bolts 6. A plurality of restraining tubes are arranged on the cross bar, and the cross bar and the restraining tubes are screwed and fixed. The inner and outer sleeves are made of plexiglass as a whole. There are screw holes on the surface of the outer sleeve, and the relative positions of the inner and outer sleeves are controlled by screws 7 . Fixed rubber pad 8 below the base.

The bondage frame is made of steel, and the bondage tube is made of transparent plexiglass; 4 bondage tubes can be fixed on each bondage frame; there are four rubber feet under the base fixed on the base by screws. The bracket is welded on the base. Each restraint tube is fixed on the cross bar through the screw at the bottom, and the restraint tube can be removed, and the captured rat is placed in the inner sleeve of the restraint tube. After adjusting the positions of the inner sleeve and the outer sleeve of the restraint tube, Cover the lid of the restraint tube; adjust the height of the cross bar, and then install the restraint tube on the restraint frame.

The above-mentioned technical solutions only embody the preferred technical solutions of the technical solutions of the utility model, and some changes that may be made by those skilled in the art to some parts thereof all reflect the principles of the utility model and belong to the protection scope of the utility model.
