Description

TECHNICAL FIELD

[0001] The utility model relates to animal restraint device related technical field, especially a kind of restraint device of adult zebra fish depression model. BACKGROUND

[0002] In the field of zoology research, it is often necessary to construct zebra fish models (such as depression models, anxiety models) involving restraint devices. Currently, the commonly used method is to place experimental zebra fish into a microcentrifuge tube with a tube diameter of 16.8 x 100 mm and a capacity of 2 mL for restraint. The centrifuge tube cap is closed, and the two ends are slightly open to allow the water inside the tube to circulate freely. The zebra fish used to construct the model are about 6-9 months old and about 3-5 cm long. The centrifuge tube used is larger in diameter than the body axis of the zebra fish. The centrifuge tube containing the zebra fish is clamped onto a vertical tube stand and placed in a water tank. However, this method has the following disadvantages: the process of loading the zebra fish into the centrifuge tube is difficult and time-consuming, and may cause certain external injuries to the zebra fish; the zebra fish needs to be restrained multiple times during the experiment, which may cause the death of the zebra fish; the top opening of the centrifuge tube is sharp, and larger zebra fish may be injured on the nose, posing a risk of infection and interfering with the experimental results; the microcentrifuge tube is not suitable for larger or smaller zebra fish, and the restraint space cannot be adjusted flexibly; there is visual contact between each centrifuge tube containing zebra fish, which is not suitable for more experimental requirements.

[0009] Further, the cover plate is provided with a small water outlet hole, and each restraint cell is provided with a small water outlet hole at the upper portion, and the water exchange in the river is realized by the large water outlet hole and the small water outlet hole on the cover plate.

[0010] Further, the limiting cell is provided with a pullable taking and placing strip, and the taking and placing strip is fixed in the inside of the limiting cell. The experimenter can conveniently drive the taking and placing limiting cell by moving the taking and placing strip.

[0011] Further, the limiting cell is provided with different thicknesses in the range of 2mm-10mm, and different thicknesses of the limiting cell can cause different internal spaces to adapt to zebrafish of different sizes.

[0012] Further, the color of the limiting cell is provided with three types of yellow, black and transparent, and the experimental zebrafish likes or dislikes the three colors, and the mood variable of the experimental zebrafish can be controlled at the same time.

[0013] Further, the box body, the restraint cell, the limiting cell, the cover plate and the taking and placing strip are made of acrylic, and the physical and chemical properties of the acrylic material are stable at normal temperature, and the consumables are easy to obtain and manufacture.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The restraint device for adult zebrafish depression of the utility model can adjust the thickness of the limiting cell, thereby adjusting the restraint space of the experimental zebrafish, and adapting to experimental zebrafish of different sizes.

[0016] 2. The utility model can control the mood variable of the experimental zebrafish through the color of the limiting cell.

[0017] 3. The utility model can simultaneously experiment and observe multiple experimental bodies under the condition that the water flow variable is the same, thereby saving the time cost of the experiment. BRIEF DESCRIPTION OF DRAWINGS
