Technical Field

The invention relates to a continuous rotation activity experimental device for testing the attention of experimental animals. The experimental device consists of a rotatable transparent ball body capable of accommodating an experimental animal and an attractant supporting device outside the ball body, and can test the duration of attention of the experimental animal placed in the transparent ball body to a visual attractant as an index of test attention. The device has simple structure, low cost and simple and convenient operation. Belongs to the field of food safety or medicine function.

Background

For a long time, in the research of the function or pharmacology of foods and medicines, preliminary experiments using laboratory animals have been generally conducted, and a series of experimental devices have been invented. The existing contents comprise a swimming test and a rotating cage test for endurance or fatigue resistance tests, various maze tests for learning and memory ability tests, a tail suspension test for anxiety inhibition tests, an open field test for neuropsychiatric tests, a CPA condition aversion system test for drug addiction tests and a gait behavior analysis system test for motion coordination tests, and each test is provided with a corresponding experimental device. It provides an objective, visual and feasible observation mode for the development of food and medicine supplies, and is widely used for related research and development at home and abroad.

The attention test has not attracted enough attention of experiments and researchers for a long time, and one important reason is that the convenient and effective test method and experimental measures for testing the attention are not available. An alternative approach may be electroencephalographic observation, however this is costly, the observation criteria are not intuitive or it is difficult to determine if attention is present.

Disclosure of Invention

The invention aims to provide a continuous rotation activity test device for testing the attention of experimental animals. The experimental device has the advantages of simple structure, low cost and simple and convenient operation.

The purpose of the invention is realized by the following technical method:

A. the transparent ball body can rotate at low resistance, can accommodate experimental animals and has sufficient activity space of the experimental animals, and the side surface or the surface of the transparent ball body is provided with a vent hole and an experimental animal access door;

B. the transparent ball is arranged on a bracket with a movable supporting point or a supporting shaft;

C. the visual attractant supporting device is arranged on the outer surface or the outer surface of the transparent sphere at a certain distance.

The transparent sphere which can accommodate the experimental animal and has sufficient experimental animal activity space and can rotate with low resistance in the step A has the advantages that the rotation direction of the rotation with low resistance comprises a forward direction and a reverse direction, and the sufficient experimental animal activity space comprises the front and back movement and the turning without influencing the experimental animal.

The transparent sphere which can accommodate the experimental animal and has sufficient activity space of the experimental animal and can rotate with low resistance in the A comprises translucency, transparency, hole holes and barriers.

The transparent sphere which can accommodate the experimental animal and has sufficient activity space for the experimental animal and can rotate with low resistance in the A, wherein the material of the transparent sphere comprises plastics, glass and metal.

And C, arranging a visual attractant supporting device at a certain distance outside the transparent sphere, wherein the distance is 1-100 cm.

And C, arranging a visual attractant supporting device outside the transparent ball at a certain distance, wherein the attractant supporting device comprises a bracket, a tray, a suspension rope and a turntable.

And C, arranging a visual attractant supporting device at a certain distance outside the transparent ball, wherein the attractant supporting device comprises a transparent seal and a non-seal.

All parts of the invention form a complete technical scheme.
