Mouse cage for mouse sweet water preference experiment

Abstract

The embodiment of the invention discloses a mouse cage for a mouse sweet water preference experiment. The mouse cage comprises a cage cover and a box body, and also comprises a rotating disc which isrotatably disposed on the cage cover through a bearing, and the bearing is fixed on the cage cover; the bearing is connected with a driving device and a timer, and the driving device drives the bearing to rotate by a preset angle according to the timing period of the timer; at least two automatic ball drinking bottles are installed on the rotating disc at intervals, liquid with different sweetnessis contained in each automatic ball drinking bottle, a ball is arranged in a suction nozzle of each automatic ball drinking bottle, a weighing device is arranged on a bottle body of each automatic ball drinking bottle, and each weighing device is provided with a display screen; the display screens display the weight of liquid in the drinking bottles; and when the driving device drives the bearingto rotate by the preset angle according to the timing period of the timer, the at least two automatic ball drinking bottles on the rotating disc also rotate by the preset angle along with the bearing. The experimental data for testing the sweet water preference of rats or mice can be more convenient and accurate.

Description

technical field [0001] The present application relates to the technical field of animal science experiments and research devices, in particular to a rat cage used for rat sugar water preference experiments. Background technique [0002] The sugar water preference test is an experiment used to test the degree of preference of rats or mice to sugar water. It is a test indicator reflecting anhedonia in rats or mice. Anhedonia refers to the lack of interest in rewards such as food and sex. , as the core indicator for evaluating affective disorder disease models such as depression rat or mouse models, the sugar water preference experiment has an irreplaceable important position. In the experiment, there is no experimental device specially used for sugar water preference testing. Usually, a common mouse cage is used to add a water bottle to the other side for testing. Put the positioning hole of the water bottle, which will cause the water bottle to shake up and down during the t...

Problems solved by technology

In the experiment, there is no experimental device specially used for sugar water preference testing. Usually, a common mouse cage is used to add a water bottle on the other side for testing. Put the positioning hole of the water bottle, which will cause the water bottle to shake up and down during the test and cause liquid leakage, and it will also cause liquid leakage when the experimental mice drink water. In addition, the position of the water bottle needs to be exchanged during the test, and it is placed and removed when calculating the mass. The water bottle process will also cause liquid leakage, which will lead to a large error in the sugar water preference experiment and affect the evaluation of the behavioral experiment.
