Description

Technical Field

[0001] The utility model relates to a device for reading the running distance of a running wheel of laboratory mice and rats, and belongs to the technical field of medical experimental equipment. Background Art

[0002] Studying the locomotor behavior of animals has important scientific and applied significance. It can help understand the basic biological functions of laboratory mice and rats, such as locomotor ability, biological rhythm, and how they are affected by external experimental interventions, which is crucial for revealing human health problems. In addition, locomotor behavior can be used as an indicator to evaluate the anxiety, depression, and cognitive function of laboratory mice and rats. Through different experiments (such as open field test and maze experiment), it can provide information about the mental state. In drug development and treatment evaluation, studying the locomotor behavior of animals can help evaluate the effects of drugs and treatments, while ensuring the reliability of experimental design and the validity of data.

[0003] The existing running wheel structure can effectively and real - time observe the experimental mice during their movement. The existing running wheels, such as a special electric running wheel for experimental mice with a timer disclosed in Chinese patent document CN219108451U, are basically of an integrated design. However, the sizes of experimental mice vary. If different - sized experimental mice need to be matched, different - sized wheel frames need to be replaced. When replacing the wheel frame, the convenience of replacement and the accuracy of counting need to be considered. Obviously, the existing integrated - design running wheels cannot achieve this. Therefore, the present utility model is proposed. Summary of the Invention
