Description

Technical Field

[0001] The utility model relates to the technical field of experimental restraint devices, in particular to a restraint device for experimental mouse stress experiments. Background Art

[0002] In biomedical research, laboratory mice are widely used as model organisms in stress experiments to study the physiological, psychological, and behavioral effects of stress. These studies are crucial for understanding human disease, drug response, and mental health. To ensure experimental reliability and consistency, restraint and control of laboratory mice are crucial in stress experiments.

[0003] However, in practice, traditional methods of restraining lab mice often present several issues. Many existing restraint devices are fixed, making it difficult to flexibly adjust the strength and method of restraint according to experimental needs. This single restraint method can cause excessive stress in lab mice during experiments, affecting the accuracy of experimental results. Furthermore, after multiple experiments, impurities such as hair and debris can accumulate within the restraint device. Cleaning traditional devices is often cumbersome and time-consuming, impacting both experimental preparation efficiency and environmental hygiene.

[0004] Therefore, it is particularly important to develop an efficient, flexible and safe restraint device for stress experiments on experimental mice. Utility Model Content
