Description

Technical Field

[0001] This utility model belongs to the field of medical experimental technology, specifically relating to a rat observation device that is easy to assemble and disassemble. Background Technology

[0002] In animal experimental research, rat behavioral observation devices are important experimental tools in neuroscience, pharmacology, and other fields. Currently, the observation of penile erectile function in rats needs to be conducted in a dark room. After drug injection, rats often defecate and urinate during the observation period, which is not conducive to subsequent cleaning. Traditional rat observation boxes usually adopt a fixed box structure or a simple upper and lower split design, requiring researchers to frequently open the box lid for intervention or observation, which can easily interfere with the animal's natural behavioral state.

[0003] Chinese utility model patent CN210071798U discloses a rat observation box for an apomorphine screening test, comprising a cylindrical box body, which includes an inner box body and an outer box body made of non-transparent material. The inner box body is suspended in the outer box body by several support rods set at its upper and lower parts. Several ventilation holes are evenly arranged on the top of the inner and outer boxes respectively. A supplementary light is set on the top of the inner box body, and the bottom of the inner box body is a grid base plate. Several infrared cameras are arranged circumferentially on the bottom of the outer box body, and a ventilation fan is installed on the lower side wall of the outer box body. Double-layer movable doors for rats to enter and exit are set at corresponding positions on the side walls of the inner and outer boxes. However, the observation box is a single piece for both the inner and outer boxes, which is inconvenient to disassemble and make subsequent disinfection and cleaning difficult. Utility Model Content
