[0002] Germ-free mice are commonly used in bioequivalence experiments, and the efficacy of drugs is evaluated by preparing animal models. With the rapid development of scientific research, the demand for germ-free mice has gradually increased. Germ-free mice are raised in a sterile environment after birth. During the breeding process, feed and water are disinfected to ensure that there are no parasites and microorganisms inside and outside the body of germ-free mice.
[0003] Sterile mouse breeding boxes are commonly used breeding equipment, which need to be disinfected regularly. Currently, the commonly used disinfection method is ultraviolet disinfection. During ultraviolet disinfection, in order to ensure the safety of the mice, the mice are first moved out of the breeding box, and then moved back into the breeding box after disinfection. This method of moving mice in and out, if not operated properly, will cause sterile mice to be contaminated. In other words, this method has certain pollution risks.
