ObjectiveTo explore the detection methods for various indicators of biosafety independent ventilation cages ( IVCs) and evaluate the performance indicators of self-developed biosafety mouse IVCs.Methods According to the detection methods of RB / T199 - 2015 and DB23 / T 2057. 1 - 2017,various performance indicators of a certain imported biosafety type IVC ( IVC1) and a self-developed biosafety type IVC ( IVC2) were tested, and their safety was determined. Results All indicators of the prototype IVC and control IVC meet the requirements of national standards, the detection results of airflow velocity,air cleanliness, falling bacteria, noise, illumination,temperature and relative humidity are relatively consistent between the two IVCs.However, compared with IVC1, IVC2 had certain differences in pressure difference, ventilation frequency, and airtightness indicators. Conclusion The detection method has excellent operability and can be used for on-site inspection of biosafety mouse IVC. The self-developed biosafety mouse IVC has excellent performance, safety and reliability, and can be used for thebreeding of highly pathogenic animals in high-level biosafety laboratories.
