适用于高级别生物安全实验室的正压生物防护服性能测试分析

Performance test of positive pressure bio-protective suits for high-level biosafety laboratories

通过典型操作并结合人员主观感受对国产、进口品牌的正压生物防护服的使用性能和使用体验进行了评估。在高级别生物安全实验室中模拟工作人员工作环境,测试了防护服内部压差、气密性、噪声值和供气流量。结果表明,国产和进口正压生物防护服在产品使用性能和使用体验方面无明显差异,均能达到操作人员作业要求,可用于高级别生物安全实验室的人员防护,但均有不同程度的听觉障碍。

Evaluates the practical performance and user experience of the domestic and imported positive pressure bio-protective suits through the typical operation combining with the subjective feeling of the staff. Tests the pressure difference inside the suits, air tightness, noise level and quantity of air supply in the simulated working environment of a high-level biosafety laboratory. The results indicate that the domestic and imported positive pressure bio-protective suits have no significant differences in practical performance and user experience. Both the suits can meet the operation requirements and can be used for the staff protection of high-level biosafety laboratories, but have hearing obstacles in different degrees.
