Changes of main performance indicators of simulated reused surgical masks after cleaning and disinfection

摘要:

目的 医用外科口罩模拟复用清洗和消毒后主要性能指标变化。方法 以颗粒过滤效率（PFE）、细菌过滤效率（BFE）作为医用外科口罩的关键性能指标，对不同佩戴时间、不同干燥方式、不同洗消方式等试验条件进行验证。结果 试验后的医用外科口罩关键性能指标能够符合标准要求。结论 医用外科口罩采用清水洗涤、56℃热水浸泡和100℃沸水浸泡处理后主要性能指标未见明显下降。

Abstract:

Objective To evaluate changes of main performance indicators of surgical masks after simulated reuse cleaning and disinfection. Methods Particle filtration efficiency (PFE) and bacterial filtration efficiency (BFE) were used as the key performance indicators of surgical masks, experimental conditions such as different wearing time, different drying methods as well as different washing methods were verified. Results The key performance indicators of surgical mask after experiment met the standard requirements. Conclusion After water washing, 56℃ hot water immersion and 100℃ boiling water immersion, the main performance indicators of surgical masks don't decrease significantly.
