新型冠状病毒肺炎疫情期间非医用口罩(N95/KN95)在临床上的应急使用方法

Study on the Clinical Emergency Use of Non-medical N95/KN95 Masks During the Pandemic of COVID-19

武汉新型冠状病毒肺炎疫情发生以来,武汉地区医用防护口罩曾出现供不应求的状况,其中大量非医用类N95/KN95口罩以社会捐助的形式进入武汉收治新型冠状病毒肺炎患者的专科医院。文章通过对这类口罩有关标准和产品说明书的解读,分析这些口罩与医用防护口罩的各项性能异同点,设计可行的实验方法进行验证,通过验证的口罩将在医用防护口罩紧缺时作为应急使用。

There had been a shortage of medical protective masks in Wuhan Since the outbreak of COVID-19,while a large number of non-medical N95/KN95 masks were donated to the designated hospital of treating COVID-19 patients by all the walks of society.The simple performance verification test was designed to verify the possibilities of using those masks at clinical emergency by interpreting the relevant standards and product instructions of those masks and analyzing the similarities and differences between those masks and medical protective masks so that the verified non-medical masks could be used at clinical emergency when the medical protective masks were in short supply.
