医用口罩的技术标准对比研究及前景展望

针对我国在抗击新冠肺炎疫情中对医用口罩需求的现状，系统综述了医用口罩的技术标准、制备工艺、防护效果及发展概况，分析和比较了各类医用口罩在防护性能上的优势，并对其适用范围给出了合理建议。通过对比各类医用口罩技术标准，发现经过驻极处理的GB 19083—2010医用防护口罩过滤效率最高，不低于95%，适用于传染科或病毒科医务人员和相关工作人员佩戴防护，但存在透气性差、无抗菌性等方面的不足。经分析，高抗菌性、高抗病毒性、佩戴舒适性的新型医用口罩是未来的重要发展方向。

Technical standards and prospects of medical masks

Considering the current situation fighting against the COVID-19 and the demand for medical masks in China, the technical standards, preparation technology, protective effectiveness and development of medical masks were summarized in this paper. The advantages of various medical masks in protective performance were also analyzed and compared，then the reasonable suggestions on the application scope of masks were proposed. Results show that GB 19083—2010 medical protective masks with electret treatment have the highest filtering efficiency compared to other types of medical masks, which is not less than 95%. It is suitable for the protection of medical personnel and related staff in the department of infectious diseases or virus. However, there are still some problems such as poor air permeability and no antibacterial property. In the analysis, the new type of medical masks with high antibacterial, high resistance to virus and comfortable wearing are the most desirable properties in the near future.
