【摘要】：测量两种KN95颗粒物防护口罩的适合性和人体头面部尺寸,分析影响口罩适合性的人体尺寸因素。选择80名受试对象,使用弯角规和直角规进行头面部尺寸测量。受试者分别佩戴3M8210、3M 8210v颗粒物防护口罩,使用TSI 8038进行定量适合性检验。两种口罩的适合性检验通过率无差异(P0.05),通过率无性别差异(P0.05)。男性鼻宽对3M 8210的适合性有影响(P0.05),女性面宽和两耳屏点间颌下弧长对3M 8210v的适合性有影响(P0.05)。面宽和鼻宽可作为初步选择颗粒物防护口罩的参考指标,但仍需经过定量适合性检验。
[Abstract]:The fitness of two kinds of KN95 particulate protective masks and the size of human head and face were measured, and the factors affecting the fitness of the masks were analyzed. 80 subjects were selected. The head and face dimensions were measured with corner gauge and right angle gauge. The subjects were respectively wearing 3M8210v particulate protective mask, 3M8210v, 3M8210v, 3M8210v and 3M8210v respectively. TSI 8038 was used for quantitative fitness test. There was no difference in the pass rate of the two masks. There was no difference in the pass rate. The male nasal width had an effect on the suitability of 3M 8210. The female face width and the length of the submandibular arc between the two ear points had a positive effect on the fitness of the 3M 8210. The suitability of 3M8210v has an effect on P0.05.The face width and nose width can be used as a reference index for the primary selection of particulate protective masks. However, it still needs to pass the quantitative suitability test.
