摘　　要：目的分析各种品牌医用防护口罩的适合性检验通过率,探讨快速根据头面尺寸匹配医用防护口罩的方法。方法选择天津市定点医院的202名医务人员作为研究对象,对A、B、C、D、E 5种品牌口罩采用气溶胶凝结核计数器进行定量适合性检验。采用二维摄影测量获取研究对象形态面长及面宽,对应颜面分栏将研究对象脸型归为#1~#10类。比较各颜面分区研究对象口罩通过率、不同品牌口罩测试通过率、不同脸型研究对象各种口罩测试通过率的差异。结果共有202名测试人员参加本研究。根据颜面分栏,其中#1类脸型占比最多〔43.6%(88/202)〕,其次为#3类脸型〔18.2%(37/202)〕,研究对象多为#1、#2、#3、#4类脸型,共176名,占87.1%。202名测试者共进行914次测试,通过次数678次,整体口罩通过率为74.18%。A、B、C 3种品牌口罩通过率明显高于D、E口罩〔87.03%(161/185)、85.57%(166/194)、82.02%(146/178)比62.98%(114/181)、51.70%(91/176),均P<0.05〕,头戴式可调节口罩通过率明显高于不可调节口罩〔79.54%(587/738)比51.70%(91/176),P<0.05〕,B品牌口罩对<#1~#5类脸型的适合因数(FF)明显高于#6~#10类脸型〔200(163,200)比132(86,200),P<0.05〕。结论通过二维摄影测量可以快速获得研究对象面部信息并匹配相应口罩,医院在配置时可根据医务人员脸型分区占比情况匹配测试通过率较高的口罩。在口罩选择中,尽量选择头戴式可调节口罩。Objective To investigate the pass rates of fit tests for various brands of medical protective masks and to explore methods for quickly matching these masks based on their head and face dimensions.Methods A total of 202 medical staff from designated hospitals in Tianjin were selected as subjects.Quantitative fit tests were conducted on 5 brands of masks(A,B,C,D,and E)using an aerosol condensation nucleus counter.Two-dimensional photographic measurement was used to obtain the face length and width of the subjects,categorizing them into face types#1 to#10.The pass rates of masks across different face zones,brands,and face types were compared.Results A total of 202 testers participated in this study.According to the guidelines,face type#1 was the most common[43.6%(88/202)],followed by face type#3[18.2%(37/202)].The majority of subjects were categorized as face types#1,#2,#3,and#4,totaling 176 subjects(87.1%).A total of 914 tests were conducted,with 678 passes,resulting in an overall mask pass rate of 74.18%.The pass rates of masks A,B,and C were significantly higher than those of masks D and E[87.03%(161/185),85.57%,(166/194),82.02%(146/178)vs.62.98%(114/181),51.70%(91/176),all P<0.05].The pass rate of adjustable head-mounted masks was significantly higher than that of non-adjustable masks[79.54%(587/738)vs.51.70%(91/176),P<0.05].The fit factor(FF)for mask B in face types#1 to#5 was significantly higher than that in face types#6 to#10[200(163,200)vs.132(86,200),P<0.05].Conclusions Two-dimensional photographic measurement can quickly obtain facial information of the subjects and match the corresponding masks.Hospitals can match masks with higher test pass rates according to the proportion of face types among medical staff.When selecting masks,preference should be given to adjustable head-mounted masks.
