医用防护口罩适合性与头面部尺寸关系的研究

Relationship between the fitness of medical protective mask and facial dimension

目的比较拱形、折叠形医用防护口罩的适合性检验通过率,探索头面部尺寸与口罩适合性检验的关系。方法选取北京市6所医院的320名医务人员,使用直角规、弯脚规、皮尺进行头面部尺寸测量,采用TSI公司8038/8048型口罩适合性测试仪,对某品牌的拱形、折叠形医用防护口罩进行定量适合性检验。结果320名受试者拱形、折叠形口罩的适合性检验通过率分别为44.38%、84.06%,差异有统计学意义(χ^(2)=103.765,P<0.001)。影响因素分析显示,形态面长对口罩适合性检验结果有影响,形态面长较长的人群佩戴拱形口罩的适合性较好,而形态面长较短的人群佩戴折叠性口罩的适合性较好。聚类分析显示,拱形口罩在较大脸型人群中的适合性高于较小脸型人群,而折叠形口罩在较小脸型人群中的适合性高于较大脸型人群。结论拱形、折叠形医用防护口罩的适合性存在差异,形态面长、佩戴者脸型是影响口罩适合性的重要因素,研究结果可为口罩生产企业提供产品设计的参考依据,为医务人员选择适合的口罩提供指导。

Objective To compare the pass rate of fitness test for arch-shaped and fold-shaped medical protective masks,and explore the relationship between facial dimension and the fitness test of mask.Methods 320 health care workers from 6 hospitals in Beijing were selected.The facial dimensions were measured by right angle gauge,bending angle gauge,and leather ruler.Quantitative fitness test of a brand of arch-shaped and fold-shaped medical protective masks was conducted by TSI 8038/8048 mask fitness test instrument.Results The pass rates of fitness tests for arch-shaped and fold-shaped masks of 320 subjects were 44.38%and 84.06%,respectively,with statistically significant differences(χ^(2)=103.765,P<0.001).Analysis of influencing factors showed that morphological facial length had an impact on the fitness test result of masks.People with long morphological facial length fit better in arch-shaped masks,and people with short morphological facial length fit better in fold-shaped masks.Cluster analysis showed that arch-shaped masks fit large face better than small face,while fold-shaped masks fit small face better than large face.Conclusion There are difference in the fitness of arch-shaped and fold-shaped medical protective masks.The morphological facial length and the shape of the user’s face are important factors influencing the fitness of masks.The results of this study can provide references to product design for mask manufacturers and guidance for health care workers in the selection of suitable masks.
