摘　　要：目的 检验医务人员佩戴的医用防护口罩的适合性,探索影响定性适合性检验结果的影响因素。方法 选择在某新冠肺炎定点医院参与疫情防控工作的221名医护、行政后勤人员作为研究对象,采用美国职业安全健康管理局(OSHA)认可的苦味剂气溶胶法(3M^(TM)FT-30)进行定性适合性检验。结果 敏感性测试共201人通过,其中1级敏感度169人(84.1%)、2级敏感度30人(14.9%)、3级敏感度2人(1.0%),适合性检验201人中一次性通过188人,第二次测试通过5人,其中有8人测试不通过,通过率96.02%。影响因素分析显示,BMI指数对口罩的适合性检验结果有影响(P<0.05),而性别、年龄、是否佩戴眼镜、是否有双下巴、脸型大小、是否佩戴护目镜、形态面长、面宽、鼻宽及两耳屏点颌下弧长不是影响定性适合性检验结果的因素。结论 测试所用折叠式医用防护口罩定性适合性检验通过率较高,BMI指数是其影响因素之一;一线医务人员应通过定性适合性检验来验证医用防护口罩的密闭性,选择适合自身脸型的医用防护口罩。OBJECTIVE To test the suitability of medical protective masks worn by medical staff and explore the factors that affect the results of qualitative suitability tests. METHODS A total of 221 medical and administrative staff who participated in the prevention and control of the COVID-19 epidemic in a designated hospital were recruited as the study objects, and the qualitative suitability testing was carried out by using bittering agent aerosol method(3M^(TM)FT-30) approved by the Occupational Safety and Health Administration(OSHA). RESULTS Totally 201 were qualified for the sensitivity test, including 169(84.1%) objects with level 1 sensitivity, 30(14.9%) objects with level 2 sensitivity, 2(1.0%) objects with level 3 sensitivity. Among the 201 objects, 188 passed the first test, 5 objects passed the second test, and 8 objects did not pass the test, with the pass rate 96.02%. The analysis of influencing factors showed that the BMI index affected the result of the suitability test(P<0.05), however, the genders, ages, wearing glasses, double chin, size of face, wearing goggles, shape of face length, width of nose and submandibular arc length of the two tragus points were not the influencing factors for the result of qualitative suitability test. CONCLUSION This foldable medical protective mask has a high pass rate in the qualitative suitability test, and the BMI is one of the influencing factors;first-line medical staff can verify the airtightness of the medical protective mask through the qualitative suitability test so as to choose the appropriate medical protective masks.
