摘　　要：目的研究新材质手术衣的阻菌效果。方法采用半定量和定性两种试验方法对3种手术衣的关键部位(胸口和前臂)布料进行微生物阻菌率的检测,3种样本分别为:样本A(复合材料,未使用);样本B(复合材料,洗涤100次后);样本C(单层材料,未使用)。结果半定量试验中,3种样品的平均阻菌率分别为75.47%、70.78%、73.73%。定性试验中,3种样品在湿性条件下能有效阻隔金黄色葡萄球菌透过,在干燥条件下能有效阻隔枯草杆菌黑色变种芽孢透过。结论半定量试验中,3种样品均有阻菌作用,平均阻菌率均>70%;定性试验中,干、湿性条件下3种样品的阻菌效果均符合要求。Objective To study bacteria-blocking effect of surgical gowns with new material.Methods Semi-quantitative and qualitative testing methods were used to detect bacteria-blocking rates of key sites of surgical gowns（chest and forearm）, the detected samples included sample A （composite material, unused）, sample B （composite material, after washing 100 times）, and sample C （monolayer material, unused）.Results In semi-quantitative testing,the average bacteria-blocking rates of three samples were 75.47%, 70.78%, and 73.73% respectively.In qualitative testing,three samples could effectively block the penetration of Staphylococcus aureus under wet condition and Bacillus subtilis var.niger spores under dry condition.Conclusion In semi-quantitative testing, all three kinds of samples had bacteria-blocking effect, and the average bacteria-blocking rate was〉 70%;in qualitative testing, three samples all meet requirements of bacteria-blocking effect under wet and dry condition.
