摘要
为了研究战伤喷剂杀菌效果及其影响因素,采用悬液定量杀菌试验进行了观察。结果,季铵盐活性物170mg/L喷剂分别作用5min,对金黄色葡萄球菌和大肠杆菌平均杀灭率为99.99%;用850mg/L该喷剂对白色念珠菌作用5min,平均杀灭率为99.99%。该喷剂在54℃放置14d,其杀菌效果无明显降低。受有机物和作用温度等因素对其杀菌效果影响不明显。以该喷剂原液作皮肤喷雾消毒,对自然菌平均除菌率为89.13%。结论,该战伤喷剂可有效杀灭细菌繁殖体和真菌,性能稳定。
In order to study the gemicidal efficacy of war wound spray and its influencing factors, suspension quantitative germicidal test was used for observation. Results： The spray containing quaternary ammonium salt active substance 170 mg/ L with a 5 min contact time killed 99.99% in average of Staphylococcus aureus and Escherichia coli. The spray 850 mg/ L with a 5 min contact time killed 99.99% in average of Candida albicans. The germicidal efficacy of the spray did not decrease obviously after storing at 54℃ for 14 days. Organic substance and temperature had no significant influence on its germicidal efficacy. Spraying disinfection of skin with the stock solution of this spray eliminated 89.13% in average of the natural bacteria. Conclusion ： The war wound spray can effectively kill the vegetative forms of bacteria and fungi and is stable in property.
