摘要
目的:将超细氯化钠粉喷射入空气中形成一定浓度的盐气溶胶,观察该气溶胶对空气的消毒效果。方法:利用反溶剂法将岩盐制备成超细氯化钠,采用平板自然沉降法采集消毒前和消毒后空气中菌落,检测不同时间段采集的菌落数并进行鉴定,评价氯化钠气溶胶对空气的消毒作用。结果:氯化钠气溶胶对空气中菌落总数、金黄色葡萄球菌、大肠埃希菌、铜绿假单胞菌、肺炎克雷伯菌、芽孢具有明显的杀灭作用。结论:超细氯化钠粉喷射入空气中形成的气溶胶消毒作用明显,可考虑作为野战手术室空气消毒手段的替代品。
Objective： The ultra-fine sodium chloride powder was sprayed to the air and formed a certain concentration of salt aerosol,to study the aerosol on air disinfection. Methods： The ultra-fine sodium chloride was prepared by the way of anti-solvent,and natural sedimentation method was used to collect colonies before and after disinfection. The number of colonies at different sedimentation time points were counted and identified. The disinfection effects of sodium chloride aerosol were evaluated. Results：Sodium chloride aerosol has significant bactericidal effects not only on the total number of bacterial colonies,but also specially on Staphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa,Klebsiella pneumoniae and spores. Conclusion： The bactericidal effects of the ultra-fine sodium chloride aerosol are significant and can be considered as a substitute for traditional air disinfection methods at operating rooms of the field hospital.
