空气清菌片与紫外线灯消毒效果的比较

Comparative Study on Effectiveness of Air Disifection Methods Between Anti-bacteria Tablet and Ultraviolet Radiation Lamp

目的探讨2种空气消毒方法在临床应用中各自的优势及消毒效果与实用性。方法分别在相同条件下采样 ,比较消毒前后2种方法空气消毒效果。结果在消毒时间上清菌片持续杀菌效果优于紫外线灯 ,通过6次空气自然菌消毒前后采样结果表明 ,清菌片消毒后空气自然菌消毒率为87.04 % ;紫外线灯消毒后空气自然菌消毒率为81.70%。结论清菌片消毒效果稳定 ,持久且操作方便 ,不受条件限制及环境影响 。

Objective To explore the advantages, disinfective effectiveness and practicality of two air disinfection methods in clinical application. Methods The disinfective effects were compared before and after disinfection under the same sampling conditions. Results The effective duration of disinfection by anti_bacteria tablet was longer than that by ultraviolet radiation lamp. Disinfective effects of 6_time sampling of air samples before and after disinfection showed that the bactericidal rates were 87.04% for anti_bacteria tablet and 81.7% for ultraviolet radiation lamp. Conclusion Anti_bacteria tablet presented stable and permanent disinfective effectiveness, and was easy to operate. Application of this method was not restricted by conditions and its effectiveness was not effected by environment. This method was suitable for air disinfection in hospitals and public places.
