一种中药复方提取液空气气溶胶消毒剂的消毒效果
Disinfection Effect of an Air Aerosol Disinfectant Extracted from a Traditional Chinese Medicine Compound

目的：观察中药复方提取液空气气溶胶消毒剂的消毒效果。方法：借助气溶胶喷雾机将中药复方提取液呈气溶胶状喷洒于室内空气中，同时同普通喷雾器喷撒、中药熏蒸作对照，以通风法为空白对照、紫外线照射、氯剂消毒为阳性对照组对照，分别于消毒前、消毒后30 min、1 h、2 h、4 h各时间段采用平板空气暴露法取样，进行细菌培养，观察各种消毒方法对室内空气消毒的效果及维持时间。结果：各组消毒后30 min、1 h、2 h、4 h空气菌落数均有明显下降，同对照组比较有明显差异(P < 0.05)。消毒后30 min气溶胶喷雾组与紫外线对照组消毒效果相当，但是同其他组比较有显著差异(P < 0.05)；消毒后1 h紫外线对照组菌落低于气溶胶喷雾组，效果优于气溶胶喷雾组；但是随着消毒结束时间的不断延长，各组空气菌落数不断增多，但在同一时间点上消毒后2 h、4 h空气菌落数，气溶胶喷雾组消毒的菌落数增加程度显著低于各对照组，差异具有统计学意义(P < 0.05)。结论：复方提取液空气气溶胶消毒剂具有和紫外线消毒相同的消毒效果，两组均具有良好的消毒效果，能有效防止室内空气中细菌污染，但优于普通喷雾器喷撒、中药熏蒸、氯剂消毒，在维持消毒时间上空气气溶胶消毒剂更持久。
Objective: Observe the disinfection effect of air aerosol disinfectant extracted from traditional Chinese medicine compound. Methods: With the help of aerosol spray machine, the extract of traditional Chinese medicine compound was sprayed into the indoor air in the form of aerosol gel. At the same time, it was compared with ordinary spray spraying and traditional Chinese medicine fumigation. With ventilation method as the blank control, ultraviolet radiation, and chlorine disinfection as the positive control group, the plate air exposure method was used to sample before disinfection, 30 min, 1 h, 2 h, and 4 h after disinfection, respectively, for bacterial culture, Observe the effectiveness and maintenance time of various disinfection methods for indoor air disinfection. Result: The results showed that the air bacterial count in each group decreased significantly at 30 minutes, 1 hour, 2 hours, and 4 hours after disinfection, and there was a significant difference compared to the control group (P < 0.05). The disinfection effect of aerosol spray group 30 minutes after disinfection was similar to that of ultraviolet control group, but there was significant difference compared with other groups (P < 0.05); One hour after disinfection, the colony of ultraviolet control group was lower than that of aerosol spray group, and the effect was better than that of aerosol spray group; However, with the continuous extension of the end time of disinfection, the number of air colonies in each group continued to increase, but at the same time point, the number of air colonies in the aerosol spray group was significantly lower than that in the control groups at 2 h and 4 h after disinfection, with a statistically significant difference (P < 0.05). Conclusion: The compound extract aerosol disinfectant has the same disinfection effect as ultraviolet disinfection. Both groups have
