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...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 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 good disinfection effect, which can effectively prevent bacterial pollution in indoor air, but it is better than ordinary spray spraying, traditional Chinese medicine fumigation, and chlorine disinfection. Aerosol disinfectant is more durable in maintaining disinfection time.展开更多
