目的观察复方桂枝电热挥散剂对医院病房空气消毒的效果。方法采用平板沉降法采样和培养方法,在病房内对复方桂枝电热挥散剂消毒空气的效果进行监测。结果在密闭的48 m3病房内用电子加热器加热若干张浸透复方桂枝挥发油的滤纸片,散发熏蒸30 min,可使消毒前空气中平均自然菌数由1252 cfu/m3下降到消毒后471cfu/m3。紫外线照射消毒30 min,消毒前后菌数与复方桂枝挥散液消毒组基本一致;房间密闭与否无明显差异。在专用电子加热器上加热30 min该挥散剂挥发掉80%以上,加热至120 min挥发率为100%。结论复方桂枝挥散剂用电子加热器加热熏蒸,对室内空气中自然菌具有一定的除菌作用。
Objective To observe the effect of compound Guizhi electric volatile dispersant on air disinfection in hospital wards. Methods The method of flat sedimentation sampling and culture was used to monitor the effect of compound Guizhi Electro-Volatile Air disinfectant in the ward. Results In a confined 48 m3 ward, several sheets of filter paper impregnated with the volatile oil of Radix et Rhizoma Corydalis were heated with an electronic heater for 30 min. The mean natural bacterial count in air before disinfection decreased from 1252 cfu / m3 to 471 cfu / m3 after disinfection. m3. UV irradiation disinfection 30 min, the number of bacteria before and after disinfection compound Guizhi volatile liquid disinfection group basically the same; the room was closed or not no significant difference. In a dedicated electronic heater heated 30 minutes volatilize volatiles off more than 80%, heated to 120 min volatilization rate of 100%. Conclusion The compound Guizhi volatile powder is heated and fumigated by electronic heater, which has a certain bactericidal effect on the natural bacteria in indoor air.
