复方桂枝电热挥散剂对空气消毒效果的观察

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。

OBSERVATION ON AIR DISINFECTION EFFICACY OF COMPOUND EXTRACT OF RAMULUS CINNAMOMI VAPORIZED BY ELIECTRIC VAPORIZER

Objective To observe the air disinfection efficacy of compound extracts of Ramulus Cinnamomi vaporized by electric vaporizer on inpatient wards.Methods Flat slab exposure method for sampling and bacteria culture method were used to monitor the air disinfection efficacy of vaporized compound extract of Ramulus Cinnamomi.Results Several pieces of filter paper soaked with volatile oil of Ramulus Cinnamoni which was heated by electric heating device for fumigation for 30 minutes in a 48 m3 airtight room could reduce the average count of natural bacteria in the air from 1252 cfu/m3 to 471 cfu/m3.The efficacy was similar to that of ultraviolet irradiation for 30 min.There was no difference whether the room was closed or not.After heating and fumigating by electric heating device for 30 min,the vaporized R.Cinnamomi was volatized by above 80%,after heating for 120 min it was volatized by 100%.Conclusion The vaporized compound extract of Ramulus Cinnamomi fumigation has good efficacy in killing the natural bacteria in indoor air.
