局部空气净化装置对手术室空气的消毒效果

目的观察空气消毒机对医院手术室空气消毒效果,以评价其实际应用效果。方法采用平板沉降采样和细菌培养方法,评价该多因子组合空气净化装置对手术室空气中自然菌净化效果,并与紫外线灯照射消毒作平行比较。结果启动YKX/Y型空气消毒机和紫外线灯作用30 min,5 min后采样,手术室空气中细菌总数<200cfu/m3,随着时间的延长,空气中菌数逐渐增加,15 min后细菌总数逐渐增加到200 cfu/m3以上。在手术室有6人工作的情况下,空气消毒机持续运行,可使空气细菌继续保持在<200 cfu/m3。结论试验用空气消毒机可以在手术期间持续消毒,可以维持手术室内空气中细菌总数<200 cfu/m3。

AIR DISINFECTION EFFECT IN THE OPERATING ROOM OF HOSPITAL BY USING THE LOCAL AIR PURIFICATION DEVICE

Objective To observe the air disinfection effect in the operating room of hospital by using the local air purification device and evaluate the practical application effect of the device.Methods By using the methods of tablet settlement sampling and bacterial culture,to evaluate and compare the effect of air purification in the operating room by the air purification device and ultraviolet light irradiation.Results 5 mins later after using the air disinfection device of YKX / Y-type and the ultraviolet ray lamp for 30 mins,the total number of bacteria in the air of operating room was less than 200 cfu/m3.As the time prolonged to 15 min,the bacteria number increased to more than 200 cfu/m3.Under the condition of six persons working and the air disinfection device running continuously in the operating room,the bacteria in the air maintained less than 200 cfu/m3.Conclusion The air purification device can continue disinfection during surgical operation and the number of bacteria can maintain less than 200 cfu/m3.
