两种方法清洗消毒简易呼吸器的效果观察

Effects of two methods of cleaning and disinfection of simple respirators

目的探讨两种消毒方法用于简易呼吸器的消毒效果,以便选择最佳的消毒方法。方法选择160个污染程度一致的简易呼吸器,随机分为两组,每组各80个,分别采用手工清洗消毒法和机械清洗消毒法对简易呼吸器进行清洗消毒。比较清洗消毒后气囊球体外表面、内腔面、接口内消毒的合格率。结果机械清洗消毒简易呼吸器各个部位合格率均为100.00%,手工清洗消毒合格率外表面100.00%、内腔面91.25%、接口内93.75%,两种方法清洗消毒后简易呼吸器外表面、接口内合格率比较,均P>0.05,差异无统计学意义;内腔面合格率比较,P<0.05,差异具有统计学意义。结论简易呼吸器机械清洗消毒法优于手工清洗消毒法。

Objective To study the effects of two disinfection methods for simple respirators in order to select the better sterilization method for the disinfection of simple respirators. Methods One hundred and sixty simple respirators contaminated at the same degree were randomly divided into the manual group and the mechanical group equally . The former took the manual cleaning and disinfection and the latter the mechanical cleaning and disinfection for the disinfection and cleaning of simple respirators. The two groups were compared with regard to the qualified rate of disinfection at the outer and inner surface and the interface of the ball cavity after disinfection cleaning. Results The qualified rates of the mechanical cleaning and disinfection at various parts of the simple respirators were 100%.The qualified rate of manual cleaning and disinfection at the outer surface, the inner surface and the interface were 100%, 91.25% and 93.75%, respectively. There was no significant difference in the disinfection effect at the outer surface and interface of simple respirators between the two groups （both P 〉 0.05）. But the two kinds of cleaning and disinfections at the inner surface of the respirators were significantly different as regards the qualified rate （P 〈 0.05）. Conclusion For the disinfection of simple respirator, the mechanical cleaning and disinfection is better than the manual cleaning and disinfection.
