目的研究病房传呼器手柄消毒方法。方法采用棉拭涂抹采样和细菌检验方法对不同方法消毒后的传呼器手柄消毒效果进行了检测。结果医院使用的传呼器手柄污染菌数平均为38 cfu/cm2。用75%酒精对传呼器手柄作擦拭消毒至少2遍,对其表面上自然菌消除率为98.38%,消毒后平均存活菌数为0.62 cfu/cm2。用含有效氯500mg/L的含氯消毒剂溶液擦拭消毒,对其表面上自然菌平均消除率为98.39%,消毒后平均存活菌数为0.58cfu/cm2。结论医院使用的传呼器手柄污染严重,用75%酒精和含氯消毒剂作擦拭消毒均可达到满意的效果。
Objective To study the method of sterilizing the ward pager handle. Methods Cotton swab smear and bacterial test methods were used to test the disinfection effect of the pager handle after disinfection. Results The average number of bacteria in the pager handle used in the hospital was 38 cfu / cm2. 75% alcohol on the pager handle wipe disinfection at least 2 times, on its surface natural bacteria elimination rate of 98.38%, after disinfection, the average number of viable bacteria was 0.62 cfu / cm2. The disinfectant was disinfected with chlorine disinfectant solution containing effective chlorine 500mg / L. The average removal rate of natural bacteria on the surface was 98.39% and the average number of viable bacteria after disinfection was 0.58cfu / cm2. Conclusion The pager used in the hospital was heavily polluted. Satisfactory results were achieved with wipe disinfection with 75% alcohol and chlorine-containing disinfectants.
