Objective:To explore the effect of alkaline cleaning agent combined with ultrasonic cleaning machine in cleaning equipment in gynecology.Methods:300 suction head and vaginal speculum were selected.They were randomly divided into A group,B group,C group.A group was given the medical soft brush washing and rinsing with water cannons,and then they were putted into the automatic cleaning machine.B group was soaked for 10 minutes with pH neutral potent multi enzyme cleaning agent,and then washed with A method.C group was shaked for 10 minutes in the ultrasonic vibration machine with alkaline cleaning agent,and then washed with A method.We compared the cleaning effect.Results:After cleaning,the qualified rate of A group was 58%;the qualified rate of B group was 90%;the qualified rate of C group was 100%.Conclusion:Cleaning effect was the best of ultrasound machine vibration plus alkaline cleaning agent plus high-pressure water washing brush.%目的：探讨碱性清洗剂联合超声清洗机清洗妇科复用器械的效果。方法：选择吸引头、窥阴器共300个，随机分成A、B、C 3个组，A组用医用软毛刷刷洗后用高压水枪冲洗，然后放入全自动清洗机清洗；B组用pH值中性的强效多酶清洗剂浸泡10 min后再用A组方法清洗；C组放入已加碱性清洗剂的超声机震动10 min再用A组方法清洗，比较清洗效果。结果：清洗后，A组合格率58%，B组合格率90%，C组合格率100%。结论：采用超声机震动＋碱性清洗剂+毛刷+高压水枪冲洗，其清洗消毒效果最佳。
