不同清洗器械方法对鲁沃夫润滑油污染情况的影响

Effect of different methods cleaning equipment by machine washing on Ruhof lubricating oil pollution

目的 观察鲁沃夫润滑油在器械上油过程中被污染情况.方法 将鲁沃夫润滑油原液按1：15配制成2桶,每天从回收手术器械中抽取400件,分为两组,经手洗、机洗目测洁净后分别放进鲁沃夫润滑油浸泡30 s上油.每日对鲁沃夫润滑油抽样送检做细菌培养,比较两组润滑油细菌培养结果.结果 手洗组润滑油合格率为78.57%,无细菌生长23次,机洗组润滑油合格率为50%,无细菌生长9次;两组比较差异有统计学意义（P＜0.01）.结论 手洗清洁优于机洗,可以延长鲁沃夫润滑油使用周期,节约用量,减少成本.

Objective To observe the polluted Ruhof lubricating oil with two kinds of cleaning ml, only then tested them after the examination aseptic situation. The 400 recycling of surgical instruments were randomly divided into hand washing group and machine washing group （each group was 200 ）, The recycling of surgical instruments were respectively soaked into the oil for 30s after hand washing and machine washing to oil.Adapting Ruhof lubricating oil made bacterial culture by setting people and time to check the sample, and compared the results. Results The hand washing group：percent of pass was 78.5 %, no bacterial growth was 23 times;The machine washing group： percent of pass was 50%, no bacterial growth was 9 times. There was significant difference between the two groups （P 〈 0. 01 ）. Conclusions Hand washing is better than machine washing, it can extend the life cycle of Ruhof lubricating oil, save consumption and reduce costs.
