目的比较两种清洗方法对医用橡胶吸耳球的清洗效果。方法将集中回收的医用橡胶吸耳球600件,随机分为2组,分别采用清洗机清洗法和手工清洗法,对清洗质量进行目测、残留液检测和隐血试验检测。结果 3种检测方法,清洗机清洗合格率达分别为98.0%、90.0%和86.7%;手工清洗合格率分别为97.3%、96.7%和94.3%,两种清洗方法合格率差异有统计学意义(P<0.01)。结论手工清洗法效果明显优于清洗机清洗法。
Objective To compare the cleaning effects of two kinds of cleaning methods on medical rubber suction ear balls. Methods A total of 600 medical rubber aspirating balls were collected and randomly divided into two groups. The washing quality and the occult blood test were detected by the washing machine cleaning method and manual washing method respectively. Results The results showed that the pass rates of washing and washing machines were 98.0%, 90.0% and 86.7%, respectively. The pass rates of manual washing were 97.3%, 96.7% and 94.3% respectively. There was a significant difference in pass rates between the two methods P <0.01). Conclusion Manual cleaning method is obviously better than washing machine cleaning method.
