Different cleaning methods of toothed medical devices and their effect evaluation

目的探讨有齿类新器械不同清洗方法及效果。方法选取2013年1月~2014年12月的330件新止血钳,随机分为手工清洗组、机械清洗组和混合清洗组,每组各110件。分别用手工刷洗法、全自动机械喷淋清洗法、超声机清洗+手工刷洗法清洗。清洗后用放大镜分别检测洁净度合格率。结果三组的洁净度合格率分别是96.4%、86.4%和97.3%。手工清洗组和混合清洗组差异无统计学意义(P>0.05);手工清洗组和机械清洗组、机械清洗组和混合清洗组均有显著性差异(P<0.01)。结论手工刷洗法和超声机清洗+手工刷洗法均能提高新止血钳清洗效果。

Objective To explore the different cleaning methods of toothed medical devices and their effects. Methods A total of 330 new hemostatic clamps were selected from January 2013 to December 2014 and randomly divided into manual cleaning group, mechanical cleaning group and mixed cleaning group,each group of 100 pieces.Respectively, by manual brushing method, automatic mechanical spray cleaning method, ultrasonic cleaning＋manual brushing method for cleaning.After cleaning, used magnifying glass to detect cleanliness pass rate. Results The qualified rate of cleanliness of the three groups was 96.4%, 86.4% and 97.3%. There was no significant differenco between the manual cleaning group and the mixed cleaning group （P〉0.05）;there were significant differences between the manual cleaning group and the mechanical cleaning group, the mechanical cleaning group and the mixed cleaning group （P〈0.01）.Conclusion Manual brushing method and ultrasonic cleaning＋manual brushing method can improve the new hemostatic clamps cleaning effect.
