Abstract:

Objective To invent a stainless steel twist traction ring and to discuss its effectiveness in the quality inspection of luminal devices cleaning. Methods A stainless steel twist traction ring is invented and used for inspection of the cleaning quality of luminal devices. Its effectiveness in quality inspection of luminal devices cleaning was evaluated by comparing with the effect of visual + light source magnification method,the probe gauze method,and the ATP biofluorescence method. Results In the inspection of the cleaning quality of luminal devices A,there were differences in the cleaning quality pass rates between the twist traction ring method,the visual + light source magnification method and the ATP biofluorescence method,respectively,and the differences were statistically significant（P<0.010）. In the pair-wise comparisons,the visual inspection + magnification method had the highest pass rate,with a statistically significant difference in pass rate from the other 2 groups（P<0.017）. There were no statistically differences in pass rates between the twist traction ring method and the ATP biofluorescence method（P>0.017）. In the cleaning quality inspection of luminal devices B,there were statistically significant differences in pass rates of the 4 cleaning quality inspection methods（P<0.01）,and in the pair-wise comparisons,the visual inspection + magnification method had the highest pass rate,with a statistically significant difference in pass rate from the other 3 groups（P<0.008）. Conclusion The stainless steel twist traction ring method can detect unqualified devices that cannot be detected by visual + light source magnification methods in the quality inspection of luminal devices cleaning. Its detection is comparable to that of the probe gauze method and the ATP biofluorescence method. But its operation is easier and more widely applicable than the probe gauze method,and it saves money compared to the ATP biofluorescence method.

摘要：

目的 制作不锈钢麻花牵引圈并探讨其在管腔器械清洗质量检查中的应用效果。方法 将制作的不锈钢麻花牵引圈用于管腔器械清洗质量的检查,通过与目测+光源放大镜法、探条纱布法、ATP生物荧光法做比较,评价其在管腔器械清洗质量检查中的效果。结果 A类空腔器械清洗质量检查中,麻花牵引圈法、目测+放大镜法和ATP生物荧光法的清洗质量检查合格率差别有统计学意义（P<0.010）,两两比较,目测+放大镜法合格率最高,与其他2组的检查合格率差异具有统计学意义（P<0.017）,麻花牵引圈法与ATP生物荧光法的检查合格率差异无统计学意义（P>0.017）。B类空腔器械清洗质量检查中,4种清洗质量检查方法合格率差异具有统计学意义（P<0.010）,两两比较,目测+放大镜法合格率最高,与其他3组的检查合格率差异具有统计学意义（P<0.008）。麻花牵引圈法、探条纱布法和ATP生物荧光法的检查合格率差异无统计学意义（P>0.008）。结论 不锈钢麻花牵引圈在管腔器械清洗质量检查中,能发现目测+放大镜法无法检出的不合格器械,其检测效果与探条纱布法、ATP生物荧光法相当,比ATP生物荧光法节省费用,但操作较金属探条法便捷,适用范围更广。
