软式内镜使用S弯精细测漏法的效果分析

Effectiveness of S‑curve leakage testing method on flexible endoscope

摘要:

探讨S弯精细测漏法对软式消化内镜器械检查及出现中高级故障的影响。采用便利抽样法，选取空军军医大学第一附属医院消化内镜中心的内镜测漏检测情况作为研究资料。将2016年7月—2017年12月采用常规测漏法的58条内镜设为对照组（检测29 116次），2018年1月—2019年6月采用S弯精细测漏法的56条内镜设为观察组（检测28 112次）。对照组和观察组测漏后，结果显示，观察组检出角度异常的比例高于对照组［65.6%（59/90）比40.4%（36/89），χ2=11.330，P<0.001］，但检出电荷耦合器组件损坏和插入部破损等中高级故障的比例低于对照组［0.04%（10/28 112）比0.08%（23/29 116），χ2=4.680，P=0.030］，观察组的总体维修费用低于对照组（31.37万元比94.26万元）。可见，S弯精细测漏法能早期发现内镜低级故障，例如角度异常，减少内镜中高级故障的发生，明显降低维修成本，有助于降本增效。

Abstract:

To investigate the effects of the S-curve leakage testing method on the detection of flexible endoscope and occurrence of medium to high-level faults of flexible endoscope. A convenience sampling method was used to study the information of endoscopic leak detection at the digestive endoscopic centre of the First Affiliated Hospital of Air Force Medical University. From July 2016 to December 2017, 58 endoscopes which received conventional leakage testing were set as the control group (29 116 tests). From January 2018 to June 2019, 56 endoscopes which received S-curve leakage testing were set as the observation group (28 112 tests). The results showed that the detection proportion of angular abnormalities in the observation group was higher than that in the control group [65.6% (59/90) VS 40.4% (36/89), χ2=11.330, P<0.001]. However, the detection proportion of medium to high-grade faults such as damaged charge coupled device (CCD) components and broken insertion section in the observation group was lower than that in the control group [0.04% (10/28 112) VS 0.08% (23/29 116), χ2=4.680, P=0.030]. Moreover, the overall maintenance cost was lower in the observation group than that in the control group (313.7 thousand yuan VS 942.6 thousand yuan). It is indicated that the S-curve leakage testing method can detect low-level endoscopic faults early such as angular abnormalities, and reduce the occurrence of medium to high-level endoscopic faults, which contributes to cost reduction and efficiency increase.
