改良注水耗材连接在消化内镜诊疗中的应用

Application of modified disposable consumables for flushing in digestive endoscopy

目的 探讨灭菌注射用水和一次性输液管改良注水耗材连接在消化内镜诊疗的应用。方法 采用自身前后对照方法,2019年12月前使用传统注水技术,2020年1月开始使用改良注水技术,即灭菌注射用水直接连接一次性输液管,代替复用水瓶(将灭菌注射用水倒入后)和送水管储水及送水,比较改良前后冲洗液微生物培养结果、耗材成本及护士耗费时间。结果 改良前后冲洗液微生物培养结果均合格。改良前复用水瓶需集中清洗后送供应室灭菌,循环利用需等2d后,每人次内镜诊疗注水耗材连接总成本(29.81±4.65)元,连接、安装和拆卸时间(8.15±1.42)min;改良后总成(3.46±0.51)元,连接、安装及拆卸时间共(2.00±0.22)min,操作简单,取材方便。结论 改良注水耗材连接操作简单,节约成本,减少护士耗时,保障诊疗安全。

Objective To explore the effect of application of a modified disposable flushing consumables for sterilised water flushing in digestive endoscopy. Methods Self-comparison method was applied in this study. The traditional flushing device was used in digestive endoscopy prior to December 2019. From January 2020,a modified flushing was applied,of which sterilised flushing water was fed through a disposable flushing pipe and made it free from the reuse of the storage bottle that held the sterilised water in the traditional flushing device. The results of microbial culture,cost of consumables and time required for preparation of the flushing were compared between pre- and post-modification of the flushing device. Results The samples of flushing water before and after the device modification had both passed the microbial culture tests. With the traditional flushing,it took 2 days for collection,cleaning and re-use of a bottle after the proper sterilisation process,and the time required for assembly and disassembly of the modified flushing was about (8.15±1.42) minutes with the cost of consumables at (29.81±4.65) Yuan. While of the modified flushing with disposable consumables,the overall cost of the consumables was (8.15±1.42) Yuan,and it took about (2.00±0.22) minutes for assembly and disassembly the device. The modified flushing was simple to operate and the consumables were readily available. Conclusions The improved disposable consumables for flushing are easy and convenient to handle. They are cost effective and time saving and safe for the digestive endoscopy.
