Objective. To develop a new type infusion set and apply it to the clinic, as well as explore its effectiveness in the prevention from needle stick injuries. Methods. A total of 200 inpatients who were in need of intravenous infusion with a disposable infusion needle were included and randomly divided into two groups: intervention group and control group. Disposable infusion needles with a separation-free safety tube were used in the intervention group, whereas conventional ones were used in the control group. Then, effects of the two types of infusion sets were observed and compared. Results. As for the operation time for infusion, it was () seconds in the intervention group and () seconds in the control group, with the difference statistically significant (). Besides, the exposure time of the needles after infusion in the intervention group was () seconds while () seconds in the control group; the difference between which was statistically significant (). In terms of the time for needle disposal, () seconds was required in the intervention group, while for the control group, it took () seconds, and the difference between two groups was of statistical significance as well (). Nevertheless, there was no statistically significant difference in the accidental slip rate of the needles as that turned out 0% in both groups (). It was worth noting that the block rate of the disposed needles in the intervention group was 100%. Conclusion. The separation-free safety tube on the disposable infusion needle could instantly block the sharp needle after infusion, which reduces the needle exposure time and lowers the risk of needle stick injuries. In the meantime, the safety tube is convenient to use, and its application can shorten the time for infusion and needle disposal, consequently improving the working efficiency of nurses. As the new type safety tube has above advantages and would not raise the risk of needle slippage, it is worthy of clinical promotion.

一次性输液针免分离安全管的研制与应用。

客观的。研制新型输液器并应用于临床，探讨其预防针刺伤的效果。方法。纳入需要一次性输液针静脉输液的住院患者200例，随机分为两组：干预组和对照组。干预组使用带有免分离安全管的一次性输液针，对照组使用常规输液针。然后观察并比较两种输液器的效果。结果。至于输液的手术时间是（)干预组秒数和 ()秒，对照组差异有统计学意义(）。此外，干预组输液后针头暴露时间为（)秒同时 ()对照组秒数；之间的差异具有统计学意义（）。就针头处理时间而言，（干预组需要)秒，而对照组则需要 ()秒，两组间差异也有统计学意义(）。然而，针头意外滑落率没有统计学上的显着差异，两组均为 0%（）。值得注意的是，干预组废弃针头堵塞率为100%。结论。一次性输液针上的免分离安全管可以在输液后立即阻挡锋利的针头，减少针头暴露时间，降低针刺伤的风险。同时，安全管使用方便，它的应用可以缩短输液和针头处理的时间，从而提高护士的工作效率。由于新型安全管具有上述优点，且不会增加针滑脱的风险，值得临床推广。
