史密斯注射泵高低阻塞报警的调整

目的：通过改变微量注射泵的阻塞报警阈值，确保临床微量注射用药的安全。方法：通过分析微量注射泵的设计得到产生阻塞报警的原理，对于不同类型的微量注射泵应用不同的调试方法，改变影响报警阈值的因素，达到改变报警阈值的目的；结果：经设备剂量检测调试后的微量注射泵95％能达到规定的安全值，极少数微量注射泵需进行不同的处理，以满足临床应用安全。结论：改变注射泵的报警影响因素可以达到改变报警阈值的目的。

Adjustment of alarm of threshold value of Smith micro-medicinal infusion pump

Objective： To ensure the safety of the rational drug use, to change the threshold value of the micro-medicinal infusion pump. Methods： Through analyzing the principle of the micro-medicinal infusion pump produces stress, for the different type of the pump use different modify way, find the reasons of produces stress and change threshold value; Results： through change 95% the pump limens can return normal value, the others need next treat, meet clinic require. Conclusions： To change the reasons of create warning to change threshold value of micro-medicinal infusion pump.
