      • 摘要:
        目的 探究输液介质对输液泵流速的影响。
        方法 随机抽取10台输液泵，采用去离子水、氯化钠溶液、葡萄糖溶液和肠道外营养液分别进行流速检测，输液泵流速设为30 mL/h，检测方法依照《医用输液泵校准规范》。
        结果 对于输液器A，流速不受输液介质的影响，均符合质控要求标准；对于输液器B，输液介质为去离子水、氯化钠溶液和葡萄糖溶液时，流速误差在质控要求标准内，而输液介质为营养液时，流速误差超出质控要求标准。
        结论 输液器和输液介质对输液泵流速均有影响，根据使用的输液介质进行流速校准对于降低输液泵在使用过程中的医疗风险具有重要意义。

         

        Abstract:
        Objective To investigate the impact of different infusion media on the flow rate of infusion pumps.
        Methods Ten infusion pumps were randomly selected and tested for infusion rates using deionized water, saline solution, glucose solution, and parenteral nutrition solution. The infusion flow rate was set at 30 mL/h, and the testing methodology conformed to the standards for the calibration and quality control of syringe pumps and infusion pumps.
        Results For infusion set A, the infusion rate was unaffected by the infusion media, remaining within the acceptable quality control standards. For infusion set B, when infused with deionized water, saline solution, and glucose solution, the infusion errors were within the quality control standards. However, when using parenteral nutrition solution as the infusion medium, the infusion error exceeded the acceptable quality control standards.
        Conclusion Both the infusion set and the infusion medium can affect the flow rate of infusion pumps. It is crucial to calibrate the flow rate according to the specific infusion medium to reduce medical risks associated with infusion pumps during clinical use.
