A rapid infusion pump with a maximum flow rate of 6 L/h was designed experimentally using a micro electromagnetic linear actuator, and its effectiveness was evaluated by comparing with that of a commercial Power Infuser under preset flow rates of 0.2, 2, and 6 L/h. The flow rate, air detection sensitivity, occlusion response time, quantitative determination of hemolysis, and power consumption of the infusion devices were extensively investigated using statistical analysis methods (p < 0.05). The experimental results revealed that the flow rate of the designed infusion pump was more stable and accurate, and the hemolysis was significantly less than that of the Power Infuser. The air detection sensitivity and the power consumption could be comparable to that of the Power Infuser except the occlusion response time. The favorable performance made the designed infusion pump a potential candidate for applications in pre-hospital fluid administration.
使用微型电磁线性致动器通过实验设计了一种最大流速为6L/h的快速输液泵，并通过在0.2、2和6L/h的预设流速下与商用动力输液器进行比较来评估其有效性。使用统计分析方法（p<0.05）广泛研究了输液装置的流速、空气检测灵敏度、阻塞响应时间、溶血定量测定和功耗。实验结果表明，所设计的输液泵的流速更稳定、更准确，并且溶血明显少于动力输液器。除了阻塞响应时间外，空气检测灵敏度和功耗与动力输液器相当。良好的性能使所设计的输液泵成为院前液体给药应用的潜在候选者。
