双腔串联压电胰岛素泵性能分析与试验
Analysis and test on PZT insulin pump with dual-chambers in series
摘要
Abstract
In order to reduce the cost and simplify the structure of insulin pumps, the piezoelectric ( PZT) pump was adopted in insulin injection to replace common one equipped with a step motor. The working principle and two operating modes, such as direct and indirect transfusions of insulin were analyzed for PZT insulin pump. The performance of valve-less piezoelectric pumps and those with active valve or passive valves was compared; then a PZT pump with dual-chambers in series was proposed for insulin injection so as to improve the pump output pressure. A prototype of such a pump was produced and its performance with three different cut-off valves was measured under both direct and indirect transfusion modes. The measured performance parameters included both opening pressure and flow rate. The results show that the indirect transfusion mode exhibits a better flow and pressure performance than the direct transfusion one. The maximum flow rate in indirect mode reaches 810 mL/min when the voltage and frequency of driving signal are 100 V and 210 Hz. The umbrella-shape valve gives rise to a higher flow rate.关键词
