摘要:

为提高柔性瓣膜阀压电泵的输液性能,结合锥流道的流阻不等特性设计了一种柔性瓣膜阀锥流道压电泵。输水性能测试结果表明,驱动电压(峰峰值)为300 V时,柔性瓣膜阀锥流道压电泵的最大输水流量、压力差分别为104.6 g/min和1.53 kPa,较柔性瓣膜阀直流道压电泵均得到较大提高。柔性瓣膜阀锥流道压电泵的输血试验结果表明,驱动电压(峰峰值)为300 V时,最大输血流量、压力差分别为86.4 g/min和1.45 kPa,输血过程中对血细胞的破坏较小。

Abstract:

To improve the infusion performance of piezoelectric pump with flexible valvular valves, a piezoelectric pump with flexible valvular valves in conical channels was designed combined with unequal flow resistance characteristics of conical channels. The water delivery performance results show that, when the driving peak-to-peak voltage is 300 V, the maximum water delivery flowrate is as 104.6 g/min, and the pressure difference is as 1.53 kPa of piezoelectric pump with flexible valvular valves in conical channels, which are much better than those of piezoelectric pump with flexible valvular valves in straight channels. The blood transport tests results of piezoelectric pump with flexible valvular valves in conical channels show that when the driving peak-to-peak voltage is 300 V, the maximum blood transport flowrate is as 86.4 g/min, the pressure difference is as 1.45 kPa, and the damage to erythrocytes and platelets is small during blood transport.

Key words: piezoelectric pump, flexible valvular valve, conical channel, flowrate, pressure difference, blood transport
