介绍了一种电渗微泵的结构及其驱动原理，研究了其对不同生理溶液的渗透特性。模拟眼内房水引流装置，利用电渗微泵对三种生理溶液进行测试，通过改变电压，测试定量体积的溶液，记录时间得出相应流速，用Origin Proporable软件对数据拟合得出压电流速曲线，结果表明电压对液体流动速度的影响成正比。人眼可承受最大5V电压，此时该测试微泵传输液体流量每分钟可达到十几微升，通过分析5V以内微泵对溶液的渗透性能，结合正常眼内房水引流速度，确定合理的驱动电压设计值，这将对未来制作实际可用的房水引流装置和器件产生指导意义。

The structural and drive principle of a electroosmotic micropump was introduced in this paper,and its os-mosis for different physiological solution was investigated. By modeling the humor aquosus drainage system in eyes, the pump was used to test three physiological solution. By changing the supply voltage and recording the experimen-tal time for certain volume of solution,then the corresponding velocity of the flow can be calculated. The data was fitted to obtain the voltage-velocity curves by using Origin Proporable software. The conclusion shows that the voltage has a direct proportion with the velocity of flow. The velocity of the flow could reach to about ten microliter when the voltage is 5 V which is the maximum tolerable value in eyes of human. By analyzing the osmotic permea-bility of the pump within 5 V and combining the normal flow rate of aquosus drainage,the reasonable supply voltage can be designed accordingly which will be significant for making the practical aquosus drainage system and devices in the future.
