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 300V ，the maximum water delivery flowrate is as 104.6g/min ，and the pressure difference is as 1.53kPa of piezoelectric pump with flexible valvular valves in conical channels，which are much beter 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 300V ，the maximum blood transport flowrate is as 86.4g/min ，the pressure difference is as 1.45kPa ，and the damage to erythrocytes and platelets is small during blood transport.
