In order to achieve the reagents’precision pipetting in medical instruments,a micropump was designed with valveless plunger structure. The mechanical structure and kinematics equations of the micropump were illustrated in detal. Besides,finite ele-ment analysis was executed to the plungers with different materials. The experimental results show that the precision of the micropump is high,and its variability coefficient is less than 1% when the pump-intake is 20 μL.
