<P>PROBLEM TO BE SOLVED: To provide a micropump from which a tube unit and a control unit can be removed. <P>SOLUTION: The micropump 1 is provided with a tube unit 2 which includes an elastic tube 50, fingers 40-46, a tube guide frame 17 retaining the tube 50 and the fingers 40-46, and a third machine frame 16; and a control unit 3 which includes a cam 20, a rotor 70 transmitting torque to the cam 20, and piezoelectric elements 82, 83, and includes a vibrator 80 including a projection 81a at a longitudinal direction end, a control circuit 60, a battery 61, a first machine frame 14 retaining the cam 20, the rotor 70, the vibrator 80, the control circuit 60, and the battery 61, and a second machine frame 15. The tube unit 2 and the control unit 3 can be removed. The vibrator 80 vibrates when alternating voltages are applied to the piezoelectric elements 82, 83. Torque is applied to the rotor 70 from the projection 81a. The cam 20 sequentially presses the fingers 40-46 to transport liquid. <P>COPYRIGHT: (C)2010,JPO&INPIT |
