A micropump including a tube unit and a control unit. The control unit has a plurality of fingers. A cam sequentially presses the plurality of fingers from an inlet side to an outlet side of the tube. A drive unit gives rotation force to the cam, a control circuit unit controls operation of the drive unit, and a device frame holds the plurality of fingers, the cam, the drive unit, and the control circuit unit. A reservoir communicates with an inlet port of the tube; and a power source supplies power to the control circuit unit, wherein the tube unit is detachably attached to the control unit substantially in the horizontal direction with respect to the rotation surface of the cam and attached to the inside of a space produced by the device frame.

The micropump according to claim 1, further comprising: a reservoir housed in the tube unit. 9. The micropump according to claim 1, further comprising: a reservoir and a power source, the reservoir and the power source being housed in the tube unit. 10. A micropump comprising: a tube having an inlet and an outlet;a tube unit including a tube guide frame and the tube, the tube guide frame defining a first protrusion, a second protrusion, a circular-arc shaped portion disposed between the first protrusion and the second protrusion, and a tube guide groove into which the tube is inserted;wherein the tube guide frame has an inner wall and an outer contour, the outer contour comprising an external surface of the first protrusion, the circular-arc shaped portion, and the second protrusion;a control unit that is non-fixedly attachable to and detachable from the tube unit such that the tube unit is entirely received within the control unit and secured therein by a cover that is fixedly attached to the control unit with the outlet of the tube passing through the cover, the control unit including an outer wall facing the external surfaces of the protrusions, a cam, and a plurality of fingers operatively associated with the cam;the control unit defining a first recess on one side of the cam for receipt of the first protrusion and a second recess on the opposite side of the cam for receipt of the second protrusion;wherein the tube guide groove extends from the inner wall, towards the outer wall, and along a path that borders the outer contour; andwherein the plurality of fingers are located between the tube and the cam after the control unit is attached to the tube unit. 11. The micropump according to claim 10, wherein the tube unit has a reservoir fluidly communicating with the tube. 12. The micropump according to claim 11, wherein the reservoir is attachable to and detachable from the tube unit. 13. The micropump according to claim 11, wherein the reservoir has a re-sealable port for introducing fluid into the reservoir. 14. The micropump according to claim 11, wherein the tube unit has a power source mounted thereto which supplies power to the control unit. 15. The micropump according to claim 14, wherein the power source is attachable to and detachable from the tube unit. 16. The micropump according to claim 10, further comprising: a reservoir housed in the tube unit. 17. The micropump according to claim 10, further comprising: a reservoir and a power source, the reservoir and the power source being housed in the tube unit.
