PROBLEM TO BE SOLVED: To provide a tube pump capable of increasing a discharge rate by using a tube made of a material of low flexibility and low resilience and capable of being manufactured in compact size even as a finger type pump.SOLUTION: A tube pump 1 comprises: tubes 42A, 42B; base members 31, 32; at least three or more finger members 60; and a driving mechanism for driving each of the finger members 60. Each of the finger members 60 has a tube pressing-and-bending part 632 that presses and bends the tube. The driving mechanism drives each of the finger members 60 in such a manner that the tube pressing-and-bending part 632 presses the tube from a suction side toward a discharge side of the tube so as to move in sequence to the bent position. The base members 31, 32 have tube receiving members 310, 320 fitted thereon which are deformed together with the tubes so as to support bending thereof when the tubes are pressed by the tube pressing-and-bending part 632.SELECTED DRAWING: Figure 7 |
