摘要： A fluid transportation system includes an elastic tube, a tube frame to which the tube is attached such that the tube forms a circular arc, a first cam and a second cam disposed inside the tube, and fingers which radially extend from a rotation center in the space between the tube and the first and second cams. The first and second cams produce a first condition where the fingers are all released and a second condition where at least one of the fingers constantly closes the tube. The first and second cams sequentially press the fingers, and the fingers sequentially repeat closure and release of the tube so that fluid can continuously flow.
