• a rotary disk disposed in the arc, the rotational center of the rotary disk aligning with the center of the arc;
• a plurality of push pins disposed between the elastic tube and the rotary disk;
• and
• a rotary push plate arranged on an upper side of the rotary disc for facilitating fluid flow inside the elastic tube from an inlet to an outlet by pushing the plurality of push pins sequentially, the rotary push plate including:
• a plurality of protrusions that place a bias on the elastic tube by pushing the plurality of push pins sequentially;
• and
• a recess disposed between the plurality of protrusions that releases the bias from the elastic tube;
• wherein
