PURPOSE:To continue to discharge a fixed quantity even when used for a long time by providing a tube set member and recovering a flexible tube to a circular shape when the liquid is sucked. CONSTITUTION:A section 11a of a movable tube set piece 11 is formed so that its inner diameter width matches the outer periphery of a flexible tube 1 when it becomes a circle, and the depressed flexible tube 1 is recovered to a circular shape and sucks the liquid when the movable tube set piece 11 is moved. Accordingly, the flexible tube 1 becomes a circle when sucking, thus it sucks the liquid quickly. In addition, the flexible tube 1 is recovered to a complete circle and can continue to discharge a fixed quantity as a pump. |
