PROBLEM TO BE SOLVED: To provide an easily detachable infusion pump in which the pressure on the infusion tube in between the roller and the stator can be automatically adjusted at an optimum pressure to accurately secure the flow rate without adding new component elements such as springs, etc., to the infusion pump main body. SOLUTION: This cassette for infusion pump comprises a base member 10 with an engaging part to engage with a movable engaging member 104 equipped on an infusion pump so as to move in the direction rectangular against the rotation axis of a roller 101 by the contact with a cover rotatably equipped on the infusion pump and a movable member 20 engaged with the roller 10, movable in a limited range in at least one radial direction of the roller 10, and having an arc shape part capable of pressing an infusion tube 31 in between the roller 10 and itself and has a groove part to place the infusion tube 31 along the infusion sending passage in a condition connecting the base member 10 and the movable member 20. The flexible infusion tube 31 is placed in the groove to elastically restrict movement of the movable member. The cassette is equipped on the infusion pump. |
