Abstract
An infusion pump has a primary finger with an inclined surface, which is obliquely inclined to an advancing and retracting direction, and a secondary finger with an inclined surface, which is slidable relative to the inclined surface of the primary finger. When the primary finger is advanced, the secondary finger is retracted in proportion to the variation (increasing) in an entire width of an infusion tube, and when the primary finger is retracted, the secondary finger is advanced in proportion the variation (decreasing) in the entire width of the infusion tube. This configuration can suppress the occurrence of any gap between a tip surface of the secondary finger and an outer peripheral surface of the infusion tube in the advancing and retracting process of the primary finger. Consequently, this prevents the infusion tube from meandering, and suppresses the reduction in the accuracy of the rate of infusion.
