    • 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.
    • 输液泵具有主指状物,其具有倾斜的倾斜表面,其倾斜地朝向前进和后退方向,以及具有相对于主指状物的倾斜表面可滑动的倾斜表面的次级手指。 当主指状物前进时,辅助手指与输液管的整个宽度的变化(增加)成比例地缩回,并且当主指缩回时,次级手指按比例(递减) 输液管的整个宽度。 这种构造可以抑制在主指的前进和缩回过程中二次手指的尖端表面和输注管的外周表面之间的任何间隙的发生。 因此,能够防止输液管曲折,能够抑制输液速度的精度降低。
