PROBLEM TO BE SOLVED: To provide an infusion pump having closing fingers capable of sufficiently pressing an infusion tube and completely closing its inner cavity even if it shows dimension error.SOLUTION: This invention comprises: a pump main body having a tube clamp face formed with a groove for arranging an infusion tube a cover member attached to the pump main body in such a manner that it may be oscillated in respect to the pump main body and having a protrusion fitted into the tube groove a plurality of fingers for pressing the infusion tube while being forwarded or retracted in respect to the infusion tube installed in the tube groove and a driving part for forwarding or retracting the plurality of fingers, the invention is constituted by a plurality of closing fingers 521 for depressing the infusion tube to close its inner cavity and a plurality of liquid feed fingers for depressing the infusion tube in such a degree as not to close the inner cavity. The closing fingers 521 comprise a main body part 541 extending in one direction and a movable part 542 installed at the main body part 541, enabled to be reciprocated in one direction to press the infusion tube and the movable part 542 is biased in such a direction as to be protruded from the main body part 541.COPYRIGHT: (C)2015,JPO&INPIT【課題】寸法誤差が生じた場合でも、輸液チューブを十分に押圧し、内腔を完全に閉鎖することができる閉鎖フィンガーを備えた輸液ポンプを提供する。【解決手段】輸液チューブを配置する溝が形成されたチューブ取付面を有するポンプ本体と、ポンプ本体に対して揺動自在に取付けられるとともに、チューブ溝に嵌まる突条部を有するカバー体と、チューブ溝に装着された輸液チューブに対し、進退しつつ押圧する複数のフィンガーと、複数のフィンガーを進退させる駆動部と、を備え、輸液チューブを押しつぶし、内腔を閉鎖する複数の閉鎖フィンガー521と、輸液チューブの内腔を閉鎖しない程度に押圧する複数の送液フィンガーとで構成され、閉鎖フィンガー521は、一方向に延びる本体部541と、本体部541に装着され、一方向に往復動可能で輸液チューブを押圧する可動部542とを備え、可動部542は、本体部541から突出する方向に付勢されている。【選択図】図4
