PROBLEM TO BE SOLVED: To provide an infusion pump capable of correctly supplying a drug by an infusion tube by preventing deflection of an opening/closing cover when a healthcare worker mounts the infusion tube to a lower part of a body and covers the infusion tube with the opening/closing cover.SOLUTION: The infusion pump includes: an opening/closing cover 5 which can be opened and closed centering on a hinge 2H having a rotation axis along a transverse direction and covers a tube mounting part 50 and a liquid supply drive part 60 by being closed and a tube clamp part 270 which is pressed by the opening/closing cover 5 when the opening/closing cover 5 is closed and closes a part of the infusion tube 200 mounted on the tube mounting part 50. The opening/closing cover 5 includes: a first hook member 452 which is arranged at one end part of the opening/closing cover 5 and can be hooked to the side of the tube mounting part 50 and a second hook member 453 which is arranged at the other end part of the opening/closing cover 5 and can be hooked to the side of the tube mounting part 50.COPYRIGHT: (C)2013,JPO&INPIT【課題】医療従事者が、輸液チューブを本体の下部分に装着して開閉カバーにより輸液チューブを覆う際に、開閉カバーが撓むことを防止して、薬剤を輸液チューブにより正しく送液することができる輸液ポンプを提供する。【解決手段】横方向に沿った回転軸を有するヒンジ2Hを中心にして開閉可能であり、閉じることでチューブ装着部50と送液駆動部60を覆う開閉カバー5と、この開閉カバー5を閉じると開閉カバー5により押されてチューブ装着部50に装着された輸液チューブ200の一部を閉塞するチューブクランプ部270を有し、開閉カバー5は、開閉カバー5の一端部に配置されてチューブ装着部50側に掛けることが可能な第1フック部材452と、開閉カバー5の他端部に配置されてチューブ装着部50側に掛けることが可能な第2フック部材453を有する。【選択図】図4
