PROBLEM TO BE SOLVED: To provide an infusion pump which allows an occlusion sensor to detect an occlusion state of an infusion tube when an opening/closing cover is closed even when the infusion tube of any size among two or more kinds of infusion tubes having different diameters is mounted on the infusion pump.SOLUTION: The infusion pump includes occlusion sensors 52 and 53 arranged at a tube mounting part 50, for detecting the occlusion state inside an infusion tube 200 by checking the change of the outer diameter of the infusion tube 200. At an opening/closing cover 5, pressurizing members 452 and 453 are arranged at positions corresponding to the occlusion sensors 52 and 53. The pressurizing members 452 and 453 have an energizing member 441 for pressing a part of the infusion tube 200, using the pressurizing members 452 and 453, to the side of the occlusion sensors 52 and 53 in the state of closing the opening/closing cover 5.COPYRIGHT: (C)2013,JPO&INPIT【課題】直径が異なる複数種類の輸液チューブの内の何れのサイズの輸液チューブが輸液ポンプに装着されても、開閉カバーを閉じると閉塞センサは輸液チューブの閉塞状態を検出できる輸液ポンプを提供する。【解決手段】チューブ装着部50に配置されて輸液チューブ200の外径の変化をみることで輸液チューブ200内の閉塞状態を検出する閉塞センサ52,53と、を有し、開閉カバー5には、閉塞センサ52,53に対応する位置に押圧部材452,453が配置され、押圧部材452,453は、開閉カバー5を閉じた状態で押圧部材452,453を閉塞センサ52,53側に輸液チューブ200の一部を押し当てるための付勢部材441を有する。【選択図】図11
