PROBLEM TO BE SOLVED: To facilitate mounting of a balloon catheter by inflating a balloon even by physically-disabled hand fingers.SOLUTION: The operation tool for operating a reservoir set 56 comprised of a balloon-inflating reservoir 57, a flexible tube 58, and a clamp 59 on the flexible tube 58, comprises a base member 1 and a lever member 2. The base member 1 includes a first storage part 15 for storing the reservoir 57, and a second storage part 16 for storing the clamp 59. The lever member 2 is engaged with the base member 1 so as to vertically freely move relative to the base member 1 from an upper first position to a lower second position and to freely rotate relative to the base member from the second position to a third position. When the lever member 2 moves from the first position to the second position, a first pressing part 25 of the lever member compresses the reservoir 57 stored in the first storage part 25 to deliver fluid to the balloon. When the lever member 2 is rotationally turned from the second position to the third position, a second pressing part 26 deforms the clamp 59 stored in the second storage part 26 of the base member 1, to a blocking position.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2019,JPO&INPIT【課題】 不自由な手指でもバルーンを拡張でき、バルーンカテーテルの装着を容易にする。 【解決手段】 バルーン拡張用のリザーバ５７、可撓管５８及び可撓管５８上のクランプ５９からなるリザーバセット５６を操作する操作具を、ベース部材１とレバー部材２とで構成する。ベース部材１は、リザーバ５７を収容する第１収容部１５と、クランプ５９を収容する第２収容部１６とを備える。レバー部材２は、ベース部材１に上方の第１位置から下方の第２位置へ垂直方向に相対移動自在に、また第２位置から第３位置へ相対回動自在にベース部材１に係合する。レバー部材の第１押圧部２５は、レバー部材２が第１位置から第２位置への移動時に、第１収容部２５に収容したリザーバ５７を圧縮してバルーンに流体を送出させる。第２押圧部２６は、レバー部材２が第２位置から第３位置へ回動時に、ベース部材１の第２収容部２６に収容したクランプ５９を遮断位置へ変形させる。【選択図】 図９
