PROBLEM TO BE SOLVED: To provide a storage tool excellent in storage property and convenience, and allowing compactly storing a flexible long body part in a wound state, included in a medical instrument, and appropriately performing correction of bending tendency formed on the long body part by an easy operation.SOLUTION: A storage tool 100 includes: a tubular storage part 110 including a lumen in which a body part 210 of a guiding catheter 200 can be stored, and a base end opening which is communicated with the lumen and into which the body part of the guiding catheter can be inserted, and storing the body part in a wound state and a guide part for guiding drawing of the body part from the storage part through the base end opening. The storage part holds the guiding catheter so as to arrange a central axis of the body part in a position near a winding shaft of the storage part than a tangent line of an outline of the wound storage part, and the guide part bends the body part to a radial direction outside of the wound storage part.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】医療用器具に備えられる可撓性のある長尺状の本体部を巻回した状態でコンパクトに収納することができ、かつ、長尺状の本体部に付いた曲がり癖の矯正を簡単な操作で適切に行うことができる収納性および利便性に優れた収納具を提供する。【解決手段】収納具100は、ガイディングカテーテル200の本体部210を収納可能な内腔と、内腔に連通しガイディングカテーテルの本体部を挿入可能な基端開口部とを備え、本体部を巻回した状態で収納する管状の収納部110と、基端開口部を介した収納部からの本体部の引き出しをガイドするガイド部と、を有し、収納部は、当該収納部に本体部を収納した状態において、巻回した当該収納部の外形線の接線よりも当該収納部の巻回軸に近い位置に本体部の中心軸が配置されるようにガイディングカテーテルを保持し、ガイド部は、巻回した収納部の径方向外側へ向けて本体部を湾曲させる。【選択図】図2
