PROBLEM TO BE SOLVED: To provide an introduction device of a medical linear member to a medical tube, capable of filling a medical tube with fluid by preventing a guide wire from entering into a fluid path, when the guide wire is inserted into an insertion path.SOLUTION: An introduction device 10 including a linear member path 43 and a fluid path 45, comprises: a tubular member 50 that has a tubular shape with no hole formed at a mid-flow in the axial direction, and is disposed with a first gap 57 spaced from the inner diameter of the linear member path a seal member 55 and a valve member 60 that is disposed with a second gap 58 spaced from a proximal end of the tubular member and seals a proximal-side opening of the linear member path. The distal end of the fluid path 45 is opened so as to communicate to the first gap 57 in the proximal end side with respect to the seal member 55, where the first gap 57 is communicated to the interior of the tubular member via the second gap 58.COPYRIGHT: (C)2016,JPO&INPIT【課題】挿通路にガイドワイヤを挿入していく際に、流体通路にガイドワイヤが入り込むことを防止し、流体を医療用チューブに注入できる、医療用チューブへの医療用線状部材の導入装置を提供する。【解決手段】この導入装置10は、線材通路43と流体通路45を備え、軸方向途中に穴が形成されていない管状をなし、第1間隙57を設けて配置された管状部材50と、シール部材55と、管状部材基端に対して第2間隙58を設けて配置され、線材通路の基端側開口を封止する弁部材60とを有し、流体通路45の先端部は、管状部材途中の、シール部材55よりも基端側の第1間隙57に連通するように開口し、かつ、第1間隙57は第2間隙58を介して管状部材内に連通している。【選択図】図7
