PROBLEM TO BE SOLVED: To provide a conversion adaptor, a measurement unit, a medical device, and a training device capable of improving detection accuracy of a measuring device.SOLUTION: A conversion adaptor 20 is disposed in a front stage of a measuring device 2 which includes a first through hole 3 capable of receiving a flexible linear body 1 and first sheath 21, has the linear body 1 supported by an inner wall of the first through hole 3, and measures a compressive force and tensile force in a longitudinal axis direction applied to the linear body 1 depending on the degree of curvature of the linear body 1. The conversion adaptor 20 is provided with a body part 23 in which a second through hole 30 is formed. The second through hole 30 includes: a first part 31 located in a subsequent stage end side and capable of receiving the first sheath 21 and a second part 32 located in a front stage end side and capable of receiving a second sheath 22 which is larger in the external diameter than the first sheath 21. When the linear body 1 is let through the second through hole 30 with the tip of the linear body received in the second sheath 22, the second sheath 22 for receiving the tip of the linear body 1 can be replaced by the first sheath 21.COPYRIGHT: (C)2014,JPO&INPIT【課題】計測装置の検出精度を向上させることが可能な変換アダプタ、計測ユニット、医療装置および訓練装置を提供する。【解決手段】変換アダプタ20は、可撓性を有する線状体1および第1鞘21を受け入れ可能な第1貫通孔3を有し、第1貫通孔3の内壁により線状体1を支持し、線状体1の湾曲の度合いに応じて線状体1に作用する長手軸方向の圧縮および引張力を計測する計測装置2の前段に設けられる。変換アダプタ20は、第2貫通孔30が形成された本体部23を備える。第2貫通部30は、後段端部側に位置し第1鞘21を受け入れ可能な第1部分31と、前段端部側に位置し第1鞘21よりも大きな外径を有する第2鞘22を受け入れ可能な第2部分32とを含む。線状体1の先端を第2鞘22に収納した状態で第2貫通孔30に通すことで、線状体1の先端を収納する第2鞘22を第1鞘21に置き換えることが可能である。【選択図】図4
