PROBLEM TO BE SOLVED: To provide a medical device that is highly safe while comprising a separable part.SOLUTION: A medical device comprises a rotary member 100 that is rotatably connected to a unit connector tip part 72 and that surrounds an outer periphery of the unit connector tip part 72 when the unit connector tip part 72 and a unit connector base end part 90 are connected. The rotary member 100 comprises an applying part 102 that comes into contact with the unit connector tip part 72 to apply a force. The unit connector tip part 72 comprises a force receiving part 77 that comes into contact with the applying part 102 to receive the force from the applying part 102. The medical device can shift from a first state in which the force is not transmitted from the applying part 102 to the force receiving part 77 and the rotary member 100 can rotate independently with respect to the unit connector tip part 72, to a second state in which the applying part 102 comes into contact with the force receiving part 77 so as to be capable of transmitting the force and the unit connector tip part 72 can rotate in association with the rotation of the rotary member 100.COPYRIGHT: (C)2016,JPO&INPIT【課題】切り離しが可能な部位を備えつつも、安全性が高い医療用デバイスを提供する。【解決手段】ユニットコネクタ先端部72に回転可能に連結されるとともに、ユニットコネクタ先端部72およびユニットコネクタ基端部90が接続された状態においてユニットコネクタ先端部72の外周を囲む回転部材100を備え、当該回転部材100が、ユニットコネクタ先端部72に接触して力を作用させる作用部102を備え、ユニットコネクタ先端部72が、作用部102と接触して作用部102から力を受ける受力部77を備え、作用部102から受力部77へ力が伝達せずにユニットコネクタ先端部72に対して回転部材100が独立して回転可能な第1状態から、作用部102が受力部77に力を伝達可能に接触して、回転部材100の回転に伴ってユニットコネクタ先端部72が回転可能な第2状態へ移行可能である医療用デバイスである。【選択図】図5
