PROBLEM TO BE SOLVED: To make it possible that any of a plurality of flow channels, which are defined respectively for a plurality of branch pipes, can be left unconnected by a simple and easy operation.SOLUTION: A medical connector comprises: a holder member including a holder body which defines a hollow section, and a plurality of port parts which are provided on outer walls of the holder body, define respective flow channels connected to the hollow section, and are connected to medical instruments and a cock member which is at least partially received into the hollow section of the holder body and changes the connection state between the plurality of flow channels defined by the plurality of port parts by rotating relative to the holder member while sliding on inner walls of the holder body. The medical channel is deformable between a first configuration in which any of the plurality of flow channels is left unconnected and a second configuration in which at least two of the plurality of flow channels are connectable, by moving the cock member in a center axis direction of the holder body.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 簡易な操作で、複数の分岐管にそれぞれ区画された複数の流路がいずれも接続しない状態とすることが可能となる。【解決手段】 中空部を区画するホルダ本体、及び該ホルダ本体の外壁に設けられ、前記中空部と接続する流路をそれぞれ区画し、医療器具と接続される複数のポート部を備えるホルダ部材と、前記ホルダ本体の前記中空部に少なくとも一部が収容され、前記ホルダ本体の内壁と摺動しながら前記ホルダ部材に対して回転することにより前記複数のポート部が区画する複数の流路間の接続状態を変化させるコック部材と、を備え、前記コック部材が前記ホルダ本体の中心軸方向に対して移動することにより、前記複数の流路がいずれも接続しない第1の形態と、前記複数の流路のうち少なくとも2つが接続可能な第2の形態と、に変形可能である。【選択図】図1
