PROBLEM TO BE SOLVED: To provide a connector, which prevents inflow of washing water to a throat tube side in washing of a suction catheter regardless of the suitability of an operators operation, and a suction catheter device provided with the same.SOLUTION: The connector 1 includes: an inner cylinder portion 10 to which the suction catheter 22 is inserted an outer cylinder portion 16 having a first port 11 connected to the throat tube, a second port 12 to which the inner cylinder portion 10 is movably installed, and a washing port 13 to which washing water is supplied and which is opened and closed by the insertion of the inner cylinder portion 10 and a valve element portion 20 provided in the inside of the outer cylinder portion 16 closer to the tip beyond the washing port 13. The inner cylinder portion 10 has a first projection 7 which presses the valve element portion 20 from the base end side when the suction catheter 22 is moved forward to put it in an opened state a second projection 8 which presses the valve element portion 20 from the tip side when the suction catheter 22 is moved backward to maintain the closed state and an opening 9 which communicates with the washing port 13 when the second projection 8 abuts on the valve element portion 20.COPYRIGHT: (C)2013,JPO&INPIT【課題】操作者の操作の適否に関係なく、吸引カテーテルの洗浄時に気管チューブ側へ洗浄水が流入しないコネクタ、および、それを備えた吸引カテーテル装置を提供する。【解決手段】コネクタ1は、吸引カテーテル22が挿通される内筒部10と、気管チューブと接続する第1ポート11、内筒部10が移動自在に装着される第2ポート12、および、洗浄水を供給する洗浄ポート13を有する外筒部16と、洗浄ポート13よりも先端側の外筒部16の内部に設けられ、内筒部10の挿通によって開閉する弁体部20とを備え、内筒部10は、吸引カテーテル22を前進させた際に弁体部20を基端側から押圧して開放状態にする第1突起部7と、吸引カテーテル22を後退させた際に弁体部20を先端側から押圧して閉塞状態を維持する第2突起部8と、第2突起部8が弁体部20と当接した際に洗浄ポート13と連通する開口部9とを有する。【選択図】図2
