PROBLEM TO BE SOLVED: To provide a connector in which fine adjustment of an aperture of a hemostatic valve is facilitated without the risk of accidental opening of the hemostatic valve.SOLUTION: A connector includes: a hemostatic valve 21 a hemostatic valve pressure member 25 and an elastic body (a coil spring 22) for energizing the hemostatic valve pressure member 25. The hemostatic valve pressure member 25 is movable to a first position where the member is separated backward from the hemostatic valve 21 by a prescribed distance, a second position where the member is abutted on the hemostatic valve 21 but keeps the hemostatic valve 21 closed without opening the valve, and a third position where the member pressurizes the hemostatic valve 21 forward and releases the valve. A return from the second position to the first position of the hemostatic valve pressure member 25 is blocked by a stopper (a projection 28) arranged between the two positions. Resistance force with the stopper acts on the hemostatic valve pressure member 25 in a push-in operation from the first position to the second position.COPYRIGHT: (C)2013,JPO&INPIT【課題】止血弁が不測に開放するおそれがなく、止血弁の細かい開度調節が容易なコネクタを提供する。【解決手段】止血弁21と、止血弁押圧部材25と、止血弁押圧部材25を付勢する弾性体(コイルバネ22)とを有するコネクタである。止血弁押圧部材25は、止血弁21から所定距離だけ後側に離間した第1位置と、止血弁21に当接するが止血弁21を開放することなく閉じたままにする第2位置と、止血弁21を前側に押圧して解放する第3位置に移動可能である。止血弁押圧部材25は、第2位置から第1位置への戻りが当該2つの位置の間に配置したストッパ(凸部28)で阻止され、第1位置から第2位置への押し込み操作時に当該ストッパによる抵抗力が止血弁押圧部材25に作用する。【選択図】図1
