- 内壁を有する筒状部と、前記内壁に開口する第一開口部を有するとともにこの第一開口部から前記筒状部の外方に向かって貫通して形成された第一分岐流路と、前記内壁に開口する第二開口部を有するとともにこの第二開口部から前記筒状部の外方に向かって貫通して形成された第二分岐流路と、前記内壁に開口する第三開口部を有するとともにこの第三開口部から前記筒状部の外方に向かって貫通して形成された第三分岐流路とを備える本体と、前記筒状部の内周側に装着されるとともに前記筒状部の軸周り方向に回動可能とされ、回動することによって前記第一分岐流路、前記第二分岐流路、前記第三分岐流路の連通および遮断を切換える弁体とを有する医療用活栓において、
前記弁体には、前記第一分岐流路および前記第三分岐流路に連通可能な第一連通流路と、前記第一連通流路が前記第一分岐流路と前記第三分岐流路との双方に連通しているとともに前記第二分岐流路との連通が遮断されているときに、前記第二分岐流路と前記第三分岐流路との双方に連通可能であるとともに前記第一分岐流路との連通が遮断される状態を採り得る第二連通流路とが形成され、
前記弁体には、前記第一連通流路と前記第二連通流路とが前記弁体内で連通するのを妨げる隔壁部が形成され、
前記第一連通流路は、前記弁体の外周に周方向に形成された第一溝部であり、前記第二連通流路は、前記第一溝部に並行になるように前記弁体の外周に周方向に形成された周方向溝部と、前記弁体の軸方向に沿って形成された軸方向溝部とを有する第二溝部であり、
前記軸方向溝部は、その一端が前記周方向溝部に連通するとともに前記一端から前記弁体の軸方向に延び、その他端が前記第一溝部が形成されている前記弁体の軸方向位置まで達するように形成された、医療用活栓。 - 請求項1に記載の医療用活栓において、前記第一分岐流路と前記第二分岐流路は、前記筒状部を挟んで対向して配置されており、前記弁体の回動中心軸は、前記第一開口部の中心と前記第二開口部の中心とを結ぶ直線からオフセットしていることを特徴とする、医療用活栓。
- 請求項1または2に記載の医療用活栓において、前記第三分岐流路内には、前記隔壁部に液密的に当接可能に配置されているとともに、前記隔壁部から前記第三分岐流路の流路軸方向に延設された第二隔壁部が設けられていることを特徴とする、医療用活栓。
