Claims (4)
- オスコネクタ接続部及び医療器具接続部を有するハウジングと、前記オスコネクタ接続部を閉塞する頭部及び該頭部に連なる胴部を有する弁体と、を備える医療用コネクタにおいて、
前記弁体の胴部は、前記ハウジングの内部に形成された収容凹部に配置されており、
前記オスコネクタ接続部へのオスコネクタの接続にて、該オスコネクタにより、前記弁体の頭部が、前記胴部を収縮させつつ押し込まれ、前記オスコネクタ内の流体流路を、前記収容凹部の外側に形成された流体連通路を通じて、前記医療器具接続部内の流体流路に連通させると共に、前記胴部が前記収容凹部に覆われ、
前記弁体の胴部は、前記頭部と反対側の端部に開口する中空部を形成する蛇腹状の周壁を有し、
前記ハウジングの収容凹部の底面には、前記オスコネクタの接続時に前記蛇腹状の周壁が折り畳まれると前記中空部の前記頭部側端面に当接し、該蛇腹状の周壁のさらなる変形を抑制する支持突起が形成されていることを特徴とする医療用コネクタ。 - 前記弁体の外周面には、前記オスコネクタの接続時に前記頭部を傾けて、前記オスコネクタ内の流体流路を、前記流体連通路を通じて前記医療器具接続部内の流体流路に連通させる切欠きが形成されており、
前記弁体の胴部と前記ハウジングの収容凹部との間には、前記胴部の周方向の回転を防止する回転防止手段が設けられている、請求項1に記載の医療用コネクタ。 - 前記ハウジングは、該ハウジングの外部と前記弁体の中空部とを連通させる通気路を有する、請求項1又は2記載の医療用コネクタ。
- 前記弁体の胴部の外周面には、前記蛇腹状の周壁の前記頭部側端部において、前記ハウジングの収容凹部に液密に摺接するシール突起が周設されている、請求項1〜3のいずれか一項に記載の医療用コネクタ。
