Claims (6)
- 雄型コネクタを雌型コネクタとの係合から外す方法であって、前記雄型コネクタは、雌型コネクタと係合する遠位端と、近位端と、遠位弁と、近位弁とを含み、前記雌型コネクタは、前記雄型コネクタと係合する近位端と、遠位端と、内部弁とを含み、前記方法は、
前記雄型コネクタの前記近位端の流体から前記雄型コネクタと前記雌型コネクタの間の境界面を隔離するために、前記雄型コネクタの前記近位端で前記雄型コネクタ内の前記近位弁を閉鎖することと、
前記境界面から前記境界面に残る流体を引き出すために、前記雄型コネクタと雌型コネクタの前記境界面に部分的真空状態を形成することとを含み、
前記部分的真空は、前記雄型コネクタの減圧手段によって形成され、前記減圧手段は、前記近位弁と、前記雄型コネクタの前記遠位端を通る流体の流れを制御する前記遠位弁とを含み、前記境界面に残る前記流体が前記部分的真空によって空隙の中へ引き込まれるまで、前記遠位弁は開放したままである、方法。 - 部分的真空状態を形成するステップの前に、前記雌型コネクタの前記内部弁を閉鎖するステップをさらに含む、請求項1に記載の方法。
- 部分的真空状態を形成するステップの後に、前記雄型コネクタの前記遠位端で前記遠位弁を閉鎖するステップをさらに含む、請求項2に記載の方法。
- 前記部分的真空状態を形成するステップが、前記雄型コネクタ内に部分的真空状態を形成することと、前記境界面にある流体を雄型コネクタ内に引き込むこととを含む、請求項2又は請求項3に記載の方法。
- 医療用流体の流れのために前方接触面及び内部弁を有する雌型ルアー・コネクタと接続する雄型ルアー・コネクタであって、前記雄型ルアー・コネクタは、
前記雌型ルアー・コネクタと係合し、境界面を確立するように構成される遠位端、及び近位端を有する管状筐体と、
前記雄型コネクタが前記雌型コネクタとの係合から外れ前記雌型弁が閉鎖している期間に、前記管状筐体の前記遠位端に部分的真空状態を形成する減圧手段とを備え、
前記減圧手段が、前記雄型及び雌型コネクタが非係合状態である間、前記境界面から前記境界面に残る流体を引き出し、
前記減圧手段は、前記管状筐体の前記近位端を通る流体の流れを制御する近位弁と、前記管状筐体の前記遠位端を通る流体の流れを制御する遠位弁とを含み、前記境界面に残る前記流体が前記部分的真空によって空隙の中へ引き込まれるまで、前記遠位弁は開放したままである、雄型ルアー・コネクタ。 - 医療用流体の流れのための経路を確立するために前方接触面及び内部弁を有する雌型コネクタと接続する雄型コネクタであって、前記雄型コネクタは、
前記雌型ルアー・コネクタと係合し、境界面を確立するように構成される遠位端、及び近位端を有する管状筐体と、
前記管状筐体の前記遠位端を通る流体の流れを制御するのに使用するために配置される遠位弁台座と、
前記管状筐体内に配置され、前記遠位弁台座を越える流体の流れを阻止するために前記遠位弁台座に係合する遠位弁部材を有する内部プラグと、
前記遠位弁台座に係合するように前記内部プラグを付勢するために前記管状筐体内に配置され、且つ、遠位弁が閉鎖すると第1の容積を有し、前記遠位弁が開放すると、前記第1の容積より小さい第2の容積を有し、流体が通過する内部可変容積空隙を有する、弾性部材とを備え、
前記弾性部材が、前記雌型コネクタの前記雄型コネクタとの係合により前記弾性部材空隙が前記第2の容積に移り、前記雌型コネクタが前記雄型コネクタとの係合から外れることにより前記弾性部材空隙が前記第2の容積から前記第1の容積に移り、これにより部分的真空状態を形成するように配置され、
前記部分的真空は、減圧手段によって形成され、前記減圧手段は、前記遠位弁部材と、前記管状筐体の前記近位端を通る流体の流れを制御する近位弁部材とを含み、前記境界面に残る前記流体が前記部分的真空によって空隙の中へ引き込まれるまで、前記遠位弁は開放したままである、雄型コネクタ。
