- the hub 20 can be reliably positioned by contacting the first sealing member 62.
- the first connector member 40 has a first inclined piece 43 inclined toward the inner peripheral surface 40i side, and the first inclined piece 43 rotates toward the outer peripheral surface side when the housing 50 slides toward the first inclined piece 43 side.
- the second lock portion 2L includes the second inclined piece 13 of the second connector member 10 that is located outside the first inclined piece 43 and is inclined toward the inner peripheral surface 10i. The slide of the first connector member 40 is locked by engaging with the first connector member 40, and the first inclined piece 43 contacts the second inclined piece 13 by rotating the first inclined piece 43 outward. By rotating the second inclined piece 13 outward, the engagement between the second inclined piece 13 and the first connector member 40 is released, and the first connector member 40 can be slid.
- the slide of the first connector member 40 is locked by the first inclined piece 43 and the second inclined piece 13 that are inclined toward the inner peripheral surfaces 40i and 10i, the person brings the first inclined piece 43 and the second inclined piece 13 outward. It becomes difficult to rotate. As a result, the first connector member 40 can be prevented from sliding due to human operation.
- the access member 101 has a passage claw portion 111 protruding to the outer peripheral side, and the passage claw portion 111 moves the first lock portion 1L to the outer peripheral surface side of the first connector member 40, thereby the housing 50 by the first lock portion 1L. It is possible to release the lock.
- the lock of the housing 50 can be released, and the lock can be released with a simple configuration.

Abstract
Description
特許文献1に記載の構造では、人が操作することでニードルの先端を露出させることができる。その結果、人がニードルの先端に接触することができるという問題がある。特許文献2では、常にボディー内にニードルの先端が位置し、付勢部材を有することで、アダプタを押し込まなければニードルを接続できず、液体を注入することが困難であるという問題があった。
好ましくは、ハウジングには、ハウジングのスライドがロックされているときにニードルの先端を収納する空間が設けられており、ハウジングは、空間を封止する第一封止部材を有し、ニードルは第一封止部材を貫通している。
図1は、実施の形態1に係るコネクタの側面図である。図1で示すように、コネクタ1はコネクタ本体としての第二コネクタ部材10と、第二コネクタ部材10の内側に嵌り合うコネクタガイドとしての第一コネクタ部材40とを有する。第一コネクタ部材40の先端はアクセス部材101に嵌り合う。第二コネクタ部材10の後端はシリンジ201に嵌り合う。
図8は、アクセス部材に接続された後のコネクタの側面図である。図8で示すように、矢印2で示す方向に位置が移動する。これにより、第一コネクタ部材40がコネクタキャップ110に嵌合する。
液体215は、シリンジ201内に封入されており、この液体215は、外部に漏洩させたくない任意の液体である場合に、上記のコネクタ1は優れた効果を有するたとえば、抗がん剤などの危険薬剤のほか、病原菌、耐性を持つと困る菌などを含む液体215を移送する場合に、コネクタ1を用いることができる。具体的には、シリンジ201から薬剤バッグへ薬液を移送する場合、輸液ラインからサンプリング用の空のシリンジへ輸液を移送する場合、病原菌を含む液状の検体採取具から検査キットへ検体を移送する場合などに、コネクタ1が好適に用いられ得る。また、トリクロロエチレンなどの危険溶剤、または、環境ホルモンを含む液体215を移送する場合にも、コネクタ1を用いることができる。
