    • A first member (10) and a second member (20) are coupled to each other in a coupling portion (100). The first member includes, on the opposite side to the coupling portion, a main portion (51) that is connectable to a counterpart connector. The main portion and the second member are in communication with each other via a flow channel (102). One of the first member and the second member includes an outer cylindrical portion (30), and the other of the first member and the second member includes an inner cylindrical portion (40). In the coupling portion, the inner cylindrical portion is fitted in the outer cylindrical portion. The outer cylindrical portion includes a first engagement portion (31) and an abutment portion (35). The inner cylindrical portion includes a second engagement portion (41) that engages the first engagement portion, and a leading end (45) that is a front end of the inner cylindrical portion in a direction in which the inner cylindrical portion is fitted into the outer cylindrical portion. As a result of the first engagement portion and the second engagement portion engaging each other, the leading end of the inner cylindrical portion abuts against the abutment portion of the outer cylindrical portion along a central axis (101).

    • A first male member (110) and a tubular portion (30) are in communication via first to third holes (21 to 23). A liquid channel (211) and a gas channel (212) of the second male member (210) are in communication with the tubular portion. First to third channels (41 to 43) are formed in a stopcock (40). The stopcock can switch between a first rotation position at which the first channel puts the first hole and a syringe connection portion (32) of the tubular portion in communication, and a second rotation position at which the first channel puts the liquid channel and the syringe connection portion in communication. When the stopcock is at the second rotation position, the second hole and the gas channel are in communication via the second channel, and the first male member and an inner cavity (45) of the stopcock are in communication via the third hole and the third channel. A first hydrophobic filter (50a) is provided in the channel that connects the first male member and the gas channel when the stopcock is at the second rotation position, and a second hydrophobic filter (50b) is provided in the channel that connects the first male member and the air supplying member (410) that is connected to the stopcock when the stopcock is at the second rotation position.
    • 第一阳构件(110)和管状部分(30)经由第一至第三孔(21至23)连通。 第二阳构件(210)的液体通道(211)和气体通道(212)与管状部分连通。 第一至第三通道(41至43)形成在旋塞(40)中。 活塞可以在第一通道将第一孔放置在第一旋转位置和连通的管状部分的注射器连接部分(32)之间切换,第二旋转位置在第一旋转位置处,第一通道将液体通道和注射器 通信中的连接部分。 当活塞处于第二旋转位置时,第二孔和气体通道经由第二通道连通,第一阳构件和活塞的内腔(45)经由第三孔连通,第三孔 渠道。 当所述活塞处于所述第二旋转位置时,在所述通道中设置第一疏水性过滤器(50a),所述通道连接所述第一阳部件和所述气体通道,并且在所述通道中设置第二疏水过滤器(50b),所述第二疏水过滤器 构件和空气供应构件(410),当活塞处于第二旋转位置时,连通到旋塞的空气供应构件(410)。
