    • A fluid transfer device such as a syringe may include a fluid chamber in communication with a male connector tip. The male connector tip is tapered to form a friction fit when inserted in a corresponding female hub. A disconnecting member, e.g., in the form of a lever member has a front surface moveable along the male connector tip between a first position proximal to the fluid chamber and a second position spaced from the first position towards a distal end of the male connector tip so as to release the friction fit. A catch is arranged to catch the female hub after it has been released from the friction fit by the lever member moving towards the second position. The catch may be released when the lever member pivots back towards the first position under the resilient bias of a spring tongue.
    • 诸如注射器的流体转移装置可以包括与阳连接器尖端连通的流体室。 阳连接器尖端是锥形的,当插入相应的母毂中时形成摩擦配合。 断开构件,例如杠杆构件的形式具有前表面,该前表面可沿着阳连接器尖端在靠近流体室的第一位置与从第一位置朝向阳连接器尖端的远端间隔开的第二位置 以释放摩擦配合。 排扣被设置成在通过杠杆构件向第二位置移动而从摩擦配合件释放之后抓住母毂。 当杆构件在弹簧舌的弹性偏压下向第一位置枢转时,卡扣可以被释放。
