Fluid transfer devices

摘要

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.

1. A fluid transfer device comprising:
a fluid chamber in communication with a male connector tip, the male tip being tapered to form a friction fit when inserted in a corresponding female hub; a disconnecting member moveable relative to 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, wherein the disconnecting member is biased into the first position by a resilient bias; and a catch means arranged to catch the female hub after it has been released from the friction fit by the disconnecting member moving towards the second position, wherein the catch means is arranged to be automatically released by the disconnecting member moving from the second position back to the first position under said resilient bias.
