A fluid transfer device may include a body member and a fluid transfer tip, wherein the fluid transfer tip may include a tapered friction fitting for a corresponding hub. The fluid transfer device also may include a disconnecting member having a front portion and a rear portion and engagement features operating between the disconnecting member and the body member. The engagement features engage with one another to inhibit the front portion of the disconnecting member from moving relative to the fluid transfer tip. The fluid transfer device is arranged such that upon application of a force to the rear portion of the disconnecting member, the disconnecting member deforms so that the engagement features are no longer in engagement with one another. This allows the front portion of the disconnecting member to move relative to the fluid transfer tip and subsequently release the hub from the friction fitting.

Fluid transfer devices

A disconnecting mechanism includes a main body including a fluid transfer tip having a tapered surface to form a friction fit with a corresponding connector. The lever member includes a threaded portion to enable the corresponding connector part to be connected to the fluid transfer tip by a screw fit in addition to the friction fit, and an actuator portion to actuate release of the friction fit. In a first pivotal position, the threaded portion has a first position close to the fluid transfer tip to engage with an outer thread or rim of the corresponding part and thereby form the screw fit in addition to the friction fit. In a second pivotal position, the threaded portion has a second position further away from the fluid transfer tip to disconnect the screw fit and the actuator portion is moved forward to push the connector part and release the friction fit.

Disconnecting mechanisms

A fluid transfer device or connection with a fluid transfer tip that has a tapered friction fitting for a corresponding hub. A lever member is pivotally mounted to move relative to the fluid transfer tip. A latch such as a screw thread is mounted on the lever member to engage the hub and provide a positive connection e.g., screw fit in addition to the friction fitting. The lever member may optionally be resiliently biased by a spring. The hub is disconnected from the tip by pivoting the lever member to release the positive connection with the hub and to subsequently release the hub from the friction fitting.

Fluid transfer connection

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.
