Abstract

A fluid transfer assembly comprise a first open end for connection to a syringe and a second open end for receiving a vial having a closure element. The second open end is adapted to engage and open the closure element and permit fluid in the vial to be transferred to the syringe from the vial, for example by gravity acting on the fluid in the vial.

Claims

1. An injection kit comprising:

a fluid transfer assembly comprising;

means for connection to a syringe;

means for receiving a vial having a closure element,

wherein the receiving means is adapted to engage and open the closure element and permit fluid in the vial to be transferred to the syringe from the vial, wherein the connection means comprises an end of the fluid transfer assembly which is open and dimensioned to fit over or in an open end of the syringe body which is opposite a needle end of the syringe, wherein the fluid transfers in use from the vial to the syringe under the force of gravity, when the receiving means is located above the connection means;

a syringe;

a delivery device including a delivery sub-assembly and a drive sub-assembly, which are both adapted to be attached to the syringe, and operate together to deliver the fluid from the syringe; and

a base station which is adapted to receive the drive sub-assembly and reset the drive by moving it from its second position to its first position and reset the release mechanism such that when actuated again it releases the drive.

2. The kit of claim 1 wherein the base station comprises an attachment to hold the delivery sub-assembly.
