Patent ID: 8267571

Claim:
A system for making an injectable mixture using at least one pulverulent component and at least one liquid component, the system comprising: an injector including a piston and a cylinder, the cylinder having a proximal end for receiving the piston, a distal end for delivering the injectable mixture, a mixing element manoeuvrable by a user, at least one transfer channel arranged displaceably in the cylinder, and a first engagement element at the distal end of the cylinder, wherein the cylinder contains a measured amount of the at least one pulverulent component; and a reservoir containing a measured amount of the at least one liquid component and having a second engagement element configured for connection with the first engagement element at the distal end of the cylinder to provide for transfer of the at least one liquid component into the cylinder of the injector, wherein, during or following a mixing of the at least one pulverulent component and the at least one liquid component within the cylinder by the mixing element, the at least one transfer channel is axially displaced within the cylinder and through the distal end of the cylinder to remove gas from within the cylinder through one or more apertures in the at least one transfer channel.
