Abstract
An injection device () comprising a housing (), a needle hub () slidable within the housing (), a needle () having a distal end piercing tip () and a proximal end piercing tip (), the needle hub being moveable from a first position wherein the distal end piercing tip () is within the housing to a second position wherein the distal end piercing tip () extends outwardly of the housing (), a spring () biasing the needle hub () towards the first position, and a cartridge receiving member () mounted within the housing (), and a plunger rod assembly () for exerting pressure on the cartridge receiving member () to move the cartridge () and the needle hub () from the first position to the second position, the plunger rod assembly () and the cartridge receiving member () being arranged such that when the cartridge rod assembly is pushed, a rotational movement is imparted to the cartridge receiving member () to thereby prevent access to the cartridge after injection.
