Abstract
An injector device includes a housing for receiving a medicament cartridge; a needle unit comprising a needle; and a first sleeve slideable along a longitudinal axis of the housing from a first position, in which the first sleeve conceals the needle, to a second position, in which the needle is exposed from an end of the first sleeve, the first sleeve configured to engage the needle unit so that, during use, movement of the first sleeve from the first position to the second position moves the needle unit from a primary position to a secondary position, in which secondary position the needle unit locates over an end of a medicament cartridge, wherein the device further comprises a second sleeve arranged to move telescopically with respect to the first sleeve, the first sleeve extending from the second sleeve when the first sleeve is in the first position.
