Abstract

An injector device is configurable between a safe state and an operable state and comprises a housing having a distal end and a proximal end; a medicament cartridge disposed within the housing; a needle unit comprising a needle and being disposed in the distal end of the housing; a sleeve displaceable along a longitudinal axis of the device between a first position in which the sleeve conceals the needle and a second position in which the needle is exposed from an end of the sleeve; a locking mechanism configured to prevent displacement of the sleeve when the device is in the safe state; and a button disposed in the proximal end of the housing, the button being configured to switch the device between the safe state and the operable state by releasing the locking mechanism when the button is pressed from an initial position into a depressed position during use.
