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.

Injector device

An injector device comprising an elongate housing having a proximal end and a distal end, and configured to receive a container of medicament, a needle sleeve mounted within the housing and moveable between an extended position in which the needle sleeve at least partially extends from the distal end of the housing, and a retracted position in which the needle sleeve is received further within the housing than in the extended position, a piston rod moveable longitudinally within the housing, a piston spring configured to bias the piston rod towards a distal end of the housing to engage a container of medicament when received within the housing, and a release mechanism configured to control actuation of the piston rod. The release mechanism comprises a locking arm moveable between a locked position in which the locking arm is in cooperating engagement with the piston rod and prevents movement of the piston rod, and a release position in which the locking arm is out of engagement with the piston rod so that the piston rod is free to move longitudinally within the housing. The needle sleeve is configured such that movement of the needle sleeve from the extended position to the retracted position causes the locking arm to move from the locked position to the release position.
