Abstract: Described is a medicament cartridge comprising a housing adapted to contain a syringe containing a medicament, a shield telescopically coupled to the housing and translatable relative to the housing between a retracted position and an extended position, and a data storage device including medicament data.

Abstract: Described is a medicament delivery device comprising a housing adapted to contain a syringe, a pain reduction device coupled to the housing, a coupling mechanism disposed in the housing and operably coupled to the pain reduction device, and a drive mechanism disposed in the housing and operably coupled to the coupling mechanism. Activation of the drive mechanism actuates the coupling mechanism to activate the pain reduction device.

Abstract: Described is an autoinjector comprising a front case having a first rib and a second rib, and a rear case telescopically coupled to the front case and having latch arms adapted to engage the first rib and the second rib. When the front case is in a first position relative to rear case, the latch arms are engaged to the first rib. When the latch arms disengage the first rib, the front case translates to a second position relative to the rear case, an axial distance between the front case and the rear case increases relative to the first position, the latch arms engage the second rib.

Abstract: Described is a syringe comprising a barrel, a stopper slidably arranged within the barrel, a needle arranged on a distal end of the barrel, a plunger coupling coupled to the stopper and adapted to releasably engage a plunger, and a needle retraction mechanism adapted to retract the needle into the barrel.

Abstract: Described is an autoinjector comprising a case, a drive carriage disposed in the case, and a plunger coupled to the drive carriage. The plunger is adapted to releasably engage a needle retraction mechanism in a syringe. Translation of the drive carriage in a distal direction relative to the case causes the plunger to engage the needle retraction mechanism and translation of the drive carriage in a proximal direction relative to the casing case the plunger to needle refraction mechanism the stopper.
