Claim 18:
19. A system comprising:
a syringe containing a medicament; and
an autoinjector comprising:
a case configured to receive the syringe;
a slidable member that is movable axially within the case to cause at least a portion of the syringe to move axially when the syringe is disposed within the case for dispensing the medicament through a needle of the syringe;
a locking member configured to prevent actuation of the slidable member when the autoinjector is in a pre-dispense configuration;
a sleeve coupled to a distal end of the case and surrounding at least a portion of a needle of the syringe when the syringe is disposed within the case;
an elongate member extending proximally from the sleeve and configured to deflect the locking member to allow actuation of the slidable member;
two drive springs coupled to the slidable member and configured to apply a biasing force that acts on the slidable member to move the slidable member distally within the case, wherein the two drive springs are parallel to each other and are parallel to a distal direction;
a door hingedly coupled to the case and adjustable between an open position and a closed position; and
a linkage that couples the door to the case.
