Patent attributes
An autoinjector includes a case configured to receive a 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 a 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 plunger, and 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.
