Patent ID: 8708975

Claim:
A syringe comprising a barrel having a distal portion, a proximal portion and an interior defined by side walls to directly hold a medicament, where the proximal portion of the barrel has a finger flange; a needle fixed to the distal portion of the barrel; a plunger seal slidably positioned within and in direct contact with the side walls of the barrel interior; a plunger fixed to the plunger seal where a portion of the plunger extends proximally outside of the barrel interior; a first coding feature located on the barrel for mechanical engagement with a second coding feature of an auto-injector device configured to effect penetration of the needle into skin and to then dispense the medicament, where the syringe is configured to operate manually as a stand alone injection device by engaging the finger flange and plunger with fingers on one hand and pushing the plunger distally after needle insertion into skin, and wherein the first coding feature is designed such that the syringe is mountable in an auto-injector device having a second coding feature only if the first and second coding features match and where the first coding feature is configured such that the syringe may not be forced into a non-mating auto-injector.
