Abstract
An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection.
