Reloadable auto-injector

摘要

A reloadable auto injector is disclosed in which a syringe assembly (900) is movably positioned between a first position in which the needle (902) is accommodated inside a housing (400) and a second position in which the needle protrudes outside the housing. The syringe assembly comprises a syringe (900), a plunger rod (1500) and a plunger rod driver (1600) configured to apply a force to the plunger rod to advance the plunger rod in the syringe for delivering at least one dose of medicament. A syringe driver (1200) is configured to apply a force to the syringe assembly thereby moving the syringe assembly from the first position to the second position. A reload handle (1800) may be connected to the syringe assembly so that user operation of the reload handle retracts the syringe assembly to the first position and simultaneously reload the syringe driver to thereby ready the auto injector for delivering a further dose of medicament. The plunger rod driver is not re-activated.
