Abstract
A reloadable auto injector wherein a syringe assembly is movably positioned between a first position in which the needle is accommodated inside a housing and a second position in which the needle protrudes outside the housing. The assembly comprises a syringe, a plunger rod and a plunger rod driver 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 is configured to apply a force to the assembly thereby moving the assembly from the first position to the second position. A reload handle may be connected to the assembly so that user operation of the reload handle retracts the 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.
