Abstract

The invention relates to an auto injector, by which a fixed dose of a medicament can be injected as self-treatment, and by which needle exposure to an accessible position, injection of the medicament and retraction of the needle to an inaccessible position is automatically performed as a continuous sequence, after the auto injector is triggered. The functional sequences of the device are driven by a torsion spring (14) and controlled by thread engagements between a driver (7), a housing (2) and a syringe assembly (1). At the end of injecting the medicament, a thread engagement between the driver (7) and the housing (2) disengages, allowing the driver (7) and the syringe assembly (1) to retract the needle by means of a second spring (13).
