Abstract:
An injection device, in some embodiments an autoinjector, which includes a thrust spring that advances an injection needle from an initial position to an insertion position from the distal end of the injection device and that causes a product to be emptied from the product reservoir by an emptying movement, and a return spring that retracts the injection needle from the insertion position into the distal end of the injection device counter to the force of the thrust spring, wherein the return spring is decoupled from the thrust spring during the emptying movement.
