Patent ID: 7118553

Claim:
An autoinjector comprising: a housing; a receptacle for an active substance, which receptacle, together with a connected injection needle, is displaceable within the housing by spring force for inserting the injection needle into a patient; a piston displaceable within the receptacle in a dose delivery direction by spring force for expelling the active substance; a transfer mechanism for transferring the spring force to at least one of the receptacle and piston; a holding mechanism for holding the transfer mechanism; a releasing mechanism for releasing the holding mechanism, wherein the releasing mechanism is enabled by moving the releasing mechanism in a direction substantially opposite to the dose delivery direction from a first position into a second position, and wherein the releasing mechanism releases the holding mechanism when it is moved in the dose delivery direction from the second position to the first position, thereby releasing the transfer mechanism; and a resetting mechanism for disengaging the releasing mechanism when the releasing mechanism is in the second position prior to delivery of the dose to enable the releasing mechanism to be moved in the dose delivery direction to the first position without releasing the holding mechanism.
