Abstract:
1. An injection device, comprising: a generally elongated tubular housing having opposite proximal and distal ends; a needle shield sleeve slidably and coaxially arranged inside the housing and protruding a distance outside the proximal end of the housing; a syringe carrier mechanism, comprising a syringe carrier slidably and coaxially arranged to the needle shield sleeve, wherein the syringe carrier is configured for a syringe having a medicament and a needle; a first activator member slidably and coaxially arranged to the housing and connected to the needle shield sleeve; an actuating member slidably and coaxially arranged to the first activator member; a drive mechanism slidably and coaxially arranged to the actuating member and to the syringe carrier mechanism, wherein the drive mechanism is controlled by the actuating member; and a second activator member slidably and coaxially arranged to the distal end of the housing and fixedly connected to the actuating member; wherein the first and the second activator members are coaxially movable relative each other from a non-activation position, in which the activator members abut each other, to an activation position, in which the activator members co-act independent of a sequence in which the activator members are activated; and only in the activation position is the actuating member able to release the drive mechanism to move the syringe carrier mechanism for penetrating the needle and delivering the medicament though the needle.
