Abstract
A device for delivering a dose of medicament includes a generally elongated housing, a container containing medicament to be injected through a needle, a force device acting on the container and capable of, upon activation, moving the container and the needle for penetration and subsequently expelling medicament through the needle, and an activating device arranged to activate the force means. The activating device includes a needle shield slidably arranged in relation to the housing, which upon movement releases the force device, and a release device arranged in the front, injecting, area of the device, which, when in a non-activated state prevents the needle shield from sliding, thereby preventing activation, and when activated, enables sliding of the needle shield and thereby activation of the device. The release device is arranged on the device such that it promotes an ergonomic grip of the device for its activation.
