|Title:||Automatic injection device with a top release mechanism|
|Abstract:||The present invention relates to a handheld mechanical injection device by which set doses of a liquid medicament can be injected from a medical reservoir. The medicament is expelled through an injection needle by release of a power reservoir in the device, the power reservoir being fully or partially released by actuation of a user operable release member being positioned at or near an upper end of the injection device, the upper end being that end of the injection device which is opposite the injection needle.|

|Assignee:||Novo Nordisk A/S (Bagsvaerd, DK)|
1. A handheld injection device, comprising: a rotatable dose setting member that is rotatable about a longitudinal axis of a housing of the injection device; a power
reservoir, comprising a torsion spring for storing energy to expel a dose from the injection device; a piston rod; a release member, located at the most proximal portion of the device, opposite an end of the device wherein a needle may be mounted; the
injection device, further comprising a rotatably arranged multi-component driver (36, 37, 38) having at least a part (38) that at least partly engages with at least part of a drive track of an associated piston rod, and a further part (36) being axially
movable into a position disconnected from the housing thus releasing energy accumulated in the power reservoir, the further part (36) being axially movable by the user applying a force onto a generally planar surface of the release member, wherein the
generally planar surface is generally perpendicular to a longitudinal direction of the piston rod in the device.
2. An injection device comprising: a housing; a drive member; a piston rod having a longitudinal direction; a torsion spring for storing energy to drive a dose from the injection device; a drive mechanism converting relative rotational motion into axial movement of the piston rod; a release button located at the most proximal end of the device, opposite an end of the device wherein a needle may be mounted, the release button having a generally planar surface that is generally perpendicular to the longitudinal direction of the piston rod.
