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.
Claims15
A handheld injection device, comprising:
- a rotatable dose setting member,
- a power reservoir comprising a torsion spring for storing energy to expel a dose of medication from the injection device,
- a release member axially arranged relative to the injection device, wherein the release member forms a push button like release member,
- the injection device further comprising a multi-component driver (36, 37, 38) having at least a part (38) adapted to drive a piston rod, and a further part (36) being axial movable into a position disconnected from the housing releasing the energy accumulated in the power reservoir, the further part (36) being axially movable by the user applying a force onto the push button like release member, wherein the release member is located at the most proximal portion of the proximal end of the injection device, opposite an end of the device wherein a needle may be mounted, and
- wherein the injection device further comprises a display member adapted to display the dose to be ejected from the injection device in accordance with a setting of the dose setting member.
