    摘要: A drive unit for a medicament delivery device is presented having an elongated plunger rod extending in a longitudinal direction, a drive force element capable of applying a drive force on the elongated plunger rod, and an actuator operably connected to the elongated plunger rod for releasably holding the elongated plunger rod in an energized state when the drive force element is exerting a drive force on the elongated plunger rod. An activator is operably connected to the actuator for releasably holding the actuator in a holding position where the actuator is designed to be movable from the holding position in a direction generally transversal to the longitudinal direction upon a displacement of the activator for releasing the plunger rod.

    摘要: An auto-injector for administering a dose of a liquid medicament includes an elongate housing arranged to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament, the housing having a distal end and a proximal end with an orifice intended to be applied against an injection site. The syringe is slidably arranged with respect to the housing. A spring capable of, upon activation: pushing the needle from a covered position inside the housing into an advanced position through the orifice and past the proximal end (P), operating the syringe to supply the dose of medicament (M), and retracting the syringe with the needle into the covered position. After delivering the medicament, an activator arranged to lock the spring in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring for injection.

    摘要: An injection device with a feedback mechanism includes a housing for a medicament container having a stopper, a plunger rod for acting on the stopper, a button interactively connected to the plunger rod, an activation member having a flexible locking device releasably connected to the plunger rod, a drive force device, a locking member slidable between positions in which the locking member either completely or partially surrounds the flexible locking device, and a guide rod. Audible and tactile information that an injection has started is provided by the plunger rod's hitting the stopper.
