The present invention relates to a medicament delivery device comprising a housing, a biased medicament delivery member guard arranged movable in relation to the housing from a proximally extended position to a retracted position, a power pack comprising a plunger rod and a force element arranged to act on said plunger rod, which power pack is actuated by a release clip movable in relation to the housing and arranged to said plunger rod for releasably holding said plunger rod with the force element in a tensioned state; a rotator rotatably arranged inside said housing, which rotator is arranged with a guide element and a medicament delivery member guard lock element on its outer surface, wherein said medicament delivery member guard is arranged with release clip activation elements operably arranged to act on said release clip for releasing said plunger rod, and wherein said medicament delivery member guard is further arranged with a rotator activator element arranged to cooperate with said guide element for turning said rotator, upon movement of said medicament delivery member guard to the retracted position, and wherein, upon movement of said medicament delivery member guard back to the extended position, said rotator activator element will engage said medicament delivery member guard lock element and lock said medicament delivery member guard in a shielding position after removal of said medicament delivery device from a medicament delivery site.

Devices and methods for a compact injector are provided with a compact configuration for ease of carrying or storage, and an activated configuration ready for injection. In the compact configuration, a plunger and a needle are both retracted into the injector housing, and upon actuation to the activated configuration, the plunger extends proximally and the needle extends distally, ready for injection. An extendable needle shield is also provided to block visibility of the needle during injection, and to reduce the risk of inadvertent needle stick at other times, including disposal.

The injection needle removal device has: a cylindrical outer cylinder on an upper opening of an injection needle case; a helical track on an inner peripheral surface of the outer cylinder in a helical shape from an upper locking point to a lower locking point; a syringe holding cylinder helically advances in the outer cylinder along the helical track; an injection needle tightening ring on a lower end portion of the syringe holding cylinder, the injection needle tightening ring holds an injection needle base portion of a syringe in the syringe holding cylinder to clamp the injection needle base portion; and a locking mechanism that stops the syringe holding cylinder where the injection needle tightening ring is exposed from a lower side of the outer cylinder at the lower locking point. The injection needle tightening ring turns to remove the syringe needle base portion from the syringe body and to expand in a distal-end divided manner by a turning generated by a descending movement of the syringe holding cylinder proximate the lower locking point to discard the injection needle base portion into the injection needle accommodation case with the injection needle.
