Administration device for in particular intravitreal administration of a fluid

An administration device for administration of a fluid, the administration device comprising:

• a rack for holding a container containing the fluid, and
• an actuation mechanism comprising a main unit acting on a stopper that is movably arranged within the container, a drive spring acting on the main unit, a first actuation part and a second actuation part,
• wherein the first actuation part and the second actuation part are movably attached to the rack, the first actuation part being axially secured to the rack and rotatable relative to the rack,
• further comprising at least one of the following features:
• the actuation mechanism comprises a leadscrew, wherein the first actuation part and the main unit are movably connected to one another by means of the leadscrew and wherein the first actuation part is rotatable in order to axially move the main unit and the drive spring by means of the leadscrew;
• the drive spring is at least partially releasable/expandable by actuating the first actuation part and at least partially releasable/expandable by actuating the second actuation part;
• the first actuation part can be actuated in order to move the main unit and the drive spring from an initial position to a releasing position, wherein the actuation mechanism comprises a securing element configured to prevent releasing/expansion of the drive spring during movement of the main unit and the drive spring from the initial position to the releasing position and to at least partially release/expand the drive spring when the releasing position is reached;
• or
• the second actuation part can be actuated in order to at least partially release/expand the drive spring and to move the main unit from an administration position to a final position, wherein the actuation mechanism comprises a blocking element configured to axially block the main unit both in the administration position and in the final position.
