1. A medical delivery device, comprising:
a rod element having a stem with a longitudinal axis, a distal end and a proximal end;
a dosage member comprising a delivery orifice and a chamber body with a distal end, a proximal end and a hollow interior, wherein the stem of the rod element extends into the interior of the chamber body of the dosage member and the delivery orifice is arranged adjacent to the proximal end of the stem of the rod element; and
a lock mechanism for changing the medical delivery device from a lock status to a dosing status, wherein
in the dosing status of the medical delivery device, the lock mechanism is disengaged whereby the rod element is movable along its longitudinal axis relative to the delivery orifice of the dosage member, such that a dosage chamber is formed in the interior of the chamber body of the dosage member between the stem of the rod element and the delivery orifice which dosage chamber increases when the rod element moves away from the delivery orifice, and
in the lock status of the medical delivery device, the lock mechanism is engaged to thereby prevent movement of the rod element along its longitudinal axis relative to the delivery orifice of the dosage member.
