Abstract
A medical delivery device is disclosed that includes a rod element, a dosage member and a lock mechanism. A stem of the rod element extends into an interior of a chamber body of the dosage member and a delivery orifice of the dosage member is arranged adjacent to a proximal end of the stem of the rod element. In a dosing status, the rod element is movable relative to the delivery orifice of the dosage member, such that a dosage chamber is formed within the chamber body between the stem of the rod element and the delivery orifice, wherein the dosage chamber increases when the rod element moves away from the delivery orifice. The lock mechanism changes the medical delivery device from a lock status to the dosing status, wherein in the lock status the rod element is prevented from moving relative to the dosage member delivery orifice.
