Abstract: A medical delivery device is disclosed having a rod element and a dosage member. The rod element has a stem and a first thread arrangement. The dosage member includes a delivery orifice, a chamber body and a second thread arrangement. The stem of the rod element extends within the chamber body and the delivery orifice is arranged adjacent to a proximal end of the stem. The dosage chamber is formed within the chamber body between the stem and the delivery orifice such that the dosage chamber increases when the rod element moves away from the delivery orifice. In a dosing status, the first thread arrangement of the rod element engages the second thread arrangement of the dosage member such that the rod element is moveable along its longitudinal axis relative to the delivery orifice of the dosage member.
