1. A medical delivery device, comprising:
a rod element having a stem with a longitudinal axis, a first thread arrangement, a distal end and a proximal end; and
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,
wherein, in a dosing status of the medical delivery device,
the rod element is movable along its longitudinal axis relative to the delivery orifice of the dosage member by the first thread arrangement of the rod element and a second thread arrangement travelling along each other, wherein 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
the dosage member comprises the second thread arrangement, wherein, in the dosing status of the medical delivery device, the first thread arrangement of the rod element engages the second thread arrangement of the dosage member.
