Abstract
A medical delivery device is disclosed having a rod element having a first thread arrangement, a dosage member having a second thread arrangement, a dial unit, and a coupling structure coupling the dial unit to the dosage member. A stem of the rod element extends into a chamber body of the dosage member. In a dosing status, the rod element is movable relative to the dosage member by the first and second thread arrangements travelling along each other such that a volume of a dosage chamber of the chamber body is varied. In the dosing status rotation of the dial unit applies a torsional force to the dosage member, wherein the torsional force rotates the dosage member such that the first and second thread arrangements travel along each other. An overload protection mechanism is provided that is configured to prevent the torsional force from exceeding a predefined threshold force.
