Abstract
A medical delivery device is disclosed having a rod element with a stem and a first thread arrangement, a dial shell with a second thread arrangement, a delivery orifice, and a switching mechanism. In a dosing status, the rod element is movable relative to the delivery orifice by rotating the dial shell around the stem causing the first thread arrangement and the second thread arrangement to travel along each other, a dosage chamber is formed between the rod element and the delivery orifice when the rod element moves away from the delivery orifice, and the rod element is prevented from movement along a longitudinal axis when an axial force is applied. In a delivery status, the rod element is movable along the longitudinal axis relative to the delivery orifice when an axial force is applied and moving the rod element by rotating the dial shell around the stem is prevented.
