摘要：
The present invention relates to an injection apparatus in which a cartridge has a distal end sealed by a pierceable flexible septum abutting a pressure element. Further a shielded needle cannula penetrates the distal septum. This pressure element is axially movable whenever the shield is axially moved such that the volume of cartridge decreases. A motion transforming means transforms axial movement of the shield into axial movement of the pressure element via a rotational movement of the motion transforming means.
