Abstract: A medical delivery system comprising a container (202) for accommodation of a medicament and a dosing assembly (204) adapted to be fastened to the container. The medical delivery system comprises a coding mechanism for ensuring that only a predetermined container can be fastened to a predetermined dosing assembly. A container for use in the medical delivery system. A dosing assembly for use in the medical delivery system.

Abstract: A dosing assembly (204) and/or a container (202) comprising fastening means (206,208) for fastening the container to the dosing assembly, the fastening means of the dosing assembly and/or the container defining an asymmetrical pattern in a plane transverse to an axial direction of the dosing assembly and/or a container.

Abstract: Disclosed is a cylindrical piston press foot mounted on a coupling element having a part with an enlarged diameter connected through a part with reduced diameter to the end of a piston rod. The device is useful in injection devices, mespecially devices by which a liquid medication is apportioned in individual doses from a cartridge.

Abstract: A dose display for a medicine administration device in which rotation of a dose setting actuator (22) is transmitted to a display means comprises a flexible disc (23) carrying numbers in a band along its perimeter, which numbers are in accordance with the set dose presented in a window in a wall of the device to show said dose. During its rotation the disc (23) is deflected to follow an inner contour of the device to attain a cylindrical shape having a generatrix extending in the axial direction of the injection device and perpendicular to the axis of rotation of the disc.
