Abstract
An assembly for an injection or infusion device includes i) a cartridge being closed by a septum and the surface of the septum being sterile and covered by a first continuous flexible strip, and ii) a fluid path unit comprising a cartridge holder and a fluid path compartment comprising a needle in an interior, the needle is configured to penetrate the septum of the cartridge through a passage in the fluid path compartment. The passage is closed by a second continuous flexible strip keeping the interior of the fluid path compartment in a sterile condition. The cartridge is inserted into the cartridge holder aligning the septum with the passage and sandwiching both strips between the septum and the fluid path compartment. Both strips may be simultaneously removable from the cartridge and fluid path compartment thereby, establishing a sterile connection between the septum and the interior of the fluid path compartment.
