Disclosed is a combination of an infusion set consisting of infusion tubing and needle connected to a drug cartridge, the latter comprising a cylindrical body of inner diameter and having an open rear end, wherein a stopper is slidably disposed within the body. In an initial state after the cartridge has been filled, the stopper is partially disposed within the body such that the stopper protrudes from the rear end of the body by a distance. Pushing the stopper into the cartridge by said distance, i.e. until the stopper is flush with the rear end, displaces a predetermined volume according to E, B and the cylindrical geometry of the cartridge, which is large enough to effect complete air priming of the cartridge, infusion tubing and infusion needle.
