Abstract
The present invention concerns a medical injection device for apportioning set doses of a preservative containing liquid drug. The injection device comprises a housing supporting a cartridge containing the preservative containing liquid drug and a needle cannula for transferring the liquid drug from the cartridge and through the skin of a user. Further, a needle shield which is axially movable in relation to the housing is also present. The axially movable shield carries a cleaning reservoir for cleaning at least the tip of the needle cannula between subsequent injections and the cleaning reservoir is preferably filled with preservative containing liquid drug directly from the cartridge upon initiation of the injection device. In order to eliminate any overpressure being built up inside the cleaning reservoir during the filling process, the cleaning reservoir is provided with an outlet configured to be permanently sealed by a user activated operation.
