Abstract: An injection device (1) for injecting a dose of drug, e.g. insulin for diabetes treatment, in which energy is stored in a spring member (9, 24) during dose setting. The stored energy is released and used for driving an injection mechanism during injection of a previously set dose. The injection device (1) further comprises means for electronically detecting the amount of a set dose and/or means for electronically detecting the amount of an injected dose. The electronic detecting means allows storage and/or logging of data relating to injections performed using the injection device (1).

Abstract: An injection device comprising a housing, a dose setting member being operable to set a desired dose, a piston rod adapted to cooperate with a piston to cause a set dose to be expelled, and mode locking means. The mode locking means is adapted to be in a first extreme position and in a second extreme position. When the mode locking means is in the first extreme position the piston rod is prevented from cooperating with the piston, and when the mode locking means is in the second extreme position the dose setting member is prevented from being operated to set a dose. The mode locking means is adapted to be in the first extreme position during dose setting and the second extreme position during injection of a set dose. It is ensured that the liquid drug is not inadvertently expelled during dose setting and that blood or other body fluids is not sucked into the injection device during injection. Furthermore, inadvertent changing of the set dose during injection is prevented.
