    摘要: An injection device (10) comprises an injection solution receptacle (30) and a plunger (70) at feast a portion of which is slidably received in the injection solution receptacle (30), wherein the plunger (70) is displaceable relative to the injection solution receptacle (30) in a distal direction in order to expel an injection solution contained in the injection solution receptacle (30) from the injection solution receptacle (30). A first plunger stop mechanism (140) is adapted to stop a displacement of the plunger (70) relative to the injection solution receptacle (30) in the distal direction at a first dosing position (P1). A second plunger stop mechanism (140) is adapted to stop a displacement of the plunger (70) relative to the injection solution receptacle (30) from the first: dosing position (P1) in the distal direction at a second dosing position (P2), wherein the first and the second dosing position (P2) of the plunger (70) are selected in such a manner that the plunger (70), upon being displaced relative to the injection solution receptacle (30) between the first and the second dosing position (P2) is adapted to expel a desired dose of the injection solution contained in the injection solution receptacle (30) from the injection solution receptacle (30).

    摘要: The invention concerns an injector device (100), comprising access means (110, 115) configured to selectively allow and prevent a cartridge (120) storing a pharmaceutical product (122) from being removed from the injector device (100), a self-test unit (130) configured to cause a self-test of at least one of an electronic component and an electronic assembly of the injector device (100), and a control unit (140) configured to control the access means (110, 115) to allow the cartridge (120) to be removed from the injector device (100) in case the self-test has failed.
