摘要： An injection device (1) for administering a fixed dose of a medication is provided. The injection device (1) comprises a housing (2) wherein a drive mechanism comprising a drive member (3) is at least partially enclosed and a dosing element (34) which is fixed relative to the drive member (3). Here, a dose can be set by rotating the dosing element (34) relative to the housing (2) in a dose set direction (105) and the dose can be dispensed by pushing the dosing element (34) towards the housing (2). Moreover, a method is provided for operating an injection device (1) for the administration of a fixed dose of a medication: A dose can be set by rotating a dosing element (34), a dose can be dispensed by pushing the dosing element (34) towards the housing (2) and a dose can be cancelled by rotating the dosing element (34) in a direction (106) opposite to the dose set direction (105).
