摘要：
The invention refers to a handheld injection device comprising a housing (10 410), a dose indicator (90 480) positioned within and axially constrained to the housing (10 410) and rotatable with respect to the housing (10 410) during dose setting and during dose dispensing, a gauge element (80 490), which is at least partly interposed between the housing (10 410) and the dose indicator (90 480), wherein the gauge element (80 490) is axially guided within the housing (10 410) and in threaded engagement with the dose indicator (90 480) such that rotation of the dose indicator (90 480) causes an axial displacement of the gauge element (80 490). A contrast element having a first marking is provided and at least a region of the gauge element (80 490) is provided with a second marking, with the first marking and/or the second marking being visible through a first window (12a) or aperture in the housing (10 410) depending on the axial position of the gauge element (80 490) within the housing (10 410).
