摘要：
The invention refers to an injection device comprising a housing (10), containing a cartridge (170) with an amount of liquid to be dispensed, a drive sleeve (41), which is rotationally constrained to the housing (10) during dose setting and spring driven rotatable relative to the housing (10) during dose dispensing, a dose dial member (60) for setting a dose to be dispensed, which is rotatable relative to the housing (10) during dose setting and during dose dispensing, and which is rotationally coupled to the drive sleeve (41) during dose dispensing. The device further comprises a last dose protection mechanism (41, 50, 60) for preventing the setting of a dose, which exceeds the amount of liquid left in the cartridge (170), with a limiter (50), which is interposed between the drive sleeve (41) and the dose dial member (60). Further, the device comprises two different display members (110, 120), each indicating the set dose.
