Embodiment Construction

[0112] figure 1 A drug delivery device 1 for delivering a premixed medicament contained in a cartridge 2 is shown. The premixed drug comprises a first drug A such as insulin and a second drug B such as GLP-1 which is mixed into the drug solution A. The drug delivery device 1 comprises a sleeve-like body 3 acting as a housing. The drug delivery device 1 extends from a proximal end 4 to a distal end 5 . At the proximal end 4, the dial handle 6 is rotatably connected during dose setting to a dose dial part 7, wherein the dose dial part 7 is configured as a number sleeve and has a plurality of dose numbers 8 printed on its peripheral surface . The dose dial member 7 is threadedly engaged with the body 3 and has on its outer surface a helically extending groove 9 which engages a correspondingly formed thread (not shown) on the inner surface of the body 3 so that when the dose is When the dial member 7 is rotated in a first direction by rotating the dial 6 during dose setting, t...
