DRIVE MECHANISM OF A DRUG DELIVERY DEVICE |
| 摘要 |
The present invention relates to a drive member of a drug delivery device for dispensing of a dose of a medicament, the mechanism comprising: a housing (30) extending in an axial direction (1, 2), a piston rod (90) to operably engage with a piston (16) of a cartridge (14) to displace the piston (16) in an axial distal direction (1), a dose indicating mechanism (130) comprising a first spool (140; 240) and a second spool (142; 242) rotatably supported in the housing (30), wherein first and second spools (140, 142; 240, 242) are oriented substantially parallel to each other and substantially parallel to the piston rod (90), a dose indicating tape (146; 246) coiled onto at least the second spool (142; 242) and fixed with an end to an outer circumference of the first spool (140; 240). |
