摘要

One aspect of the invention is an independent user housed in a separate cartridge of a drug reservoir in a single device operably connected to a single dispensing interface that may be operatively connected to a single activation button. There may be a drug delivery device for delivering two or more selectable multiple doses of drug. Another aspect of the present invention may be that the user-operable variable dose locking mechanism of the drug delivery device can be easily unlocked with one hand operation by the user by unlocking the lock slider.
