Abstract
A drug reservoir loading and unloading mechanism for drug delivery device using unidirectional rotated lead screw and method thereof are disclosed. The drug reservoir loading/unloading mechanism allows exchanging the drug reservoir quickly with very few steps and with more safety. The invention neither requires rewinding of the drive system either automatically or manually while replacing the drug reservoir nor requires an additional adapter to secure the drug reservoir.
