DOSE SETTING MECHANISM FOR PRIMING A DRUG DELIVERY DEVICE

摘要

A method and system for priming a drug delivery device. The drug delivery device includes a dose dial sleeve and an internal housing portion. The dose dial sleeve is coupled to the internal housing. The dose dial sleeve rotates on a substantially circumferential rotational path during priming of the drug delivery device. Further, the dose dial sleeve rotates on a helical path during dose setting of the drug delivery device.
