Abstract
A method of manufacture for a drug cartridge assembly. The method includes providing a drug cartridge, providing a nozzle sub-assembly, and sterilizing the drug cartridge and nozzle sub-assembly. The method further includes assembling the drug cartridge and nozzle sub-assembly together in a configuration that enables ejection of liquid out of the drug cartridge through the nozzle sub-assembly. The method further includes filling the drug cartridge with a liquid, such as an injectable drug. The method may include separate sterilization of the drug cartridge and nozzle sub-assembly, using different sterilization processes. Portions of the method may be performed prior to sterilization within a first cleanroom, with subsequent steps being performed in a second cleanroom having a substantially lower particulate-per-volume rating than the first cleanroom.
