摘要：
The present disclosure relates to a drug delivery device, comprising a housing, a cartridge, the cartridge containing a drug in a quantity sufficient for a plurality of doses of the drug, a bung, the bung being movably retained within the cartridge to dispense a dose of the drug from the cartridge upon movement of the bung with respect to the cartridge, and a drive mechanism, the drive mechanism being operable to transfer a driving force to the bung to dispense the dose of the drug from the cartridge. The drug delivery device is configured such that the maximal driving force which is transferrable to the bung via the drive mechanism varies and is adjusted to the current position of the bung within the cartridge.
