Abstract
This invention relates to a drug cartridge assembly for use with a reusable body assembly of a medication delivery pen. The drug cartridge is disposable and is in the form of a single integral unit having a generally tubular barrel. Medication is pre-filled into the drug cartridge and is retained therein by an elastomeric stopper or plunger. The plunger is in sliding fluid-tight engagement with a tubular wall of the barrel. A proximal end of the tubular barrel is configured for interconnecting the drug cartridge with a pen body assembly and a distal end of the tubular barrel is configured to securely but releasably engage a needle cannula assembly.
