Abstract:
1. A collection comprising a plurality of cartridge assemblies each having one or more coded fasteners for connecting different medicaments to specifically matched dose setting members of the collection to make up a family of delivery devices, the collection comprising: two or more cartridge assemblies, where a first cartridge assembly comprises, a) a first medicament; and b) a fastener comprising a first coding feature that is unique to the first medicament and is specifically coded to engage a complementary coding feature on a fastener on a first dose setting member that is configured to dispense the first medicament, wherein the first coding feature is different than a second coding feature on a fastener on a second cartridge assembly in the collection that contains a second medicament, where the first and second medicaments are different and where the second cartridge assembly will not operably connect to the first dose setting member, thereby preventing the first dose setting member from administering the second medicament, wherein each fastener in the collection of cartridge assemblies is coded by a position of the fastener relative to a detent, where the detent is configured as a protrusion that snaps over a corresponding detent of the fasteners on the dose setting members into a locking position when rotated relative to the fasteners on the dose setting members to operably connect a cartridge assembly to a dose setting member.
