ABSTRACT:
A cartridge retainer assembly is provided for a medication delivery pen. The cartridge retainer assembly includes a generally tubular body for receiving, supporting and accurately positioning the body and shoulder portions of a cartridge of medication. A needle mounting collar is floatably mounted to the body of the cartridge retainer assembly for receiving the neck, rubber septum and crimped metallic sleeve of the cartridge. The needle mounting collar will float into a position which compensates for eccentricities and dimensional variations of the cartridge.
