Abstract
A medication delivery pen having a vial retainer with a side opening have flexible snap wings that spread to receive and retain a standard or threaded vial within the vial retainer. The vial retainer also includes an improved means of attaching the vial retainer to a pen injector body, using a cam and cam follower design together with a ratcheting mechanism to prevent removal of the vial from the medication delivery pen. Alternatively, a release mechanism could be used so that the vial may be removed from the medication delivery pen. In addition, the vial retainer includes an opening for receiving the vial defined by a pair of flexible snap wings.
