Flange extender for use with an injection device and method of assembly

摘要

A flange extender (200) for use with an injection device (100) is described. The flange extender includes first (202) and second (204) flange extender pieces and a locking mechanism (216, 218, 220, 222) to lock the first and second flange extender pieces to one another. In one embodiment, the locking mechanism includes each piece having a locking finger extending from the piece and an aperture adapted to receive the locking finger. The first and second flange extender pieces extend in a direction transverse to a main axis of the injection device to thereby provide a surface area for manual manipulation of the injection device during an injection. The first and second flange extender pieces also attach to each other on opposite sides of the injection device.
