Abstract
Systems, components, and methods are disclosed for withdrawing drug from a liquid drug container and transferring drug to a medical device. One or more components may have keying features so that only the correct liquid drug container and medical device are accessed, making sure the medical device is filled with the correct drug. A syringe needle hub may have keying features corresponding to keying features on a cap on the liquid drug container and on the medical device. An alignment device facilitates easy-to-operate filling of a medical device. The alignment device aligns a liquid drug container over a fill port of the medical device and can include components for moving the liquid drug container into engagement with the medical device and for automatically initiating drug transfer to the medical device. A retractable skirt or needle cover protects the needle and is unlocked only when the skirt or needle cover is close to or touching the medical device.
