Abstract
A needle hub for a drug delivery device includes a hub body, an activation button, a needle holder and a needle attached to the needle holder, a cannula holder and a cannula attached to the catheter holder, a needle actuation mechanism configured to move the needle holder and the cannula holder from a retracted position to an insertion position and configured to move the needle holder back to the retracted position, and a cannula spring biasing the catheter holder to a retracted position. Movement of the activation button is configured to cause the needle holder and the catheter holder to move from the retracted position to the insertion position, with the needle holder configured to return to the retracted position while the catheter holder remains in the insertion position.
