Abstract
A needle hub assembly for coupling to a pen needle delivery device includes an outer cover having a first well receiving the needle hub and inner shield covering a cannula of the needle hub. A second well is spaced from the first well and receives the inner shield. In use, the pen delivery device is coupled to the connecting end of the needle hub to withdraw the needle hub and inner shield from the first well. The inner shield is inserted into the second well where the inner shield is gripped so that the inner shield can be separated from the needle hub without the user handling the outer cover or the inner shield. After use, the needle hub is inserted into the first well and the pen needle delivery device is separated from the needle hub. The needle hub is retained within the first well where the outer cover containing the used needle hub and inner shield can be discarded as a single unit.
