Abstract
A needle-bearing hub for a pen needle is provided with a distal patient-facing side having an enlarged surface for contact with the subject's skin. The enlarged surface is provided with a radius of curvature that increases the likelihood that the needle reaches full injection depth when an injection is performed at an inclined angle with respect to the surface of the skin and with to the desired depth less discomfort to the patient.
