A needle hub () for a pen needle is provided with an enlarged surface for contact with the skin of a patient. The enlarged surface is provided with a surface having a dimension and shape to enable a needle or cannula to penetrate the skin to a desired depth and permit substantially the entire exposed length of the needle or cannula to penetrate the skin to the desired depth. The surface of the needle hub can be formed by an inner cone shaped member () forming a first contact surface with a surface area of about 1-5 mmand an outer ring () at a peripheral edge forming a second contact surface with a combined surface area of about 15 to 50 mm.

Pen needle hub injection depth optimization

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.
