摘要：
A needle hub (10) 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 (26) forming a first contact surface with a surface area of about 1-5 mm2 and an outer ring (28) at a peripheral edge forming a second contact surface with a combined surface area of about 15 to 50 mm2.
