<p>A pen needle assembly having a hub (151) with an increased surface area that contacts a patient's skin is provided. The increased contact area at the distal end (158) of protrusion (155) extending from the body of the hub with the patient's skin during injection of a cannula decreases the pressure exerted against the patient's skin, thereby increasing the comfort of the patient. A bonding adhesive is disposed on an outer surface of the hub, thereby decreasing the required curing time of the adhesive. Additionally, the increased contact area, between the cannula adhesive and hub increases the strength of the bond therebetween.</p> |
