摘要：
In one aspect, a pen needle assembly is provided herein which includes a hub, and a needle fixed to the hub, the needle having proximal and distal ends with a lumen extending therebetween. The needle extends distally from the hub to define an exposed length between the distal end of the needle and the hub in the range of about 5.0 to 9.0 mm. The hub defines a post formed about the needle, the post having a distally-facing first skin engaging surface. The exposed length of the needle extends distally from the first skin engaging surface. The hub also defines a distally-facing second skin engaging surface which at least partially circumscribes the first skin engaging surface. The second skin engaging surface being located proximally of the first skin engaging surface. Advantageously, a pen needle assembly is provided having two skin engaging surfaces which provide stability in achieving subcutaneous injections.
