    Abstract: A pen needle is provided with a plastic non-patient end. Since the non-patient end needle does not contact the patient, the needle can be formed with a larger diameter, permitting more secure attachment to a medication pen and greater medication flow from the cartridge through the cannula. In addition, a two-part hub construction comprising a needle bearing sub assembly and an adapter for attachment to the pen body may be used to lower materials volume and costs, and reduce sharps disposal. In embodiments, a hub according to the invention may be provided with a shield that provides an audible and/or tactile indication when full penetration depth of the needle is achieved. Windows on the shield may reveal a color band on the hub at the full-penetration depth position to provide the user with a visual indication that the pen needle has been used.
