Abstract: A disposable pen needle, comprising a hub having a needle situated thereon having a patient end and a non-patient end, a removable patient end cap attached at the distal end of the hub, a removable non-patient end cap attached at the proximal end of the hub, wherein greater force is required to detach the patient end cap than is required to detach the non-patient end cap.

Abstract: A pen needle, comprising a reusable adapter configured for attachment to a distal end of a medication pen, the adapter having a proximal needle for accessing the interior of the pen injector and a fitting on the distal side for mating with a patient end needle assembly, and a disposable patient-end needle assembly having a base configured for mating with the fitting on the distal side of the adapter and a patient-end needle extending from a distal end of the base.

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.

Abstract: A pen needle hub and cover for a pen needle assembly that provides tactile and/or audible indicia of proper attachment between the hub of the pen needle and the pen is provided. Such indicia substantially prevent under- and over-torquing of the pen needle. The tactile indicia may include a user sensing a wave of a torque of peak value followed by a torque of lesser value.

Abstract: Pen needle packaging concepts provide sterile packaging which can be made with fewer small parts and which can be opened with one hand, streamlining the process of installing the pen needle on the medication pen. In some instances, the packaging operates as a sharps container to store the pen needle after use.

Abstract: An outer needle cover for a pen needle assembly is provided with a breakaway flange. Prior to use, the flange is connected to a body of the outer cover. The flange has a reduced cross sectional thickness portion that facilitates separation of the flange from the outer cover, thereby reducing the outer diameter of the outer cover. The reduced outer diameter of the outer cover allows the outer cover to be received by a pen cap of an existing injector device.
