    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 translation: 笔针设置有塑料非病人端。 由于非患者端针不接触患者,所以可以形成更大直径的针头,从而更可靠地附接到药物笔,并且从药筒通过插管获得更大的药物流动。 此外,可以使用包括滚针轴承子组件和用于附接到笔体的适配器的两部分轮毂结构来降低材料体积和成本,并且减少锐利处置。 在实施例中,根据本发明的轮毂可以设置有当达到针的全部穿透深度时提供听觉和/或触觉指示的护罩。 屏蔽上的窗口可以在全穿透深度位置处露出轮毂上的色带,以向用户提供笔针已被使用的视觉指示。
