Abstract
A pen needle (10) includes a hub (12) supporting a needle (30), an inner shield (14) enclosing the distal end of the needle, and an outer cover (16). The outer surface of the hub can include ribs (66) that cooperate with ribs (72) on the inner surface of the outer cover to assist in attaching the pen needle to a delivery device while preventing over torqueing or over tightening. In one embodiment, the inner shield (14) has a dimension to attach to the distal end of the hub (12) after use to enclose the proximal, non-patent end of the needle. In another embodiment, the outer cover (16) includes a closure member that can be removed during use and re-attached after use to cover the proximal end of the needle.
