Methods and devices for use and handling of intravenous and/or subcutaneous needles, and, more particularly, to safety devices for shielding needles or other sharp articles or devices that present a safety hazard are disclosed. In an embodiment, a needle protective sheath can include a top wall, a bottom wall, and a pair of side walls joining the top and bottom walls.
