ABSTRACT:
A medical needle protector sheath which comprises a body having a top wall, side walls, an open first end, and slot formed in each side wall to receive a needle wing extending through each of the slots. The slots extend from the first end toward a second sheath end opposed to the first end, with the slots terminating in the side walls at end points which are spaced from the second end. Typically, first portions of the slots adjacent to the end points slope away from the top wall as the slots extend toward the second end. Other portions of the slots slope toward the top wall as the slots extend to the second end. Various improvements are described which result in safer-and easier use of the needle protector sheath.
