ABSTRACT:
A safety hypodermic needle and a method of using the same are disclosed. The safety needle comprises a hypodermic needle and a protective sheath molded of an flexible polymeric material. The protective sheath comprises a needle cup which encloses the sharp needle point and is supported on a plurality of outwardly flexed ribs. The needle cup has a needle opening which is misaligned with the needle axis in the at rest or unflexed condition of the protective sheath. Application of transverse and axial forces to the needle cup aligns the needle with the opening and cause the ribs to bow outwardly so that the needle passes through the opening and into the patient's body.
