Abstract
A hypodermic needle assembly is described which automatically covers the pointed end of the needle after the assembly is used in order to prevent accidental punctures. A sheath circumscribes the needle and is held a patient's tissue to allow sliding movement of the sheath over the needle pointed end, and preferably locking of the needle within the sheath, as well, when the needle is withdrawn from the patient.
