Abstract
A hypodermic syringe provided with a safety hypodermic needle and shield assembly to obviate the danger of a handler thereof being accidentally pricked by the point of the needle after it has been injected in a patient and then withdrawn, the withdrawn needle possibly being contaminated with infectious microorganisms. The assembly includes a needle-supporting hub receivable in a socket formed at the front end of a fluid chamber in a standard syringe provided with a projecting nozzle which is inserted in the hollow base of the hub to communicate with the needle. Anchored on top of the hub which serves as a pedestal therefor and surrounding the needle is a helical spring, the convolutions in the upper section of the spring forming a cone and terminating in a sheild through whose center passes the axis of the helix. The normal length of the spring is such as to place the shield in the protective mode of the assembly in front of the needle point to prevent human contact therewith.
