Abstract: A syringe shielding apparatus comprising an adapter having a tubular collar and a flexible snap ring joined by a living hinge, and a needle shield. Radially extending projections, provided on the tubular collar, slide within longitudinally extending slots in the needle shield, allowing the longitudinal extension and retraction of the needle shield relative to the housing of the syringe. The flexible snap ring expands into a groove in the needle shield at extension. Expansion of the snap ring into the groove in the needle shield locks the shield in the extended position over the syringe needle.

Abstract: A magnifying syringe shield including a hollow sleeve, a needle shield, and a snap ring. Radially extending projections, provided on the hollow sleeve, slide within longitudinally extending slots in the needle shield, allowing extension and retraction of the needle shield. The snap ring is positioned within a groove in the hollow sleeve at retraction, and extends into a groove in the needle shield at extension. Extension of the snap ring into the groove in the needle shield locks the shield in the extended position over the syringe needle. The needle shield further includes a magnifying arrangement for enlarging the dosage indicia imprinted on the housing of an enclosed syringe.
