Abstract: A manually operated needle-shielding safety device attachable to a standard hypodermic needle and syringe medical apparatus (42). By forward directed thumb or finger stroke upon a proximally projecting pushrod (128) slidably operable within a pushrod channel (82) positioned parallel to and radially removed from the primary syringe barrel plunger (44), the elongated shield (148) is pushed from a housing (66) mounted at the base of the hypodermic needle and syringe apparatus (42), rotated longitudinally from an inverted position, and advanced to the distal end of the syringe apparatus (42) against resistance from a rubber band (64) or integral expansion spring (244). The distal portion of the shield (148) surmounts the tip of the needle (54) and the needle (54) enters the shield (148) laterally through an opening in the shield face (154).
