Abstract
A safety device for a hypodermic needle includes a hollow cylindrical portion, having an annular groove therein, disposed around the neck of a hypodermic syringe; a truncated conical surface disposed on the shoulder of the syringe; and a flexible projection abutting the neck. When a sheathed hypodermic needle engages the syringe, the safety device, via the groove therein, engages the sheath and is subsequently removed therewith. Upon recapping the needle, the conical surface shields the user from accidental puncture. Upon disengaging the sheathed needle from the syringe, the flexible projection closes behind the needle, retaining it in the sheath. Other embodiments of the invention include shields for precluding accidental needle puncture, and flexible projections for securing the needle in the sheath.
