A safety syringeincludes a generally tubular bodyhaving a needle endand plunger end, needleand retractable needle seat, two-way valve, plunger, stopper, piston, and rear plunger seal. During use, the plunger may be moved to create a vacuum in the plunger. The user then moves the plunger toward the needle end, pressurizing a vial, then pulls backward to a selected position corresponding to the desired volume of fluid to be withdrawn. At the conclusion of the injection stroke, the piston is disengaged from the plunger. The vacuum within the plunger retracts the needle safely into the tubular body.

The blood sampling assembly includes a retractable double-ended needle so that a vial may be passed through an opposed end of the needle to obtain a blood sample. The assembly includes a hollow cylinder including circumferentially spaced seat tabs which allow a needle seat and the needle supported thereon to be released upon rotation of tube with respect to hollow cylinder. The extractor assembly includes a stopper for maintaining a vacuum within tube to withdraw the needle to a retracted position within the tube upon rotation of the tube, the end cap, and the stopper retainer. A stopper tab positioner rotationally connects the stopper to the cylinder.
