Abstract
A safety syringe for a vacuum specimen tube having a stopper. The syringe includes a shroud with a double ended needle and a sheath slidably positioned over the needle's external end. The sheath's tip can be hypodermically inserted with the needle. The sheath moves between an exposed position where the sharp point of the needle's external end is exposed and a covered position where the sharp point of the needle's external end is inside the sheath. After the needle and sheath are inserted into the patient, the vacuum tube is seated in the shroud, piercing the stopper with needle's internal end and allowing blood to flow into the tube. As the tube is seated, it will also preferably engage an arm extending from the sheath to advance the sheath into the covered position. Thus, the sheath is in the covered position before the syringe is removed from the patient.
