Syringe needle safety devices have a spring-activated shield attached to a disposable syringe needle. After the venipuncture, the phlebotomist activates the device with the thumb holding the syringe, and a spring locks a protective plastic tip into place, protecting the needle. The needle then can be removed and discarded. The syringe is attached to the safety transfer device to deliver the collected blood into the appropriate Vacutainer tubes. One-handed Vacutainer needle: After the needle has been used and removed from the vein, the thumb holding the Vacutainer holder slides under the base of the pink safety device, causing it to snap over the contaminated needle. Butterfly needle safety lock: After the venipuncture, the dominant hand holds the butterfly tail while the nondominant hand pulls back on the tubing, causing the needle to slide into the tubing and lock into place. Needle blunting butterfly set: A third "wing" is rotated after collection and before removal of the needle from the vein. As the third wing is rotated, it moves the blunt needle down the shaft before it is removed from the patient.
