Closed system blood collection vacutainer needles, also known as vacuum blood collection needles or vacutainer needles, are medical devices used to collect a blood sample from a vein.

The vacutainer needle is designed to be used in conjunction with a vacutainer, a system of vacuum-sealed tubes that stabilizes blood and prevents coagulation.

Vacutainer needles are inserted into a vein and the vacuum in the vacuum tube draws the blood into the tube. After the desired amount of blood is drawn, the vacutainer needle is removed and the vacutainer is sealed ready for transport to the laboratory for analysis.
