Blood Collection Needles

Blood Collection Needles

Blood collection needles are designed to be used with blood tube holders for collecting specimens in evacuated tubes or blood culture media bottles. When drawing blood from a patient, the phlebotomist attaches the needle to a holder — one end of the needle is inserted into the patient’s vein and the other end is injected into the tube stopper to access the vacuum.

Blood collection needles are intended to be used only once, and they are designed for collecting single or multiple tubes of blood. Most have a rubber sheath over the back of the needle to prevent blood from flowing into the holder during tube changes.

Find blood draw needles in your choice of style, gauge, and length.

Needle Types

Blood collection needles have beveled tips and are typically available in 20, 21, and 22 gauges and 1 to 1.5 inches. They are sterile and sealed with a paper tab to indicate prior use or tampering.

Blood collection needles may be pre-attached to blood tube holders. These are typically packaged as sterile and used in situations where space and access are limited.

Many blood draw needles are also equipped with safety devices. Passive or active needle covers and caps can help protect the user against accidental needlesticks. Some needles can be retracted entirely into the hub after use to prevent unwanted punctures.

Winged Blood Draw Needles

Winged collection sets with integral needles and a length of tubing are also used to collect blood specimens. These can be especially helpful when a patient’s veins are fragile, it’s hard to access the patient’s veins with a straight needle, or patients have difficulty staying still or immobile during the draw.

The “wings” refer to flexible plastic pieces attached to either side of the needle base. They are pinched together and used to help position the needle for insertion. After the needle is in place, the wings lay flat against the skin and can be taped in place. Winged collection sets are available with and without pre-attached blood tube holders, with different sizes and lengths of needles, and a choice of tubing lengths.
