Butterfly Needles Explained A butterfly needle, also known as a scalp vein set or a winged infusion set, is a device specialized for venipuncture. It is used to access a superficial vein for phlebotomy or IV injections. Unlike a straight needle, a butterfly needle is less painful and is easier to use, because of the winged tubing that allows for greater flexibility, when dealing with difficult veins or those that are hard to see and feel. The size of butterfly needles ranges from 18 to 27 gauge bore. The higher the number, the thinner the needle gets. This is why 21G and 23G are the most common, while 25G and 27G are mostly avoided, because it is believed to clot or hemolyze the blood samples, making them invalid for blood tests. Types of Butterfly Needles Standard safety device ; This type of needle has been the industry standard for many years. Two of its most common sizes are 21G and 23G. A standard safety unit consists of a needle, tubing, and a sheathed needle attached to a hub that will be used in the evacuated tube system.
