Winged infusion sets are small, with a short needle and flexible wings that give you a steady, shallow puncture. Because of their shape, they’re commonly called a butterfly. They’re also used to access scalp veins, especially in infants, which is why they’re described as a scalp vein set. And they’re a standard tool in phlebotomy for drawing blood due to the control and comfort they offer. Since each of these descriptions is accurate, “all of the above” best describes the winged infusion set.
