Butterfly needles are ideal for people with small or spastic (rolling) veins and can even be inserted into the tiny veins of the hand, foot, heel, or scalp.
Because of their small size (far smaller than an intravenous catheter) and shallow-angle design, butterfly needles can access superficial veins near the surface of the skin.
This not only makes them less painful to use, but allows them to access veins that are small or narrow, such as those in infants or the elderly.
Butterfly needles are ideal for people who are hesitant about needles because they are less threatening. They are also less likely to cause profuse bleeding, nerve injury, or a vein collapse once the needle is removed.
Newer models have a slide-and-lock sheath that automatically slides over the needle as it is extracted from a vein, preventing needlestick injuries and the reuse of a used needle.
