Unlike a straight needle, a butterfly needle is shorter and is attached to the tube that joins the tube collector or syringe and the connector. However, similar to the straight needles, they are available in several gauges, including special ones for kids. The shorter needle allows the phlebotomist to insert the needle at a shallow angle compared to the straight needle. It eases the process in several challenging and complex cases, especially while accessing fragile and small veins.
