What is a ‘butterfly’ needle, and when is it commonly used?

A ‘butterfly’ needle refers to a winged infusion set that has two ‘wings’ on either side of the needle hub, allowing for better control and stability during venipuncture. This design makes it particularly useful for drawing blood from small or difficult veins that can be challenging to access with standard straight needles. The wings provide the phlebotomist with leverage, allowing for a steadier hand, which is especially beneficial when dealing with shallow veins, especially in pediatric patients or those with compromised venous access.

This type of needle is commonly employed in scenarios where precision and the ability to maintain a secure hold over the needle are critical, as small veins can collapse easily if not handled correctly. The use of a butterfly needle minimizes discomfort for the patient and helps to ensure a successful draw.
