What is a winged infusion set commonly used for?

A winged infusion set, often referred to as a butterfly needle, is specifically designed for venipuncture, particularly in smaller veins such as those found in the hand. This type of needle has two "wings" that provide a secure grip, allowing for better control and stability while inserting the needle into the vein. The design is ideal for drawing blood or administering medication in situations where larger needles may be inappropriate or difficult to use, like in pediatric or geriatric patients.

This is why using a winged infusion set to draw blood from a person's hand makes sense, as the smaller gauge and precise placement facilitate easier access to the often fragile veins found there. The other scenarios presented are not ideal uses for a winged infusion set. For example, drawing blood from the foot can be more complicated due to the smaller veins and potential for movement, while administering intravenous fluids typically requires a larger gauge catheter for effective fluid delivery. Inserting a catheter also requires a different type of equipment designed to create a more secure and long-term access point, such as a central line or a peripheral intravenous catheter.
