What is the benefit of using a butterfly needle?

Using a butterfly needle is particularly beneficial because it allows for easier access in small or fragile veins. This type of needle, also known as a winged infusion set, is designed with flexible "wings" that provide better dexterity and stability during insertion. The small gauge and sharp tip of the butterfly needle enable it to penetrate delicate veins with minimal trauma, which is especially important in patients with smaller, more vulnerable veins, such as pediatrics or those with chronic illness.

The design of the butterfly needle permits better control during the venipuncture process, making it less likely to cause damage to the vein. This increased precision and sensitivity in handling allow healthcare providers to effectively draw blood or administer medication without causing undue stress to the patient's vascular system.
