The butterfly needle, also known as a winged infusion set or scalp vein set, is a type of needle used for drawing blood or administering medications via a vein. It consists of a small, thin needle with two plastic or metal wings that resemble a butterfly, making it easier to handle and maneuver, especially in pediatric or geriatric patients. The design of the butterfly needle allows for a more precise and controlled insertion into the vein, reducing the risk of complications and discomfort for the patient.
Design and Construction
The butterfly needle is typically made of stainless steel or a other medical-grade materials, with a beveled tip to facilitate smooth entry into the vein. The wings or flaps on either side of the needle provide a secure grip, allowing healthcare professionals to easily rotate and maneuver the needle during insertion. The length of the needle can vary, but it is usually between 1⁄2 to 1 inch (1.3 to 2.5 cm), making it suitable for use in both superficial and deeper veins. The butterfly needle is often attached to a tube or a syringe, which is used to collect blood samples or administer medications.
Applications and Uses
The butterfly needle is commonly used in various medical settings, including hospitals, clinics, and laboratories. Its applications include drawing blood for laboratory tests, administering medications or vaccines, and providing fluids or nutrients to patients. The butterfly needle is particularly useful in situations where a standard needle may be too large or cumbersome, such as in pediatric or neonatal care. Additionally, the butterfly needle can be used for patients with fragile or delicate veins, as it is designed to cause minimal trauma to the surrounding tissue.
