Scalp Vein Set

A scalp vein set, also known as a butterfly needle or winged infusion set, is a specialized medical device used for venipuncture, which involves accessing a superficial vein or artery for intravenous (IV) injections, blood draws (phlebotomy), or administering IV fluids or medications. It gets its name from the two soft, flexible, bilateral “wings” attached on either side of the needle, resembling a butterfly. These wings facilitate easy handling and attachment to the skin, helping to stabilize the device during insertion.

Components

The main components of a scalp vein set include:

• Hypodermic Needle: A thin, short, beveled, siliconized needle designed to minimize tissue damage and reduce the risk of infection.
• Wings: Two flexible plastic tabs, resembling butterfly wings, that allow for easy placement and stability during use.
• Flexible Tubing: A transparent tube, typically 20-35 cm long, that connects the needle to a connector. The tubing is soft, non-toxic, and non-irritant, preventing kinking or coiling during use.
• Connector: A female Luer lock or slip fitting at the proximal end of the tubing, allowing for a firm and stable connection to other devices like syringes, vacuum tube holders, or extension tubing from an infusion pump or IV bag.

Types and Variations:

Scalp vein sets are available in various types and models, says Medikabazaar. Options include standard and safety sets, with safety sets featuring mechanisms to prevent needle-stick injuries. They come with different wing sizes, tubing lengths, and gauge sizes to suit various needs. Gauges range from 18G-27G, with smaller gauges for delicate veins and larger gauges for higher flow. Some sets have a single wing, while others have the typical two butterfly wings.

Scalp vein sets are commonly used for:

• Venipuncture (drawing blood).
• Administering IV fluids, medications, and blood products.
• Providing care for infants, children, and the elderly who have small or fragile veins.
• Oncology treatments.
• Patients with bleeding disorders.
• Certain plastic surgery procedures, such as saline infusion and drainage.

Benefits

Advantages of scalp vein sets include improved reach and flexibility, suitability for superficial and hard-to-access veins, potential reduction in blood cell breakdown during blood draws, lower risk of complications, and being less painful.

Precautions

Key precautions include using the device only once to prevent infection, ensuring it is sterile and the packaging is intact before use, using it under the supervision of a healthcare professional, and disposing of it properly in sharps containers.

In summary, scalp vein sets are valuable medical devices offering a safer, more comfortable, and precise way to access veins, particularly in vulnerable patients and challenging areas.
