Scalp Vein Set

Scalp vein sets, also known as butterfly sets, are medical devices designed for venipuncture. They feature a distinctive winged shape and are used to establish intravenous access for administering therapy or drawing blood samples from veins.

What are the types and Uses of Scalp Vein Sets?

There are 4 primary types of scalp vein sets; single wing luer lock, single wing luer slip, butterfly wing luer lock, and butterfly wing luer slip. Each variant offers something different for the specific requirements of the patient.

Venipuncture, often referred to as phlebotomy, is the medical procedure involving the incision of a vein to establish intravenous access or draw blood samples. A typical scalp vein set consists of essential components, including a hypodermic needle for vein incision, bilateral flexible wings for needle stability, a short transparent tube connecting the needle to the collection or administration system, and a connector for attaching to other devices like suction equipment or intravenous administration systems.

Selecting the Right Scalp Vein Set for your personalized use:

Small-bore scalp vein sets are typically used for children, while adults often require big-bore scalp vein sets, depending on vein size and prescribed medications. Some medications necessitate the use of big-bore sets. In phlebotomy, there's a common belief that 25G and 27G butterflies might damage blood cells and cause clotting, potentially compromising test results. However, theoretical calculations and in vitro experiments have shown this isn't accurate. Clinical trials using different butterfly sizes connected to vacuum tubes yielded similar blood cell destruction and coagulation test results, dispelling these concerns.

Care and Handling Tips for Scalp Vein Sets:

• To insert a scalp vein catheter, align it with the vein and advance it with the bevel up at a 30-degree angle until you see blood in the chamber, indicating successful vein puncture. 
• Then, lower the angle to around 10 degrees, advance the catheter into the vein, and retract the needle. Apply pressure downstream on the vein to prevent blood leakage.
• Secure the catheter with transparent film dressing and attach a syringe or IV tubing for sampling or administration.
•  Flush with saline, monitor for fluid leakage, and use gauze under the hub for comfort.
