1.Product Description
A butterfly needle, also known as a winged infusion set or scalp vein set, is a medical device used for venipuncture procedures. A butterfly needle is a shorter needle with a thinner gauge, ranging from sizes 18 to 27. When measuring gauges, the higher the number, the thinner the diameter, making butterfly needles one of the thinnest needles for phlebotomists to use. Typically, 21 or 23 gauge are used for blood draws.
2.Key Features
- Flexible Tubing: The butterfly needle features a thin, flexible tubing that allows for easy maneuverability during venipuncture.
- "Wings" Design: The needle has wings on either side that provide stability and control during insertion into the vein.
- Small Gauge Needle: Typically equipped with a smaller gauge needle compared to standard needles, reducing patient discomfort during insertion.
- Luer Adapter: Comes with a Luer adapter for easy connection to collection tubes or intravenous lines.
- Sterile Packaging: Butterfly needles are individually packaged in a sterile manner to ensure cleanliness and prevent infections.

4.Application
- Blood Draws: Butterfly needles are commonly used for drawing blood samples from patients, especially those with fragile or difficult veins. The smaller gauge needle and winged design make them suitable for obtaining blood samples with minimal trauma to the patient.
- Intravenous (IV) Access: Butterfly needles are used for short-term IV access for administering medications, fluids, or blood products. They are particularly useful when a patient requires frequent needle insertions or when continuous access to the vein is not needed.
- Pediatric and Geriatric Care: Due to their gentle insertion and smaller gauge, butterfly needles are often preferred for pediatric and geriatric patients who may have delicate veins that are challenging to access with standard needles.
- Emergency Situations: In emergency departments, butterfly needles can be used for rapid venous access when time is critical, allowing medical professionals to quickly administer medications or fluids to stabilize a patient.
- Outpatient Procedures: Butterfly needles are commonly used in outpatient settings for various medical procedures that require venipuncture, such as chemotherapy, blood transfusions, and intravenous infusions.
- Home Healthcare: In home healthcare settings, butterfly needles are used for procedures such as administering medication, intravenous therapy, or nutritional support for patients who receive healthcare services at home.
- Specialized Tests: Butterfly needles may be used for specialized tests that require precise and controlled blood collection, such as certain diagnostic tests or therapeutic monitoring.
Q&A
1.What is the difference between a butterfly needle and a regular needle?
The shorter length of the butterfly needle and the angled entry allow for easier access to narrow and delicate veins and veins located in parts that are difficult to reach with a straight needle. Selecting the right needle is a significant driving factor in successful, effective, precise, safe blood collection.
2.How painful is a butterfly needle?
Since butterfly needles are often less painful than straight needles, you may encounter patients who specifically ask you to use a butterfly needle. What's important is that you use the proper gauge to get the job done effectively, quickly, and, most importantly, as pain-free as possible.
3.Are butterfly needles safer?
Pros of Higher Butterfly Needle Gauges
Produces a smaller puncture wound: A smaller needle size with a higher gauge makes a tinier puncture wound. This means less bleeding, particularly for patients with disorders such as hemophilia, and a lower risk of infection.
