Invention and Early Use

In the 1980s, a hypodermic needle known as the butterfly needle was developed to provide quicker and safer intravenous injections and blood draws. This type of medical device is particularly beneficial for patients with thin or delicate veins which may be more prone to rolling during insertion using traditional straight needles.

Enhanced angling accuracy achieved by gripping near its end, using the thumb and index finger, empowers healthcare professionals to insert the needle at a 45-degree angle optimally. This ensures an adequate flow rate while minimizing potential risks associated with complications from venipuncture.

Evolution of the Butterfly Needle

The butterfly needle has seen steady improvements in design and material since its creation. The needles are now equipped with a slide-and-lock safety device, to avoid any accidental needlesticks.

Research regarding the selection of gauges for these needles has led medical professionals to lean towards using 23 gauge ones, as they cause minimal harm to blood cells but still provide accurate results from blood samples taken through them. These features make it easier and more comfortable for patients when used by healthcare workers. This is why butterfly needles remain such an important tool in medicine today.

Butterfly Needle Components and Design

The butterfly needle is widely regarded by healthcare professionals and patients alike for its high efficacy, adaptability, and unique design. Its construction includes a thin needle flanked with two pliable wings at one end and connected to flexible transparent tubing on the other side through an adapter. All of these components come together to facilitate successful blood draws as well as intravenous (IV) procedures.

Wings offer exceptional control during near-vein insertion, providing stability and visibility for accurate piercing. This design ensures quick, trauma-free collection or fluid transfer into veins, preventing the risk of air bubbles that could impede IV therapy. The device stands out as a safe access point for both collection and medical infusion therapies.

Summarily, every component of the butterfly needle has been carefully designed, from slender needles for precise incisions to wings providing a secure grip. Additional tubing allows for a clear view of vital fluids being drawn into sample containers. The synergy created by each component elevates the entire process smoothly, making the winged infusion set, commonly known as “butterfly,” a must-have tool universally preferred not only among healthcare professionals but also within the patient community.

Wings and Stabilization

The plastic wings at the base of a butterfly needle provide stability and control during insertion for blood collection. This ease of handling allows phlebotomists to perform accurate, shallow-angle insertions which is necessary when attempting venipuncture in very shallow veins or on pediatric patients.

Due to its winged design, rolling veins are prevented from occurring as well, making it an ideal choice for accessing hard-to-reach areas that require using the scalp vein set too.

Tubing and Connection

The tubing is a critical component in a butterfly needle, ensuring fluid connection to blood collection devices or intravenous (IV) lines. Crafted from plastic, these tubes can be secured onto IVs with hub connectors and are held by tube holders, locked with Luer locks for linkage to other blood extraction tools.

The transparent design provides medical professionals with a clear view of the transfusion process, especially useful when dealing with small veins or conducting challenging procedures involving needles on patients.

Needle Gauge Sizes

Butterfly needles come in a variety of gauge sizes, Ranging from 18 to 27. The number determines the needle bore diameter. Larger numbers indicate narrower diameters. This gives healthcare practitioners more flexibility when selecting suitable items for their patients or particular medical applications.

Butterfly needles typically range from 21 to 23 gauge, with smaller gauges (25G and 27G) being unsuitable for testing purposes as they may cause blood samples to clot. This variety in gauge sizes ensures that these tools can efficiently accommodate different patient needs and treatments, allowing for adequate selection based on specific requirements and procedures.

Advancements in Butterfly Needle Applications

As a result of persistent development and design improvements, butterfly needles are now an integral piece of equipment in the healthcare industry. Their use has extended beyond blood collection to administering medication and providing intravenous infusions – making them invaluable for meeting patients’ needs in multiple medical procedures. Features such as material selection safety have been improved upon over time to make these tools more reliable for fluid delivery.

In essence, butterfly needles allow healthcare professionals quick access to different components needed from one single device – increasing efficiency when caring for their patient’s health concerns.

Intravenous Infusions

Butterfly needles have become increasingly popular for IV infusions due to their design and convenience. These small, shallow-angle needles are able to easily access superficial veins, making them the ideal choice for shorter treatments as well as patients with difficult-to-reach veins.
