A butterfly needle, also known as a blood draw butterfly, is a device that is used to access a vein to draw blood or administer medications.
A butterfly needle is also known as a "winged infusion set" or a "scalp vein set" by some medical professionals. The name comes from the fact that there are plastic "wings" on either side of a hollow needle used to access the vein. While some aspects of the butterfly needle vary, the majority have a needle enclosed in a winged sheath or plastic covering that is pulled back to reveal the needle. The needle is connected to tubing, which may be luer-locked. This is the type of connection that a syringe can be twisted onto. How is a butterfly needle used? A butterfly needle will be used by a medical professional to draw your blood or to attempt to access a vein to administer intravenous (IV) medications. They could also use an intravenous catheter. It has a retractable needle that is contained within a protective sheath. After inserting the needle into the vein, a button is pressed to retract the needle and remove the sheath or catheter. This differs from a butterfly needle, in which the needle is left in the vein rather than a plastic sheath. The butterfly needle, on the other hand, is typically shorter in length than an IV catheter. In some cases, one should be preferred over the other. One of these instances is the drawing of blood. What is the purpose that butterfly needles are used for? ●Venipuncture: A venipuncture is when a phlebotomist inserts a needle into a vein to draw blood. A phlebotomist is a doctor who specialises in drawing blood. Butterfly needles are frequently used on people who are difficult to venipuncture. ●IV Hydration: If you require IV fluids, a nurse or doctor may insert a butterfly needle into a vein. IV hydration may be used to treat dehydration or if you are unable to eat or drink due to illness or a scheduled surgery. ●Medication: A butterfly needle can also be used by a doctor to administer IV medications. These medications can be "pushed" into the body via a syringe. When you can't take medications by mouth or you need them to work quickly, getting them through a vein is a good option.
