A butterfly needle, also known as a scalp vein set or winged infusion set, is used for drips (intravenous or IV therapy).
Understanding Butterfly Needles
Butterfly needles are designed for accessing veins for either drawing blood or administering intravenous (IV) therapy. Here's a breakdown of their components:
- Thin Needle: Allows for relatively painless insertion into the vein.
- Flexible "Wings": These wings provide a grip for easy insertion and stabilization of the needle.
- Flexible Transparent Tubing: Connects the needle to the IV fluid bag or syringe.
- Connector: Attaches to the IV line or syringe.
Key Features of Butterfly Needles
| Feature | Description |
|---|---|
| Needle Gauge | Typically small, minimizing trauma to the vein. |
| Winged Design | Enables easy handling and secure placement. |
| Short Length | Suitable for superficial veins. |
Use Cases
Butterfly needles are commonly used for:
- IV Fluid Administration: Delivering fluids directly into the bloodstream.
- Medication Administration: Administering medications intravenously.
- Blood Draws: Collecting blood samples for diagnostic testing.
