What Is a Butterfly Needle?
A butterfly needle, also known as a winged infusion set, is a specialized blood collection tool designed for drawing blood from veins that are small, fragile, or hard to access. The name comes from its unique shape — two plastic “wings” on either side of the needle, resembling butterfly wings.
These wings provide greater control during insertion, allowing healthcare professionals to stabilize the needle and minimize patient discomfort.
Components of a Butterfly Needle:
| Component | Description |
|---|---|
| Wings | Flexible plastic tabs used to hold and guide the needle during insertion. |
| Needle | Short, thin, and sharp for precision and comfort. |
| Tubing | A small, flexible tube that connects the needle to a syringe or collection tube. |
| Safety Mechanism | Many modern butterfly needles have a safety lock to prevent accidental needle sticks. |

Anatomy of a Butterfly Needle
Understanding the components of a butterfly needle is crucial for proper use:
- Needle: Typically 21 to 23 gauge, ensuring minimal discomfort.
- Wings: Plastic flaps for better grip and control.
- Tubing: Flexible and transparent, allowing for easy blood flow monitoring.
- Connector: Attaches to a syringe or vacuum tube for blood collection.

Common Mistakes to Avoid
Even experienced professionals can make errors. Here are the most frequent mistakes when using a butterfly needle — and how to avoid them:
- Inserting too deeply – leads to vein puncture or tissue damage.
- Not stabilizing the vein – causes rolling veins and failed draws.
- Reusing equipment – always use sterile, single-use needles.
- Incorrect tube order – can lead to contamination or inaccurate results.

Choosing the Right Butterfly Needle Size
The gauge (G) of a butterfly needle determines its diameter — the smaller the number, the larger the needle.
| Gauge | Common Use | Typical Application |
|---|---|---|
| 18G | Rapid blood collection | 18G Butterfly Needles – Siny Medical |
| 21G | General adult blood draws | Standard phlebotomy |
| 23G–25G | Pediatric or fragile veins | Elderly or oncology patients |
Choosing the right gauge ensures the best balance of flow rate, patient comfort, and sample quality.
Safety and Infection Control
Safety always comes first. According to CDC guidelines, healthcare workers should follow universal precautions when handling needles. Always:
- Wear gloves and protective gear.
- Dispose of used needles immediately.
- Avoid recapping or manual handling.
- Use safety-engineered devices.
Siny Medical’s butterfly needles are designed with integrated safety features, ensuring protection for both patients and medical staff.
