Glossary Entry: Winged Infusion Set


Definition: A winged infusion set, also known as a butterfly needle, is a medical device used to access a patient’s vein for the purpose of drawing blood or administering fluids or medications.

Detailed Description

Types and Variations

Variations: There are various sizes and models of winged infusion sets, with different needle gauges and wing sizes, allowing for flexibility in use across different patient populations.


Common Uses: Winged infusion sets are commonly used in situations where a patient’s veins are difficult to access, such as in pediatric or geriatric patients, or for procedures requiring a more delicate touch.

Insertion and Placement

Procedure: The winged infusion set is typically inserted using a gentle, butterfly-like motion, and the winged tabs are then pressed against the skin to stabilize the needle during use. Careful attention should be paid to avoid puncturing the opposite wall of the vein.

Clinical Considerations

Potential Complications

Risks: Potential complications of using a winged infusion set include vein bruising, infiltration of fluids into surrounding tissues, or accidental puncture of the opposite vein wall.

Care and Maintenance

Maintenance Requirements: After use, proper disposal of the winged infusion set is essential to prevent needlestick injuries. Additionally, regular inspection of the set for damage or contamination is important to ensure patient safety.

Additional Information

Related Devices

Associated Terms: Other devices commonly associated with winged infusion sets include extension tubing and syringes for fluid administration.

Innovations and Advancements

Recent Developments: Recent advancements in winged infusion sets have focused on improving needle sharpness and reducing the risk of accidental needlesticks, as well as the development of safety-engineered sets.

Regulatory and Safety Notes

Regulations: Winged infusion sets should be used in accordance with local medical device regulations and safety guidelines to minimize the risk of needlestick injuries and other complications.
