Description
The Terumo Surflo Winged Infusion Set is the classic butterfly set: soft interlocking wings, a precisely honed thin-wall needle and flexible tubing that stays where it is placed. For scalp veins, hand veins and other delicate sites, control at the wings matters more than anything else in the set. Pediatric units, oncology infusion rooms and phlebotomy teams keep these sets ready for the patients whose veins forgive nothing.
- Interlocking Flexible Wings – The soft wings fold together for a firm grip during insertion, then flatten to conform to the skin for taping.
- Needle Bonded at an Angle – The needle sits at just under a 3 degree downward angle to the wings, lowering the risk of vessel damage or lumen occlusion.
- Thin Wall, Precisely Honed – A thin wall cannula with a honed point supports easy penetration and continued access with a single insertion.
- Three Tubing Lengths – Choose 3-1/2 in, 8 in or 12 in tubing to match the working distance of the procedure.
Butterfly Infusion Sets for Delicate Venipuncture
Winged infusion sets exist for the veins that standard catheters struggle with: small, rolling or fragile vessels in hands, feet and scalps. The Surflo design centers on the wings, which are soft, flexible and interlocking, giving the clinician a pinch grip for insertion and a flat profile for secure taping. Terumo bonds the needle to those wings at just under a 3 degree downward angle, a geometry meant to reduce vessel damage and keep the lumen open against the vein wall. The needle itself is thin walled and precisely honed, so a single insertion can establish access for infusion or blood collection. Twelve configurations span 18G to 27G and three tubing lengths, covering everything from rapid infusion to fine pediatric draws.
Features and Benefits
Wing and Needle Design
- Soft Interlocking Wings – The wings readily conform to the body's contour and lock together for a controlled grip at insertion.
- Angled Needle Bond – Bonding the needle just under 3 degrees down positions it naturally along the vessel, reducing occlusion risk.
- Thin Wall Cannula – The thin wall design keeps flow generous for the gauge while the honed point eases penetration.
Tubing and Use
- Flexible Tubing Options – Tubing comes in 3-1/2 in, 8 in and 12 in lengths, so the set can sit close or reach a pump or syringe comfortably.
- Color-Coded Wings – Wing colors follow gauge, making the right set easy to grab during a busy clinic.
- Infusion or Collection – The sets serve intravenous delivery of fluids or drugs and can also be used for blood collection.

Control Where Veins Give No Second Chances
A butterfly set is chosen at the bedside, often for the hardest stick of the day, and it is judged in the first five seconds. Wings that grip well and a needle angled to sit naturally in the vessel turn a tense procedure into a routine one. That bedside confidence is why this set has remained a standard for so long.
- Grip That Becomes Stability – The same wings that give insertion control flatten into a stable, tape-friendly base once placed.
- Angle That Protects the Vessel – The slight downward bond helps the needle rest along the vein instead of pressing into its far wall.
- Sizes for Real Caseloads – Twelve options from 18G infusion duty to 27G fine work mean one product line covers the whole unit.
- Single-Insertion Access – A honed thin-wall needle is made to establish access once, sparing fragile veins repeated attempts.
Frequently Asked Questions
What are these sets used for?
They provide intravenous delivery of fluids or drugs and can also be used for blood collection, especially at delicate sites like hands and scalp veins.

What sizes are available?
Twelve sets span 18G to 27G, with 1/2 in or 3/4 in needles and tubing in 3-1/2 in, 8 in or 12 in lengths.
Are the sets sterile?
Yes. Each set is sterile and intended for single use.
How are they packaged?
Sets come 50 to a box and 10 boxes to a case, and the case is the package sold on this listing.
