Winged Infusion (Butterfly) Set 23G × 3/4" — 50/Box

Winged infusion sets with a 23G, 3/4 inch needle, supplied 50 per box. The flexible wings give the fingers a stable grip during insertion, and the attached tubing allows the line to be secured while the needle stays anchored during short procedures.

Winged sets are typically used for short-term access, single infusions, blood sampling and situations where a cannula is not warranted. Gauge and length are selected against the patient and the therapy.

What do 23G and 3/4 inch mean at the point of insertion?

23G is 0.6 mm nominal outside diameter, and 3/4 inch is 19 mm. ISO 6009:2016 sets the colour code for single-use hypodermic needles, and 23G is blue, so the hub colour is a quick cross-check that the set in the drawer matches the gauge on the box. Gauge sets flow: a 23G needle carries most routine infusions and blood sampling at a rate that suits gravity or a small pump, while 21G is faster and 25G is slower and gentler on the vein. Length decides whether the tip sits in the lumen or pushes through the wall; 19 mm is a mid-range length that suits most adult forearm and hand veins, with shorter and longer lengths reserved for small or deep veins. Needle selection is a clinical decision. What procurement controls is that the code on the box, the code in the protocol and the colour on the hub all agree.

When is a winged set the right device, and when is a cannula better?

A winged set suits a defined episode: one infusion, one blood draw, a short day procedure, or a patient whose veins are too fragile for a cannula. The wings give a stable grip during insertion and a flat surface to tape down, and the tubing lets the line be secured without loading the needle. A cannula is the better device when the patient needs repeated access over hours or days, because it stays in place and spares further punctures. Leaving a winged set in longer than its intended short use is where infiltration and phlebitis begin, and the failure is usually recorded against the product when it belongs to the device choice. Decide by therapy duration first, then gauge, then length.

Which standards cover the needle and the connector?

The needle component follows the single-use hypodermic needle requirements of ISO 7864:2016, which covers designated metric sizes from 0.18 mm to 1.2 mm; 23G at 0.6 mm falls inside that range. The tubing connector is a small-bore connector, and the current document for intravascular and hypodermic connections is ISO 80369-7:2021, second edition, which replaced the earlier Luer standard series. A set built to the older connector can be physically incompatible with a device built to ISO 80369-7, which is why connector conformance belongs on the specification sheet rather than in a footnote. Where a sharps protection feature is fitted, its performance is evaluated against ISO 23908:2011. Sterility and packaging follow the pattern used for other single-use devices: ISO 11135:2014 for ethylene oxide, the ISO 11137 series for radiation, and ISO 11607-1:2019 for the sterile barrier system.

How should a winged set be secured and removed?

Secure the wings with tape that does not compress the hub, loop the tubing once and tape the loop so that a tug pulls the loop rather than the needle, then check blood return and flow before the infusion starts. On removal, place gauze over the site, withdraw along the line of insertion, apply pressure until bleeding stops, and put the set straight into the sharps container at the point of use rather than on a trolley. Recapping by hand is the manoeuvre that produces needlestick injuries, so the set goes in needle first. Document site, gauge, time and any reaction; a cluster of failures at one site is a technique signal, not a product signal.

What should be verified before a clinic accepts a batch?

Check the label against the requisition for gauge, length and box count; check the sterile barrier for damage and confirm the expiry date; confirm the connector type; and confirm the supplier can produce a declaration of conformity citing the standards above. Keep the lot number with the batch record. A winged set is a low-cost item with a high-cost failure mode, a needlestick or an infiltrated infusion, so the batch record matters more than the unit cost. Our 70% isopropyl alcohol prep pads and red biohazard waste bags are specified the same way, and the compliance log centre holds printable forms for batch receipt and sharps replacement. Volume sourcing runs through the wholesale enquiry desk, and the wider consumable list is mapped in our guide to IV infusion clinic consumables.

Frequently asked questions

When is a winged infusion set used instead of a cannula?

For short procedures, single infusions or sampling where a dwelling cannula is unnecessary. Choosing between the two is a clinical decision based on therapy duration and patient factors.

What does the gauge affect?

Flow rate and vessel trauma: a smaller gauge number is a larger needle, allowing faster flow but less comfortable insertion.

Do winged sets need sharps disposal?

Yes. The needle is a sharp, and any set with an exposed needle goes into a sharps container immediately after use.

Can I source these for a home infusion program?

Use our B2B enquiry form with your annual volume and we will confirm documentation status.
