Winged Collection Sets

Winged Collection Sets

Winged blood collection sets or “butterfly” collection sets can facilitate blood specimen collections when larger quantities of blood are needed, when the patient’s veins are fragile or difficult to access using a straight needle, and with patients who have trouble remaining still or immobile during blood specimen collection. Typically available with shorter and smaller needles, winged collection sets can also be more comfortable for patients.

The “wings” refer to flexible flat plastic pieces attached to either side of the needle base. They attach to the needle at a slight angle to help avoid blood vessel damage or lumen occlusion. Since the needles are not stabilized by a syringe or tube holder, the phlebotomist can pinch the wings together to use as a handle to control the needle placement. After insertion, the wings can then be spread open and taped to the skin to comfortably maintain the needle position during the blood draw.

Find winged blood collection sets with varying attached tubing lengths, needle gauges and lengths, and with Luer and non-Luer connection options.

Set Components

Winged blood collection sets have a six-or 12-inch lengths of tubing attached to the back of a needle. The tubing, which should not kink, curl, or clog, usually ends with a Luer connector. Some tubing is pre-attached to a blood tube holder for convenience or to help maintain sterile conditions.

Many winged collection sets are also equipped with passive or active needle covers and caps to help avoid accidental needlesticks. Needles are usually available in lengths of one or one and a half inches and in gauges between 21 and 25.

Winged blood collection sets are also used for infusing fluids and medications and are intended for a single use.
