The SURFLO® Winged Infusion Set features a precisely honed needle with ultra thin wall design that assures ease of penetration and continued access with a single insertion. An exclusive, silicone lubricant provides smoother needle passage through tissue. And with the needles bonded to the wings at a slight downward angle, there is less risk of vessel damage or occlusion of the lumen. Soft and flexible, the wings readily conform to the body contour.
