Terumo SurFlo Winged Infusion Sets provide soft, flexible interlocking wings that readily conform to the body's contour. The wing is angled for ease of positioning of the needle during venipuncture. The SurFlo Wing Infusion Set provides less risk of vessel damage or occlusion of the lumen. The precisely honed needle with Ultra-Thin wall design assures ease of penetration and continued access with a single insertion. The Therumo SurFlow is DEHP Free.
