Surshield Safety Winged Needle sets have the soft, flexible, interlocking wings that readily conform to the body?s contour. The needles are bonded to the wings at just under a 3 degree angle, for less risk of vessel damage or occlusion of the lumen. The coil resistant tubing reduces recoil during use. Surshield Safety Needle sets are DEHP free and have no components made of natural rubber latex.
