The Surshield Safety Winged Blood Collection Sets have soft, flexible, interlocking wings that readily conform to the body's contour with the needles bonded to the wings at just under a three degree angle to reduce risk of vessel damage or occlusion of the lumen. With a simple, built-in safety design that is easy to use, it minimizes the risk of needlestick injuries and does not require any change in the needle insertion technique.
