New Device Reveals Hidden Blood Vessels
VeinViewer uses near infrared light to reveal the network of blood vessels just beneath the skin.
NEW YORK—A new device that projects the position of veins directly onto a patient's skin is helping take the guesswork out of medical pricks and injections.
The reflected photons are captured by a digital video camera and a computer creates a digital image of the vasculature, which is then projected back onto the patient's skin. The hidden veins appear on the skin as colorless lines that crisscross a rectangular patch of neon green [photo].
The technology works regardless of a patient's age, body type or skin color, VeinViewer's creators say, and it is accurate to about a quarter of an inch.
Made by Luminetx Corporation, VeinViewer is being tested in hospitals across the country and was demonstrated here last week at Wired Magazine's NextFest new-technology forum.
