Tech projects vein maps during blood donations

The Australian Red Cross Blood Service is testing a technology to project a vein map on the arms of blood donors during the phlebotomy.

"Vein visualisation technology uses near infrared technology to project an image of the vein onto the skin," says Dr. Dan Waller, a senior researcher with the organization. "Veins have a lot of deoxygenated haemoglobin that absorbs near infrared light and the device is able to use this information to project the image. The machines have settings to manage individual differences.
