Portable Vein Visualization Device Uses Non-Invasive Near Infrared Technology
The Australian Red Cross Blood service is conducting research into the use of leading-edge technology to visualize blood donors' veins during blood donation. The vein visualization devices are portable, and project an image of the veins onto the skin's surface using non-invasive near infrared technology. 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. The Blood Service is aiming to find out if this procedure reduces anxiety, improves donation comfort, and makes donors more likely to donate again.
