It’s not exactly the most pleasant experience, and many people are told that their veins are tricky to find. But now, a device that shows a glowing map of your veins could make the whole process a lot easier, and trials of the technology have already begun in Australia.
It may look a little radioactive, but the device is very safe. It works by shining near-infrared light onto your arm, which gets absorbed by the deoxygenated hemoglobin that’s floating around your blood. This creates a glowing green image of your veins that nurses can use to guide where the needle goes in.
