Even the most skilled nurses and doctors can struggle to locate the vein first time. So hospitals in the US are trialing a device that can locate veins inside a person’s arm using harmless near-infrared light.
This device is called as Christie Vein Viewer. This device detects veins and then projects the image of them in real time on top of the arm to help the medical worker know where to put the needle.
According to online publishers, this provides an accurate image of the patient’s blood pattern. It can see patterns up to 15mm deep, and veins up to 10mm deep. A fine detail mode also increases the contrast in the image, bringing out more detailed vein formations. This can allow a clinician to find turns in a person's veins, called bifurcations, and valves. The user can also take up to 200 static images of patient vasculature - the arrangement of blood vessels in the body.
