Australians introduced a device for easy vein detection

A group of specialists from Australia has developed a device that allows you to easily detect veins on the patient's arm. The problem of finding a vein in the arm is quite relevant for many people. If the vein is difficult to find, the nurse may insert the needle several times into the arm until it enters the vessel.

For the detection of a vein, near-infrared radiation is used.

The radiation of this spectrum is absorbed by hemoglobin molecules, unsaturated with oxygen. And since the blood flowing to the veins is poor in oxygen, it is the veins that are highlighted.

Radiation is safe for health, but it is not recommended to shine in the eyes (actually, why do this?). The device is used in Australian Red Cross Blood , a medical service that works with donors. In the near future, the scanner is used when working with several hundred volunteer donors. At the same time, experts hope that the device of the new type will allow to attract young volunteers to donate who will be interested in this technology of blood screening.

Here is a video demonstrating the operation of the device:
