Created a scanner for veins

To make an injection, you often need to find a vein. To place a catheter, too. But often the main difficulty lies not in administering the medicine, but in detecting the vein. When treating children and the elderly, finding a vein may turn out to be another quest.

And you have to look for a vein by piercing the skin in several places. It hurts, so such a search becomes a real torment for the patient. To make the procedure less unpleasant, scientists created a vein scanner. It allows you to find a vein in a non-invasive way. Fast, painless and accurate.

The vein scanner uses harmless near-infrared (NIR) light, which is directed at the patient’s skin. Hemoglobin in the blood absorbs NIR, and the surrounding tissue reflects it. The scanner processes the information received, visualizes it, adds color and projects it onto the skin. You can see the location of blood vessels in real-time and drawings of veins located under the skin at a depth of 10 mm. And all this without gels and other materials. Pure LED projection.

According to nanonews.net, the technology of digital imaging provides the doctor with a clear and precise visualization, which is very important in a situation when working with difficult veins. The doctor does not need to look towards the monitor or use any additional equipment to gain access to the vein.

The device will help reduce vein search time, which is very important. In addition, the ability to reduce tissue trauma (I mentioned above repeated punctures) greatly simplifies the patient's life, if I may say so. And for the doctor there is less work and additional risks, and this is also important.
