Infrared Based Vein Detection: Comprehensive Review

This project focuses on the development of an affordable and efficient vein detection system leveraging near-infrared (NIR) light technology.The primary goal is to address challenges faced during phlebotomy and intravenous (IV) procedures, particularly for patients with difficult-to-locate veins, such as those with obesity, dehydration, or certain medical conditions.The system utilizes NIR light to enhance vein visibility by exploiting the optical properties of blood, which absorbs more NIR light than the surrounding tissues.Captured images are processed using advanced image processing algorithms to improve the clarity and contrast of the veins, ensuring their distinct visibility.This enhanced visualization aids healthcare professionals in accurately identifying vein locations.To further assist in the procedure, the system incorporates a laser-guided alignment mechanism.
