Abstract

Visible Light Vein Finding is a clinical technique that uses high-power red light for locating veins beneath the skin. This technique Uses a device with arranged red-light LEDs which can be used during accessing the veins for illuminating the tissues around the veins to darkening the veins shadows for locating them. In designing this product we were faced with many criteria such as limitation in head part for avoiding interrupt in clinical procedures, best arrangement of led for better illumination, and some limitation in body part such as hand griping items and to find the locations for internal components like battery and PCB.
