Abstract
A portable vein locating device includes one or more infrared illuminators for transmission through a patient'"'"'s skin of infrared light and a vein imaging module for determining the location of a vein beneath the skin by detecting the absence of backscattered infrared light. As the device is passed over a patient'"'"'s skin, infrared light from the infrared illuminators penetrates through the patient'"'"'s skin and is absorbed by veins under the skin but scattered by the fat and other tissues surrounding the veins. Backscattered infrared light from the areas about the veins is detected by the vein imaging module, which includes a number of infrared light detectors, for detecting the backscattered light, and a display, for indicating to the medical caregiver the location beneath the skin of detected veins.
