Vein-viewer System using the Difference of Infrared Ray Absorption Rate Based on Oxygen Saturation

摘要

According to this invention relates to a system, hemoglobin oxygen saturation in finding a vein for venipuncture infrared absorption 720 is equipped with an infrared filter change so that you can take a wavelength of ~ 740nm modyulwa camera, and a microprocessor to process the photos taken from the camera module, and a projector to display the processed image back onto the human skin, processed by the microprocessor relates to a video signal to find a vein of the human body using the infrared absorption difference in oxygen saturation as a monitor configured to be able to see on the screen the system. According to facilitate finding a vein of the human body using the infrared absorption difference in oxygen saturation of the invention the system may find a vein, the vein located exactly at a time can be inserted several times, the intravenous needle to find the blood vessel as there is an effect that can prevent nerve racking that is causing the problem happens to the health of the patient. ;
