| Authors: | Abstract |
| Abstract: | A reflecting oximeter,based on the principle that blood optical absorption(or reflection)intensity is in fixed relation with blood oxygen saturation,measures the blood oxygen saturation under extracorporeal circulation in heart surgery. It consists of a converter,a driver and a central processor module,as well as a liquid-crystal display module.A one-to-three optical-fiber cable connects the reflecting probe,the central background processing system and the digital display system.It successfully resolves the problems in sensitivity and stability of the oximeter.It has such advantages as simple in structure,low in costs,and reliable in performance,etc. |
