AbstractThe main purpose of this paper is to describe the design and development of the near-infrared blood-oxygen monitor which is based on the theory of detecting the blood-oxygen parameters of tissue by near-infrared, and the monitor can detect the blood-oxygen parameters of two sides of the local brain tissue. The monitor uses two wavelength ultra-high light LED as lamp-house, and two sensors detect the light scattered by two sides of the local brain tissue, which make the monitor achieve the function of dual detector. The appearance of the monitor's detector is designed to reduce effectively the noise brought by the background and alleviate the discomfort feelings of the patient. At the same time, this apparatus can monitor continuously the brain blood-oxygen parameters of the patients in real time, and output the curves of the blood-oxygen and oxygen concentration of two sides of brain tissue. At last, the biological model experiments and the tests in clinical setting validate the monitor.
