Abstract. The article is devoted to the use of optical sensors in the medical device for the diagnostics of the human’s organism blood-vascular system state. Blood is one of the main organism fluids. Many somatic diseases are diagnosed according to its state, besides there are system blood diseases. So the problem of blood flow diagnostics is quite urgent. In the article the device measuring blood saturation with oxygen and blood velocity is described. Optical fiber acts as a sensor and informational line. The method of two wave lengths is used to increase measurement accuracy.
