The invention discloses an adaptive blood oxygen signal acquisition probe, device and method based on near infrared blood oxygen detection. The probe comprises a flexible liner and light source and aplurality of photoelectric sensors, which are fixed on the flexible liner, wherein the plurality of photoelectric sensors are arranged on the flexible liner, and are arranged in a straight line with the light source, and the photoelectric sensors are positioned on the same side of the light source; a signal analysis and controller connected with the probe and a display screen are also arranged inthe acquisition device; the signal analysis and controller receives an emergent light signal collected by each photoelectric sensor, analyzes and calculates the emergent light signal of each path, anddetermines two emergent light signals as effective data channels for calculating blood oxygen data; and calculated values and curves are displayed via the display screen. By different detection distance distribution, multi-group and multi-tissue coverage is achieved, the probe is suitable for detecting detection parts of different groups, and the problems about universality of the probe and matching of the detection probe in the near infrared blood oxygen detection process is solved.
Description
technical field [0001] The invention relates to the technical field of blood oxygen detection, in particular to an adaptive blood oxygen signal acquisition probe, device and method based on near-infrared blood oxygen detection. Background technique [0002] Near Infared Spectroscopy (NIRS) is an important branch of biomedical optics. Based on the optical properties of human tissue in the near-infrared band (700-900nm), this technology can detect the blood oxygen parameters of human tissue in a real-time, non-destructive and contact manner. One of the main detection indicators is blood oxygen saturation. [0003] The blood oxygen detection device based on near-infrared spectroscopy is mainly attached to the detected part through an optical sensor, and the optical sensor detects the light signal scattered by the tissue for calculation. During the detection process, since the signal needs to pass through the deep tissue of the detected part, the probe signal is affected by man...
