According to the study, about one-third of stroke (stroke) patients have symptoms of stroke when they are not discharged. Therefore, nurses in the intensive care unit will keep an eye on them and ensure their safety through real-time monitoring equipment such as blood oxygen saturation, heart rate and blood pressure. However, due to the complexity of the human body, changes in local tissue usually precede changes in the overall physiological function. Therefore, irreversible damage of local tissue function often occurs. In stroke patients, due to the presence of the blood-brain barrier, this irreversible damage usually occurs quietly and eventually causes fatal harm. At present, with the promotion of near-infrared light technology in the field of monitoring tissue oxygen saturation, more and more medical institutions and doctors have begun to use this technology to monitor and evaluate the condition and recovery of stroke patients in real time. , greatly improving the safety of patients.
Using near-infrared spectroscopy (NIRS), according to the generalized Lambert-Beer, one can achieve a non-invasive measurement of blood oxygen concentration in tissues such as the body brain and skeletal muscle. In turn, the organization has a comprehensive understanding of tissue oxygen consumption and blood supply in different environments. The study found that stroke can cause local tissue blood supply and oxygen supply abnormalities. Using brain tissue oxygen saturation monitoring can effectively assess the severity of the disease and have a good guiding effect on the prognosis and subsequent rehabilitation effects. In addition, the brain function partition (nuclear group) will have significant blood supply and oxygen supply changes under different task loads. Using tissue oxygen saturation monitoring, it can effectively evaluate the extent of the lesion, and then carry out targeted treatment and functional recovery. At present, the technology is widely used in brain function research such as cognitive psychology and work load, in addition to real-time monitoring of stroke patients, assessment of functional area damage, and observation of therapeutic effects.
Different near-infrared light absorption spectra and functional diagrams of oxyhemoglobin (HbO 2 ) and reduced hemoglobin (Hb)
In the near-infrared light brain functional imaging equipment of the existing market, the OEG-SpO2 near-infrared light brain functional imaging analyzer produced by Spectratech of Japan is characterized by its portability, high cost performance, and direct testing of brain blood oxygen saturation. Widely known. The device uses maximum spread spectrum technology and ultra-high signal-to-noise ratio design to perfectly identify ultra-weak pulse signals and simultaneously measure hemoglobin (Hb) and tissue oxygen saturation (SpO 2 ) on the surface of brain tissue. With 16 channels and a 5-person test, the device helps researchers conduct brain function studies from the cerebral circulation & metabolic pathways. At present, it has become an important research instrument in the field of clinical medicine, sports science and psychological cognition. This product is exclusively represented by Beijing Century Tianhong Scientific Instrument Co., Ltd. in China. Century Tianhong will team up with Spectratech of Japan to provide strong technical support for users, from the aspects of equipment installation, application and research. A full range of services.
