Embodiment Construction

[0060] In recent years, there have been more and more researchers at home and abroad researching and developing non-invasive cerebral blood oxygen monitoring equipment. However, as far as the current domestic situation is concerned, mature equipment is still scarce, while foreign non-invasive cerebral blood oxygen monitoring equipment is expensive to purchase and expensive to diagnose. High, the domestic penetration rate is not high. Therefore, the proposal of the present invention can effectively fill up some vacancies in this field, and provide certain support for the development of domestic cerebral blood oxygen monitoring equipment. For the monitoring of cerebral blood oxygen signal, due to the particularity of its application environment, such devices are often used in the clinical operation environment, so it is necessary to fully consider the monitoring site and the type of monitoring parameters. First of all, the object of the present invention is the patient undergoin...

Abstract

The invention discloses a brain blood oxygen non-invasive monitoring device which comprises a brain blood oxygen information acquisition probe, a non-invasive acquisition subsystem and a monitoring processing subsystem, and an area, corresponding to a brain prefrontal lobe, of the head of a human body serves as a brain blood oxygen non-invasive monitoring area. Red light absorption conditions of a brain blood oxygen noninvasive monitoring area are collected to serve as characterization values of human head tissue interference signals, and infrared light absorption conditions of two different wavelengths of the brain blood oxygen noninvasive monitoring area are collected to serve as characterization values of brain oxyhemoglobin concentration and brain reduced hemoglobin concentration respectively. Furthermore, a brain oxyhemoglobin concentration value and a brain reduced hemoglobin concentration value which do not contain human head tissue interference signals are obtained through processing, and continuous real-time monitoring on the brain blood oxygen value can be stably and accurately realized. A new solution is provided for brain blood oxygen non-invasive monitoring, stability and accuracy of brain blood oxygen non-invasive monitoring are improved, and clinical application of brain blood oxygen non-invasive monitoring is promoted.

Description

technical field [0001] The invention relates to the technical field of biomedical signal acquisition and processing, in particular to a non-invasive monitoring device for cerebral blood oxygen. Background technique [0002] Oxygen is an important substance to maintain the metabolism of the human body. Hypoxia in human tissue is an important cause of certain diseases, and may even have serious consequences, directly threatening life. The blood oxygen saturation of human tissue is an important parameter reflecting tissue oxygen supply and has extremely important clinical value. [0003] Brain tissue has a high metabolic rate, and its oxygen consumption accounts for 20% of the whole body's oxygen consumption, and it is particularly sensitive to hypoxia. Short-term hypoxia may cause irreversible damage to the central system. Brain protection is an important issue in cardiovascular surgery under deep hypothermic circulatory arrest, endovascular surgery in neurosurgery, first ai...
