Wearable multimode brain function detection device based on NIRS-EEG

Abstract

The invention discloses a wearable multimode brain function detection device based on NIRS-EEG. The wearable multimode brain function detection device comprises an NIRS-EEG detection unit, an ultra-low power consumption control unit, a state prompt unit, a Bluetooth communication unit, a key input unit and a power supply unit; the ultra-low power consumption control unit is connected with the NIRS-EEG detection unit, the state prompt unit and the Bluetooth communication unit respectively, the ultra-low power consumption control unit conducts data instruction communication with the NIRS-EEG detection unit through SPI interfaces, the ultra-low power consumption control unit conducts data transmission communication with the Bluetooth communication unit through a UART serial port communication protocol, and the Bluetooth communication unit sends received data to a mobile terminal for subsequent processing; the key input unit is connected with the power supply unit, and the power supply unit is used for supplying power to the NIRS-EEG detection unit, the ultra-low power consumption control unit, the state prompt unit and the Bluetooth communication unit and conducting power supply protection and power management. The wearable multimode brain function detection device has good comfortability, and monitoring on occasions such as the brain cognitive function, neurological and psychiatric diseases and sleep and fatigue states can be conveniently conducted anytime and anywhere.

Description

technical field [0001] The invention relates to a brain function detection device, in particular to a wearable multi-modal brain function detection device based on NIRS-EEG, which belongs to the field of cognitive neuroscience and the research field of vital sign parameter detection devices. Background technique [0002] With the improvement of people's living standards, people's health awareness is increasing day by day, and the awareness of health prevention in the mental and emotional field is particularly prominent. The demand for non-load detection of physiological parameters anytime and anywhere has also emerged. It has gradually become a research hotspot in the field of modern cognitive neuroscience, and more and more valuable information can be obtained through the combination of several different technologies. Among them, electroencephalography (Electro EncephaloGram, EEG) can directly measure the electrical signal of neural activity, and record a specific event-rel...

Problems solved by technology

[0005] At present, the detection function of electroencephalogram (EEG) and cerebral blood oxygen detection function of near-infrared spectroscopy (NIRS) are generally found in monitors in medical and nursing places, which provide an objective vital sign parameter for monitoring and health evaluation. There is no product that combines the two technologies. The existing EEG detection products and near-infrared light brain blood oxygen detection products are not only large in size, have many lead channels, troublesome wiring, inconvenient operation, and poor comfort, but also cause The tension during the test brings psychological pressure and physical load to the tester, which leads to distortion of the results, and most of these testing equipment are concentrated in large hospitals, which is not conducive to the detection of brain function and the protection of the brain health of users anytime and anywhere. know
