Wearable brain function detection device based on NIRS

Abstract

The invention discloses a wearable brain function detection device based on NIRS. The wearable brain function detection device comprises an NIRS 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, wherein the ultra-low power consumption control unit is connected with the NIRS detection unit, the state prompt unit and the bluetooth communication unit respectively, is in data command communication with the NIRS detection unit through an SPI interface, controls the working mode of the NIRS detection unit, and is in data transmission communication with the bluetooth communication unit through a UART serial communication protocol, and the bluetooth communication unit sends the received data to a mobile terminal for follow-up processing; the key input unit is connected with the power supply unit, the power supply unit is used for providing electricity for the NIRS detection unit, the ultra-low power consumption control unit, the state prompt unit and the bluetooth communication unit, and carries out power supply protection and power management. The wearable brain function detection device is small in size, the detection result is accurate, the power consumption is extremely low, and the real-time monitoring on the brain blood-oxygen based on NIRS is convenient.

Description

technical field [0001] The invention relates to a brain function detection device, in particular to a wearable brain function detection device based on NIRS, which belongs to the research field of vital sign parameter detection devices. Background technique [0002] The brain accounts for about 2% of the total body weight, but it receives about 15% of the cardiac output, and its oxygen consumption accounts for about 20% of the whole body's oxygen consumption. Prolonged hypoxia will lead to irreversible damage to the brain tissue. In addition, various activities of the human brain can be directly observed by measuring the activity state of the cerebral cortex. Near-infrared Spectroscopy (Near-infrared Spectroscopy, NIRS) is currently the only technique that can simultaneously measure cerebral hemodynamics and neural tissue activity, which is of great significance for brain health and cognitive identification, because of its non-invasive and Mobility has very important clinic...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the NIRS measurement devices in the clinic and on the market are multi-conductor devices, which are inconvenient to use, and too many leads will affect the user's measurement experience

Secondly, the data acquisition and processing modules of existing NIRS devices use separate devices, which are easily disturbed by external noise and internal electromagnetic compatibility, and it is difficult to meet the needs of measurement anytime and anywhere.

Thirdly, most of the existing devices are limited devices and are not easy to move. Even wireless devices mostly use Bluetooth 4.0 communication, the transmission efficiency is not high, and they have to be paired with other devices every time, which is not easy to use
