High-precision low-power-consumption multi-channel brain deep electroneurographic signal wireless collecting system

Abstract

A high-precision low-power-consumption multi-channel brain deep electroneurographic signal wireless collecting system comprises eight-channel brain deep cerebral nuclei electric signal collecting electrodes, any collecting electrode is selected freely by an analog multiway switch to collect brain deep cerebral nuclei electric signals, collected analog signals are directly input into an AD collecting module for preprocessing and A / D conversion, and converted data are stored in a data storage module through an MCU. After data are collected for certain time, the stored data are transmitted to the other MCU through a sending RF wireless transmission module and a receiving RF wireless transmission module, and then the data are transmitted into an upper computer to be displayed and further processed through an USB interface. The brain deep cerebral nuclei electric signals are collected, and an effective cerebral nuclei signal collecting tool is provided for exploring the therapeutic mechanism and action principle of a DBS, and the pathogenesis of the Parkinson's disease, an essential tremor and a series of neurological diseases.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a high-precision, low-power consumption, multi-channel wireless deep brain electrical signal acquisition system. Background technique [0002] Deep Brain Stimulation (DBS) is an effective neuromodulation technology, mainly by implanting micro-brain electrodes in a specific area deep in the brain, and generating a stimulation sequence with certain parameters through a pulse generator embedded in the body. Altering local neuronal firing properties to alleviate and treat disease. DBS directly changes local brain activity in a controllable way, can effectively control symptoms for a long time without causing permanent damage, is a reversible treatment method, and is the only neurosurgical method that allows black-box research. At present, DBS is mainly used for the treatment of Parkinson's Disease (Parkinson's Disease, PD), chronic pain, essential tremor (Essential Tr...

Problems solved by technology

Therefore, these disclosed EEG collection devices are not suitable for the collection of discharge signals of deep brain nuclei

In addition, the power consumption and volume of these products are very large, which is not easy to carry and move, and the above products are basically collected based on 12 or 24-bit AD conversion chips. Due to the accuracy of the chip itself, the AD conversion chip The last few digits are unreliable and cannot meet the ideal accuracy requirements
