Implantable closed-loop self-response system and method for electroencephalogram signal storage and transmission

Abstract

The invention relates to an implantable closed-loop self-response system for electroencephalogram signal storage and transmission. The implantable closed-loop self-response system comprises an implantation device and an in-vitro device, wherein the implantation device comprises a signal acquisition module for acquiring an electroencephalogram signal, an MCU for analyzing the electroencephalogram signal, a storage module for storing the electroencephalogram signal and an in-vivo communication module for transmitting electroencephalogram; the in-vitro device comprises an upper computer; a wireless communication module is arranged in the upper computer; and the MCU is electrically connected with the signal acquisition module, the storage module and the in-vivo communication module respectively. According to the implantable closed-loop self-response system, the MCU implanted into a body is used for caching electroencephalogram data; and when recording is started according to an instruction of the upper computer or the MCU, the cached data is transmitted into the storage module, compressed and stored; the implantation body transmits the data to the outside through the wireless communication module, so that the electroencephalogram recording capability of the implantation body is enhanced.

Description

technical field [0001] The invention belongs to the field of signal transmission, and in particular relates to an implanted closed-loop self-response system and method for storing and transmitting electroencephalogram signals. Background technique [0002] An EEG amplifier is an acquisition device that acquires brain signals in a non-invasive way. However, since EEG signals are submerged in environmental noise, when using analog circuits to remove noise, the analog circuits often cannot improve common-mode rejection due to limitations such as offset voltage. ratio, and the increase of analog devices will also increase device noise, so the signals collected by conventional EEG amplifiers are not only limited in frequency band, but also contain some noise interference, which not only increases the difficulty of subsequent processing but also reduces the Affecting medical and scientific progress [0003] Although the EEG acquisition devices disclosed in CN103519807, CN20122042...

AI Technical Summary

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
