Full-implantable brain-computer interface system

Abstract

The invention belongs to the field of implantable medical equipment, particularly relates to a full-implantable brain-computer interface system, and aims to solve the problems. The system comprises: afull implant unit, comprising an electrode, a front-end collector, a microprocessor, a temperature sensor, a wireless communication module, a wireless power supply module, an MICS wireless communication antenna and an HF wireless power supply antenna, used for acquiring an electroencephalogram signal of a measured object and sending the electroencephalogram signal to the external monitoring unit,acquiring the working temperature of the full-implantation unit and adjusting a system working mode and alarm information in combination with a set temperature threshold value, and sending the systemworking mode and the alarm information to the external monitoring unit; and an external monitoring unit, comprising a microprocessor, a wireless communication module, an energy radiation module, a battery, an MICS wireless communication antenna and an HF wireless power supply antenna, used for receiving information transmitted by the full-implanted unit. The system can detect electroencephalogramsignals with high temporal-spatial resolution and has the advantages of being small in size, low in load, flexible in configuration and not prone to infection.

Description

technical field [0001] The invention belongs to the field of implantable medical equipment, and in particular relates to a fully implantable brain-computer interface system. Background technique [0002] Brain-computer interface technology is a technology that does not rely on conventional peripheral neuromuscular tissue and directly uses computer signals to interact with external devices. It provides a solution for the treatment and rehabilitation of those with sensory or motor dysfunction, and has a wide range of application values ​​in the fields of medical treatment and rehabilitation, military and entertainment. [0003] According to the different ways of signal sources, brain-computer interfaces can be divided into two categories: non-implantable and implantable. Non-implantable brain-computer interface technology is to place electrodes on the scalp to extract EEG signals. The acquisition method is non-invasive. Yes, but the signal-to-noise ratio of the scalp EEG sign...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, the brain-computer interface cannot be fully implanted due to power consumption and large volume, and the semi-implantable brain-computer interface is susceptible to infection, heavy load, and inflexible. Implantable brain-computer interface system, the brain-computer interface system includes a fully implanted unit and an external monitoring unit;
