Wearable epilepsy brain-electricity seizure brain area positioning device and method

Abstract

The invention discloses a wearable epilepsy brain-electricity seizure brain area positioning device and method. The device comprises an acquiring electrode, a brain-electricity acquiring chip, a conditioning circuit, a micro-controller, a Bluetooth transmitting module and a Bluetooth receiving module. The method comprises the following steps: transmitting acquired signals to the conditioning circuit by the brain-electricity acquiring chip; carrying out amplification and filtering preprocessing on the acquired brain-electricity signals by the conditioning circuit, and transmitting the brain-electricity signals to a microprocessor; synchronously transmitting data to an mobile phone APP and displaying the data in real time by using a Bluetooth technology, and transmitting the data to a cloud; downloading brain-electricity signals of various channels of a patient by using a terminal of an upper computer from the cloud, extracting features of the received brain-electricity data by using a feature recognition algorithm, and recognizing abnormal epileptic waves. By the wearable epilepsy brain-electricity seizure brain area positioning device and method, brain-electricity change conditions before and after epilepsy seizure of the patient are acquired, transmitted and monitored in real time, and an epileptic focus is positioned accurately; and a Bayesian linear discriminant analysis algorithm is adopted to fulfill a function of automatically examining and positioning epilepsy brain-electricity signals.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a wearable device and method for locating epileptic EEG brain regions. Background technique [0002] Epilepsy is one of the most common neurological disorders worldwide. Epilepsy is characterized by a persistent susceptibility to seizures and associated neurobiological, cognitive, psychological, and social consequences. Epilepsy is a clinical event characterized by recurrent, stereotyped, and unpredictable behavior, and is a clinical manifestation of paroxysmal abnormal hypersynchronized electrical activity of neurons in the brain. Since the essence of epilepsy is the paroxysmal disorder of neuron electrical activity, EEG plays an important role in the diagnosis and treatment of epilepsy. [0003] Accurate localization of epileptic foci in the brain is a prerequisite for surgical treatment of epilepsy. At present, there are two commonly used EEG positioning diagnosis methods in ...

Problems solved by technology

However, AEEG requires patients to lie on the hospital bed for 24 hours, which not only restricts the activities, but also makes the hospital beds more tense to some extent.

[0004] In clinical practice, the existing electroencephalograph has the following disadvantages: firstly, the patient cannot move freely during the examination, especially the long-term continuous monitoring of children's patients often cannot achieve good results; secondly, the 24-hour monitoring It not only takes up the patient's time, but also worsens the crowded phenomenon of hospital beds; third, the anti-interference is poor, and it is easy to cause waveform distortion
