Embodiment approach 2

[0086] Reference attached figure 2 , an EEG-based epilepsy detection and intervention device includes two parts inside and outside the body. The external part includes: recording electrodes 13 , EEG acquisition circuit 2 , EEG analysis module 3 , wireless communication module 31 and storage module 6 . The internal body includes: a pulse generating circuit control unit 41 , a pulse generating circuit 4 , and stimulating electrodes 14 .

[0087] Different from the first implementation, the second implementation moves the EEG acquisition circuit and EEG analysis module that require strict low-power design to the outside of the body, so that these two parts are no longer limited by power consumption. also decrease. In this way, the external circuit does not need to select components with small size, low power consumption and high cost; the detection algorithm does not need to be optimized for a large number of calculation efficiency, and can run on a processor with faster calcu...

Embodiment approach 3

[0099] Refer to attached image 3 , an EEG-based epilepsy detection and intervention device includes: a recording electrode 13 , an EEG acquisition circuit 2 , an EEG analysis module 3 , an alarm module 5 and a storage module 6 . The device collects EEG through the recording electrode 13 arranged on the scalp and the EEG acquisition circuit 2 , and records it on the storage module 6 under the control of the EEG analysis module 3 . The EEG analysis module 3 runs the epilepsy detection algorithm to determine whether there is an epileptic seizure, and sends the result to the alarm module 5 for the patient's family members, doctors, and nurses to intervene in response to the patient, instead of using a machine to directly intervene in the patient.

[0100] Different from the first two implementations, the third implementation does not have fully implanted components, and the epilepsy detection algorithm does not directly intervene after detecting an epileptic seizure, but notifies...

Abstract

The invention provides an electroencephalograph (EEG)-based epilepsy detection and intervention device, which has the functions of recording EEG (scalp EEG, electrocorticogram (ECoG) and deep local field potential (LFP) EEG), analyzing the recorded EEG, detecting epilepsy electrograph onset (EO), forecasting epilepsy behavior onset and giving an alarm about the forecast epilepsy onset or implementing intervention means such as electrical stimulation. The device can also be used for research of corresponding animal experiments.

Description

technical field [0001] The invention relates to an epilepsy detection and intervention treatment device and an epilepsy detection algorithm based on EEG (scalp EEG, cortical ECoG, and deep brain local field potential LFP) of experimental animals such as human or rat, rabbit, monkey, etc. The invention can be used for a closed-loop feedback neural stimulator with automatic detection and on-demand stimulation or an external epilepsy detection and alarm device. The device and method can also be used in corresponding animal experimental researches for epilepsy detection and intervention, and belong to the field of implanted medical instruments. Background technique [0002] Implantable neurostimulators are a type of implantable medical devices that treat certain diseases by emitting electrical stimulation to the nervous system. At present, they have been put into clinical use all over the world or are in the development and registration stage, mainly for the treatment of Parkinso...
