Embodiment Construction

[0031] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and embodiments.

[0032] figure 1 It is a functional block diagram of an EEG monitoring device and method with epileptic seizure prediction function proposed by the present invention. like figure 1As shown, the EEG monitoring device with epileptic seizure prediction function in the embodiment includes an EEG signal acquisition device, an EEG analysis and epilepsy prediction device, and an epilepsy alarm device. First, the EEG signal acquisition device in this embodiment directly adopts a hospital EEG monitor, and the collected data is the patient's buried cortical EEG data, and the data sampling rate is 512Hz. Second, the EEG analysis and epilepsy prediction device includes an EEG data preprocessing module and an epilepsy prediction algorithm module based on a directed transfer function. In this embodiment, the EEG data preprocessing module performs 0...

Abstract

The invention discloses an electroencephalogram monitoring device with an epileptic seizure predicting function and a method. The electroencephalogram monitoring device and method can be applied to ascalp electroencephalograph machine or an embedded cortex electroencephalogram monitoring system. The method of the device comprises the following steps of 1, acquiring an electroencephalogram signalof a patient through an electroencephalogram acquisition device; 2, transmitting the electroencephalogram signal to an epileptic predicting alarming device; 3, judging the state of the patient throughan epilepticprediction algorithm module in the epileptic predicting alarming device, and once the epileptic measurement module judges that the patient is in the early stage of anepileptic seizure, sound-lightalarm can be triggered, and the patient and his / her dependents are prompted to take prevention measures. The epilepticprediction algorithm moduleuses a directed transformation function as a basis and characteristics of a connection matrix among electroencephalogram signals as parameters for predicting the epilepticseizure of the patient, the epileptic seizure can be predicted several dozens of minutes in advance, and the electroencephalogram monitoring device and method have high clinical and practical significance.

Description

technical field [0001] The invention belongs to the technical field of medical electronics, and in particular relates to a method for predicting epileptic seizures based on a directional transfer function, which can be used in a scalp electroencephalograph or an embedded cortical electroencephalogram monitoring system. Background technique [0002] As a neurological disease, epilepsy affects 50 million people in the world, of which 9 million are in China, and the cost of epilepsy treatment is about 1.25 billion yuan per year. Due to the suddenness of epileptic seizures and the possibility of fainting at any time during epileptic seizures, in addition to financial burdens, severe epilepsy patients may also face restrictions on activities, such as driving, swimming, etc. In addition, epilepsy patients also face learning disabilities and Great danger of complications such as depression. [0003] Since the mechanism of epileptic seizures is still unclear, and the patient's epil...
