Embodiment Construction

[0024] Such as figure 1 As shown, a closed-loop system for epilepsy treatment of the present invention is tested on an epilepsy model, including an EEG signal amplification module, a control unit, a stimulation module, and a video module; The EEG signal is judged by the control unit to determine the state of the EEG signal, and the stimulation module is controlled to generate a pulse current to stimulate the measured object.

[0025] EEG signal amplification module: multi-channel parallel acquisition and amplification of epileptic EEG ECoG signals.

[0026] Video module: collect video of the tested object and record the form of epileptic seizures.

[0027] Control unit: The functional requirements of the control unit are divided into 4 modules: display waveform module, parameter setting module, epilepsy early warning module and stimulation control module. The key module is the display of waveform. Read and analyze the data packets in the computer, and on the other hand, it i...

Abstract

The invention discloses a closed-loop system used for epilepsy treatment. The closed-loop system includes an electroencephalogram signal amplification module, a control unit, a stimulation module and a video module, wherein the electroencephalogram signal amplification module is used for collecting an electroencephalogram signal of a target to be detected; the state of the electroencephalogram signal is judged by the control unit, and the control unit controls the stimulation module to generate pulse current to stimulate the target to be detected to restrain epileptic seizure and further, closed loop regulation and control can be realized. The closed-loop system has the following functions: multichannel data with high sampling frequency can be obtained in a real-time manner through an amplifier, real-time drawing is carried out, epilepsy early warning is realized based on electroencephalogram signals, and epilepsy can be automatically restrained through electrostimulation with designated parameters after early warning. The invention provides a close-loop electrostimulation treatment system for patients suffering from intractable epilepsy, and the closed-loop system effectively reduces frequency of epileptic seizure, alleviates the intensity of epileptic seizure, and improves the living quality of patients.

Description

technical field [0001] The invention belongs to the technical fields of clinical medicine and nervous system, and in particular relates to a closed-loop system for treating epilepsy. Background technique [0002] Epilepsy is a common and multiple chronic neurological disease, which can cause motor, sensory, consciousness, and behavioral dysfunction, seriously affecting the work and life of patients, and bringing great mental and economic burdens to families and society. There are nearly 10 million epilepsy patients in my country, 20% of whom are refractory epilepsy. Half of intractable epilepsy can be treated surgically, and for patients with drug-refractory epilepsy who are not suitable for surgery or cannot receive surgery, electrical stimulation therapy may control and reduce seizures. [0003] Among the many electrical stimulation methods, a closed-loop reactive electrical stimulation technology is becoming a hot spot in the research of epilepsy diagnosis and treatment ...
