Title:
ELECTROENCEPHALOGRAPH DEVICE AND SYSTEM, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/160557
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of electronic medical treatment, and provides an electroencephalograph device and system, a computer device, and a storage medium. The electroencephalograph device comprises: a stimulation unit for generating a stimulation signal; and an acquisition unit for acquiring physiological electrical signals of a human brain. The acquisition of the physiological electrical signals of the human brain by the acquisition unit comprises: when the stimulation unit does not apply the stimulation signal to a human body, the acquisition unit acquires physiological electrical signals of the human brain according to a first acquisition parameter; and when the stimulation unit applies the stimulation signal to the human body, the acquisition unit acquires physiological electrical signals of the human brain according to a second acquisition parameter, the first acquisition parameter being different from the second acquisition parameter. By using the technical solution of the present disclosure, the acquisition unit performs acquisition of the brain physiological electrical signals by using different acquisition parameters during stimulation and non-stimulation, so as to reduce the influence of aliasing noise and signal saturation on the acquired signals during stimulation, thereby acquiring effective electroencephalogram data.
