Electroencephalograph device and system, computer device, and storage medium

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.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/377, A61B5/4836, A61B5/7217, A61N1/36031, G06F3/015). The claims define what a patent protects, and they are not read here.

Signal acquisition

Neural signals are microvolts. They have to be amplified and digitised on many channels at once, inside a power budget that must not warm the tissue. The problem behind it: low noise on hundreds or thousands of channels at milliwatts.

Signal processing

A decoder is only as good as the features it is given, and recordings drift and pick up noise from movement, muscle and stimulation. The problem behind it: stable features from signals that change from day to day, computed fast enough to act on.

Stimulation

Restoring sensation, sight or movement needs information going in, and a therapy that adapts needs to sense and stimulate at once. The problem behind it: evoking a precise, stable effect without damaging tissue or electrodes, and without blinding the recording.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack
