Embodiment 1

[0065] figure 2 The processing flow of Embodiment 1 of the present invention is shown. In Embodiment 1, the acquisition unit adjusts the acquisition operation during the stimulation process and the non-stimulation process according to the pre-stored acquisition parameters. Correspondingly, the EEG device may further include a storage unit for storing the first acquisition parameter and the second acquisition parameter. In an optional implementation manner, the acquisition unit may include the storage unit.

[0066] In Embodiment 1, the processing of the EEG device may include:

[0067] S101. During the non-stimulation process without stimulation, the acquisition unit 102 collects the human body according to the first pre-stored acquisition parameters (for example, the sampling rate is 1 kHz (ie, the first acquisition frequency), and the gain is 100 times (ie, the first signal gain)). Physiological electrical signals of the brain.

[0068] S102, the collection unit 102 pre...

Embodiment 2

[0073] image 3 The processing flow of Embodiment 2 of the present invention is shown. The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the stimulation unit 101 actively initiates stimulation. Specifically, the processing of the EEG device may include:

[0074] S201. During the non-stimulation process without stimulation, the acquisition unit 102 collects the human body according to the first pre-stored acquisition parameters (for example, the sampling rate is 1 kHz (ie, the first acquisition frequency), and the gain is 100 times (ie, the first signal gain)). Physiological electrical signals of the brain.

[0075] S202 , the stimulation unit 101 starts a stimulation action, and notifies the collection unit 102 . The acquisition unit 102 adjusts the acquisition parameters to the second acquisition parameters after receiving the notification from the stimulation unit 101 to initiate stimulation, for example, the sampling rate is 16 kHz (ie, the se...

Embodiment 3

[0080] Figure 4 The processing flow of Embodiment 3 of the present invention is shown. In embodiment 3, the processing of the EEG device includes:

[0081] S301. During the non-stimulation process without stimulation, the acquisition unit 102 acquires the human brain according to the first acquisition parameters (for example, the sampling rate is 1 kHz (ie, the first acquisition frequency), and the gain is 100 times (ie, the first signal gain)). Physiological electrical signal.

[0082] S302, the acquisition unit 102 prepares to request the stimulation unit 101 to perform a stimulation action, and adjusts the acquisition frequency to the acquisition frequency of a second acquisition parameter different from the first acquisition parameter, for example, it may be the maximum value supported by the system of the EEG device. In an optional implementation manner, the collection frequency of the second collection parameter may also be other values ​​higher than the first collect...

Abstract

The invention relates to the technical field of electronic medical treatment, and provides an electroencephalogram device and system, a computer device and a storage medium. The electroencephalogram device comprises: a stimulation unit for generating a stimulation signal; and an acquisition unit for acquiring a human brain physiological electric signal, wherein the step of acquiring the human brain physiological electric signal by the acquisition unit comprises the following sub-steps: when the stimulation unit does not apply the stimulation signal to a human body, the human brain physiological electric signal is acquired by the acquisition unit according to a first acquisition parameter; in the process that the stimulation unit applies the stimulation signal to the human body, the acquisition unit acquires a human brain physiological electric signal according to the second acquisition parameter; the first acquisition parameter is different from the second acquisition parameter. By theadoption of the technical scheme, the acquisition unit collects the brain physiological electric signal through different collecting parameters in the stimulation process and the non-stimulation process so as to reduce the influence of aliasing noise and signal saturation on the collected signal in the stimulation process, and then effective electroencephalogram data can be collected.

Description

technical field [0001] The present invention relates to the technical field of electronic medical treatment, in particular, to an electroencephalogram device, system, computer device and storage medium. Background technique [0002] As one of the basic physiological signals of the human body, the physiological electrical signal of the brain has important reference value for clinical diagnosis and treatment. However, the non-stationary and random characteristics of brain physiological electrical signals determine that its research is quite difficult. [0003] As an important field of scientific research and medical treatment, electrical stimulation therapy also plays a very important role in the study of brain physiological electrical signals. It plays an important role in common diseases such as epilepsy by performing targeted, specific, and purposeful electrical stimulation on specific parts of the human body, and then analyzing it based on the feedback of EEG signals.
