Examples of the implantable neural electrical Stimulation device include Deep Brain Stimulation (DBS), Cortical Brain Stimulation (CNS), Spinal Cord Stimulation (SCS), Sacral Nerve Stimulation (SNS), and Vagal Nerve Stimulation (VNS). Parameters of the stimulator are, for example, the frequency (number of pulses per unit time 1s, in Hz), the pulse width (duration of each pulse, in mus), and the amplitude (generally expressed in voltage, i.e. the intensity of each pulse, in V). In a particular application, the parameters of the stimulator may be adjusted in either current mode or voltage mode.

In the collecting process, the stimulator can obtain the real-time electroencephalogram signal corresponding to each moment, such as the real-time electroencephalogram signal at the previous moment, the real-time electroencephalogram signal at the current moment and the real-time electroencephalogram signal at the next moment.
In some embodiments, the method for acquiring real-time brain electrical signals of the patient by using the stimulator in the step S101 may include: and acquiring real-time electroencephalogram signals of the patient by using the stimulator at preset time or at preset time intervals.

Step S504: and when the feedback operation is a modification operation, modifying the parameter configuration information corresponding to the real-time state type in response to the modification operation, and adjusting the parameters of the stimulator by using the program control equipment based on the modified parameter configuration information.
Therefore, an adjustment request can be generated and sent to doctor equipment corresponding to a patient based on the parameter configuration information corresponding to the real-time state type, and a doctor determines whether to adjust the parameters of the stimulator by adopting the parameter configuration information; on the other hand, when the doctor considers that the parameter configuration information is not appropriate and needs to be modified, the parameter configuration information can be modified, and the parameters of the stimulator can be adjusted based on the modified parameter configuration information. The marking of the state type of the patient is generally completed by the patient or a person who cares for the patient, a condition of error marking may exist during marking, if the condition is not confirmed by a doctor, electrical stimulation is directly applied according to parameters corresponding to the condition type marked with the error, the patient may be injured, and the life may be damaged in serious conditions, so that feedback operation of the doctor is very necessary, the life safety of the patient can be guaranteed, and the doctor can know the condition change condition of the patient.
