Sleep detection-based integrated closed loop deep brain stimulator
The invention provides a sleep detection-based integrated closed loop deep brain stimulator. The sleep detection-based integrated closed loop deep brain stimulator has a real-time sleep detection function, is capable of identifying the sleep or awake state of a patient and is capable of automatically adjustably outputting parameters of electrical stimulation in real time according to different states of the patient. When the patient is sleeping, a pulse generator automatically stops outputting the electrical stimulation or weakening the strength of the electrical stimulation output, and when the patient is awake, a normal operation mode of the pulse generator is recovered. On one hand, the system power consumption of the deep brain stimulator is favorably reduced, and thereby, the service life of the deep brain stimulator is prolonged, and on the other hand, the sleep detection-based integrated closed loop deep brain stimulator is favorable for reducing the harmful effects of the continuous high-frequency electrical simulation to the patient.
