Embodiment Construction

[0055] The technical solution of the present invention will be described below by taking an integrated closed-loop deep brain stimulator based on sleep detection as an example. Those skilled in the art can understand that embodiments of the present invention may also include other types of implanted medical devices, such as cardiac pacemakers, spinal cord stimulators, vagus nerve stimulators, and implanted drug pumps.

[0056] The deep brain stimulator includes a pulse generator, an extension wire, a stimulating electrode and the like. Among them, the pulse generator integrates a sleep detection module, a closed-loop control module, etc., and can realize the function of detecting the patient's sleep and adjusting the treatment plan accordingly without the need for equipment other than the pulse generator. The sleep detection module includes a signal sensing part and a signal preprocessing part. The closed-loop control module includes a sleep / wake recognition section and an ou...

Abstract

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.

Description

technical field [0001] The invention relates to a closed-loop control method for a deep brain stimulator, which is an integrated closed-loop deep brain stimulator that automatically and real-time adjusts stimulation parameters by identifying sleep and awakening. Background technique [0002] Implantable medical devices have become important therapeutic devices for patients suffering from neurological or psychiatric disorders. Technological advances in the field of neurostimulation make implantable medical devices promising. Implantable medical devices include deep brain stimulators (DBS) for Parkinson's disease, epilepsy, dystonia and other movement disorders, spinal cord stimulators (SCS) for pain, and epilepsy And depression vagus nerve stimulator (vagus nerve stimulator, VNS), and so on. [0003] Implantable medical devices treat neurological or psychiatric diseases by applying electrical stimulation to target nerves, generally including pulse generators, extension wire...
