Portable closed-loop brain deep part stimulator system with intelligent adaptive function

Abstract

The invention belongs to the field of medical clinical technology, and particularly relates to a portable closed-loop brain deep part stimulator system with an intelligent adaptive function. The system is provided with 16 data acquisition channels and 4 stimulation channels. Four acquisition channels in the 16 data acquisition channels are used for encephalic LFPs acquisition, and 12 acquisition channels are used for extracranial signal acquisition. The output voltage of the stimulation channel has a modulable random waveform. In recording, stimulation is performed, thereby effectively reducing influence of a stimulus artifact to a recording signal and realizing stable driving voltage. The system circuit mainly comprises an MCU master control circuit, an LFPs acquisition channel, an external acquisition channel switch circuit, a low-amplitude voltage insulating input circuit, a low-pass filtering unit, a high-pass filtering unit, an industrial frequency filtering unit, an A/D conversion acquisition circuit, a WIFI communication unit, a four-channel output D/A circuit, a voltage isolating output driving circuit, a current detecting protecting circuit, an SD storing unit, etc. The portable closed-loop brain deep part stimulator system has advantages of compact structure, low power consumption, high working stability, small system size which is approximate to that of a palm, and high convenience in carrying.

Description

technical field [0001] The invention belongs to the field of medical clinical technology, and in particular relates to a portable closed-loop deep brain stimulator system (IDBS) with an intelligent self-adaptive function. Background technique [0002] In recent years, deep brain stimulation therapy has become more and more widely used clinically, and it has become a treatment for Parkinson's disease, dystonia, epilepsy, tremor and other diseases, as well as pain and some mental diseases. Due to the advantages of non-destructive, micro-injury, recoverable and adjustable, deep brain stimulators have become the first choice for surgical treatment of PD diseases. [0003] Closed-loop deep brain stimulation treatment methods have received extensive attention and clinical research in the medical field. At present, compared with other treatment methods, such as drug therapy, deep brain stimulation devices have obvious advantages, such as less damage to cell tissue and fewer complic...
