Research Of The Circuit For Implantable Neuromuscular Stimulation System

Functional Neuromuscular Stimulation in the treatment of nervous diseases and nerve injury rehabilitation function plays an important role. With the development of microelectronic technology, Micro-nano technology and bio-technology, Functional Neuromuscular Stimulation has been transformed the progressive development stage from a traditional transcutaneous electrical stimulation to implant electrical stimulation. Compared with transcutaneous electrical stimulation and implantable electrical stimulation, have outstanding advantages, stimulation accurate, stimulated current and sense of discomfort small. Control currently implanted nerve stimulator in the treatment of Parkinson's disease, epilepsy, chronic pain, incontinence, Audio Visual barriers has made substantial progress in many areas, and other issues such as spinal cord stimulation, electrical stimulation of gastrointestinal, and through electrical stimulation treatment of spastic, spasmodic torticollis, senile dementia. and other analgesic drug also has tempting prospect.In this paper, in Chongqing Municipality research project (Project No. : 7768) support, micro-implanted nerve stimulator system based on Zigbee Circuit of implanted nerve stimulator system. Implanted electrical nerve stimulation technology in the analysis. particularly wireless implanted nerve stimulator control circuit on the basis of the status quo at home and abroad. Zigbee wireless communication protocol combining the features of the system circuit for key technologies. developed to meet the requirements of the implanted nerve stimulator pulse circuit and two-way communication. Main thesis is :1. In an extensive literature on the basis of analysis of neuromuscular electrical stimulation device implanted in the development status and trends, Comparison implanted neuromuscular stimulation circuit characteristics of the circuit to determine the papers.2. Analysis of the implanted neuromuscular stimulation circuit characteristics and requirements neuromuscular electrical stimulation device implanted aimed at low power and control signals required for the signal control circuit research.3. Against implanted neuromuscular stimulation circuit miniaturization, low-power characteristics, is a flexible network topology. The ultra low-power short-range wireless communications Zigbee communication protocol to the agreement, as this paper. The software and hardware of communication module is designed.4. According implanted neuromuscular electrical stimulation pulse, Current research is a two-way miniature low power FES stimulation pulse output signal circuits.5. Integrated circuit modules of the system to the above, and the corresponding function test analysis.6. For neuromuscular electrical stimulation device implanted in the animal circuit verification experiment.
