应用于蝶腭神经节电刺激的耦合线圈设计
Coupling coil design for electrical stimulation of sphenopalatine nerve
摘要
Abstract
In response to the therapeutic challenges of Acute Ischemic Stroke(AIS),a wireless power supply system for sphenopalatine ganglion electrical stimulation has been designed to address the limitations of traditional treatment.By employing near-field magnetic resonance coupling technology and an S-S topology with constant current characteristics,a stable current supply is provided.To ensure stable transmission at a constant frequency,the coil coupling is controlled near the critical coupling point to suppress the frequency splitting effect.The system uses a receiving coil with a diameter of 10 mm,achieving a Power Transfer Efficiency(PTE)of 25%in air and 12%in biological tissue,and maintaining over 90%of the alignment efficiency when the receiving coil deviates from the center of the transmitting coil by 5 mm,demonstrating good misalignment tolerance.This innovative solution is expected to meet the power supply needs of sphenopalatine ganglion electrical stimulation instruments,offering new possibilities for the treatment of AIS.关键词
