摘要：

針對(duì)現(xiàn)有人工肛門(mén)括約肌系統(tǒng)無(wú)供能裝置或供能裝置更換可能引發(fā)感染等問(wèn)題，本文提出了電磁諧振耦合的無(wú)線供能方法，對(duì)人工肛門(mén)括約肌系統(tǒng)進(jìn)行非接觸的經(jīng)皮無(wú)線供能。本文在對(duì)能量傳輸電路、發(fā)送接收線圈參數(shù)研究基礎(chǔ)上，提出通過(guò)選擇SRC電路作為發(fā)射、接收端耦合電路以增大鐵芯耦合面積，從而提高發(fā)射及接收線圈Q值，進(jìn)而提高能量傳輸效率。實(shí)驗(yàn)結(jié)果表明，使用G25磁芯線圈進(jìn)行電磁耦合，當(dāng)兩線圈軸向距離為10mm時(shí)，能量傳輸效率可高于60%，可保證人工肛門(mén)括約肌系統(tǒng)的正常工作。

In order to solve the problems from the energy supply in vivo and vitro of artificial anal sphincter system, such as no energy supply equipment or the infection caused by equipment replacement, a wireless transcutanous energy transfer system was developed based on the electromagnetic coupling theory. According to the research of the energy transfer circuit, sending and receiving coils, this study pointed out an efficient method for transmitting energy, which included using SRC circuit, enlarging coupling area of cores and raising the value of Q parameter. More than 60% of transmission efficiency can be steadily received with G25 cores by electromagnetic coupling in the experiments at the axial separation of 10mm, which would guarantee the normal work of artificial anal sphincter.
