本文介绍一种新型起搏系统——参数可调的埋藏式起搏器——的设计方案及实施技术.它由一个体外操纵器及一只带有数字记忆(由CMOS电路组成)元件的埋藏式起搏器所组成.无论在起搏器埋植前或后,当需要调节参数(包括接通或关断电源)时,可使用体外操纵器向起搏器发射一组编码的磁脉冲,这组脉冲被埋藏式起搏器感受,记忆,从而控制起搏参数到一新的指定的状态,并将这种状态一直保持下去直到进行再次调节. 由CMOS电路及混合型集成电路组成的起搏器具有功耗低、体积小、重量轻的特点.十个月的临床应用表明:调节灵活,性能可靠,疗效良好.
This article describes a new pacing system - a parametric adjustable buried pacemaker - designed and implemented by an in vitro manipulator and a digital memory (CMOS circuit components) buried Pacemaker. An external manipulator can be used to emit a coded set of magnetic pulses to the pacemaker, both before and after the pacemaker is implanted, when adjustments are required (including turning the power on or off) This set of impulses is sensed by the pacemaker and memorized to control the pacing parameters to a new specified state, and this state is maintained until further adjustments are made. The combination of CMOS and hybrid ICs The pacemaker has the characteristics of low power consumption, small volume and light weight, and ten months of clinical application shows that it has the advantages of flexible regulation, reliable performance and good curative effect.
