延长埋藏式起搏器的寿命和提高它的可靠性,是起搏器设计者的主要目标,也是医生和患者选择起搏器的主要依据,当然也要参照病情而考虑起搏器的功能。一、延长埋藏式起搏器寿命的途径“开源与节流”是延长埋藏式起搏器寿命的根本途径: 1.增加电池容量采用高能量密度、自放电小、搁置寿命长、具有全密封结构的高可靠锂系列电池,是延长起搏器寿命的主要方面。锂—碘电池、锂铬酸银电池、锂—硫化铜电池,经过十余年使用后,已被临床实践证明是高可靠长寿命的起搏器能源。它们的结构与电化学配比正向更合理的方向发展。由于结构的改进,使得新型锂电池的能量密度成倍增长,例如WGL755与WGL752尺寸基本相同,但是电池
Extending the life of an implanted pacemaker and increasing its reliability are the main goals of pacemakers and the primary basis for physicians and patients in choosing a pacemaker, and of course the pacemaker function in light of the condition. First, the way to extend the life of buried pacemaker “Open source and throttling” is to extend the life-long burial pacemaker fundamental way: 1. Increase the battery capacity with high energy density, small self-discharge, long shelf life, with a full seal Structure of high reliability lithium batteries, is to extend the life of the main aspects of pacemaker. Lithium-iodine batteries, lithium silver chromate batteries, lithium-copper sulfide batteries, after more than ten years of use, has been clinically proven to be reliable and long-term pacemaker energy. Their structure and electrochemical ratio is a more positive direction of development. Because of the structural improvement, the energy density of the new lithium battery is doubled. For example, the dimensions of the WGL755 and the WGL752 are basically the same, but the battery
