The independent research and development of the pacemaker of Xi'an Jiaotong University has made progress

reporter recently held in Harbin City, the 13th China Heart Law Forum was informed that by Xi'an Jiaotong University Medical Electronic Engineering Research Institute and other units independently developed single-cavity bipolar 9-program SSIthe first batch of 1000 pacemakers and 100 program-controllers of the cardiacpacemaker has just entered the trial stage; The test results show that these pacemakers, developed by China, are better than similar products abroad in terms of power consumption,volume,anti-jamming,service life, etcPacemaker is amedical devicewith high clinical useOver the years, China's pacemakers mainly rely on imports, the cost of, highcosts, to many patients brought a heavy financial burdenIn the past two years, the national "863" program has increased the support for the development of domestic pacemakers, thus accelerating the independent research and development of pacemakers in ChinaAccording to Professor Jin Jie, Director of the Institute of Medical Electronic Engineering, Xi'an Jiaotong University School of Medicine, 2

, "Domestic implanted pacemaker series development" project was included in the national "863" program special project, the main goal is to achieve the institute and Shaanxi Qinming Company, in the core technology with China's independent intellectual property rights of the single-cavity bipolar 9-program SSI pacemaker industrialization , and developed a series of international-level implanted pacemakers According to the introduction , according to the number of electrode wires implanted in the heart cavity , pacemaker can be divided into single-cavity, double-cavity pacemaker This single-cavity bipolar 9-program-controlled SSI pacemaker uses a general-purpose microprocessor design than the customer's customized special circuit design with microprocessor core, the low cost of research and development , device reliability is guaranteed, the shutdown current is less than 1 microamps, in power consumption, volume and life expectancy have a certain advantage, suitable for China's national conditions The test results of the wireless communication supervision and inspection center of the ministry of information industry on the performance of the pacemaker anti-mobile communication interference show that the pacemaker has good anti-jamming ability for GPS and CDMA mobile phones; According to Professor Jin Jie, a series of new implanted pacemaker (
such as intelligent dual-cavity frequency-response pacemaker) special circuit pre-research, overall design and circuit module sample production, software and hardware design supporting program controller movement, dual-cavity pacemaker packaging process and supporting electrode design and sample production work has been completed The two-way data transmission of the new pacemaker and in vitro program controller uses RF field power supply and load modulation, does not consume internal battery energy, and is particularly suitable for smart two-cavity frequency-response pacemakers such as pacemakers with rich diagnostic functions THE NEW PROGRAM CONTROLLER USES A 3
