摘要
研究了一种新的体外反搏充排气时序控制算法。采用ｐｅｎｔｉｕｍ 微机、十六位单片机并行中断通迅技术研制了一种新型体外反搏控制系统。十六位单片机完成心电信号，反搏波信号的采集和预处理。预处理后的数据经并行通迅接口传至上位机。由ｐｅｎｔｉｕｍ 微机根据所研究的控制算法完成反搏充、排气时序信号的控制及反搏状态监测。反搏系统严格保持反搏波传到主动脉瓣处与主动瓣脉关闭时刻同步，增强反搏器系统出错报警处理能力，在保障病人的安全条件下极大限度地提高反搏的疗效。
A new algorithm for the inflation and deflation timing of the Enhanced External Counterpulsation (EECP) have been developed, A pentium PC and 16 bit microcontroller with parallel interrupt communication were used for developing a new kind of EECP system.The 16 bit microcontroller was used to collect and pre-process the ECG and EECP signals.The pre-processing data is transmitted to PC by the parallel communication interface. According to the new algorithm, PC sent out the sequential control signals and monitor the state of EECP.It is necessary to synchronize the time of aortic valve closure and diastolic augmentation during EECP,under the condition of the patients' safety ,the effect of therapy have been extremely improved.
