【摘要】：当前，，以高血压和冠心病为代表的心血管疾病，正日益成为人类健康的首要威胁。同时，飞速发展的无线网络通信技术，已经引发了一场新的信息化革命。以此为契机，以专业医院为主体的旧有医疗模式，正在向以社区和家庭为主的开放式新型医疗模式转换。在这种形势下，研究和开发以无线移动式平台作为医学信息载体，针对多种人体生理参数，实现健康和疾病诊断的便携式、智能化监测仪器系统，可以为心血管疾病的早期诊断和预防，提供全面、快捷的解决方案。人体生理参数主要包括心电、心率、血压、血氧和体温等。心脏作为人体血液循环的动力器官，以心动周期为节拍，重复完成心室的收缩和舒张过程。目前临床使用的心电ECG检查和动态心电监测（Holter），使用的均是氯化银（AgCl）湿性电极，它通过电解液凝胶体与皮肤接触来传导微弱的心电信号，但其毒性物质会渗透到皮肤中造成过敏性皮炎，而且在长时间使用后，电解液凝胶体因脱水而干化，造成电极与皮肤之间的接触阻抗发生变化，导致信号灵敏度和信噪比下降。此外，基于柯氏音听诊法的袖带充气式血压测量，除了束缚使用者的日常活动以外，当压力袖带工作时，会对患者造成突然性刺激，由心理变化产生情绪波动，导致测量结果失准。针对以上问题，论文以生命科学、计算机科学、现代通信技术和仪器科学为基础，研究了一种基于移动通信平台的人体生理参数监测系统，实现对心脏病和高血压等心血管疾病的早期诊断和预防。该系统由穿戴衣载体、纺织心电电极、指夹式脉搏波传感器及其测量电路，构成基本的心电和血氧饱和度的穿戴式测量单元，并通过对心电和脉搏波信号的波形参数进行回归计算，实现无袖带的收缩压和舒张压的动脉血压测量。另外，基于PDA构建了移动式用户手持终端，通过蓝牙接口，与测量单元构成人体躯域监测网络，完成心电和脉搏波数据的接收、波形回放显示，以及对血压和血氧饱和度等生理参数的计算。论文研究的主要内容包括： 1、完成系统总体结构设计。具体包括心电调理模块、血氧测量模块、微处理器单元、蓝牙传输模块的实现，并进行信号滤波电路的设计，有效地保证了后续信号的处理。 2、通过对移动终端的构建。实现人体心电和脉搏波数据的实时接收、波形回放显示，以及对血压和血氧饱和度等生理参数的计算。 3、实现了系统的软件设计。完成了用户手持终端的软件设计，通过设计数字滤波器，对心电信号进行了滤波处理。 4、进行血压和血氧饱和度的测量。通过对心电和脉搏波信号的波形参数进行回归计算，实现了无袖带的血压测量；针对监测系统的设计要求和血氧饱和度的测量状况，提出基于光谱监测原理来实现血氧饱和度的无创测量。 5、实验测试。应用监测系统进行实验分析。首先对测试者进行收缩压的参数标定，通过标定实验，证明了收缩压可以通过脉搏波传导时间直接近似计算；其次应用标准袖带血压计来对监测系统进行仪器的一致性分析，实验结果表明，使用该监测系统可以替代标准袖带血压计进行血压测量。
