多参数电话线传输监护系统的研制

The Development of a Phoneline-Based Distant Multi Parameter Monitoring System

远程监护和家庭护理技术是远程医疗非常重要的一个研究领域，由于心脏病和高血压病发病时一般具有突发性和危险性的特点，因此一般将心电图和无创血压的远程监护和报警作为家庭监护的首选内容．论文所开发的远程医疗监护系统采用普通电话线作为传输介质，是一种集实时监测、诊断与急救指导、心脏保健为一体的新型院外监护系统．监护中心站通过电话线能同时对多达８位院外患者的心电（心律失常）、血压和体温进行在线、准实时和长期监测，因而既可用来作为院内监护的延续，也可用来协助门诊诊断不明原因的心悸、胸闷、胸痛和晕厥患者的病情；或用于急性心肌梗塞后，以及室性心律失常、高血压病等高危患者的检测和指导治疗．监护中心站采用Ｗｉｎ９ｘ 为系统平台，在开发中充分利用以ＣＯＭ 为基础的ＡｃｔｉｖｅＸ组件工具精心设计了通信模块、心律检测和心律异常分析模块，从而使系统不仅功能强大，而且获得了很好的鲁棒性．

Telemonitoring and home health care technique are both among the most important research areas in telemedicine. Because heart disease and high blood pressure disease are very dangerous and paroxysmal, telemonitoring and alarming for ECG wave and noninvasive blood pressure are just the most important applying domain. In this paper, the design of a phoneline based remote multi parameter care system that may combine real time monitoring and online guide for patients in danger is discussed. The central monitoring system coold be used to monitor up to eight patients` ECG, blood pressure and temperature through the phone line at the same time .The whole system may be used for the extending ICU/CCU outside hospital, corporating with the clinic to diagnose unreasoned palpitations, chest pain and syncope, as well as for monitoring and curing guide for highly dangerous patients with abnormal heart rhythm and high blood pressure. The central monitoring system is designed on Win9x OS, and because of the thorough use of the ActiveX controls which are based on the COM Model to design the communication module, the HR check module and the abnormal heart rhythm check module, the system is not only outstanding but robust also.
