【摘要】 随着经济的发展,生活节奏的加快以及全球老龄化的不断加剧,人们对医疗、健康、生活质量、疾病护理等方面提出了越来越高的要求。现代医学中,使用多生理参数监护仪,对人体生命体征进行长时间、连续的实时监控,可以及时了解病人的心肺功能及氧合能力等生理状态的变化,为临床诊断治疗提供重要可靠的信息。目前,市场上价格昂贵,操作复杂的高端监护设备和基于单片机、功能简单的低端监测设备都不能满足人们对高层次医疗保健和日常监护的需求。因此,对于能满足这种需求的便携式、智能化的多生理参数监护装置的研究具有重要的意义和巨大的市场前景。本文提出一种基于ARM的便携式多生理参数监护装置的研制方案。系统采用模块化的设计方案,以Cirrus Logical高集成ARM9微处理器EP9315为硬件平台核心,配合相应的生理信号采集模块,完成对心电、呼吸、血压、血氧、脉搏等生理参数的监测。该监护装置的主机操作系统采用嵌入式linux,利用Qt/Embedded完成嵌入式GUI监护界面开发,利用VS2010完成PC机上多参数监护应用程序的开发。同时,通过ARM微处理器的外设RS232串口实现监护装置与PC机的通信。本文详细论述了基于ARM的便携式多生理参数监护装置的硬件平台以及软件系统的设计和实现。经测试,该监护装置能够完成多生理参数的监测,同时整个装置具有体积小、功能强等特点,为进一步的产品开发打下基础。更多还原

【Abstract】 With the development of economy, life rhythm speeding up and the increasing of global aging, people raise higher requirements toward to medical treatment, health care, life quality, disease nursing etc. In modern medicine, using multi-parameter physiological monitoring equipment to monitor human life signs for long periods, continuous real-time monitoring, can learn about the patient’s cardiopulmonary function and oxygenation ability of physiological characteristic changes in time, which can provide vital reliable information for clinical diagnosis and treatment.At present, the expensive, complexly-operated of high-end monitor and based on MCU, function limited low-end monitor can not satisfy people the needs of medical care and daily monitoring. So, the research on a portable, intelligent and multi-parameter physiological monitor to meet those needs is of great significance and has the huge market prospect.This thesis proposed a development scheme on a kind of portable multi-parameter physiological monitoring device based on ARM. We adopted the modularizing design; the system using the high intergration ARM9 microprocessor EP9315 of Cirrus Logical hardware platform as a core, with corresponding physiological signal acquisition module to complete the monitoring physiological parameters of ECG, respiration, blood pressure ,oxygen saturation, pulse and so on. The host device operating system is embedded linux; Qt/Embedded interface development tools are used to design GUI monitoring interface, and VS2010 is used to complete the PC monitoring application development. Meanwhile,the communication between device and PC through the serial interface of ARM microprcessor peripherals RS232.This article discussed the hardware platform and software of the system design and implementation in detail. The test showed, the device can accomplish multiple physiological parameters monitoring.While the miniaturization and strong function laid the solid foundation for the further development and application.更多还原
