Development Of Protable Multi-Parameter Physiological Monitoring Device Based On Arm

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.
