| 摘 要： | 采用单片机研制了一种便携式生命参数监护仪，用于多种环境下监测人体心率、脉搏血氧饱和度、呼吸频率、无创血压及体温等基本生命参数。系统采用2片80C196KC作为数据采集、处理及控制的核心单元，采用液晶显示器显示，非易失RAM保存数据，并提供了RS232接口与计算机进行数据交换。实验样机能正确地完成各项生命参数的监测，性能稳定。系统充分利用了单片机的优势，仪器体积小，功耗低。实验表明该设计方案是可行的。

| Abstract: | A portable vital signs monitor is designed based on microprocessors to monitor heart rate,Spo2,breath rate,noninvasive blood pressure and body temperature of human in multi-environments.2chips of80C196KC serves as core unit to acquire,process,display and save data.LCD is used to display data,waveform and NVRAM is used to store data.The monitor has RS232interface with the PC to exchange data.Experiments show that the system can run stably and monitor vital signs of human accurately.Taking full advantage of the microprocessors,the system is of low consumption and can be made into small size.It is proved that the design of the monitor is practicable. |
