摘要
目的:研制一种无创式微型动态血压监护仪。方法:以一片80c196单片机和一个高分辨率液晶显示器(LCD)为基础,采用振动法原理和数据处理技术实现血压参数的实时检测和显示。结果:系统可动态实时显示所采集的血压波形和检测参数,并可存储显示24h内的血压数据信号,通过RS232接口可完成与计算机之间的数据通讯。结论:该仪器小型轻便,使用灵活,有较强的抗干扰能力,具有很大的应用价值。
AIM:To develop a non-invasive portable monitor for accurate dynamic blood pre ssure(BP) measurement. METHODS:With a piece of 80c196 singlechip and a high-differentiation LCD,a ne w portable monitor could carry out real-time examination and display of BP para meters on the basis of oscillometric method theory and data processing technique . RESULTS:System could dynamically show real-time BP wave shape and parameters, which then stored in computer for 24 hours for inter-computer communication thr ough RS232 interface. CONCLUSION:This kind of sphygmomanometer was of great applicable value because of mini-type and portability,as well as agile usage and anti-interference cap ability.
