基于阻抗测量与蓝牙技术的水肿监护系统的研制

Development of Edema Monitoring System Based on Impedance Measurement and Bluetooth Technology

人体水肿通常能够预示多种内部的疾病,如高血压、糖尿病、充血性心脏病等。本文介绍了一种实时监护身体健康状态(尤其是老年人)的水肿监护系统的设计。系统采用四电极测量法测量人体阻抗,通过人体阻抗值评估人体水肿状态,从而达到间接监护人体健康的目的;采用蓝牙4.0低功耗无线技术,将采集、分析、处理过的相关数据实时传送、显示、存储到移动电子设备(如智能手机)。与临床系统相比,该水肿监护系统具有便携、实时的优势。

Human body edema can often indicate a variety of internal diseases, such as high blood pressure, diabetes, congestive heart. In this paper, the design of an edema monitoring system used to monitor health condition（especially the elderly） in real time is introduced. The system adopts four electrode method to measure body impedance, and assesses human body edema state through the body impedance values, such monitoring the state of human health indirectly. The system collects, analyzes and processes the relevant data, and then transmits, displays, stores them to mobile electronic devices（such as smart phones） in time. Compared with the clinical system, the edema monitoring system has the advantages of being portable and real-time.
