Portable Integrated Multi-Signal Patient Monitoring System

In this paper, we propose a stand-alone, embedded system design that integrates the monitoring of three biomedical parameters into a single personal medical device. The three parameters are: blood glucose level, heart rate, and pulse oximetry. The goal of this work is to build a compact and cost-effective device capable of monitoring several medical parameters while patients conduct their normal daily activities, and store these parameter readings in an embedded system-based portable device. The stored data can be later downloaded to a physician´s workstation and analyzed using a software application through the RS-232 communication interface
