Portable Patient Vitals Monitoring Device

Abstract

The increasing demand for comprehensive and continuous health monitoring has led to the development of advanced portable medical devices. This paper presents a Portable Patient Vitals Monitoring Device with Integrated Non-Invasive Blood Pressure (NIBP) Measurement, capable of monitoring multiple physiological parameters in real time. The proposed system integrates biomedical sensors including a pulse sensor, ECG sensor, DHT11 sensor, and an NIBP module to measure heart rate, cardiac activity, environmental conditions, and blood pressure (systolic and diastolic). An ESP32 microcontroller is used as the main processing unit to acquire, analyze, and display the sensor data on an LCD screen. The NIBP module operates using the oscillometric method, where an air pump inflates the cuff and a pressure sensor detects arterial oscillations to determine blood pressure values. The system also incorporates a buzzer for immediate local alerts during abnormal conditions. For remote emergency response, an Arduino Nano interfaced with GPS and GSM modules transmits the patient’s health status along with real-time location via SMS to caregivers or medical professionals. Experimental results demonstrate that the system effectively monitors multiple vital parameters and provides timely alerts with location tracking. The integration of blood pressure measurement enhances the reliability and completeness of the monitoring system. The proposed device is portable, cost-effective, and suitable for home healthcare, elderly monitoring, and remote medical assistance, thereby improving patient safety and reducing response time during critical situations.
