Patient Bracelet Design for Monitoring Vitalsign SPO2, IoT based Heartrate and Temperature

Abstract

Vital sign examination is the most basic measurement of body function to determine clinical signs and is useful for strengthening the diagnosis of a disease and functions in determining the appropriate medical care plan. Oxygen saturation, heart rate and body temperature are some of the most basic vital sign parameters for paramedics in determining the physical condition of patients. The prototype designed aims to facilitate the measurement of heart rate, oxygen saturation and temperature with one tool. In using this tool requires a finger as the basis for taking heart rate data, oxygen saturation and wrist for temperature. To support data accuracy in patients, the author uses the MAX30102 sensor to measure heart rate, oxygen saturation, and body temperature using DS18B20. For the output display using TFT LCD and can display data in real time using the IP Address web based protocol, data retrieval is done by comparing the results of the module readings and comparison tools, namely pulse oxymetry with oxygen saturation and heart rate parameters. Testing is done using the fingertips as input for prototype sensor data, and temperature on the wrist. While the sensor data on pulse oxymetry is installed alternately in the same index finger position as the prototype sensor position. And for body temperature, data collection is done by comparing the reading results on the prototype with a digital thermometer. The results of the percentage of accuracy in testing using a pulse oxymetry comparison tool with oxygen saturation parameters (SpO2) of 99 %, the percentage of accuracy in the heart rate parameter (heartrate) of 97.99%, and the percentage of accuracy in the body temperature parameter of 97.75%.
