Design and Development of a Bracelet to Monitor Vital signs of COVID-19 Patients

COVID-19, which stands for Coronavirus disease 2019, is an infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first reported in December 2019 in Wuhan, China. The new coronavirus has spread rapidly around the world, causing extensive deaths, and turning into a new global public health crisis. This paper proposes a prototype system to assist medical staff in identifying and monitoring COVID-19 symptoms by measuring vital signs. This study aims to help prevent hospitalization of patients in the ICU by continuously monitoring the patient’s vital signs, which allows medical staff to diagnose the patient’s health at the appropriate time. The use of sensors has grown in many areas over the past decade, especially in wearable healthcare devices. In this paper, the hardware components, and the design structure of the bracelet have been presented. The bracelet is responsible for measuring and transferring vital signs like body temperature, oxygen saturation, and heart rate to the Base Control Unit. The Max 30100 and DS18B20 sensors are used to read the vital signs of the patient and transmit them to the microcontroller inside the bracelet. The microcontroller will send vital signs data to the Raspberry Pi to analyse, process, save, and display. The design and implementation of this bracelet have been done by developing a 3D printed model after examining several models on people of different ages.
