Prototype of a Device for the Automatic Measurement of Physiological Signals to Assist the Diagnosis and Monitoring of Patients with Covid-19

ABSTRACT

This article describes the design, construction and preliminary results of a device to automate the mea-surement of physiological signals to assist in the diag-nosis and monitoring of COVID-19. The device uses a system to controlling linear actuators to turn on/off certified biomedical instruments, in addition to algo-rithms for image recognition of displays with measure-ments of temperature, oxygen saturation, pressure and heart rate. The system also includes a mobile ap-plication, which receives data in real time and creates a database for medical evaluation. Results obtained with the device have demonstrated to provide a high percentage of efficiency in the data acquisition. After several trials with users, SUS and PSSUQ tests were applied to allow verifying the users' feedback regard-ing the satisfaction and usability of the prototype, with high score, showing the good acceptance of the device from the users.
