Design and manufacture of prototype of facial shield with a respirator to avoid the spread of covid-19 (1st phase)

Abstract

Throughout 2020, the world has suffered the ravages of a coronavirus disease pandemic, started in 2019 (COVID-19) and caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In Peru, compulsory social isolation has generated great economic losses, which have resulted in job losses. The lack of adequate sanitary protection equipment that provides safe physical isolation conditions makes it difficult to return to a “normal state” of the productive apparatus. Based on this problem, the Center for Studies for Healthy Communities of the Ricardo Palma University, set out to design and manufacture a Prototype of a Face Shield with Respirator that prevents the spread of COVID-19. Based on previously published information and technologies available in our country, a practical solution was proposed to avoid the spread of the virus. The face shield has an electronicdigital system with proximity sensors (HC-SR04) to detect the approach within a radius of 1.5 meters, and MLX90614 temperature sensors to detect if the user has a temperature higher than 37.5 ° C. To view the user’s temperature data, the Face Shield has an OLED Module. All the information collected by the sensors is identified by the NodeMCU ESP8266 microcontroller, and the Arduino Nano V3 as the controller in charge of receiving the proximity sensors, communicated in a Serial (Tx / Rx) manner.
