RESEARCH ON DESIGNING THE VENTILATOR

Abstract

Ventilators are currently very focused on research and production to serve the treatment process for patients with respiratory difficulties and patients infected with the COVID-19 virus in particular. In this study, the ventilator is fabricated on the principles of conventional ventilators, but it is improved in a number of features to suit all subjects. The frequency of the ventilator can vary widely from 12 to 40 beats/min, and the maximum I:E ratio (equal 1: 4) is suitable for both normal and COVID-19 infected patients. Mechanically, the arm of the machine is simulated based on the human arm, the squeezing force comes from both sides of the Ambu ball so it does not deform much, and the squeezing speed of the machine is fast, which can adjust the amount of air provided to the patients. The ventilator in this study is integrated an extra heart-beat measuring sensor, which is useful for caring and supervising
patients. In addition, our ventilator uses the Arduino board as a central control unit, so it is easy to develop many new functions.
