CoVent-19 Challenge

Our team has designed an electromechanical ventilator built around a customized bag-valve mask (BVM). We've distinguished our design from others that rely on BVM's by incorporating an independent, redundant bag as a safeguard in case of malfunction (motor/drive, rupture, failure to rebound, or unexpected movement). The system can detect failures through various pressure or flow sensors integrated into the setup. In the event of a breakdown, the ventilator can operate using a single bag. Utilizing two BVM's reduces cycle stress on silicone components, increases flow rates with shorter strokes, and enables constant positive pressure via computer control of cycling phases between drives.
