Rapidly developable low cost and power efficient portable turbine-based emergency ventilator

Use of ventilators has always been common in medical scenarios but very expensive to procure or develop; mainly because of expensive components precise instrumentation. Our paper attempts to mitigate that problem by proposing a novel way to rapidly develop a low cost and power efficient portable turbine-based emergency ventilator that uses 3D printing technology and off-the-shelf components. This turbine and valve-based ventilator features most commonly used modes. A unique servo-based pressure release mechanism has been designed that makes the system around 36 times more efficient than solenoid-based systems. Reliability and efficiency have been increased further through the absence of electromechanical component in our novel positive end expiratory pressure (PEEP) valve. Effective algorithms such as feed-forward and PID are used alongside our unique ‘Sensor data filtration Methodology’. It provides an interactive GUI through an app that can be installed on any readily found tablets while the firmware manages the breathing detection algorithm using flow sensor. This modular, portable, energy-efficient and low-noise system ventilator also features swappable battery that can run for 5.6 hours at a stretch and also holds the ability to even run-on solar power.
