Covid 19 Ventilator medical air-pump

I share my ventilator concept with you all, hoping it can save lives. It's a concept using a double-action manual pump with high air volume, similar to those used for inflating tents and inflatable beds worldwide in large volumes, making them easily accessible. This pump is paired with a linear stepper motor connected to the pump handle and performs the pumping action. The advantage of this double-action pump is that the air outlet is always under positive pressure, while the air inlet is under negative pressure in both pumping directions. Air flow and volume are controlled by an electric controller similar to those used for 3D printing, which sends movement speed information to the linear motor to mimic patient breathing rhythms. An Android app specifically developed for this pump could serve as an interface with the controller to adjust pump parameters. Multiple safety features include volume and pressure sensors, valves, and filters in addition to the system. My design is open source; if you see potential, use it and adapt it to your needs.
