Low Cost Locally Sourced Ventilator
On March 3rd 2020 Sai Ravela assembled a team to develop a design that is now under development for the production of ventilators. Our intent is a design that can be manufactured and deployed rapidly around the globe with Commercial Off The Shelf*, locally sourced components to help meet the challenge of the Covid-19 emergency.
- Design standards: UK Rapidly Manufactured Ventilator System Specification
- Aimed at patients entering the acute stage.
- Filtered, heated, and oxygen- and moisture-mixed air with tunable mixing ratio, flow rate, pressure and temperature.
- Air supply provided by compressor with 50psi line/15lts/min (included).Hospital lines can be connected.
- Oxygen provided by concentrator or tank. Hospital lines can be connected.
- We are presently working on low-cost concentrators
- All plug-to-connect pneumatic circuitry
- Air and virus filters, and water collectors standard
- Ardupilots repurposed for the embedded system.
- PWM servos (e.g. from hobby aircraft) drive low-cost proportional valve control.
- Wifi or LTE port to provide wide area or large-scale monitoring and setup respectively, and remote support.
- Sensing for static and dynamic pressure, temperature, humidity, concentration (optional). Spirometric synchronization.
- Hybrid technology: Uses physical principles and machine learning to derive amazing performance from generic components
- Maximally Commercial Off The Shelf (COTS) and locally sourced components for international version
- Robotic manufacture of kits for rapid, scalable, and cost-effective national outreach.
- 24/7 and emergency systems

We are in the prototyping stage. We anticipate field testing by April 15.
We aim to move from the prototype phase to a manufacturing process that is scalable. Mark 1 is for export (India is primary focus), Mark 2 for US.
*Parts Suppliers (to be completed):
Amazon.com -- various vendors therein. Some quality issues have remained, but amazing fast delivery (before delivery date)
Arrow Electronics -- all our chip level components
CPRSavers -- oxygen supplies
EPartsStore -- misc. medical tubing/pipes
ExpressPCB -- all our boards
Home Depot -- various tools, boxes, tubes,
Trimantec -- valves
Contact: we are working on this voluntarily in a perosnal capacity, and not as a part of MIT sponsored research.
