AN EMERGENCY VENTILATOR
Why it is needed
This is a worldwide effort where dozens of organizations and companies are working in parallel paths, with the unified goal of creating ventilators for the expected, unprecedented shortage of supply. Whoever solves this need can save lives and it doesn’t need to be our concept, but we’re working together to promote whatever can get there safely, the fastest.
AN EMERGENCY VENTILATOR
How it works
Our device is an assisted breathing device. It uses pressure to switch modes, so it really responds well to both assisted and automatic breathing. It can do more or less based on someone’s own capabilities. If someone tries to inhale, then it will help them inhale. If they try to exhale, then it will try to help them.
The pressure builds on both sides of the bistable fluidic amplifier to determine when to switch….so when the lungs fill up, the device switches to the other side and helps exhale. And when lungs get too low, the device air stream switches to the other side and helps inhale, all while keeping a positive pressure throughout. The 3 knobs on the device set the inhale pressure, the exhale pressure, and the duration of the exhale volume.
AN EMERGENCY VENTILATOR
Inspiration
The US Army came up with an emergency ventilator in 1965 in collaboration with Harry Diamond, and published a positive study of the outcome. Our concept builds on their innovative work.
Fresh Consulting and a team of innovators have come together to replicate that concept…and position it to scale after validating it meets safety standards and requirements.

Process
Our team is continuing to design, engineer and prototype and test ventilator concepts with standard hospital tube sizes. Our concept builds on their innovative work in fluid dynamics, but adds pressure adjustments on inhale and exhale. A team of innovators connected to Fresh Consulting have come together to replicate that concept…and position it to scale after validating it meets safety standards and requirements.
