This is a short demo of the 3d printed, disposable ventilator. It’s a result of a 5 day design sprint we have done with my son Michael.
We have reviewed tons of existing designs, but none of them satisfied our timeline (two weeks to deliver 500 units) plus almost all of them required electronics which is impossible to design, make, troubleshoot and verify in such a short period of time. We were not happy with contamination protection and reliability of those designs.
We turned out attention to an old technology called bistable fluidic oscillators. These are aerodynamic devices with no moving parts which can perform pretty complex pneumatic operations. They are perfect for 3d printing too.
What you see is a Pressure Assist ventilator with a fall back respiratory rate. EIP is adjustable between 0 and 50 cm H2O and EEP between -4 and 20 cmH2O. RR can be tuned up, but for each patient the range will be different. To my knowledge, this is the only fully 3d printable, disposable ventilator. Perfect for disaster-relief type of work. Keep in mind that it has no FDA clearance and you have to consult your local regulatory bodies for guidance.
We are looking for collaborators. MDs who can advise us on possible applications, write clinical considerations, etc. Stay safe brothers and sisters. It will be an open source device. Our gift for you.
Please spread the word!

This clip shows how the ventilator follows the patient breathing (simulated by squeezing the test lung) and when patient stops breathing it returns to a fixed respiratory rate.
