Past schemas & ideas

Three variants are considered, but currently we focus on the one closest to the requirement of medical staff.

Recovid-MD - has to be submitted to regulatory clinical tests before used as a medical device grade ventilator - In french

This is our current target (in english)

It is not clear if this type of device is of any use in a Hospital. No sensors, so no clinically usable data. recovid-giy

Scrap-made presure valves (APL, PEEP)

Material: aquarium tube 4mm internal / 6mm external Section not enough enough I would have to double the diameter 2 or 4 non-return valve: https://www.botanic.com/produit/366004/clapet-anti-retour-pour-pompe-a-air.html pipe 4/6mm : https://www.botanic.com/produit/365979/tuyau-pour-pompe-a-air-4-6mm-silicone-2-5m.html possibility of using diffusers in a volume of water to filter the exhaled air: https://www.botanic.com/produit/365998/diffuseur-aquarium-ceramique-50mm.html ISSUE:

  • the rectangular volumes prevent the water used for pressure control from leaving the system I still don't know how to make them.
  • the system is not adjustable in pressure ... except to put several PEP control system in parallel with small valves: not terrible
