Artificial respiratory system

I made this in a hurry for anyone who will need during those hard time a respiratory system

All parts can be 3d printed no matter the plastic, everything can be fitted together with glue and wooden screws, bolt and nut.

Be creative in the way you assemble the pieces together, look how it is builded in the pictures, you will understand how it work.

The green parts that block the air need to have a spring under it to make it work better, any pencil spring can be used on this, only one is essential in the inlet air on the piston.

Can be fully printed on a printer that can make 120 mm / 120 mm / 120 mm

A dc motor can be mounted, it's better to have a voltage regulation, the goal is to have a good rythm in the air flow
This machine push air and can extract it too without making it go back in again.

It look rudimentary but it work, i haven't time to publish anything else on it, hope it save someone life on the world.

Everyparts name have the number of times it need to be printed.
