Dear friends,
what we designed all together is not a medical device.
It is just a simple way to use a sport device commercialized by Decathlon ( hoping that it
can be purchased and modified all around the world) during this medical emergency, as arespirator ; the designed components, to be assembled on the original mask, can be 3d
printed everywhere.
The basic idea, coming from Dott. Renato Favero, to use the mask as a respirator was reallyingenious.
We simply made our best to fight against Covid19 all together.
We are grateful to Dott. Francesco Minardi, Dott. Luciano Bortone and to the Azienda
Ospedaliero - Universitaria di Parma.

Assembly instructions- MembraneThis membrane has to be demounted
and switched from outside the mask to
inside the mask. It is a safety valve
during air inspiration.

These 2 membranes are not neededto be demounted from the mask. Oneof these has to mounted in the nonreturn valve. (as described in the nextslides)7
