Respirator-free reanimation Venturi's valve

You may have read my recent article explaining how Italian company Isinnova responded to a call for help from a hospital in Northern Italy to keep their reanimation devices operational during the Covid-19 pandemic by 3D printing replacement valves that had become unavailable from their usual suppliers.

These ready-to-print Venturi's valve models are for respirator-free masks and have been created as a non-profit project for the Covid-19 pandemic.

Revision 2 (CFD-calculated) available:

• FiO2 = ~33%
• O2 sup. = 10LPM
• Air out. = ~63LPM

2x 25mm O.D. (air suction, patient) 1x 5mm O.D. (oxygen)

Volume of 3D model - 15133 mm3

Revision 1 contains 3 Venturi Valves with: B = 0,12 ; 0,3 ; 0,5

You can download the 3D CAD files for these valves here in my3DPM, to ensure that everybody who needs access to them can print their own.
