3D CAD File: Respirator-free reanimation Venturi's valveこの記事を購読
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.
Below we have included a link to download the 3D CAD files for these valves, to ensure that everybody who needs access to them can print their own.
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
Files Included: STL, STEP / IGES, Rendering, SOLIDWORKS
For anybody who needs access to a free 3D design software in order to access these files DesignSpark Mechanical is free to download and use for both personal and commercial use.
