Neyman-Irvin Ventilator Manifold with Check Valves

thingiverse

Built a ventilator manifold that can support four individuals on a single ventilator in emergency situations, such as the COVID-19 pandemic. The manifolds feature integrated check valves designed to prevent cross-contamination and ensure adequate spacing for inline filters on the exhalation side. These check valves utilize 40mm ping-pong balls with a 20mm version currently under experimentation. This project remains a work-in-progress, yet its urgency demands immediate attention. Refer to the original study at https://onlinelibrary.wiley.com/doi/epdf/10.1197/j.aem.2006.05.009 for further information. A video explanation of this project is available at https://www.youtube.com/watch?v=uClq978oohY&t=5s. For those interested in acquiring the necessary ping-pong balls, 40mm versions can be found on Amazon at https://smile.amazon.com/Click-Play-Advanced-Training-Tournament/dp/B07JBJJN82/. The Prusa i3 Mk3S with 0.20mm PETG at 20% infill was used to test the manifold, with ongoing efforts to optimize clearances for various materials and printers. As of April 13, 2020, the 20mm version of the manifold has been removed due to consistency issues. A new design for the 40mm manifold has been implemented, significantly improving flow while slightly reducing print time.
