feedback welcome

I have no access to medical equipment, so I’ve designed this blind, if you have information or suggestions for improvement please let me know and I will update / re-release.

This is unprinted as yet.

Please use medical or food grade for printing, but whatever you have to hand may be needed.

I’ve used similar methods for printing female ports at the base, but this is the first Male at the base.

This is 100% open source – use it if its good for you, redesign, remix, change sizes, modify or ask if I can modify for you, I’ll help if I can.

UNTESTED.

UK Gov has fecked up and I’m hoping we can stop their negligence becoming a catastrophe. Here’s their guidance.

Based on an idea discussed in this academic paper

https://www.researchgate.net/publication/274750470_Experimental_3D_Printed_4-Port_Ventilator_Manifold_for_Potential_Use_in_Disaster_Surges

by Richard Siderits and Gregory Neyman of Robert Wood Johnson University Hospital, Hamilton, USA.

https://www.sciencedirect.com/science/article/pii/S0300957207005825 – Adult Sheep were put on a single ventilator with similar designs.

This is designed to require NO SUPPORT MATERIAL, MINIMAL FINISHING, BETTER CIRCULAR SECTIONS, FASTER PRINT TIMES.
