Perfluorocarbon emulsions are being clinically evaluated as artificial oxygen carriers ...ok...emulsions, got that right? US Patent #5,451,205 (issued September 19, 1995) LOL...what this Elsa? artificial induction of oxygene on transplants, and more...so emulsions on a shower head design basis? materials? check it out!

concept of ventilators (1)

what I think..what I bet is on new concepts..see this rain shower head? Both oxygene valves and involvement, both chemestry compounds..I'm trying to simplify the process...

wait a second, we are talking here...printing 3D the actual ventilator machine and then try to replace the high precisions instruments, it's not the right principle! If you renew and restart from the beggining you might hv a chance to cross trought the last generation of ventilators, but if you stuck on the basic of these one...you are not finding high precision to be massive product. Either you build a new concept..or you try Chemestry, basis.

can you print this...1st in plastic, and 2nd the robot frame in large scale?
