Instructables

Anybody want to model "reflux" in the circulatory system? Physical model or computer pipe model!

My wife just had an amazing success when we went down to Newport Beach, California to get venoplasty to relieve many of  her symptoms following a stroke.  http://www.youtube.com/playlist?list=PLkzXlmAwZTZfQ01RnN-8Ip5lUz0HrNWzN  We pay for national medical insurance in Canada and this treatment is not covered.  (Even though it clearly works, )   One road block is that an expert doctor here could not find any evidence of reflux in blood flow to or from the brain.  (Some MS patients have damaged valves in their neck veins).  Now, given that each heart beat raises blood pressure from 1.5 psi to 2.3  psi about once every second and that valves are actuated by the blood flowing backwards, I find the "expert doctor's" results impossible to believe.  I am not totally without knowlege in that area either because I made a low pressure airlift pump this year  that has a much higher lift submergence ratio than the normal ones.  (The airlift in a bucket one). I was told that the maximum  lift to submergence in these things was probably not much more that 10 to 1 but I managed to get over 20 to 1 lift to submergence primarly by reducing reflux.    Also, I observed that the effects of this reflux can extend conciderable distances from the "valve" itself and are different in small tubes than in big tubes.  Therefore it is possible (Likely even) that a damaged valve in a persons jugular will have its primary effect in a capallery somewhere in the brain up to a foot away from the damaged valve.  So if someone made this model, I think it is likely that they can contribute to the rapid advancement of medical science!   Brian White

I got a few replies in an engineering forum. CR4 in their bio-engineering section. Seems to be taboo here!  Such a shame.   Anyway, someone suggested that the valve thing could act by causing something like "water hammer" in the vascular system and another suggested it could cause non flow in certain capillaries with anoxic regions as a result. This would starve the brain of oxygen in those tiny regions. I also found a site with specific details about ms lesions that could  support my little theory OR the "water hammer" idea.   MS lesions have "localized mechanical damage!" There is Mechanical Damage to the blood vessels IN the lesions!  What can cause this damage to be so confined? I would love it if people would work with us. The info on the mechanical damage is at: http://www.ms-info.net/evo/msmanu/984 There is a whole book there if you like to learn.  I would find it absurd if wave dynamics that works in every fluid system in nature does not work in the human brain and its circulatory system.   I also find it absurd that people are not brave enough to comment.    MS hurts a lot of people.      Brian

Just been reading a link from Joan Beal. A professor in Austria notes that there is "mechanical damage" around MS lesions in the brain. This is entirely consistent with the theory I made up. The back of a vein valve when closed in the neck looks like a radio loudspeaker pointed upstream. At the point it closes, presumably the tissue of the valve flexes and sends a "pulse of waves" through the still blood and up into the brain. The pulse will stop when it resonates with the size of the blood vessel that carries it. Resonation may cause this mechanical damage! OR, it may split and take 2 pathways, depending on if the waves are in or out of sync when they rejoin, a lot of energy (shaking) can take place where they meet again.

Do you need more details before people comment? Imagine a pump sending liquid around a system with little tiny rubber pipes and tubes at one pump stroke per second. What effect does a leaky valve have BEHIND the valve and going back a ft into the little tubes? A damaged valve will send a little pressure wave back from the valve at each beat. You probably cannot see the pressure wave but you can set up a test to see how it gets dissipated. So you just run the experiment with a good valve in place, and with a damaged or no valve in place. You can use clear plastic tubes for convenience. You need some liquid with little lightweight particles or granules in it. Maybe old kidney dialysis tubes can be used among others because you have to have different sized tubes. If I visualize such a system at work, (when a faulty valve is in place, I can see a kind of harmonic system where the flow rates in the tubes are influenced by the damaged valve and the beat of the pump. In a normal person, perhaps the damaged valve does not matter so much because the heart rate is varying all the time. So the harmonics vary all the time. But many people with MS have a very stable heartbeat. This means that the harmonics are the same more or less all the time. So are areas of high pressure and areas of slow flow. This is really important because in MS the blood brain barrier is breached. You just need a modern camera on the experiment as you do it to see the effects as you vary the "heart beat". It is not that complicated but if any of you have seen my work, you will know I am not up to doing the experiment. thanks Brian.
