Subject: Circulatory assist for perfusion


I thought I posted this around Oct 18th, but I
couldn't find it in the archives.  So here it is. 


While searching the CI website for other info, I came
across this article:

"Vitrification Protocol used on Dog" by Ben Best


In the article I note the use of an ACDC Thumper. 
Clearly, this is a mechanical means to assist in the
circulation of fluids in the vasculature -- to help
the distribution of perfusate in the various stages of

I'm wondering if other means have been
considered/evaluated.  Specifically:

"full- or half-leg pneumatic compression devices"
(Do a google search on the above term.)

For a patent application drawing of the device, here
is a US patent issued 1982


Then, along the same lines, I had another thought.
While it may seem odd, even humorous, I couldn't help
but think that a seemingly logical assist to the
circulatory process could be achieved simply by
strapping the patient to what would be essentially an
elevated see saw, and then cycling him/her between
head up and head down orientations.  One way valves in
the veins means that gravity-driven circulation or any
other kind for that matter) goes only one way, the
right way.

Or you could use the pneumatic leg compression and the
see saw simultaneously.

Very simple.  Very non invasive.

Just a thought. 

Best, Jeff Davis
