Wm.,
This stuff is different from what you think: the "crystals" are actually
the clotting components of blood. I think fibrin and something else.
It is not that the bandage makes the blood clot, it is that the
bandage is a clot waiting for some fluid to make it happen.
At one point they were also talking about making it in a can,
like shaving cream, or cheeze-wiz, with an applicator that you
stick right in the wound and squirt the stuff in.
The liver is so vascularized that trauma wounds there are almost
always fatal, since the rate of blood loss is so high.
Work with goats showed that traumatic liver injuries (basically
they shoot the goats) would heal in a month to the point that there
was no sign of the wound, external or internal.
But anyway, it works by actually clotting itself, it does not
work by generating heat and causing the blood to clot.
How about putting a heating element into the flat bed or carrier
that is fed through the printedr?
