I'm curious about their dialysis system. I'm presently on dialysis myself. Some of the technology is straightforward. Its mostly making sure everything is sterile or you get a massive infection. The simplest technology is literally a bad of sugar solution that is fed by gravity and a second bag to drain out the solution. No power needed except to heat the solution to body temperature but you can manage without heating in a pinch. Again it all has to be super sterile so lots of one time use of plastics.
