Inkjet Cartridges To Save Your KidneysSometimes it's hard to remember that inkjet printers are good for anything other than ripping you off, but news today from HP's own intellectual property czar may change that: the technology that regulates the precise mixture of pigments down to the last picoliter will soon make home kidney dialysis machines more accurate by regulating mixtures of dialysis fluid with similar accuracy. People with kidney problems often have to undergo dialysis treatments several times per day, so doing so at home is a necessity; unfortunately, home dialysis is prone to errors because the dialysis solution must be mixed precisely, often at varying concentrations. The HP-licensed inkjet tech will allow for dialysis solution to come in easy-to-swap cartridges that handle precise mixtures automatically. OK, you're off the hook for now, HP. For now. [CNET]
