Abstract: Dialysis machines comprising a feed arrangement to supply a dialysis fluid to a dialyzer during dialysis treatment and a return arrangement to remove the dialysis fluid from the dialyzer during dialysis treatment and forward it to an exit; a feed recirculation circuit to allow a fluid of the feed arrangement to be re-circulated in a fluid loop path comprising, at least a portion of, the feed arrangement and the feed recirculation circuit and a return recirculation circuit to allow a fluid of the return arrangement to re-circulate in an auxiliary fluid loop path comprising, at least a portion of, the return arrangement and the return recirculation circuit. A controller configured to perform disinfection by re-circulating a disinfectant and/or a heated fluid through said fluid loop path and/or through said auxiliary fluid loop path.

Abstract: System employing a sterile medical solution containing glucose or glucose polymers, for example nutritional solutions or solutions for peritoneal dialysis, whereby the majority of the solution is packed in a first package, while the glucose or the glucose polymers are separately packed in a second package, whereafter the two packages are heat sterilized. The content of the glucose or glucose polymers in the second package is maintained above 10% by weight, preferably above 20% by weight and most preferably in the order of 40% by weight in order to reduce or totally eliminate the breakdown of glucose. The medical solution after sterilization, mixing and diluting to 1.5% glucose content has an absorbency caused by breakdown products from glucose at 228 nm less than 0.35 and preferably in the order of 0.20 or lower. The medical solution is also defined in that after sterilization, mixing and dilution to 1.
