The Hygienic Chain — a holistic approach to optimizing dialysis fluid purity. Maintaining fluid purity means attending to the entire chain of components and processes involved in HD—from water treatment and concentrates to fluid distribution and HD machines. We call this chain: The Hygienic Chain. And like any chain, it is only as strong as its weakest link. This has never been more true than in the prevention of biofilm. That is why Gambro has designed an entire HD system to ensure optimal care while protecting your patients from the hazards of biofilm every step of the way. From water treatment and tubing to HD machines and concentrates, Gambro offers a fully integrated solution.
