Avoiding Toxicity From Water

Water is necessary for all hemodialysis treatments However drinking water contains a range of substances that are toxic to patients on hemodialysis Thus all dialysis facilities are equipped with a water treatment system that removes those substances from the water before it is used to prepare dialysate Increased demand for water and ever-evolving drinking water regulations are leading to

21 CFR 876 5665

A water purification system for hemodialysis is a device that is intended for use with a hemodialysis system and that is intended to remove organic and inorganic substances and microbial contaminants from water used to dilute dialysate concentrate to form dialysate This generic type of device may include a water softener sediment filter carbon filter and water distillation system (b

Dialysis Tubing

It is used in dialysis a process which involves the removal of very small molecular weight solutes from a solution along with equilibrating the solution in a new buffer This can also be useful for concentrating a dilute solution The tubing comes in variable dimensions and a range of molecular weight cut-offs (MWCOs) MWCOs designate a molecular weight below which molecules can move freely
