So, the principle of hemodialysis you know? Principle hemodialysis using dialysis membrane dialyzer semipermeable, by convection, diffusion, ultrafiltration and other physical phenomena, to make selective blood and dialysate ion components filtered, so as to achieve the purpose of dialysis.

Dialysis membrane is a hollow fiber, can acetate membrane, blood imitation film, polysulfone film material made of copper ammonium film, it can be all by water molecules, dialysate potassium, sodium, calcium and magnesium ions, single to pass the blood uric acid, urea, creatinine and other small molecules. For large molecular weight, such as blood cells, protein, fat molecules completely blocked.

Equipment and materials required for the configuration of hemodialysis water treatment machines, dialysis machines, dialyzers, needle, trail tube, saline, heparin, disinfectant and so on.
