Background

Hemodialysis, which is one of the safer, easier and widely used blood purification methods, is a process in which solutes move from a high-concentration solution to a low-concentration solution through a semipermeable membrane. Hemodialysis involves the movement of solutes and the movement of water, i.e., the exchange of substances between blood and dialysate in a dialyzer (artificial kidney) by means of semipermeable membrane contact and concentration gradients, causing metabolic wastes and excess electrolytes in the blood to move towards the dialysate, and calcium ions, bases, etc. in the dialysate to move towards the blood. If the mixed liquid of albumin and urea is put into a dialyzer and the outside of the dialyzer is soaked by water, the urea in the dialyzer tube can move to the water outside the dialyzer tube through the artificial kidney membrane pores, and albumin molecules are large and cannot pass through the membrane pores.
