Description

Technical Field

[0001] The present invention relates to the technical field of dialysis machines, and in particular to a dialysis machine with blood oxygen saturation monitoring for use in plateau areas. Background Art

[0002] Hemodialysis, clinically, refers to the removal of some waste products from the blood through a semipermeable membrane. Hemodialysis is one of the safer, easier, and more widely used methods of blood purification. Dialysis refers to the movement of solutes from a high-concentration solution to a low-concentration solution through a semipermeable membrane. Hemodialysis involves the movement of solutes and water, that is, blood and dialysate exchange substances through the semipermeable membrane and concentration gradient within the dialyzer (artificial kidney), causing metabolic waste products and excess electrolytes in the blood to move into the dialysate, and calcium ions, bases, etc. in the dialysate to move into the blood. If a mixture of albumin and urea is placed in the dialyzer and the outside of the tube is soaked in water, the urea in the dialyzer tube will move through the pores of the artificial kidney membrane into the water outside the tube. Albumin molecules are larger and cannot pass through the membrane pores. This movement of small molecules that can pass through but large molecules that cannot pass through the semipermeable membrane is called diffusion. The clinical method of using diffusion to separate and purify blood to achieve the purpose of purification is the basic principle of hemodialysis.
