Classification of hemodialysis machines

- Dec 27, 2018-

Dialysis for medicine is broadly divided into two categories: hemodialysis and peritoneal dialysis


Hemodialysis is also known as artificial kidney and dialysis. It is a kind of blood purification technology. It utilizes the semi-permeable membrane principle to remove various harmful and redundant metabolic wastes and excessive electrolytes in the human body to purify the blood, and to achieve the purpose of correcting the balance of water electrolyte and acid-base.

Peritoneal dialysis

Peritoneal dialysis is to use peritoneum as a semi-permeable membrane, and the prepared dialysate is poured into the peritoneal cavity of the patient through the silicone catheter by gravity. Thus, there is a difference in the concentration gradient of the solute on both sides of the peritoneum. The solute on the high concentration side moves to the low concentration side (dispersion); the moisture moves from the hypotonic side to the hyperosmotic side (osmosis). Continuous replacement by abdominal dialysate. In order to achieve the purpose of eliminating metabolic products, toxic substances and correcting the imbalance of water and electrolyte balance.
