Description

technical field

[0001] The invention relates to continuous arteriovenous hemodialysis / filtration equipment, in particular to a liquid balance liquid supply device and its application. Background technique

[0002] Continuous arterial-venous hemodialysis / filtration is a blood purification therapy that continuously replaces damaged kidney function, and it is a treatment method to achieve hemofiltration on the basis of hemodialysis.

[0003] Hemodialysis treatment is to pass blood through a dialyzer made of semipermeable membranes that can only allow small molecule substances (such as electrolytes, small molecule nephrotoxins, etc.), so that the blood is on one side of the membrane, and the replacement fluid is on the other side of the membrane. On the other side, the solutions on both sides go through diffusion and osmosis, that is, the solute permeates from the side with high concentration to the side with low concentration, allowing medium and small molecular toxins in the b...
