Abstract

The invention discloses a purifying column, device and method for purifying blood. An inner cavity of a columnar container in the purifying column is divided into a first space and a second space through a semipermeable membrane; agglutinin or a mixture formed by mixing heparin and agglutinin according to a preset proportion is treated as an adsorption medium to coat a solid substrate, and then the solid substrate is transferred into dialysate; the dialysate containing the adsorption medium flows in the same direction as blood in the first space and in the second space, and therefore the adsorption medium can effectively adsorb substances to be adsorbed (such as pathogens and tumor secretory protein) in the blood through the semipermeable membrane; and meanwhile, due to the fact that the dialysate containing the adsorption medium dynamically flows in the second space, after the dialysate is used for a long time and the adsorption medium loses efficacy, a dialysis column does not need to be replaced, and medical resources are saved.

Description

technical field [0001] The invention belongs to the technical field of hemodialysis, and in particular relates to a purification column, device and method for purifying blood. Background technique [0002] Hemodialysis (referred to as hemodialysis) is a kind of blood purification technology. The principle is: according to the principle of membrane balance, the patient's blood is passed through a membrane (or pipe, called a semi-permeable membrane in medicine) with many small holes. These small holes can allow molecules smaller than it to pass through, and the diameter is larger than the membrane hole. The molecules are prevented from remaining, and the semi-permeable membrane is in contact with the dialysate containing a certain chemical composition. [0003] On the basis of hemodialysis, some people have also proposed immune absorption technology to treat viral infections, adding adsorption media to the dialysate to remove pathogens in the blood. However, currently such pl...
