Abstract

The invention provides a preparation method of broad-spectrum blood perfusion macroporous adsorption resin. The preparation method comprises the following steps: 1) a poly(styrene-divinylbenzene) polymerization step, 2) a step of preparing chloromethylated beads by a one-pot method, 3) a step of grafting the chloromethylated beads with functional groups, and 4) a post-treatment step. In the chloromethylation stage of poly(styrene-divinylbenzene), a one-pot method is adopted to prepare the chloromethylated beads, the poly(styrene-divinylbenzene) and a catalyst are directly added after methylal,paraformaldehyde and thionyl chloride are reacted for a certain time, and then chloromethylation is carried out to prepare the chloromethylated beads, and therefore the harm caused by directly usinghighly toxic chloromethyl ether in the traditional process is avoided; when the dry chloromethylated beads prepared by the method are used for carrying out Friedel-Crafts reaction secondary crosslinking, no residual chlorine exists in a generated resin product basically, dichloroethane is used as a swelling agent in the cross-linking process, explosive high-toxicity nitrobenzene does not need to be used as a swelling agent, production is safe, and the prepared macroporous adsorption resin is improved in solvent residue, biocompatibility and other properties.

Description

technical field [0001] The invention belongs to the technical field of blood purification, and in particular relates to a broad-spectrum hemoperfusion macroporous adsorption resin and a preparation method thereof, which are suitable for treating diseases such as uremia, drug poisoning, lupus erythematosus, and excessive bilirubin. Background technique [0002] In contemporary society, with the increasing trend of population aging, the number of patients with "three highs" is increasing, and the number of patients with chronic kidney disease and liver disease caused by this is also increasing. Epidemiological studies have found that the number of patients with renal failure, severe liver disease, and drug poisoning is continuously increasing, which has exceeded early estimates. At present, hemodialysis is the main method for such diseases. However, although dialysis has a history of more than 200 years and has become the main method in the field of blood purification, side ef...
