Adsorbing agent used for adsorbing toxins in renal failure patients and preparation method of adsorbing agent

Abstract

The invention relates to an adsorbing agent for adsorbing toxins in renal failure patients and a preparation method of the adsorbing agent. The preparation method comprises the following steps: step 101: an adsorbing agent with particle sizes of 1mm-1.5mm is chosen, and then low-temperature skeleton carbonization treatment is performed; step 102: after the low-temperature skeleton carbonization treatment is finished, the obtained adsorbing agent is subjected to medium-temperature impurity removing treatment in an inert gas atmosphere; step 103: after the medium-temperature impurity removing treatment is finished, the obtained adsorbing agent is subjected to pore preparing treatment under the action of mixed gases; and step 104: after the pore preparing treatment is finished, pore activation treatment is performed, after the pore activation treatment is finished, biological compatibility treatment is performed, and therefore the adsorbing agent used for adsorbing the toxins in the renal failure patients is obtained. The adsorbing agent provided in the invention can effectively adsorb intestinal uremia toxin-like substances, so the toxin content in blood is reduced, and the toxicity effect of the toxins entering the blood is reduced; and patient diseases are effectively relieved, meanwhile, the efficiency of dialysis is remarkably improved, the frequency of the dialysis is reduced, and patient life quality is improved.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an adsorbent for absorbing toxins in patients with renal failure and a preparation method thereof. Background technique [0002] Patients with renal failure will gradually lose their physiological functions as the kidney function, and the continuous failure will cause the continuous accumulation of toxins in the body and cause more serious complications. Most of the toxins in the body come from the decomposition of food by the intestinal flora, and enter the blood to synthesize toxic substances with corresponding toxins (such as indoxyl sulfate, p-cresol sulfate, creatinine, urea nitrogen, etc.). It is easy to combine with protein in the blood, and it is difficult to remove it by ordinary blood purification methods. In recent years, the number of patients who have to undergo dialysis due to decreased renal function has shown a tendency to gradually increase. [0003] Renal failure inclu...

Problems solved by technology

As the number of patients with chronic renal failure increases, the complications caused by it also increase, such as hypertension, anemia, heart failure, pericarditis, cardiomyopathy, hydroelectric disturbance, etc.; the main treatment method is dialysis , kidney transplantation and drug therapy, etc. Among them, dialysis is still the main clinical method for the treatment of chronic renal failure, but dialysis requires long-term maintenance treatment and the frequency of dialysis is high
