Abstract

METHOD FOR CLEANING DIALYZING BATTERY OF SOLUTION IN THE APPARATUS ARTIFICIAL KIDNEY, passing the circulating solution through a sorption filter with activated carbon, in order to reduce the output of dialysate from inorganic salts and synthetic elements and improve the degree of purification of the dialyses from the dialyses and to decrease the level of dialysis from them. before use, creatinine / activated carbon is treated with metals of a platinum 1 group in the amount of 0.01-0.1 wt.% and is regenerated for repeated use by oxidation on air for 1.52 h at 105-1. 8b C.

Description

CD The invention relates to medicine, in particular, to toxicology, and may be used to purify a dialysis solution in artificial kidney machines from various toxic substances, such as urea, creatinine, and the like. The known method of purification of the digesting solution in the apparatus is -. a coarse kidney, according to which 50 liters of circulating dialysing solution are used and 7.5 kg of coal are used to regenerate dialysate 13. There is also a known method of cleaning the day of lyse solution in artificial kidney apparatus by passing a circulating solution through an activated carbon sorption filter. many times 2 3i. However, using the known method, it is possible to significantly remove from the patient's body the necessary trace elements, such as Co, Ti, Cr, Zi, Sn, etc., which pass through the semipermeable membrane of the dialyzer from the patient's blood to the dialyzing solution, which leads to patients with various diseases, such as anemia, salt metabolism, etc. The purpose of the invention is to reduce the excretion of inorganic salts and trace elements, improving the depth of cleaning of dialysate from urea and creatinine. This goal is achieved, according to the method of wiping the dialysate solution in an artificial soil apparatus, by passing the circulating solution through a sorption filter with activated carbon, and activated carbon is treated with O in the amount of platinum group metals before use (31-0.1 wt.% And regenerate it for repeated use by air oxidation and for 1.5-2 hours at 105-180 s. Using the carbon treated in this way reduces the amount of recirculating dialysis solution to 10 liters and increase the amount of sorbent required for its regeneration to 1 kg. Moreover, due to the promotion of coal with platinum, its sorption capacity for urea and creatinine is increased; C compared to conventional (-800f) 00 ° Cjl. Reducing the temperature, the method “preserves the structure of the sorbent, which, in turn, allows the IOI to use it shorterly. Coals of the SKT-b, SKT-7, PAH-SV grades are promoted. . . Platinum activated carbon is promoted as follows. Dried charcoal is impregnated with a solution of platinum hydrochloric acid and then treated with formaldehyde in an alkaline medium to reduce platinum. The coal is then washed with distilled water and put into active state by heating it in an oven at 105-180 ° C for 1.5-2 hours. On promoted coals, sorption is carried out from the dialyzing solution and after the sorption process is completed, the coal is regenerated by heating in a drying oven at 105-18 ° C for 1.5-2 hours in the presence of air. Sorption is carried out by short circuit 2 l of dialysis solution with the addition of 300 ml of urine of a healthy person. The solution is perfused with a roller pump at a rate of 0.5 l / min through a column with 140 g of dry absorbent. The initial level of urea is 250 mg%, creatinine 23 mg%. The method is carried out as follows. . Two columns with promoted carbon (with a capacity of 0.5 l each) are connected in parallel to the dialysate circuit. of which one works in sorption mode. friend in regeneration. Every hour and a half, the speakers are in places, and dialysis is continuous. The table shows the results of the adsorption capacity of coals odified with 0.01% platinum, depending on the number of regenerations. .t

The table shows that platinized coal can be regenerated more than 10 times and its adsorption capacity practically does not fall.

The proposed purification method, a dialysis solution using promoted coals, has several significant advantages over the known ones. Dialing36

5 with the use of promotion coals allows to increase the depth of cleaning of the dialysis solution from urea and creatinine. The promotion of coal by the amount of platinum leads to repeated use of the same coal, which in turn reduces the removal of inorganic salts and microelements from the patient's body.
