[Sorption unit for regeneration of dialysis solution in artificial kidney]. / Sorbtsionnyi blok dlia regeneratsii dializiruiushchego rastvora v apparate "iskusstvennaia pochka".

The authors present the results of the tests of an adsorption unit model for a renal dialyzer comprising ligand-metabolic material. The solution is effectively purified of urine, ammonium, creatinine, uric acid, sulphates and phosphates. Hydrodynamic properties of the unit were investigated. The resistance of the unit in operating condition does not exceed 150 mm Hg.

[Preparation of water at kidney centers using separating counterosmosis equipment]. / Vodopodgotovka v pochechnykh tsentrakh s ispo'lzovaniem razdeli- te'lnykh obratnoosmoticheskikh apparatov.

A water treatment AKBA-I unit intended for the renal centers was tried. The unit includes a clarifier, an adsorber, a softener, a reflux osmotic separator and electronic systems for the control of hydrodynamic processes. The trials demonstrated the unit to be highly effective as regards the removal from water of salts of hardness, of iron, potassium, oxidizable substances and active chlorine. The pH value of the filtrate (7.1-7.4) appeared to meet the requirements made during the preparation of a dialyzing solution. The concentration of sodium ions in the filtrate was 0.75 mg.eq/l, which did not influence the concentration of sodium ions in the dailyzing solution during its preparation from dry concentrate. During operation of the unit, the selectivity of the APO membrane in the operating mode was defined. It amounted to 85%.

[Deodorant gaskets for colostomy patients]. / Issledovanie dezodoriruiushchikh prokladok dlia bol'nykh s kolostomoi.

The results of the experiments for the objective evaluation on a model system of the protective effect of deodorant gaskets on colostomy patients are given. It has been determined that the deodorant capacity of the above gaskets is more than two times higher than that of its "washer filter" analog manufactured by the foreign "Coloplast" company.
