[Correction of the composition of the dialyzing solution during its electrochemical regeneration].

The results of a study of parameters of an experimental dialyzate regeneration unit (a key functional unit of a hemodialysis apparatus with the regeneration of dialyzing solution) are discussed in the article.

[Unit of electrochemical oxidation of hemodialysis products--development and research].

Some aspects related with research and development of a key functional unit of the hemodilysis apparatus with the electrochemical regeneration of dialyzate, i.e. the electrochemical oxidation unit which enables a regulated electrochemical oxidation of the main organic hemodilysis products in the waste dialyzate, are described.

[State of the art and outlook for promoting Russian-made hemodialysis equipment with regeneration of dialyzing solution].

Radical improvements in the physiological features and self-sufficiency of hemodialysis equipment, an essential reduction of the volume of dialyzate contacting with patient's body and elimination of dependence of the equipment operation on the availability of a water-supply network can be ensured by applying a regime of circulation of a relatively small volume (3-5 l) of dialyzate through the regenerating device. The regeneration unit must eliminate the organic products of dialysis from the dialyzate and stabilize the ionic composition of the purified dialyzate according to the preset parameters. Modern methods and technical means for regenerating the used dialyzate are discussed; a regeneration unit, which ensures an electrochemical oxidation (in the used dialyzate) of nitrogen-containing organic metabolites with a subsequent sorption-type additional purification of electrochemically-processed dialyzate, is offered.

[Principles for constructing and electrochemical regenerator for dialysis solutions for the "artificial kidney" apparatus].

Controlled removal of the present quantities of renal metabolites from the waste dialysate can be effected by electrochemical regeneration of the worked-out dialysate, which is based on the use of a dialyzing solution electrolyzer (DSE). A theoretical rationale for DSE functioning modes has been provided. A reaction model of urea oxidation on bimetallic titanium-platinum electrodes has been drawn up.
