ARTIFICIAL KIDNEY APPARATUS Russian patent published in 2002 - IPC

FIELD: medical equipment, in particular, hemodialysis and isolated ultrafiltration apparatuses, applicable in nephrology, surgery, resuscitation and accident medicine for substitution of the lost function of extraction of metabolites and toxicants from the organism. SUBSTANCE: pulsations of consumption of the dialyzing solution at a dosage of dialyzate are reduced by the substitution device due to the use of a membrane batcher, device for control of the level of dialyzing solution in the accumulator with a drive from the deaeration pump, and introduction of two separators. The use of level control device 31 in the apparatus in the form of a membrane batcher prevents ejection of liquid from accumulator 26, which is dangerous with respect to infection of the atmosphere. EFFECT: enhanced dynamic and metrological characteristics of the apparatus. 5 cl, 9 dwg
