Mechanical device for balancing fluids during hemofiltration in dialysis treatment

摘要

1. Device for continuous balancing of filtrate and substitution solution in therapeutic methods for the elimation of harmful substances from the human organism, having a mechanical balance (1, 3, 4, 7), the load side of which can be loaded by the total of the masses of the filtrate (11) and of the substitution solution (10), and a restriction and shut-off element (18), mechanically connected to the balance, for controlling the feed of substitution solution, characterized in that, for utilizing gravity as the driving force for the feed flow (12) of substitution solution to the patient and also for the outflow (13) of the filtrate from the patient and from the filter, in particular for balancing in the case of spontaneous arteriovenous blood filtrations, the substitution solution vessel (10) is arranged above the filtrate vessel (11).
