METHOD AND DEVICE FOR BIOHEMOFILTRATION Russian patent published in 2007 - IPC A61M1/34 

FIELD: efferent medicine; extra corporal hemocorrection.

SUBSTANCE: method and device can be used for hemofiltration. Hemofiltration is carried out by means of patient and donor two hemofiltration circuits connected in series. Any circuit has blood pump, membrane mass exchanger, air trap, combined pressure-and-vacuum gage for checking venous and arterial pressure, measuring container with scales, reversible pump, electromagnet valves and devices indication on tear in membranes of mass exchangers. Measuring containers with scales in patient and donor hemofiltration circuits are mounted for feed patient and donor hemofiltrate in them correspondingly and for return of patient's hemofiltrate for discharge and donor hemofiltrate - to patient's air trap. Patient's hemofiltrate is replaced by full-value donor's hemofiltrate. Measuring container with scales in circuit of return of replacing solution is mounted for feed of replacing solution from container filled with replacing solution and for return of replacing solution into donor's air trap.

EFFECT: improved efficiency of hemofiltration; improved speed of elimination of toxic matters from patient's organism.
