METHOD OF BODY FLUID (BLOOD) CLEANING FROM VIRUS INFECTION BY SORPTION ON MAGNETOCONTROLLABLE NANOPARTICLES AND METHOD OF IMPLEMENTATION Russian patent published in 2009 - IPC A61M1/36 B82B1/00 B82B3/00 

FIELD: medicine.

SUBSTANCE: to treat patient suffering from hepatitis B or C, body fluid is sorbed by means of flowing through device comprising suspension preparation assembly equipped with ultrasonic dispergator wherethrough nanoparticle suspension shall flow as nanofraction of cobalt ferrospinel CoFe₂O₄ in spiritus and shall be mixed with body fluid infected by viruses of hepatitis B or C. The device also comprises magnetic filter with entry zone wherein a uniform magnetic field is established rough filtration zone where gradient magnetic field is established from axially magnetised bushing, fine filtration zone wherein alternating high-gradient magnetic field is established. Body fluid, which is free from nanoparticles with sorbed viruses is delivered into vessel for clean body fluid accumulation.

EFFECT: inventions enable to improve sorbtion efficiency relative to antigens and viruses over a wide range of concentrations and concentration weakening in sorbing solution below the limit of poor and positive reaction.
