METHOD OF NON-INVASIVE EXPRESS DIAGNOSTICS OF INFLAMMATORY PROCESS IN RESPIRATORY ORGANS OF CALFS Russian patent published in 2015 - IPC A61D99/00 B82B1/00 

FIELD: veterinary science.

SUBSTANCE: condensate of exhaled air is collected and equilibrium gas phase above it is analysed using the detecting device of "electronic nose" type based on massif of three piezosensor with the base frequency of oscillations 10-15 MHz the electrodes of which are coated with films of acetone solutions of bromocresol blue (BCB), triton X-100 (TX-100) and chloroformic suspension of multilayered carbon nanotubes (MCNT) with the coating mass after solvent removal 4-10 mcg. Registration in the program of "electronic nose" of maximum signals of the massif of pyezosensors during 60 s and calculation of the inflammation parameter (IP) by the formula: $$IP=\frac{\sqrt{\Delta F_{TX-100}^2+\Delta F_{BCB}^2-\Delta F_{TX-100}\cdot \Delta F_{BCB}\cdot \sqrt{2}}}{\sqrt{\Delta F_{BCB}^2+\Delta F_{MCNT}^2-\Delta F_{BCB}\cdot \Delta F_{MCNT}\cdot \sqrt{2}}},$$ where ΔF_BCB - maximum change of frequency of oscillation of the pyezosensor with BCB film, ΔF_TX-100 - maximum change of frequency of oscillation of the pyezosensor with TX-100 film, ΔF_MCNT - maximum change of frequency of oscillation of the pyezosensor with MCNT film, diagnosing in respiratory organs of calves of inflammatory process at PV value above 1.2±0.1.

EFFECT: invention allows to diagnose quickly inflammatory processes in respiratory organs of calves.
