METHOD OF MONITORING ACETONE LOW IMPURITIES IN THE EXPIRED AIR AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC G01N21/73 G01N33/497 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to medical diagnostics of the presence of acetone in the expired air of a patient. Method of measuring concentration of acetone in the expired air is based on measuring the level of acetone content according by the discharge emission lines at low pressure of the expired air sample of a patient with setting of the concentration of water steams, determined by the parameters of glow discharge. Proposed device consists of discharge tube with the discharge in the pumped through the tube of the expired air of a patient combined with visible wavelength range spectrometer and with a possibility of decoding and interpretation of emission spectra. Using the invention provides the possibility of non-invasive control of glucose content in diabetic's blood by measurement of acetone concentration in the expired air in real time.

EFFECT: invention provides to increase accuracy and measuring sensitivity of acetone impurities concentration in the expired air of a patient, as well as to simplify the design and to expand the range of devices of this purpose.
