GAS SENSOR CELL FOR NON-INVASIVE ANALYSIS OF HUMAN EXHALED AIR Russian patent published in 2022 - IPC G01N33/497 

FIELD: human condition research.

SUBSTANCE: invention relates to the field of research of the human condition by measuring the parameters of the composition of the inhaled air. Gas sensor cell for non-invasive analysis of the air exhaled by a person, including: an array of 1 to N semi-selective gas sensors with a different response mechanism selected in such a way as to give an uncorrelated response to disease markers contained in the exhaled air, an air temperature sensor, a relative air humidity; a measuring unit connected to the array of gas sensors, configured to apply a voltage of arbitrary amplitude to the electrodes of each gas sensor in the array and measure the time dependence of the value of the response parameter of each gas sensor in the array; a microprocessor to which a measuring unit, an air temperature sensor, a relative air humidity sensor are connected, while the microprocessor is configured to calculate the response value of each gas sensor in the array, average the obtained sensory response values, determine the probability of disease by analyzing the average sensory response values according to the classifier, previously stored in the memory of the microprocessor and obtained by measuring the sensory response for various samples of people with a particular disease or comparing average response values to compare the degree of a known disease.

EFFECT: improving the accuracy and reliability of measurement results.
