Title:
METHOD OF DETECTING COVID-19 BY ANALYSIS OF EXHALED AIR
Document Type and Number:
WIPO Patent Application WO/2023/153958
Kind Code:
A3
Abstract:
The invention relates to the non-invasive detection of COVID-19 by measuring parameters of the gaseous medium exhaled by a person undergoing examination. The present method is carried out using a device (8) containing a gas sensor cell (4) for analyzing exhaled air. The cell comprises an array (1) of gas sensors with different response mechanisms, an air temperature sensor (2), an air humidity sensor (3), a measuring unit (5), a microprocessor (6), and a means for collecting and feeding air into the cell. Exhaled air is fed into the cell. The temperature and humidity of the air are measured. The temperature of the sensors is altered. A voltage pulse is fed to electrodes of the gas sensors. The response parameters of each sensor are measured. The likelihood that the person undergoing examination has coronavirus disease is determined by analyzing the averaged sensor response values according to a classifier produced using sensor response measurements from samples of healthy and COVID-19 infected persons. The result is the rapid detection of COVID-19, which can be used in test systems for day-to-day screening of individuals in crowded places with highly accurate measuring results due to an uncorrelated response from individual sensors in an array, thus providing maximum effectiveness in a minimum of analysis time.
