Air pathogen real-time monitoring and identifying instrument and identifying method

Abstract

The invention provides an air pathogen real-time monitoring and identifying instrument, which comprises a housing, a first monitoring module, a second monitoring module, a control module and a power supply module. The first monitoring module comprises a sampling head, a first air pump and an aerosol sensor which are connected through a breather pipe; the second monitoring module comprises a liquidstorage bottle, a sampling needle, a second air pump, a sample adding device and an immunoassay analyzer; the sample adding device comprises a liquid suction pump and a sample adding needle; the liquid storage bottle is provided with an air inlet; the liquid storage bottle and the second air pump are connected through the breather pipe; the sampling needle extends into the liquid storage bottle;the sampling needle, the liquid suction pump and the sample adding needle are connected through a liquid pipe; the immunoassay analyzer is provided with a chip moving device, and the chip moving device is provided with a micro-fluidic chip; and the first monitoring module, the second monitoring module and the power supply module are electrically connected with the controller. The invention furtherprovides an identifying method; and automation and effectiveness of pathogen detection are improved, and integration of real-time monitoring and sampling identification is achieved.

Description

technical field [0001] The invention relates to the field of environmental detection, in particular to an airborne pathogen real-time monitoring and identification instrument and identification method. Background technique [0002] With the progress of society, industrial automation and rapid transportation, the air pollution of the public environment is becoming more and more serious due to the increase of floating population. In terms of hygiene, the key considerations are that aerosol pollutants with pathogenic microorganisms are contagious. When the human body is inhaled, they may be infected and cause harm to human health. For example, pathogens of 2019-nCoV, SARS, H1N1 influenza, MERS, H7N9 influenza, H5N1 avian influenza and other diseases are easily transmitted through aerosols. [0003] Efficient and comprehensive sampling is the prerequisite for accurate detection of airborne pathogens. There are three main conventional sampling methods for airborne microorganisms...

Problems solved by technology

[0004] At present, there are microbial samplers on the market, which need to manually transfer the samples and then detect the types of microorganisms. The process takes a long time and is complicated to operate. It is easy to cause losses to the collected microorganisms and affect the detection results. Real-time online monitoring cannot be carried out. Integration of sampling and identification, giving early warning
