Abstract

The invention relates to the technical field of air microorganism monitoring, and discloses a bioaerosol early warning device based on an ATP bioluminescence technology. The device comprises a reagent conveying module used for containing a reaction reagent and conveying the reaction reagent to a fluorescence reaction module; a sampling module used for collecting and conveying microorganisms in ambient air to the fluorescence reaction module; the fluorescence reaction module used for mixing the reaction reagent with the microorganisms and generating fluorescence; a monitoring and processing module used for detecting the fluorescence change, converting the fluorescence change into an electric signal, processing the electric signal to obtain the concentration of microorganisms, and sending an early warning signal when the concentration exceeds a preset value; and a waste liquid collection module used for collecting waste liquid after reaction of the fluorescence reaction module. The change of the concentration of microorganisms in air is obtained based on the ATP bioluminescence technology, an early warning signal is sent out when the concentration exceeds a preset value, the overall structure is simple, the function is reliable, the implementation is easy, and the working efficiency of the whole device can be improved.

Description

technical field [0001] The invention relates to the technical field of air microorganism monitoring, and more specifically relates to a bioaerosol early warning device based on ATP bioluminescent technology. Background technique [0002] At present, the main methods used for bioaerosol monitoring at home and abroad include the traditional collection and cultivation method and single particle ultraviolet light-induced fluorescence detection method. The collection and cultivation method is to collect cultivable microorganisms on a solid or liquid medium first, and then grow into colonies to count after cultivation, which can simultaneously measure the concentration and particle size distribution of airborne microorganisms. [0003] The single particle ultraviolet light-induced fluorescence detection method mainly uses the characteristic of biological intrinsic fluorescence to detect bioaerosols. Intrinsic fluorescence refers to the unique fluorescence emitted by organic molec...
