Title:
APPARATUS FOR MONITORING MICROBES IN AIR AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/118259
Kind Code:
A1
Abstract:
This apparatus for monitoring microbes in air is provided with: a housing provided with a fan for air inflow, the interior of the housing being partitioned by partition boards into spaces for performing a plurality of steps; a perforated plate provided with a plurality of nozzles to make the air from the spaces in the housing flow in a predetermined direction, the perforated plate being provided to a part of the housing; a collection plate provided with a plurality of collection surfaces opposite the plurality of nozzles of the perforated plate; a collection plate control unit for moving the collection plate relative to the perforated plate; and an optical detection unit for detecting the fluorescence emitted from microbes on the collection surfaces of the collection plate. Air containing microbes flows into some of the plurality of spaces inside the housing; a pillar to which a substance that specifically binds with microbes has been bonded is provided on the collection surfaces of the collection plate; the collection plate control unit causes air flow from the plurality of spaces inside the housing to sequentially impact the plurality of collection surfaces of the collection plate via the plurality of nozzles in the perforated plate; and the optical detection unit sequentially detects the fluorescence of the collection surfaces that have been impacted by the flow of air containing microbes among the air flow from the plurality of spaces in the housing.
