Document Type and Number:
WIPO Patent Application WO/2011/118256
Kind Code:
A1
Abstract:
In order to provide a collection unit using a collection carrier which is capable of efficiently collecting airborne bacteria even if the collection unit is reduced in size, a collection unit (80) is equipped with: a collection carrier cartridge (82) comprising a carrier filling dish (82b), the center of which has a through hole (82b3) into which a feeder nozzle for warm water or ATP reagent is inserted, and into which is filled a collection carrier (90) that collects airborne bacteria on the outer periphery of the through hole (82b3), and an upper lid (82a) on which a protrusion that passes through the through hole (82b3) is formed and on which the carrier filling dish (82b) is placed; an impacter nozzle head (86) on which a plurality of nozzle holes (87) are formed which face the surface of the collection carrier (90), and which covers the surface of the collection carrier (90); and a fan (84) that introduces air to the surface of the collection carrier from the nozzle holes (87). The flow rate of air that passes through the nozzle holes (87) falls within the range of 40m/s to 50m/s.
