An antigen supply deviceaccording to the present invention is mainly configured by a cylindrical memberextending in the vertical direction. An air suction portfor sucking the air in the antigen exposure chamber is provided at a lower end of the cylindrical member. An axial fanthat generates a flow of the air flowing upward in an axial direction of the cylindrical member is attached above the air suction port of the cylindrical member. Moreover, a supply portthrough which high-concentration antigens are jetted from a dust feeder on the outside of the antigen exposure chamber is provided above the axial fan of the cylindrical member. The antigen supply deviceis disposed near the outdoor air diffuser of the antigen exposure chamber, and configured to blow out high-concentration antigens, which are supplied from the dust feeder on the outside of the antigen exposure chamber, to the outdoor air diffuserfrom an upper end of the cylindrical member after mixing the antigens with the air in the antigen exposure chamber sucked from the air suction port and diluting the antigens, and moreover mix the antigens with the outdoor air from the outdoor air diffuser to fill the antigen exposure chamber A with the mixture of the antigens and the outdoor air.

Antigen supply device

An object of the present invention is to solve the problems in conventional art antigen exposure chambers, and specifically, to provide an antigen exposure chamber system capable of simultaneously exposing a large number of test objects in a chamber to a uniform antigen (pollen, mite or house dust, etc.) in all seasons. In order to achieve the above object, in an antigen exposure chamber system according to the present invention, an outdoor air is supplied via an outdoor air diffuserprovided in a ceiling surface of an exposure chamberinto the exposure chamber from the ceiling surface of the exposure chamber in a horizontal direction, a fan unit, including a supply port and a suction port, is provided in each of the four corners of the exposure chamber to provide a circulating flow of air flowing with circulation in the horizontal direction in the exposure chamber, an air exhaust portis provided at a floor surface of the exposure chamber to exhaust an air from the floor surface of the exposure chamber, an antigen is supplied from an antigen supply device to the outdoor air diffuser provided on the ceiling surface so that the antigen is mixed with the outdoor air, and a uniform concentration antigen exposure is enabled by the circulating flow of air.

Antigen exposure chamber system

An antigen exposure chamber for quickly performing cleaning and drying with high quality is provided. The antigen exposure chamber of the present invention includes: a cleaning water supply device for supplying cleaning water for cleaning the antigen exposure chamber; cleaning nozzles for jetting the cleaning water supplied from the cleaning water supply device into the antigen exposure chamber and ducts of fan units to clean the antigen exposure chamber and the ducts; a floor surface of the antigen exposure chamber; and an exhaust device provided below the floor surface to exhaust air from the floor surface of the antigen exposure chamber and collect and drain the cleaning water during cleaning.
