CAGE TYPE APPARATUS FOR TESTING INHALATION TOXICITY OF AEROSOL PATICLES

摘要

PURPOSE: A cage-type inhalation toxicity testing device is provided to easily implement an inhalation toxicity test and reducing costs required for installation and operational processes. CONSTITUTION: A cage-type inhalation toxicity testing device includes a plurality of cages(400) and an aerosol particle feeder. The cages include exposed chambers(C). The aerosol particle feeder feeds aerosol particles to the exposed chambers. The aerosol particle feeder separately adjusts the concentration of aerosol particles fed to the exposed chambers. The aerosol particle feeder includes a particle generating unit, one feeding chamber, a pressure maintaining unit, and a particle concentration adjusting unit. The particle generating unit generates particles of aerosol state. The feeding chamber stores aerosol particles in a fixed pressure state and is in connection with the cages through a pipe. The pressure maintaining unit maintains the internal pressure of the feeding chamber. The particle concentration adjusting unit is mounted at the pipe connecting the feeding chamber and the cages.
