Abstract
A lung model device for inhalation toxicity testing is provided. The device has a plurality of mesh tissue panels having lung cells attached thereto arranged inside a case so as to have a similar structure to a human lung, and air and nanoparticles are supplied into the case through a separate respiratory operating unit, thereby enabling inhalation toxicity testing on nanoparticles to be simply and conveniently performed in an indirect way by determining changes in the state of the lung cells without using real laboratory animals. The mesh tissue panels having a smaller lattice spacing size are sequentially positioned according to the nanoparticle inflow direction, thereby providing a structure similar to the structure of a real lung.
