The utility model belongs to the field of in-vitro
inhalation and
exposure, and particularly relates to a bionic
breathing type
exposure system for inhales. The
system comprises a
breathing power device, a mouth
branch and a
nose branch, the mouth
branch and the
nose branch are connected with the
breathing power device, the downstream of the mouth branch and the downstream of the
nose branch converge to form a
throat structure and then are connected with a trachea branch, and the trachea branch comprises a bronchial tree with a plurality of branches. The mouth branch and / or the nose branch are / is connected with a diverter valve used for adjusting the diverter flow of the mouth branch and the nose branch; at least one of the branches is connected with a
lung unit
exposure device; the
lung unit exposure device comprises a microporous membrane for
cell growth, a
gas chamber and a liquid chamber, wherein the
gas chamber and the liquid chamber are located on the two sides of the microporous membrane respectively. According to the utility model, the grading and
shunting environment of a bronchial tree where cells are located can be accurately simulated, the respiratory physiological microenvironment where the cells are located can be reduced, and the exposure
dose of the cells can be accurately evaluated, so that a more accurate
cell exposure experiment result can be obtained.
