内容記述
Triangle odor bag method adopts a self-suction method as a general method of sniffing. However, there is concern about the decrease in suction concentration from the odor bag because of the dilution with the air existing in the mask or the air entering through gaps between the mask and the face. We conducted CFD analysis in order to easily predict airflow properties. Moreover, the measurement of air suction volume assuming the threshold measurement was also conducted in order to verify of the boundary condition in CFD analysis and to grasp the effect on measured thresholds. Consequently, it was revealed that the decrease of odor concentration suctioned from the odor bag was dependent on both the volume of breath, and widths of clearance between the mask and the face. However, there was a small effect on measured thresholds.
