The authors present a new technique for studying airflow patterns and particle deposition in the nasopharynx. The nasal cavities and the nasopharynx from the head of a human cadaver were filled with siliconrubber and a "positive" model was then produced by moulding with plastic. An apparatus was constructed to provide calibrated flow of propandiol in both directions. Flow characteristics were visualized by introducing small particles in suspension or by injecting methylene blue with a needle. In addition, test aerosol was drawn in through the model to demonstrate dust deposition sites in the nasopharynx. In the future, this method will enable us to examine the nasopharyngeal airflow patterns and deposition sites of inhaled particles.
作者介绍了一种研究鼻咽部气流模式和颗粒沉积的新技术。将人类尸体头部的鼻腔和鼻咽部填充硅橡胶，然后用塑料模制出一个“阳性”模型。构建了一种装置，以提供丙二醇在两个方向上的校准流动。通过引入悬浮的小颗粒或用针注射亚甲蓝来观察流动特性。此外，将测试气雾剂通过模型吸入，以展示鼻咽部的灰尘沉积部位。未来，这种方法将使我们能够研究鼻咽部的气流模式和吸入颗粒的沉积部位。
