母乳喂养过程中的吸奶不仅是由婴儿吮吸时口腔内的真空压力引起的，而且是婴儿下颌的周期性运动，这是本研究的重点。流体-结构相互作用模拟提供了一个更好地了解在人类乳房导管系统的乳房与婴儿的口腔和颌骨相互作用的奶流行为。从闩锁的实例进行模拟，并持续两个周期的周期性舌头运动。根据临床数据测量负压曲线，并应用于模拟。使用超声图像获得乳头尺寸，并将其用作模拟中的边界条件。分别研究了真空压力和外周压力对乳管系统内乳汁流动行为的影响。据观察，管道系统的变形对乳汁流动行为和挤出的乳汁量具有关键影响。
Extracting milk during breastfeeding is not only caused by intra-oral vacuum pressure by the infant suckling but also is the periodic motion of the infant’s jaw, which is the focus of this study. A Fluid-structure interaction simulation provides a better understanding of the milk flow behavior in the human breast ductal system as the breast interacts with the infant’s oral cavity and jaws. Simulations were performed from the instance of latching and continued for two cycles of periodic tongue motion. The negative vacuum pressure profile was measured from the clinical data and applied in the simulation. The nipple dimensions were obtained using ultrasound images and used as boundary conditions in the simulation. The effect of vacuum pressure and the peripheral pressure on the milk flow behavior in breast ductal system were studied individually. It was observed that the deformation of the ductal system has a critical impact on milk flow behavior and the amount of expressed milk.
