Swallowing Simulation Apparatus and Method

摘要

To provide a swallowing simulation apparatus that facilitates approximate reproduction of an actual phenomenon of swallowing. The swallowing simulation apparatus comprises: an oral cavity modeling unit 10 configured to form an oral cavity model 11 formed of oral cavity organs; an organ property setting unit 20 configured to set an organ property of each of the oral cavity organs in the oral cavity model 11; an organ movement setting unit 30 configured to set a movement of each of the oral cavity organs in the oral cavity model 11; a food product physical property setting unit 40 configured to set a food product as an analysis target; and a physical property of the food product formed by modeling the food product; an input unit 81 configured to input a pseudo food product to the oral cavity; a movement analysis unit 50 configured to analyze a movement of each of the oral cavity organs and a behavior of the pseudo food product 41 while being swallowed in the oral cavity model 11 using a particle method; and a display unit 82 configured to display an analysis result of the movement of each of the oral cavity organs and the behavior of the pseudo food product 41 on a moving screen while being swallowed, the analysis result being analyzed by the movement analysis unit 50.
