Title:
DEGLUTITION SIMULATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2013/146436
Kind Code:
A1
Abstract:
Provided is a deglutition simulation device facilitating approximate reproduction of actual phenomena pertaining to deglutition, and making it possible to quantify the physical properties of an orally ingested article and the physical quantities involved in the behavior. This deglutition simulation device (100A) is provided with: a head and neck modeling unit (10) for forming a dynamic three-dimensional head and neck model (10a) comprising the head and neck organs; an organ movement setting unit (30) for setting the movements of each of the head and neck organs in the head and neck model (10a); an orally ingested article physical property setting unit (40) for setting an orally ingested article, serving as an analysis subject, and physical properties thereof; an input unit (81) for inputting into the oral cavity a simulated orally ingested article (20) obtained by modeling the orally ingested article; a movement analysis unit (50) for using a particle process to analyze, in three-dimensional space, the movement of each of the head and neck organs in the head and neck model (10a) and the behavior during deglutition of the simulated orally ingested article (20); and a display unit (82) for displaying on a video screen the results of analyzing the movement of each of the head and neck organs and the behavior during deglutition of the simulated orally ingested article (20) as analyzed by the movement analysis unit (50).
