DEGLUTITION DETERMINATION DEVICE, DEGLUTITION DETERMINATION PROGRAM AND DEGLUTITION DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To determine presence/no presence of deglutition easily.SOLUTION: A deglutition determination device 1 comprises: a microphone 16 capable of outputting a microphone signal corresponding to a sound accompanied with deglutition; an impedance acquisition part 351A for acquiring an impedance of a muscle of a neck; a sound signal acquisition part 351B for acquiring a sound signal Venv; and a determination part 352 for determining presence/no presence of deglutition on the basis of the sound signal Venv and the impedance BI. An AC current from a current supply part 23 is supplied to a pair of electrodes 12a, 12b, and a voltage measurement part 24 measures a voltage between the pair of electrodes 11a, 11b. The impedance calculation part 351 calculates an impedance from a relationship between the measured voltage and the current.SELECTED DRAWING: Figure 3
