Abstract
A present-in-bed state monitoring system (100) configured to monitor a present-in-bed state of a subject on a bed (BD) includes: a plurality of load detectors (11, 12, 13, 14) configured to be provided on the bed or under legs of the bed to detect a load of the subject; a center of gravity position calculating unit (31) configured to calculate a center of gravity position of the subject based on the detected load of the subject; a waveform output unit (32) configured to output a waveform including a respiratory waveform of the subject based on a temporal variation of the calculated center of gravity position; a center of gravity position determining unit (332) configured to determine whether or not the center of gravity position is in an edge area of the bed; a body motion determining unit (331) configured to determine whether or not the subject has a body motion based on the waveform including the respiratory waveform of the subject, the body motion being different from a respiration of the subject; and a notifying unit (5) configured to perform a notification about the present-in-bed state of the subject based on a determination result of the body motion determining unit and a de…
