摘要:
A bed monitoring system for monitoring a subject on a bed includes: a plurality of load detectors which are to be placed in the bed or under legs of the bed and which are configured to detect a load of the subject; a center of gravity position calculating unit configured to obtain a temporal variation of a center of gravity position of the subject based on the detected load of the subject; a body motion information determining unit configured to obtain a body motion information based on the obtained temporal variation of the center of gravity position of the subject, the body motion information being an information on a movement of a whole or a part of the whole body of the subject different from a movement caused by a respiration of the subject; a respiratory rate calculating unit configured to calculate a respiratory rate of the subject based on the obtained temporal variation of the center of gravity position of the subject and the body motion information obtained by the body motion information determining unit; and a subject information detecting unit configured to detect at least one of an image information of the subject, an audio information of the subject and a temperature information of the subject.
