PHYSICAL CONDITION DETECTING DEVICE, PHYSICAL CONDITION DETECTING METHOD AND BED SYSTEM

摘要

There is provided a body state detecting apparatus (100) for detecting a body state of a subject on a bed. The body state detecting apparatus (100) includes a plurality of load detectors (11, 12, 13, 14) which are placed in the bed or under feet of the bed and which detect a load variation depending on a respiration of the subject; and a body state detecting unit (32, 33) which determines an extending direction of a body axis of the subject and/or a head placement of the subject based on the detected load variation.
