Abstract:
An on-bed state monitoring system (100) for monitoring an on-bed state of a subject on a bed (BD) is provided with: four load detectors (11, 12, 13, 14) which are provided at the four corners of the bed and detect a load on the subject; and a sitting-square determination unit (33) which, on the basis of a change in the magnitude relationship of detected values from two load detectors which are included in the four load detectors and are arranged diagonally across the bed, predicts that the subject will reach a sitting-square state.
