<p>A biophysiological detector for collecting biophysiological information on a subject by measuring the load on a bed where the subject exists. The load on a bed (1) where the subject exists is measured, the frequency distribution and the magnitude of variation (amplitude) are determined from a waveform indicative of the variation of the measured load and then the biophysiological information on the subject is acquired from these data. More specifically, a frequency appearing noticeably in a first frequency region is regarded as the respiration rate and a frequency appearing noticeably in a second frequency region higher than the first frequency region is regarded as the pulse rate. The subject is judged to be snoring if the variation in a thirst frequency region higher than the second frequency region increases. The subject judged to cough if the variation increases suddenly. Furthermore, the subject is judged to turn from side to side if the variation of the load exceeds a specified level.</p> |
