Patent ID: 7959585

Claim:
A device for a time-based analysis of the agitation of a bedridden patient comprising: means ( 4 ) for acquiring data related to the patient's shouts; and means ( 3 ) for acquiring data related to the patient's movements, the acquisition means being connected to storage means ( 9 ) suitable for storing the acquired data accompanied by time-stamping ( 8 ) of said acquired data, connected to analysis and presentation means ( 10 , 11 ) suitable for providing care staff with a representation of frequency and duration of the patient's shouts and movements which are representative of the patient's agitation over a determined time span, wherein the means ( 4 ) for acquiring data related to the shouts comprise a band-pass filter ( 6 ) suitable for isolating shouts from speech and ambient noise, the band-pass filter comprising pass-band selection means between two predetermined bandwidths, said two predetermined bandwidths having a bandwidth of approximately 1500 Hz centered on 2500 Hz for the first and a bandwidth of approximately 900 Hz centered on 1500 Hz for the second, and the means for acquiring data related to the movements comprise a sensor of the vibrations of a patient's bed and an intensity filter adapted so that only the vibrations having an intensity above a predetermined threshold are stored in the storage means.
