<p>PURPOSE:To detect the state immediately before urination with high accuracy, by judging the state immediately before urination from both of brain wave data and bladder internal pressure data. CONSTITUTION:The detection outputs of both of a brain wave electrode 1 and a bladder internal pressure sensor 2 are amplified by the amplifiers 41, 42 of an urination alarm main unit 4 and the output of the amplifier 41 is divided into respective bands by a frequency filter 43 and the output of said filter 43 is supplied to a brain wave level discrimination circuit 44 to be compared with a set level at every band to be discriminated. The output of the amplifier 42 is supplied to an internal pressure level discrimination circuit 45 to be compared with a set level to be discriminated. The outputs of said discrimination circuits 44, 45 are supplied to a judge circuit 46 and, when bladder internal pressure attains a set level or more or when each band of a brain wave attains each set level or more or less, the judge circuit 46 judges the state immediately before urination to sound a buzzer 3 and a patient is awaken.</p> |
