Abstract: Urine amount estimation device 100 is provided with ultrasonic sensor 1 which transmits ultrasonic waves into the body and which detects waves produced by reflection of ultrasonic waves; and estimating unit 52 which estimates the amount of urine in the bladder based on whether reflected wave W3 from the bladder detected by ultrasonic sensor 1 is present and/or based on the magnitude of reflected wave W3 from the bladder detected by ultrasonic sensor 1.
Abstract: A stool amount estimating apparatus includes: an ultrasonic sensor that detects a position of a wall of the urinary bladder; and an estimator that estimates a stool amount accumulated in a rectum based on an output of the ultrasonic sensor.
Abstract: The bowel movement prediction device (100) includes an ultrasonic sensor (1) that detects a width of a rectum and a determiner (52) that determines a bowel movement timing based on an output of the ultrasonic sensor (1).
