APPARATUS FOR NON-INVASIVELY MEASURING THE VOLUME OF URINE IN A HUMAN BLADDER

摘要

An apparatus for measuring the volume of urine in a human bladder, including a means for transmitting a plurality of ultrasound signals (10, 24) through the bladder and for receiving the returned ultrasound signals (10, 24). The apparatus further includes means for processing the received analog signals (26), means for converting the analog signal into a series of digital data elements and means for processing the data elements to detect selected portions of the border of the bladder, determine the interwall separation and compute the volume of urine in the bladder (12, 34).
