ULTRASONIC QUANTIFICATION OF AN INTERNAL PROPERTY OF A MATERIAL

摘要

A device and method for the rapid quantification of the amount of urine in a human bladder. Ultrasonic transducer (1) is positioned in proximity to the bladder (12-13), and excited by pulser/receiver (3) under command of logic (4) to launch an acoustic wave into patient (2). This wave interacts with the bladder walls (12, 13) and is reflected back to the transducer (1), whence it is amplified and processed by pulser/receiver (3). The resulting signal is digitized by analog-to-digital converter (5) under command of logic (4), and stored in memory (6). The software in logic system (4) determines the amount of urine in the bladder as a function of the propagated ultrasonic energy and based on programmed scientific measurements and past history with the specific subject, and actuates an alarm.
