ULTRASONIC URINE VOLUME MEASURING INSTRUMENT, AND METHOD OF POSITIONING ULTRASOUND PROBE IN ULTRASONIC URINE VOLUME MEASURING INSTRUMENT

摘要

A mode selector is provided, capable of selecting one of a measurement mode of measuring urine volume while an ultrasound probe is placed at a certain measurement position on the stomach of a measurement subject, and a positioning mode is provided, of measuring urine volume while moving the ultrasound probe to a plurality of tentative measurement positions on the stomach to determine the measurement position suitable for placing the ultrasound probe in the measurement mode. An index value memory is included that stores a maximum value among urine volumes at the plurality of tentative measurement positions, calculated by the arithmetic unit, while the positioning mode is being selected, and/or an allowance value determined on the basis of the maximum value. The maximum value and/or the allowance value is displayed, on a graph on a display unit, as a positioning index value for positioning the ultrasound probe.

主权项

1. An ultrasonic urine volume measuring instrument comprising:
an ultrasound probe that is placed on stomach of a measurement subject, and that includes an ultrasound device that transmits ultrasound toward bladder of the measurement subject at a certain measurement cycle and receives a wave reflected from a wall of the bladder; an ultrasound controller that controls transmission and reception of ultrasound and its reflected wave, the transmission and reception being performed by the ultrasound device; an arithmetic unit that calculates, on the basis of the reflected wave, urine volume in the bladder said every measurement cycle; and a display unit that chronologically displays, as a graph, the urine volume calculated by the arithmetic unit, the ultrasonic urine volume measuring instrument further comprising: a mode selector capable of selecting one of a measurement mode of measuring urine volume while the ultrasound probe is placed at a certain measurement position on the stomach of the measurement subject, and a positioning mode of measuring urine volume while moving the ultrasound probe to a plurality of tentative measurement positions on the stomach in order to determine the measurement position suitable for placing the ultrasound probe; and an index value memory that stores a maximum value among urine volumes at the plurality of tentative measurement positions, calculated by the arithmetic unit, while the positioning mode is being selected, and/or an allowance value determined on the basis of the maximum value, wherein the maximum value and/or the allowance value is displayed as a positioning index value for positioning the ultrasound probe, on the graph on the display unit.
