    摘要: An apparatus and methods to quantify the volume of urine in a human bladder with a limited number of acoustic beams is disclosed. In a first version a plurality of narrow ultrasound beams is transmitted in different directions towards the bladder. Returning echoes are converted to digital form and stored in memory. A volume display on the apparatus allows to define the optimal apposition of the transducer assembly. Signal processing software automatically determines the bladder Depth D and Height H and computes the volume of urine. In a second version, a single wide angle ultrasound beam transducer transmits ultrasounds signals at a fundamental frequency to quantify the urine volume. Return signals originating from a depth beyond the usual position of the posterior wall depth of a filled bladder are analyzed for presence of higher harmonic signals, which in turn are related to the presence or absence of urine.

    摘要: An apparatus and methods to quantify the volume of urine in a human bladder with a limited number of acoustic beams is disclosed. In a first version the apparatus is composed of a transducers assembly that transmits a plurality of narrow ultrasound beams in different directions towards the bladder and receives the returning ultrasound signals; a receiver detector for processing the returned signals; an analog-to-digital converter; a memory to store the digitized data and a volume display allowing to define the optimal position of the transducer assembly. The apparatus also includes a signal processing software that automatically determines the bladder Depth D and Height H and computes the volume of urine using an empirical formula corrected by specific, empirically measured, filling dependant correction factors. In a second version a single wide angle ultrasound beam transducer transmitting ultrasound signals at fundamental frequency is used to quantify the urine volume. Return signals originating from a depth beyond the usual position of the posterior wall depth of a filled bladder are analyzed for presence of higher harmonic signals which in turn are related to presence or absence of urine. Both methods or a combination thereof can be used us a simple warning device for presence of residual urine after voiding or indicate the presence of a critical bladder urine filling level.

    摘要: The electronic catheter displacement sensor comprises a displacement sensing roller and an idler roller between which a catheter can be advanced or retracted, circuitry for sensing the rotation of the displacement sensing roller, circuitry for determining the direction in which the displacement sensing roller is rotated, and circuitry coupled to said rotation sensing circuitry and to said direction sensing circuitry for generating an output signal for transmission to a visual display device for displaying the distance the catheter has been advanced or retracted. The rollers can be mounted in a sensor unit separable from the displacement sensor and the sensor unit is preferably disposable.
