Chapter One Overview
1.1 Introduction
BVT01 bladder volume tester is composed of main unit, probe, power adapter, etc., which is used to
non-invasively measure bladder volume with ultrasound principle. It is used to assess urinary retention and
urinary incontinence, and given the timing of implement an objective clinical catheterization to reduce the
catheterizing frequency and reduce the risk of urinary tract infections. But also by measuring the amount
of residual urine volume after voiding, evaluate the therapeutic effect of certain drugs and treatment for
urinary system diseases.
BVT01 bladder volume tester uses 2.5MHz ultrasound to mechanical sector scanning, identify the
reflected wave of the front and rear wall of the bladder to obtain the cross-sectional area of the bladder;
again through 15°intervals to automatically transform the scanning plane, based on the areas of 12
reference plane to calculate the bladder volume with ellipsoid integration.
To improve the accuracy of the operation and measurement, the screen displays the B-mode image of
section bladder and the projection of bladder; it is convenient for doctors to check the location and
determine the measurement results.
The expected service life of BVT01 bladder volume tester is 6 years.
BVT01 measurement accuracy must meet the following indicators: Urine volume display resolution
is 1mL. When urine volume is within 20mL～99mL, the measurement error is ±15mL; urine volume is
within 100mL～999mL, the measurement error is ±15%.
In a typical commercial or hospital environment, the use of instrument depends on the following
essential performance:
1. Electromagnetic disturbance does not make the instrument generate artifacts or distortion in an
image or error of a displayed numerical value and not alter the diagnosis.
2. Electromagnetic disturbance does not make the instrument generate the display of incorrect
numerical values associated with the diagnosis to be performed.
3. Electromagnetic disturbance does not make the instrument generate the production of unintended
or excessive ultrasound output.
4. Electromagnetic disturbance does not make the instrument generate the production of unintended
or excessive transducer assembly surface temperature.
1.2 Intended Use
BVT01 bladder volume tester projects ultrasound energy through the lower abdomen of the patient to
obtain images of the bladder which is used to calculate bladder volume noninvasively. The BVT01 bladder
volume tester is intended to be used onlyby qualified medical professionals.
Contraindications: The equipment is not suitable for fetal use or pregnant patients, patients with
ascites, patients with open or damaged skin, wounds in the suprapubic region.
Warning:This equipment cannot be used at home.
Attention: For patients with hypertrophy of the prostate, space occupying disease or
scars, there is a risk of producing a result exceeding the given accuracy range.
Warning:This equipment cannot be used to treat.
