Chapter One Overview
1.1 Introduction
BVT01 bladder olume tester is composed of main unit, probe, etc., which is used to non-in asi ely
measure bladder olume with ultrasound principle. It is used to assess urinary retention and urinary
incontinence, and gi en the timing of implement an objecti e clinical catheterization to reduce the
catheterizing frequency and reduce the risk of urinary tract infections. But also by measuring the amount
of residual urine olume after oiding, e aluate the therapeutic effect of certain drugs and treatment for
urinary system diseases.
BVT01 bladder olume tester uses 2.5MHz ultrasound to mechanical sector scanning, identify the
reflected wa e of the front and rear wall of the bladder to obtain the cross-sectional area of the bladder;
again through 15°inter als to automatically transform the scanning plane, based on the areas of 12
reference plane to calculate the bladder olume with ellipsoid integration.
To impro e the accuracy of the operation and measurement, the screen displays the B-mode image of
section bladder and the projection of bladder; it is con enient for doctors to check the location and
determine the measurement results.
The expected ser ice life of BVT01 bladder olume tester is 10 years. The applied part is the part
between metal ring of probe handle below 5mm and the forefront of the sound head (see Figure 12-1
“Probe regular disinfection”).
BVT01 measurement accuracy must meet the following indicators: Urine olume display resolution
is 1ml. When urine olume is within 20ml～99ml, the measurement accuracy error is less than or equal to
±15ml; urine olume is within 100ml～999ml, the measurement accuracy error is less than or equal to
15%.
In a typical commercial or hospital en ironment, 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 alue and not alter the diagnosis.
2. Electromagnetic disturbance does not make the instrument generate the display of incorrect
numerical alues associated with the diagnosis to be performed.
3. Electromagnetic disturbance does not make the instrument generate the production of unintended
or excessi e ultrasound output.
4. Electromagnetic disturbance does not make the instrument generate the production of unintended
or excessi e transducer assembly surface.
1.2 Intended Use
BVT01 bladder olume tester is used in medical institutions for clinical measuring urine olume, to
pro ide the basis for the implementation of clinical catheterization and make e aluations for the residual
olume after patient oiding.
Contraindications: The equipment is not suitable for pregnant women and infants bladder scan, nor be
scanned on the wounded skin.
Warning:
This equipment can not 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 can not be used to treat.
