Operations & Maintenance Manual: Important Information
Ensure proper distance from patient. When transmitting data to or from your computer,
make sure the BladderScan BVI 9400, accessories, and computer are outside the patient vicinity
(more than 2 m [6 ft] from the patient).
WARNING
Risk of explosion, fire, or serious injury.
The BladderScan BVI 9400 is powered by a
lithium‑ion battery. Failure to note the following when handling the battery may result in serious
injury:
• Never short‑circuit the battery by either accidentally or intentionally bringing the battery
terminals into contact with any other conductive object. This could cause serious injury or fire
and could also damage the battery and the BladderScan device.
• Never expose the battery to abnormal shock, vibration, or pressure. The battery’s internal
protective covering could fail, causing it to overheat or ignite, resulting in caustic liquid
leakage, explosion, or fire.
• Do not disassemble, heat above 60°C (140°F), or incinerate the battery. Keep battery out
of reach of children and in original package until ready to use. Dispose of used batteries
promptly according to local recycling or waste regulations.
• If the battery is leaking or its case is cracked, put on protective gloves to handle it, and
discard it immediately. Always dispose of used batteries in compliance with all applicable
laws and regulations. Put insulating tape, such as cellophane tape, on the electrodes during
transportation in order to avoid a possible short circuit, fire, or electrical shock.
WARNING
Risk of patient injury and inaccurate measurements/results.
When using the instrument,
be aware of the following conditions that can affect ultrasound transmission and decrease the
accuracy of exam results.
• Use care when scanning patients who have had suprapubic or pelvic surgery. Scar tissue,
surgical incisions, sutures, and staples can affect ultrasound transmission and accuracy.
• A catheter in the patient’s bladder may affect the accuracy of the bladder volume
measurement in two ways: 1) by introducing air into the bladder that may block the
ultrasound signal, and 2) by having the catheter‑retaining balloon interfere with the volume
measurement. However, the volume measurement may still be clinically useful if it is large
(detecting a blocked catheter, for example).
• Obesity may affect bladder volume measurements. Lift as much abdominal adipose tissue
out of the way of the instrument as possible. Apply more pressure to the probe to reduce the
amount of adipose tissue through which the ultrasound must pass.
Accuracy is compromised if the user does not obtain an optimal, repeatable image.
