procedures, misuse or misapplication of the device, or ignoring specifications and recommendations could
result in increased risk of harm to users, patients and bystanders, or damage to the device.

•

Device captures and presents data reflecting a patient’s physiological condition that when reviewed by a trained
physician or clinician can be useful in determining a diagnosis; however, the data should not be used as a sole
means for determining a patient’s diagnosis.

•

Users are expected to be licensed clinical professionals knowledgeable about medical procedures and patient
care, and adequately trained in the use of this device. Before attempting to use this device for clinical
applications, the operator must read and understand the contents of the user manual and other accompanying
documents. Inadequate knowledge or training could result in increased risk of harm to users, patients and
bystanders, or damage to the device. Contact Mortara Technical Service for additional training options.

●

To avoid the potential for spread of disease or infection, blood pressure cuffs should be cleaned after each
patient use.

•

This device is intended for use with ambulatory patients. This device is not intended for use with unconscious
or sedated patients.

•

Warning: During device configuration using the HDS (Hypertension Diagnostic Suite) Software if a “Top
Inflation Pressure” above 300mmHg is entered the system will automatically enter the value of 300mmHg.
Further, if a “Top Inflation Pressure” above 285mmHg is entered and sent to an AMBULO 2400 device the
HDS software returned an error message. If the AMBULO 2400 device is then disconnected from the system
running the HDS software, the device displays an error “SE 18” indicating “Data memory area is unexpectedly
erased” and the “Top Inflation Pressure” defaults to 180mmHg automatically.

•

Use only approved blood pressure (BP) cuffs specifically intended for use with the Ambulo 2400.

•

Do not fold, clamp, cut, or alter the pressure hose of the cuff or the monitor.

•

Instruct the patients to check the limb connected to the cuff for adequate perfusion, circulation, and function.
Repeated NIBP measurements can lead to hematomas, limb ischemia, and other limb injuries. Kinked or
blocked hoses can lead to prolonged impairment of blood circulation and lead to injury.

•

Educate the patient to relax, rest, and lie still during inflation and pressure measurements. Patient movement can
lead to artifacts or errors.

USER SAFETY INFORMATION

6

•

The pressure measurement might be influenced by patient position, physical conditions, and other factors.

•

Avoid placing the blood pressure cuff on the arm next to where a patient has had a mastectomy.

•

Avoid applying the cuff to a wounded limb as this can cause further injury. Use with caution in patients with
dermatological disease, subcutaneous laceration, or other integumentary compromise as there may exist a skin
damage hazard during electronic NIBP measurements. Follow prudent evidence-based clinical practice to
determine if an electronic blood pressure is safe for these patients.

•

There may be an increased risk of hematomas in patients with serious coagulation problems.

•

Avoid applying the cuff to a limb with a catheter, arterio-venous shunt or infusion pump applied. The cuff
pressure could produce damage to the tissues surrounding the catheter, shunt or the infusion needle, or
compromise the infusion flow.

•

NIBP measurements may be inaccurate or be adversely affected in the presence of arrhythmias, arterial
sclerosis, poor perfusion, diabetes, age, pregnancy, pre-eclampsia, renal diseases, motion artifacts, shivering, or
trembling patients.

•

NIBP cuffs and hoses supplied with the Ambulo 2400 do NOT contain any Latex. If the patient develops an
allergic reaction or rashes, immediately remove the cuff.

•

Inflation of the NIBP cuff can cause a temporary degradation of monitoring of other parameters derived from
the same limb, including invasive pressure and SpO2 measurements. If applicable, place the SpO2 sensor and
the NIBP cuff on different limbs.

•

The Ambulo 2400 should not be used for measurement of blood pressure in neonate patients.

Caution(s)

•

7. Use caution with excess liquid.

8. Do not use excessive drying techniques such as forced heat.

WARNING: Prevent liquid from penetrating the device and do not attempt to clean/disinfect the

device or cuff by submerging into a liquid, autoclaving, or steam cleaning.

WARNING: Certain maintenance and calibration operations of the Ambulo 2400 system, such as

safety processor calibration and deflation rate calibration, should only be performed by Mortara authorized
service personnel.

Confidence Test

•

Place 2 AA batteries in the device, and verify that it successfully powers on, making note if the software version
displayed on the screen is not current (example “1 49”). If the device display eventually alternates between the
time and “PAUSE”, proceed to the next step. If the device displays “HE##”, “SE##” or something other than
PAUSE/time, refer to the “System Troubleshooting Chart”.

•

If firmware is version 1.49 or older, it is recommended that the main processor receive software upgrade (to the
current version) and calibration. But first, verify that the device passes communication testing below.

MAINTENANCE & CALIBRATION

Maintenance and Calibration Procedure

Preventive maintenance and Calibration of the Ambulo 2400 is recommended to be performed at least once per
year.

In order to configure, calibrate and test the Ambulo 2400 ABPM system, a set of custom-developed utilities –
henceforth referred to as CCT (Command & Control Terminal) - must be installed and used on a computer.
Developed using the Python programming language, these utilities can run under Microsoft Windows using the MS­DOS Command Prompt or in a Linux-based environment.

NOTE: Before proceeding with any CCT commands, you must first install and setup the Hypertension
Diagnostics Suite software, as well as Python and CCT with the following instructions.

1. Install current Mortara Hypertension Diagnostics Suite software. This will install the Ambulo 2400 USB driver,

which is necessary for the device to be recognized by the PC.

2. Download and install Python 2.6.1 (location to be determined). Make note of install folder for next steps. For

example, C:\Python26.

3. Download Pyserial 2.5 (Python Serial Extension) (location to be determined) to Python install folder (from

previous step) and install.

4. Download Pywin32-210 (location to be determined) to Python install folder and install.

5. Download and install CCT application software (file location to be determined) to local directory (for

example, C:\CCT).

Perform a Visual Inspection of the Following Items:

•

Device outer casing, coupler and LCD faceplate. Make note of any heavy wear, damage or signs of drop. If
faceplate is cracked, this is likely an early version of this part (which was prone to cracking) and it is
recommended that the entire top cover be replaced (the revised LCD faceplate is more durable). Some early
Tiba devices also have a plastic air socket, which has since been replaced with a more durable metal design. In
the event that a Tiba branded Ambulo 2400 needs service of the outer case, it is recommended that the complete
case be replaced with Mortara branded plastics.

•

If a customer has included accessories with their Ambulo 2400 system, inspect hoses and cuffs for excessive
wear or leaks. If accessories are noted as being in questionable condition, or if the device is suspected of having
leaks, these accessories will be identified during the “leak test” portion of this procedure. If a puncture is
discovered in the hose, it may be possible to trim the damaged piece and salvage the accessory. Otherwise it is
recommended that the customer replace the accessory.

MAINTENANCE & CALIBRATION

19

Communication Testing

•

Verify that the device can successfully communicate with a PC by connecting it via USB cable, and opening the
Hypertension Diagnostics Suite software.

•

Verify that after 3-5 seconds, the device displays “USB”. If it does not, proceed to the next step. Otherwise
open the Hypertension Diagnostics Suite, click “configure device”, select a Demo patient, and then “One Click
Device Programming”. When the software asks if you would like to continue, click “Yes”. If software freezes
or fails during configuration, force quit program, disconnect device, open the program, connect the device, wait
until it is recognized by the PC, and retry. Once successfully configured, put the device in AUTOMATIC mode
by holding the START button for 3-5 seconds. Ensure that the Ambulo 2400 shows the correct time of day (per
the PC clock) and a countdown to the next scheduled measurement. Proceed to Calibration/Calibration
Verification.

•

If the device continues to alternate between PAUSE and the time, reconnect the USB cable to an
alternate port on the PC. If the device does not display USB, then the port has likely failed and the PCB
should be replaced.

MAINTENANCE & CALIBRATION

20

Main Processor Calibration - (Using CCT commands)

(Note: It is recommended that the device be checked and calibrated once every year, in
accordance with ANSI/AAMI/ISO 80601-2-30:2009 & A1:2013 standards.)

CAUTION: Incorrectly calibrating the device will result in erroneous measurements. Only
attempt to calibrate the device when absolutely certain the process can be completed
successfully.

UUT correct calibration setup requires the following components:

• Ambulo 2400 device

• Manometer/NIBP Simulator

• T-connector air hose

• Sphygmomanometer Manual Hand pump

• USB cable

Once the components are setup correctly (refer to diagram shown), proceed with the calibration process.

1. At the computer’s command prompt will display as below:

2. At the computer’s command prompt at location C:\CCT, set max pressure to 285 mmHg by entering the

Err 41

Pressure timeout to high
pressure limit. Device leaks

Correct air leak by testing accessories
and device using NIBP simulator,
replace leaking accessories or
complete electro-mechanical assembly
if device cannot pass leak test

Err 40 and/or Err 162

Rare, and have often been
reported together. Device
would not inflate

PCB and prop valve had to be
replaced. Or cuff may have leak.

Err 163 and/or Err 23

Err 23 has been reported
alongside Err 163. Associated
with complaints of Slow
deflation, sometimes

Typically solved by upgrading to
firmware with dynamic deflation
adjustment (V1.47 or newer) and
calibrating main processor

Err 166

Overpressure error, meaning
that the pressure has reached
higher levels than the max
set. Device miscalibrated,
typically in the field

Device needs main processor
calibration
Err 164

Associated with complaints of
slow deflation and older
firmware

2. Run the Flash Magic utility, by opening the Flash Magic icon from the TF-0539 desktop. Select the
appropriate COM port and a speed of 38400.
Select LPC2146 for the Device, none for Interface, and 12 MHz for Oscillator.

3. Click “Start”. This will program the main processor.
(The Programming will display “Finished”).

4. After the Programming is finished, Power down the Power Source, and then release the handle of the
Fixture. The board now should be upward position and the Fixture handle should be ½ way up.

If the programming fails, you will know from a resulting error. Most likely this would be due to the
programming leads failing to maintain contact for the duration of programming.

(Note: If the programming fails, the process can be repeated until successful)
