● important precautions, provide instructions or explanations to make

better use of this product.

WARNING

Page 7

Defibrillator Monitor S Series Service Manual

● This defibrillator is intended for use in clinical patient care and only allows

trained physicians and nurses to use the defibrillator.

● Before use, the user should check that the instrument and its accessories

are working properly and safely.

● The alarm volume and alarm upper and lower limits should be set for

different patients. When monitoring a patient, do not rely solely on the

audible alarm system to monitor the patient. If the alarm volume is set too

small or completely turned off, the alarm may be invalidated and the

patient's safety may be compromised. The most reliable method of patient

monitoring should be to pay close attention to the actual clinical condition

of the patient.

● This device can only be connected to a power outlet with protective

grounding. If the power socket is not connected to a grounding wire, do

not use the socket and use a rechargeable battery device to supply power.

● Do not open the case of the instrument to avoid possible electric shock

hazards. Any repairs and upgrades to the monitor must be performed by a

service person trained and authorized by Comen.

● When handling packaging materials, they should be disposed of in

accordance with local laws and regulations or the hospital's waste disposal

regulations. Packaging materials must be placed out of reach of children.

Page 8

Defibrillator Monitor S Series Service Manual

● Do not use the instrument in a location where flammable materials such as

anesthesia are placed to prevent an explosion or fire.

● Carefully install the power cord and various accessory cables to avoid

patient entanglement or suffocation, cable entanglement, or electrical

interference.

● Do not use a mobile phone near the monitor. The mobile phone generates

an excessive radiation field and interferes with the monitor's function.

● For patients with pacemakers, the heart rate monitor may pulse

pacemakers during cardiac arrest or arrhythmia. Do not rely solely on the

heart rate monitor alarm. Patients with pacemakers should be closely

monitored. Refer to the monitor's instruction manual for the ability of the

device to suppress the pacemaker.

● During defibrillation, the operator should not touch the patient, the table

and the instrument. Check that the function is normal before using these

cables again.

● The interconnecting device with the monitor should form an equipotential

body (the protective ground is effectively connected).

● When the monitor is shared with the electrosurgical device, the user

(doctor or nurse) should ensure the patient's safety.

Page 9

Defibrillator Monitor S Series Service Manual

● The physiological waveforms, physiological parameters and alarm

information displayed by the monitor are for medical reference only and

cannot be directly used as clinical treatment basis.

● Electromagnetic fields can affect the performance of the instrument, so

the use of other Instrumentsin the vicinity of the instrument must meet

the appropriate EMC requirements. For example, mobile phones, X-rays, or

MRI devices can all be sources of interference because they emit high-

intensity electromagnetic radiation.

● This is not a treatment device.

● After defibrillation, the recovery time of ECG is not more than 10s, and the

recovery time of other parameters is not more than 5s.

● To prevent burns to the patient when the monitor is used with a high

frequency surgical device, avoid any conductive connections between the

sensor and cable and the high frequency surgical device.

CAUTION

● To install or carry the instrument properly to prevent the instrument from

falling, colliding, being subjected to strong oscillations or other

mechanical external forces.

Page 10

Defibrillator Monitor S Series Service Manual

● Before the device is powered on, please confirm that the power supply

used meets the requirements of the instrument's nameplate label or the

power supply voltage and frequency specified in the instruction manual.

● When the instrument and accessories are about to expire, they must be

disposed of in accordance with relevant local laws and regulations or the

hospital's rules and regulations.

● Disposable accessories can only be used once, and repeated use can result

in performance degradation or cross-contamination.

● If the monitor will not be used for a long time, remove the battery and

keep it in a safe place.

● Defibrillation recovery time of less than 10s

PAY ATTENTION TO

● Install the instrument in a location that is easy to observe, operate, and

maintain.

● This instrument cannot be used at home.

● The instrument is limited to one patient at a time.

● The life of this monitor is 5 years.

Blood Oxygen

The oximeter is mainly used for the collection of blood oxygen signals,

amplification simulation, and conversion and processing of electrical signals.

During the monitoring process, the pulse amplitude of the optical signal also

changes. By calculation, blood oxygen parameters, pulse rate signals and volume waves

can be obtained. This data is then transferred to the main board via a special

communication protocol.

Chapter 6 Performance Verification

6.1 NIBP test

6.1.1 NIBP Air leak test

requirements：

 Adult non-invasive blood pressure cuff

 Suitable catheter

 Cylinder

Please follow the steps below to do the performance test:

1) Connect the cuff to the NIBP air vent of the monitor.

2) Wrap the cuff around a suitably sized cylinder.

3) Select [NIBP] in the parameter area, and select [Leakage Detection] in the [NIBP

Settings] menu that pops up.

4) At this time, “leakage detection...” will be displayed below the NIBP parameter area

on the screen, and the table system will start to perform air leak detection.

5) The system is automatically inflated to a pressure of 180 mmHg.

6) After about 20 seconds, the system will automatically open the bleed valve to mark

the completion of the leak measurement.

If there is no prompt information in the NIBP parameter area, the table shows that there

is no air leakage. If “Pump leak...” is displayed, there may be a leak in the gas path. At

this point, the operator should check whether the entire connection is loose. After confirming

that the connection is correct, perform another leak detection. If there is still a fault

indication, please contact the manufacturer for repair.

6.1.2 NIBP Pressure calibration

Figure 5

requirements：

 T-type interface

 suitable trachea

 ball type air pump

 Metal container: 500 ± 25 ml

 Sphygmomanometer (for reference): use a calibrated pressure gauge with an accuracy

greater than 1mmHg

Please follow the steps below to do the performance test:

1. Connect the monitor, pressure gauge, spherical air pump and metal container

(instead of the cuff) as shown in the figure below。

Figure 6

2. The pressure gauge reading should be zero before inflation. If it is not zero, open the ball pump valve

so that the entire gas path leads to the atmosphere, and then close the valve after the standard

pressure gauge reads zero.

3. In the [Monitor Maintenance] menu, select [User Maintenance], enter the password and enter the

[User Maintenance] menu, select [NIBP Check], and set the monitor to "Check" mode.。

4. The pressure in the metal container was inflated to 0, 50 and 200 mmHg by a ball type air pump.

The difference between the value of the standard pressure gauge and the pressure indicated by the

monitor should be within 3 mmHg. Otherwise, please contact the Comen service engineer.。

6.2 IBP test

Test requirements：

Invasive blood pressure simulator, IBP accessory.

Please follow the steps below to do the performance test:

1. Connect the invasive pressure simulator and monitor through the accessory, set the

output static pressure of the invasive pressure simulator to 0mmHg (0kPa), change

the current IBP channel pressure name in the monitor to ART and zero, the system

should prompt the school Zero success, and the average pressure value is also shown

as 0 mmHg (0 kPa).

Page 57

Defibrillator Monitor S Series Service Manual

2. Set the static pressure value of the artificial pressure simulator to 100mmHg, 200mmHg,

dynamic pressure value 120/80mmHg, the pressure display range of the current channel

should be (0~1mmHg, 98~102mmHg, 196~204mmHg, (118~122) / (79 ~ 81) mmHg).

3. Repeat the above steps for IBP channels 2, 3, and 4.

6.3 ECG test

Test requirements:

ECG lead, heart" simulator.

Please follow the steps below to do the performance test:

Use ECG lead and ECG simulator to connect one by one. After the ECG simulator is powered

on, press the “NSR” button of the ECG simulator to observe the HR value of the simulator

screen and the ECG waveform of the monitor. After stabilization, the HR value of the

instrument screen is ±1% or ±1bmp.

6.4 SpO

test

requirements requirements:

SPO2 probe

Please follow the steps below to do a performance test:

1. Connect the SPO2 probe to the monitor. Set the patient type to adult.

2. Test SPO2 on your finger. (assuming you are in good health)

3. Check the volumetric and pulse rate readings to ensure that the SPO2 value is in the

range of 95%-100%.

4. Remove the SPO2 sensor from your finger and the value and waveform gradually become

zero.
