Chapter 15 Maintenance
I
n case of trouble of this machine in the service, follow the instructions below to eliminate the problem first. If the
attempt fails, refer to the dealer in your local area or the manufacturer. Refer to the detailed provisions in contract for the
warranty period of the main unit and the accessories of this monitor.
15.1 Daily Examination
Before using the monitor, the checks below should be carried out:
Check the monitor for any mechanical damage;
Inspect the exposed parts and the inserted parts of all the cables and the accessories;
Examine all the functions of the monitor that are likely to be used for patient monitoring, and ensure that it is
in good working condition;
Make sure that the monitor is grounded properly.
Pay close attention to the fluctuation of the local power supply voltage. A power voltage regulator is
recommended when necessary.
In case any indication of damage about the function of the monitor is detected and proven, it is not allowed to apply it to
the patient for any monitoring. Please contact the local dealer or our company, and we are to offer the best solution as
soon as possible for your satisfaction.
15.2 Routine Maintenance
At each routinely maintenance or the yearly maintenance, the monitor can be thoroughly inspected by qualified
personnel, including performance and safety examinations. This monitor is designed with life cycle of 5 years. It is strongly
recommended to use the product which is still within its life cycle, or it may cause inaccurate measurement. In order to
ensure its long service life, please pay attention to the maintenance.
If the hospital fails to carry out a satisfactory maintenance program about the monitor, it may get disabled and
harm the patient’s safety and health.
Perform protective grounding impedance, leakage current and insulation resistance test.
In case of ECG cable/lead wires damage or aging, please replace the cable or lead wires.
If there is any indication of cable and transducer damage or they deteriorate, they are prohibited from any further
use.
The Monitor is calibrated in the factory before sale, so there is no need to calibrate it during its life cycle. Any patient
simulators should not be used to validate the accuracy of blood pressure and oxygen saturation measurement,
they can only be used as functional testers to verify its precision.
The accuracy of ECG signal amplification can be verified by the built-in 1mV calibration signal.
The accuracy of pressure measurement and air leakage in pneumatic system can be verified by means of the built-
in pressure verification function and a precision pressure meter, please refer to the related chapter in Part 2 of
the user manual for detail operation.
The SpO
2
simulator can not be used to verify the SpO
2
measuring accuracy, which should be supported by the clinical
study conducted by inducing hypoxia on healthy, non-smoking, light-to-dark-skinned subjects in an independent
research laboratory. However it is necessary for the user to use SpO
2
simulator for routine verification of precision.
Please note that the specific calibration curve (so called R-curve) should be selected when use of SpO
2
simulator,e.g.
for Index 2 series SpO
2
simulator from Fluke Biomecidal Corporation, please set “Make” to “DownLoadMake:
