Mindray MEC1000 Patient Monitor – troubleshooting, beep error descriptions
MEC-1000 is a flexible, portable
patient monitor. MEC-1000 can monitor physiological signals including ECG,
RESP. Rate, NIBP, SpO2, and TEMP. MEC-1000 can convert these physiological
signals into digital signals, which can be further processed and used to judge
whether to trigger alarm. The user can control the operation of MEC-1000 via
using the buttons on the front panel. MEC-1000 can be connected to the central
monitoring system via the Mindray network so as to form a network monitoring
system.
MEC-1000 uses ECG electrodes, SpO2
finger sensor, blood pressure cuff and temperature probe to measure the
physiological signals including ECG, NIBP, SpO2, TEMP and RESP Rate. In the
process of measurement no energy or substances are extracted from and/or
delivered to the patient with the exception that sine wave signals are
delivered to the patient during measuring RESP Rate. MEC-1000 converts the
acquired physiological signals into digital signals, waveform and numerical
values and displays all information on the screen. The user can also control
the operation of the monitor via using the buttons on the front panel. The user
can set alarm limits for each parameter. In this way once finding a
physiological parameter exceed the pre-set alarm limits, MEC-1000 will activate
its visual and audio alarm (the numerical display flashes or lights on) in
order to raise the user’s attention.
During treatment, it is highly
important to continuously monitor the vital physiological signs of the patient
to transmit the important information. Therefore patient monitor has always
been occupying a very important position in the filed of medical devices. The
continuous improvement of technologies not only helps us transmit the vital
physiological signs to the medical personnel but also simplifies the
measurement and as a result raise the monitoring efficiency. For inpatients, we
need to measure those vital cardiac and pulmonary signs such as ECG, SpO2,
blood pressure and TEMP, etc. In recent years, the technological improvement
pertaining to measurement and information transmission has led to more
comprehensive performance and stable quality of the patient monitoring
products. In the past, the dominant products manufactured by medical device
manufacturers are mainly those for single parameter measurement. Nowadays
however multi-parameter patient monitors are more widely and commonly used.
MEC-1000 patient monitor can measure
physiological signals including ECG, RESP., NIBP, SpO2 and TEMP. It can convert
these physiological signals into digital signals and further display them on
the screen. The alarm limits can be user-defined. Once finding a parameter
reach or exceed its pre-set alarm limits, MEC-1000 can automatically activate
the corresponding alarm. In addition, the user can operate the monitor by using
the buttons on the front panel. In addition to outpatient department, monitors
are generally used in some clinical areas such as ICU, CCU, operation room and
emergency room because the monitor
can provide many other physiological parameters of the patient to medical
personnel. Only the qualified medical personnel shall use MEC-1000 patient
monitor.
MEC-1000 Principle
MEC-1000
portable patient monitor has been designed to measure physiological
parameters including ECG, RESP, TEMP, NIBP and SPO2, etc. Figure below
shows the structure of the whole monitor as well as the connection
relationships between different parts. The board in the center of the
figure is the core part of the monitor, i.e., integrated board for main
control and parameter measurement, which, though being a single board,
could realize the measurements of five said parameters; accordingly
uniform AD conversion and digital processing system is used.
MEC-1000 is made up of following
parts
1) Parameter measurement part
2) Main control part
3) Man-machine interface
4) Power supply
5) Other auxiliary part

Troubleshooting
System alarm prompt table
Back display with white or blurring screen
1) Check if TFT connecting wire is well contacted;
2) If changing connecting wire cannot solve the problem, replace the TFT screen;
3) If fault still exists, replace the main control board.
Encoder fault
1) If other functions of the keypad run correctly (indicator, alarm light and key), go to the
second step; otherwise, replace the keypad;
2) Check if the bonding pad of the encoder is short-circuit connected or abnormal open circuit;
3) Replace the encoder.
No alarm sound
1) Check if the sound is switched off in the software setups;
2) Replace the speaker;
3) Replace the keypad.
Can not print
1) Check if the software has alarm related to recorder; if yes, remove the corresponding
alarm;
2) Check if the indicator of the recorder is lighted on;
3) If not, check the connecting wire of signal input of the recorder;
4) Check if the recorder module is set to ON in the MAINTAIN menu;
5) Check the connecting wire of the power input of the recorder (including power board of the recorder);
6) Replace the recorder.
Abnormal paper feeding
1) Check if foreign objects are attached to the paper bail of the recorder;
2) Check if foreign objects are attached to the gears of the thermal head of the recorder;
3) Check if the power voltage of the recorder is >7.8V.
