1.1.1 DANGER
There are no dangers that refer to the product in general. Specific “Danger” statements may
be given in the respective sections of this manual.
1.1.2 Warnings
WARNING
zAll installation operations, expansions, changes, modifications and repairs of this
product are conducted by Mindray authorized personnel.
zThere is high voltage inside the equipment. Never disassemble the equipment
before it is disconnected from the AC power source.
zWhen you disassemble/reassemble a parameter module, a patient leakage current
test must be performed before it is used again for monitoring.
zThe equipment must be connected to a properly installed power outlet with
protective earth contacts only. If the installation does not provide for a protective
earth conductor, disconnect it from the power line and operate it on battery power,
if possible.
zDispose of the package material, observing the applicable waste control regulations
and keeping it out of children’s reach.
1.1.3 Cautions
CAUTION
zMake sure that no electromagnetic radiation interferes with the performance of the
equipment when preparing to carry out performance tests. Mobile phone, X-ray
equipment or MRI devices are a possible source of interference as they may emit
higher levels of electromagnetic radiation.
zBefore connecting the equipment to the power line, check that the voltage and
frequency ratings of the power line are the same as those indicated on the
equipment’s label or in this manual.
zProtect the equipment from damage caused by drop, impact, strong vibration or
other mechanical force during servicing.

2 Theory of Operation
2.1 Introduction
This patient monitor is designed to monitor a fixed set of physiological parameters including
ECG, respiration (Resp), temperature (Temp), SpO2, pulse rate (PR), non-invasive blood
pressure (NIBP), invasive blood pressure (IBP), cardiac output (C.O.), and carbon dioxide
(CO2).
The patient monitor also:
Provides audible and visual alarm indications in case of patient or equipment problems.
Enables displaying, reviewing, storing and transferring of real-time data and wave.
Incorporates multiple input devices such as buttons, knob, and touchscreen.
Enables program upgrade over the network.
Integrates the information of other devices, which include but are not restricted to
defibrillator.

2-2
The above figure shows a system consists of the iMEC patient monitor and its peripheral
devices. The iMEC patient monitor:
Can be used for monitoring the physiological parameters, giving alarms and reviewing
patient data, etc.
Supports recorder.
Supports nurse call signal, synchronization defibrillation signal, and analog output
signal.
Supports Wi-Fi module, wired network, remote view, and communication with the
Hyper Visor Central Monitoring System.
Supports a secondary display.
Supports external AC power source and an internal battery.
Supports clinical data acquisition, which has two ways: by SD card and by USB drive.
The system software should support data output function, for SD card is a built-in
device.
2.2 System Connections
2.2.1 Mounting the Patient Monitor
The patient monitor can be mounted on a wall bracket or on a trolley support. The wall
bracket or trolley support can be ordered optionally. Each type of mounting bracket is
delivered with a complete set of mounting hardware and instructions. Refer to the
documentation delivered with the mounting hardware for instructions on assembling mounts.
CAUTION
zUse mounting brackets we supply or approve. If other compatible mounting
bracket is used, be sure it can be safely used on the patient monitor.
zThe mounting bracket should be installed by our qualified service personnel, or
engineers who have adequate knowledge on it.
zIf other mounting solution is used, the installation personnel and the customer
should verify if it can be safely used on the patient monitor, and the customer
assume the responsibility for any risk resulting from that.

2-3
2.2.2 Connectors for Peripheral Devices
On the back of the patient monitor you can find all connectors for peripheral devices.
Figure 1 iMEC Rear View
1. AC Power Connector: used to connect an AC power source (100 to 240 VAC, 50/60Hz).
2. Equipotential Terminal used to connect the equipotential terminal of other equipment,
eliminating potential difference between different pieces of equipment.
3. VGA Connector: used to connect a secondary display.
4. Network Connector: It is a RJ45 connector used to connect an ethernet network or a PC.
5. Multifunctional Connector: used to output analog signals and defibrillator
synchronization signals.
6. General USB Connector: used to connect any USB-compatible peripheral device.

2.3 Main Unit
The main unit of the patient monitor consists of two parts:
Front housing assembly: main board, keypad board assembly (knob), display,
touchscreen, alarm lamp board, power switch and indicator board.
Rear housing assembly: power board (AC/DC), battery pad, interface board, recorder,
speaker, multi-parameter module which includes three types of SpO2stacking boards,
CO2module, IBP/C.O. module.
The following diagram illustrates the structure of the patient monitor.
