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.

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 HyperVisor 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 Installation Support 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 z
Use mounting brackets we supply or approve. If other compatible mounting bracket is used, be sure it can be safely used on the patient monitor.
z
The mounting bracket should be installed by our qualified service personnel, or engineers who have adequate knowledge on it.
z
If 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 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 SpO2 stacking board, CO2 module, and IBP/C.O. module.
The following figure shows the main unit architecture of the patient monitor.

2.4.1 Main Board The main board is located at the center of the front housing assembly's LCD metal sheet. It is the heart of the patient monitor. It provides communication, display, and data storage functions, including:
Display drive and backlight control
Wired and wireless network
Data storage (DDR, NOR flash, and SD card)
Printing
Serial ports: there are 7 serial ports, respectively for multi-parameter module, C.O./IBP module, sidestream/mainstream CO2 module, recorder, power board, and key board. The seventh serial board is for future use.
Connection with touchscreen control board
Audio drive

The main board has the following interfaces to connect other PCBAs:
Display signal interface
Backlight control interface
Keypad interface
Alarm lamp interface
Wi-Fi interface
SD storage card interface
Interface board interface (for external output, module communication, power supply and etc.)
2.4.2 Keypad and the Navigation Knob The keypad and navigation knob are located at the right side of the front housing assembly. The navigation knob can be rotated both clockwise and counterclockwise. It can also be pressed down. The navigation knob is connected with the keypad. The keypad has the following functions:
It scans and detects the input of the six keys;
It integrates the power on/off hardkey;
It integrates the rotary encoder;
It connects and forwards the status of power switch and LED board to the main board; and,
It communicates with the main board through a serial port.
The following figure shows the connection of keypad:
2-6
2.4.3 Power On/Off and LED Indicator Board The power on/off and LED indicator board is connected with the keypad. It controls the patient monitor's power switch. It has 3 groups of indicators which are used to indicate the status of AC mains, battery, as well as the monitor's power on/off status.
2.4.4 Alarm Lamp Board The alarm lamp board is located at the top of the front housing. It has two-color indicators, red and yellow. The alarm lamp board directly connects the main board through a cable. It is controlled directly by the main board.
2.4.5 Display iMEC8, iMEC10 and iMEC12 respectively support 8-inch, 10-inch, and 12-inch LCDs. The display connects the main board through a display signal cable and a backlight cable. The interface cables for the three types of patient monitors are different and cannot be mixed. The reliability of display signal cable is relatively poor. If display problem occurs, consider first to replace the display signal cable.
2.4.6 Touchscreen and Touchscreen Control Board The fully configured iMEC patient monitor supports touchscreen. The touchscreen can be controlled by touch and can be calibrated. The touchscreen is connected with the touchscreen control board and the main board. The touchscreen control board drives the touchscreen and implements communication with the patient monitor. The touchscreen control board communicates with the main board via an I2C interface and connects the touchscreen via FPC.
