1-1
1.1.2 Warnings WARNING
All installation operations, expansions, changes, modifications and repairs of this product are conducted by Mindray authorized personnel.
There is high voltage inside the equipment. Never disassemble the equipment before it is disconnected from the AC power source.
When you disassemble/reassemble a parameter module, a patient leakage current test must be performed before it is used again for monitoring.
The 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.
Dispose of the package material, observing the applicable waste control regulations and keeping it out of children’s reach.
1.1.3 Cautions CAUTION
Make 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.
Before 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.
Protect the equipment from damage caused by drop, impact, strong vibration or other mechanical force during servicing.

2 Operation Theory 2.1 Overview TheN22/N19 patient monitor provides rich functionality to monitor patient’s vital signs including ECG, Resp, SpO2, Temp, NIBP, IBP, CO2, AG, O2, RM, C.O., CCO, ICG, SvO2/ScvO2, BIS, EEG, NMT, tcGas and rSO2. Based on these parameters, the monitor supports alarm management, data review, recording and printing of patient reports, and calculation. TheN22/N19 patient monitor is applicable to various departments in a hospital, in particular, to the applications in intensive care, first aid, operation room and the relevant departments. The N22/N19patient monitor provides clinical decision-making tools to assist the medical personnel in making diagnosis and clinical judgment faster and more accurately. Information access to clinical information system can meet the information requirements of doctors and nurses so as to shorten the time of obtaining information and analyze the clinical experience. These features could better meet the application requirements of high-end users.
2.2 Product System Architecture N22/N19 monitor mainly consists of three parts: main unit, display and module rack. All-in-one installation or split-type installation could be adopted for the main unit and the display.

2.2.1 Functions of the Main Control Module The main board is supported by the Bay Trail platform and uses Intel’s Bay Trail-I E38xx series processors.
Architecture of the Main Board As the core control unit of the system, the main board is responsible for such core functions of the system as display, data processing and data storage. The main board also provides high-speed interfaces, such as USB connector, DP interface and network connector.
2-3
2.2.2 AC-DC Module The ACDC module converts the input voltage of 100~240V 50/60Hz AC into the output of 16V 10A DC.
2.2.3 Functions and Socket Definitions of the DCDC Board 2.2.3.1 Functions of the DCDC Board On the one hand, the DCDC board is responsible for the conversion of the data signal of the main board into the external interface; on the other hand, the DCDC board is responsible for generating the DCDC power supply of the hardware system and for implementing the power management function. The major functions include:
Generation and management of 12V, 5V, 3.3V, Vbus and 3.3VB power supply required for the system operation;
Extension of connectors such as SMR;
Monitor startup and shutdown;
Battery management;
2.2.3.2 Definitions of the DCDC Board Socket The DCDC board is the core for connecting other PCBAs inside the main unit, and the main sockets include:
16V DC input power socket used for connecting to the ACDC board Connector Type

2.2.4 Front Housing Interface Board The front housing interface board and its peripheral circuits are mainly used for realizing the control of the alarm LED, LOGO LED, backlight and audio, as well as the detection and transmission of the touchscreen, encoder and ambient light. As the front housing has too much to control, a MCU is used for the central control. The MCP is connected to the main control of the system through DP AUX, and the USB connection channel is reserved.
2.2.5 iView Substrate iView substrate is mainly used to carry the COME module, extending the function of the COME to standard interfaces as well as communication signals with the main board.
