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.

2Operation 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.

The main PCBAs of the system include:
Main unit: DCDC and interface board, ACDC board, and main board and interface board.
Display: display interface board
Module rack: Module rack interface board, and 8-slot module rack communication board.

2-3
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.

2-4
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
