The core of the system is the main board which provides power supply for all parameter modules. The parameter modules directly communicate with the main board, and the measurements and status of all modules are processed by the main board and then displayed on the key&display board. The main board also controls communication with the speaker, the recorder and all the external connectors.

2.3.1 Main Board
The main board provides resources and supports for the overall system. It controls LCD,
LED, keyboard, speaker and recorder. It also enables to communicate with parameter modules and connectors.

2.3.1.2 Function Description
The main board communicates with all the parameter modules and the recorder through
FPGA extended serial port.
The main board supplies information through FPGA for the key&display board to display; it detects the keys and implements user interface.
The main board controls the alarm indicator via FPGA and the signal wire is adapted from key&display board.
The main board controls the speaker to give audible alarm, key tones and Pitch Tone.
The main board provides nurse call connector, network connector and R232 connector.
The real-time clock is implemented by the RTC chip. The RT clock is powered according to the priority of AC mains, battery, and button cell on the main board. This ensures the normal working status of the clock in the event that AC mains and batteries are not available.
SDRAM is responsible for storing data temporarily and running programs. Flash serves as the system memory and trend data memory whereas EEPROM services as the device configuration memory.

2.3.2.2 Functions
After the AC input reaches the power board, it flows through the EMI filter circuit and rectifier and filter circuit. Then it is converted to a DC voltage, which is further converted to the 16.8V DC voltage by the Flyback converter. The 16.8V DC voltage is the main input of
DC/AC converter and charging circuit; it is used to charge the lithium battery or lead-acid battery, and also converted to 12V, 5V and 3.3V DC voltage by corresponding circuit conversion. In case the AC input is unavailable, the battery can supply power for the DC/DC converters to get 12V, 5V and 3.3V DC voltages, which are under the control of device poweron/poweroff signal.
The 16.8V DC output is protected against over-voltage and over-power, the 12V and 3.3V
DC outputs are protected against over-voltage, short-circuit and over –current, the 5V DC output is protected against over-voltage and short-circuit.
Two power boards are developed for the lead-acid battery and lithium battery. Each board demonstrates the battery types it supports via the main board connector, facilitating the main unit to process information such as battery capacities. The power board charges the battery merely under AC input. The monitor runs on AC mains if both AC mains and battery are available.

, PR, Temp and so forth.
The AC indicator is driven by the ADV output from the power board whilst the working status indicator (built in the Power On/Off key) is driven by 3.3V voltage. The battery indicator is jointly controlled by the flash control signal, ADV signal and /BC signal.
The keypad consists of the power ON/OFF key and the other 11 functional keys.

The NIBP is measured based on the pulse vibration principle. Inflate the cuff which is on the forearm till the cuff pressure blocks the arterial blood, and then deflate the cuff according to a specified algorithm. While the cuff pressure is decreasing, the arterial blood has pulses, which are sensed by the pressure transducer in the cuff. Consequently, the pressure transducer connected with the windpipe of the cuff, generates a pulsation signal, which is then processed by the NIBP module to get the NIBP value.
NIBP values are based on the oscillometric method of noninvasive blood pressure measurement and correspond to comparisons with auscultative values (applied to adults and pediatrics elder than 3 years) and intra-arterial values (applied to neonates and pediatrics younger than 3 years) within ANSI/AAMI SP10 Standards for accuracy (a mean difference of
± 5 mmHg, and a standard deviation of < 8 mmHg).
2-8
2.3.4.3 Temp Module
The principle diagram of Temp module is shown below:
Normally, the sensor used for measuring temperature is a thermistor. The resistance of a given thermistor is nonlinearly relative to the temperature. Thus, the resistance of a thermistor can be conversed into temperature. By applying given field current to the thermistor, its resistance can be easily obtained by measuring the voltage on the thermistor.
2.3.5 Recorder
The recorder receives data from the main board and then sends them to the thermal printhead for printing. The recorder has a hardkey(starting/stopping recordings) and a green LED on its front.
2.3.6 Bar Code Scanner
The bar code scanner enables to read the one-dimensional and two-dimensional bar codes, simplifying patient admit. The bar code scanner communicates with the monitor and gets power supply to the power source via the serial ports. The scanner’s serial port is defined as follows:

3.6 Electrical Safety Tests
WARNING
z Electrical safety tests are a proven means of verifying the electrical safety of the
monitor. They are intended for determining potential electrical hazards. Failure to find out these hazards timely may cause personnel injury.
z Commercialy available test equipment such as safety analyzer can be used for
electrical safety tests. Be sure that the test equipment can be safely and reliably used with the monitor before use. The service personnel should acquaint themselves with the use of the test eqipment.
z Electrical safety tests should meet the requiremnets of the latest editions of EN
60601-1 and UL60601.
z These electrical safety tests do not supercede local requiremnets. z All devices using the AC mains and connected to medical equipment within patient
environments must meet the requiremnets of the IEC 60601-1 medical electrical systems standard and should be put under electrical safety tests at the frequency recommended for the monitor.
Electrical safety tests are intended to timely check the potential electrical hazards to the patient, operator or service personnel arising from the equipment. Electrical safety test should be performed under normal ambient conditions of temperature, humidity and atmospheric pressure.
The electrical safety test plan described hereunder takes 601 safety analyzer as an example.
Different safety analyzers may be used in different areas. Be sure to choose applicable test plan.
