There are Six groups of 7-segment digit display on the key&displays board. They are used for
displaying the systolic pressure, diastolic pressure, mean pressure/cuff pressure, SpO
, PR
2
and Temp; every group is of 3 digits.
The signal is transmitted from the main board FPGA to the CPLD, and is displayed by the
7-segment digit displays driven by the CPLD scanning.
The AC indicator is driven by the ADV voltage output from the power board.
The working status indicator (ON/STADNDBY indicator) is driven by the 3.3V voltage.
The battery indicator is controlled by the flash control signal, ADV signal and /BC signal
together. When the system is powered by the battery only, the CPLD outputs the flash control
signal and the battery indicator flashes; when the system is power by AC mains, the ADV
voltage drives the battery indicator to ON. The /BC signal is transmitted from the power board
to the cathode of the battery indicator. When there is no battery in the monitor, the resistance
of the /BC becomes high, so the battery indicator will never become ON.
The bichrome LED alarm indicator is driven by the 3.3V voltage and controlled by the flash
control signal output from the CPLD.
For other LED indicators, the anodes are co nnected t o 3.3V voltages and are controlled by the
CPLD I/O port.
The displaying and controling is signal of the indicators above is delivered from the main board
FPGA to the CPLD.
2.2.3.2.3 Keys
There are totally 12 keys.
ON/STANDBY key: In the OFF status, press this key to power on the monitor; in the working
status, press this key for less than 1s to enter the standby status. Press this key for more than
2s to power off the monitor.
The other 11 keys form a 3×4 matrix. The CPLD scans the key matrix, and performs the key
debouncing after detecting any key input signal. If the input signal is valid, the CPLD saves the
current key input code and transmits it to the main board.

2-10
Principles of Operation
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.

The NIBP signal is the differential input signal. The difference amplifying circuit amplifies the
dual-end difference signal and converts it to the single-end signal; meanwhile, this circuit
sends a channel of signal to the A/D conversion part, and the other to the DC isolating and
amplifying circuit.
The DC isolating and amplifying circuit removes DC components from the signal, amplifies the
signal, and then sends it to the A/D conversion part.

The A/D conversion part converts the analog signal to the digital signal, and sends it to the
CPU System for further processing.
2.2.5.2.5 Over Pressure Detect
The circuit detects the NIBP pressure signal. Once the pressure value exceeds the protected
pressure value, it will send a message to the CPU System, which asks the Valve Drive Circuit
to open the valve to deflate the cuff.

2.4 System Parameters
2.4.1 NIBP
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. Then, the pulsation
signal is filtered by a high-pass filter (about 1Hz), amplified, converted to the digital signal by
2-17
Principles of Operation
the A/D converte r, and finally processed by the MCU. After that, the systolic pressure, diastolic
pressure and mean pressure can be obtained. For neonates, pediatric and adults, it is
necessary to select the cuffs of a proper size to avoid possible measurement errors. In the
NIBP measurement, there is a protection circuit used to protect patient from over-high
pressure.
The NIBP measurement modes include:
1) Adult/pediatric/neonate mode: To be selected according to the build, weight and age of the
patient;
2) Manual/Auto/Continuous mode: The manual measurement is also called single
measurement; in this mode, only one measurement is done after being started. In the auto
measurement mode, the auto measurement be done according to the preset procedure. In the
continuous measurement mode, quick continuous measurement will be done within 5 minutes
after being started; it detects the changes in blood pressure effectively.
2.4.2 SpO2
The SpO2 value is obtained through the pulse waves of the finger tips based on specific
algorithm and clinical data. The SpO
LEDs and an inbuilt light receiver. The two LEDs include one red-light diode and one infrared
diode, which emit light in turns. When the capillaries in the finger tip are iteratively congested
with blood pumped by the heart, the light emitted by the LEDs, after absorbed by the
capillaries and tissue, casts on the light receiver, which can sense, in the form of electric signal,
the light strength changing with the pulsated blood. The DC/AC ratio of the two photoelectric
signals corresponds to the content of the oxygen in the blood. Therefore, the correct pulse
oxygen saturation can be obtained with specific algorithm. Moreover, the pulse rate can be
obtained according to the pulse waveform.
The circuit of the SpO
module is involved in four parts: SpO2 probe, signal processing unit,

LED-driven sequencing control part and the MCU.
probe is the measurement transducer. It has two inbuilt

Principles of Operation
2.4.3 TEMP
Body temperature can be taken with two different methods according to the temperature probe
used. One method is direct measurement with which the temperature is measured by thermal
equilibrium. Therefore, thermistor, platinum resistance or mercury can be used in the temperature
probe. Direct temperature measurement is the standard method for measuring body temperature
and it is commonly used for clinical diagnosis. With this method, we can obtain accurate
temperature reading, however, it takes longer time since we need time for reaching thermal
equilibrium. Another temperature measuring method is indirect, which uses thermal radiation of
human body to obtain body temperature. Thus, the probe can be an infrared sensor. Indirect
temperature measurement takes shorter time but the measurement error is greater
Direct temperature measurement can be classified as continuous monitoring and predictive
measurement. Continuous monitoring thermometer continuously monitors body temperature and
displays the temperature reading in real time by applying the temperature probe to the measured
site. Since it takes time for heat conduction between the human body and the thermometer,
continuous monitoring takes relatively longer time to reach the final temperature, normally 3
minutes in oral mode and 5 minutes in axillary mode. In predictive thermometer, a heating device
is connected with the temperature detector. Time for reaching the thermal equilibrium between the
temperature probe and the measured site is shortened with the heating device before temperature
measurement. Additionally, the temperature at which thermal equilibrium is reached is predicted
according to the temperature curve of the probe in given time. Since the final temperature of the
measured site can be obtained without taking time for reaching the thermal equilibrium, measuring
time can be shortened effectively.
The predictive TEMP mode provide both continuous monitoring (in MONITOR mode) and
predictive measurement (in PREDICT mode).

blood pressure 255/195/215 mmHg, SHIFT +15 and HR 80BPM, and the VS-800 to the
ADULT mode. Press START for around 30 seconds, and the results will be calculated.
The test results are 270±8mmHg, 210±8mmHg and 230±8mmHg.
2. Press ECS and↓ on the simulator to enter the NEONATE mode. Set the simulator to the
blood pressure 120/80/90 mmHg and HR 120 BPM, and the VS-800 to the NEONATE
mode. Press START for around 30 seconds, and the results will be calculated. The test
results will be 120±8mmHg, 80±8mmHg and 90±8mmHg respectively.
3. Press ESC and ↓ on the simulator to enter the NEONATE mode. Set the simulator to the
blood pressure 60/30/40 mmHg, SHIFT—20 and HR 120 BPM, and the VS-800 to the
NEONATE mode. Change the simulator accessory to a neonatal cuff. Press START for
around 30 seconds, and the result displayed should be 40±8mmHg, 10±8mmHg and
20±8mmHg.
