The following diagram illustrates the structure of the patient monitor

2-4

2.3.1 Input System

Button board

The button board, located at the lower part of the monitor’s front panel, contains 6 keys and

provides connections for the following components to the main board:

 Knob
 Power switch & LED board
 Touchscreen control board
 Alarm LED board
 Inverter

The following diagram shows the button board connections.

Knob

The knob can be pressed, or rotated both clockwise and counter-clockwise. It is connected

with the button board.

Touchscreen

The touchscreen enables touch operations and can be calibrated. It is connected with the

touchscreen control board and main board.

Power switch & LED Board

The power switch & LED board controls the power supply for the main unit. It has three

LEDs, which respectively indicate the AC power status, battery status and monitor power

on/off status. It is connected with the button board.

2-5

2.3.2 Output System

LCD

The patient monitor adopts a high-resolution LCD. The LCD is connected with the main

board. The signals and power supply from the backlight board are transferred by the button

board.

Alarm Lamp

The patient monitor has two alarm lamps: alarm lamp and technical alarm lamp. Alarm lamp

lights either red or yellow whereas technical alarm lamp lights blue only. The alarm lamp

signals are transferred by the button board and are directly controlled by the main board

Recorder

The recorder receives data form 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 (It is

ON during normal working) on its front panel. It is connected with the mother board.

The following diagram shows its operating principle.

2-6

clock, EEPROM, etc. It interfaces to the mother board only, which then provides interfaces to

all other external devices.

2-8

The mother board is in charge of connections and communications with other components

and provides the following interfaces:

Name Description

LCD connector Connects the built-in display.

Video output +IO +IIC Connects the digital video interface board.

USB×2+network+RS422

+GPIO port

Integral Module Rack

The patient monitor has two kinds of integral module rack: 2-slot and 5-slot. The control

board includes a NIOS II FPGA. It implements protocol conversion and infrared

communication between the main unit and the parameter modules

The module rack communication board can be a 2-slot type or a 3-slot type. The 3-slot

communication board communicates the main board directly. The 2-slot communication

board is connected with and controlled by the 3-slot communication board. The 3-slot

communication board has the function of communication control. The 2-slot communication

board consists of the infrared circuit and module power circuit. The RS422 drive circuit is

located on the 3-slot communication board.

2-9

2.3.4 Power Management System

Battery

The patient monitor uses two chargeable lithium-ion batteries (11.1 V, 4500 mAh). The

battery compartment is located at the bottom of the patient monitor. The battery power is

supplied to the mother board via the battery interface board, and then to the power module.

Battery Interface Board

The Battery interface board connects the batteries to the DC input terminal of the power

module via the mother board, implementing charging and discharging of the batteries and the

power board.

Power Module

The power module is located at the back of the patient monitor. The main part of the power

module is the power board, which contains charging & power management board, voltage

drop DC transforming board and voltage rise and drop DC transforming board.

The power module converts the input power into DC power supplies and then distributes

them to each component of the patient monitor. The input power comes from either the

batteries or an AC source. The patient monitor will run power from the AC source whenever

an AC source is available. If the AC source becomes unavailable, the patient monitor will

automatically switch to the battery power. This does not affect the monitor’s operating status.

The power module protects itself and the patient monitor by switching off AC input or DC

output in case of overcurrent, short circuit and overvoltage. The power module provides 3

DC outputs:

Outputs Description

＋3.3 V

＋5.0 V

Power supply of the LCD, mother board, CPU board, DVI interface

board and integral module rack.

2.4 Parameter Module

Each parameter module may consist of the module infrared communication board, module

power board, module button board, parameter board, etc.

2.4.1 Module Infrared Communication Board

The module infrared communication board allows a short delay when powering up the

module and adopts FPGA to enable infrared communications between the module and the

module rack. An ID is integrated into the module infrared communication board. When a

module is inserted in the module rack, the ID is automatically sent to the module rack.

2.4.2 Module Power Board

Some modules have no power board. There are two kinds of module power board:

1. Isolated power board: converts the 12 V DC into a 12 V isolated DC and a 5 V isolated

DC.

2. Non-isolated power board: converts the 12 V DC into a 5 V DC

2.4.3 Module Button Board

There are keys and a LED on the module button board.

2.4.4 Parameter Board

The parameter board is a parameter measurement component, which is the most important

component of the parameter module.

2.5 SMR

The satellite module rack (SMR) is independent of the patient monitor. It provides 8 slots for

mounting parameter modules. It has the following features:

 It allows a parameter module to be plugged and unplugged with the patient monitor on.

This allows function extension and patient transfer.

 It does not have its own power supply. It is run by 12 V DC supplied by the patient

monitor and then supplies power supply to each parameter module via the contact

screws.

 It implements communication protocol conversions between the patient monitor and

each parameter module, provides infrared communications for parameter modules, and

is responsible for detecting infrared communications malfunction for each parameter

module.

The following diagram shows the structure of the SMR.

device can also be transmitted to the CMS or gateway. BeneLink module connects with the

external device through an ID module, which enables the information transmission between

the BeneLink module and the external device. BeneLink module can be connected to many

external devices such as anesthesia machine and ventilator.

In this chapter, patient monitor problems are listed along with possible causes and

recommended corrective actions. Refer to the tables to check the patient monitor, identify and

eliminate the troubles.

The troubles we list here are frequently arisen difficulties and the actions we recommend can

correct most problems, but not all of them. For more information on troubleshooting, contact

our Customer Service Department.

4.2 Part Replacement

Printed circuit boards (PCBs), major parts and components in the patient monitor are

replaceable. Once you isolate a PCB you suspect defective, follow the instructions in Repair
and Disassembly to replace the PCB with a known good one and check that the trouble

disappears or the patient monitor passes all performance tests. If the trouble remains,

exchange the replacement PCB with the original suspicious PCB and continue

troubleshooting as directed in this chapter. Defective PCB can be sent to us for repair.

To obtain information on replacement parts or order them, refer to Parts.
