Using This Manual

z It is important for the hospital or organization that employs this equipment

to carry out a reasonable service/maintenance plan. Neglect of this may

result in machine breakdown or harm to human health.

z Never use combustible gas (e.g. anesthetic) or combustible liquid (e.g.

ethanol) around the analyzer. Otherwise, the risk of explosion may exist.

z When servicing the analyzer, be sure to turn off the power. Servicing the

analyzer when it is on may bring risk of electric shock or damage to

electronic components.

z Connect the analyzer to a socket having sole fuse and protective switch. Do

not use the same fuse and protective switch with other equipment (e.g. life

supporting equipment). Otherwise, the equipment failure, over current or

impulse current that occurs at the startup moment may lead to tripping.

z To prevent personal injury during mainten ance, keep y our clothes, hairs and

hands from the moving parts, such as sample probe, clipper and piercer.

z Possible mechanical movement of the warned position may lead to personal

injury during the normal operation, removal and maintenance.

z Be sure to dispose of reagents, waste, samples, consumables, etc.

according to government regulations.

z The reagents are irritating to eyes, skin and mucosa. Wear proper personal

protective equipment (e.g. gloves, lab coat, etc.) and follow safe laboratory

procedures when handling them in the laboratory.

z If the reagents accidentally spill on your skin, wash them off with plenty of

water and if necessary, go see a doctor; if the reagents accidentally spill into

your eyes, wash them off with plenty of water and immediately go see a

doctor.

customer service department for maintenance adv i ce.

z To prevent personal injury or damage to equipment components, remove

metal jewelry before maintaining or servicing electronic components of the

equipment.

z Electrostatic discharge may damage electronic components. If there is a

possibility of ESD damage with a procedure, then do that procedure at an

ESD workstation, or wear an antistatic wrist strap.

z This equipment must be operated by skilled/trained medical professionals.

z Samples, controls, calibrators and waste are potentially infectious. Wear

proper personal protective equipment (e.g. gloves, lab coat, etc.) and follow

safe laboratory procedures when handling them in the laboratory.

2 System Structure

2.1 System Overview

 Hardware

Hardware is designed for signal gathering, the controlling and driving of motion components

and the processing and display of data. It is mainly composed of main board, power drive

board, signal processing board, power board, blood sensor board and pressure sensor

board.

 Interfaces

BC-5800 offers many interfaces to facilitate data processing and selection of various

accessories. It provides 4 USB interfaces, 1 network interface, 1 pneumatic unit control

interface and 1 reserved interface. USB interfaces can be used to connect mouse, keyboard,

printer, scanner and USB, and to perform software upgrade. The network interface adopts

built-in network card, can perform networking function.

 Software running environment

System software can be divided into boot software, operation software and application

software. The boot software and operation software are stored in the FLASH chip of the main

board, and the application software is stored in the hard disk. The boot software has two main

functions, one is to configure address space, and the other is to initialize system memory.

The operation system completes the resource initialization of CPU board and provides

operation system environment to the application software. The application software offers an

interactive operation interface.

 Fluidic system

Fluidic system is the tubing structure of the analyzer where reagent, sample and air flow

through. All hydraulic parts are connected correspondingly, and they are controlled by

software and drive hardware according to the specified order to realize control over the

allocation and direction of media.

2.5 Software Structure

Software system can be divided into boot software, operation software and application
software. Boot software is autoloaded by hardware; its code runs in FLASH to configure
address space and to initialize system memory. Operation system completes the resource
initialization of CPU board, loading application software and transferring the CPU control
authority to application software. The code of application software runs in SDRAM, it obtains
the resource data needed from external hard disk to provide functions like counting,
parameter setting, quality control, device maintenance, data management, assistance, help,
etc. The application software sends control command to corresponding fluidic units at the
specified time according to the fluidic unit control sequence in basic sequence.

2.5.1 Menu Structure

1. Main screen
There are 8 function icons in the main screen menu. Operators can click on the function
icons in the main screen to enter into corresponding screens to perform all functions of the
analyzer. See Figure 2-9 fo r the submenu structure of the main screen.

Figure 2-9 Menu Structure of the Main Screen

2. Counting screen
Counting screen comprises four parts: status region, measurement result and data region of
the current sample, data display region of the next sample and function button region.
Operators can click each function button in the counting screen to perform the functions of
the analyzer.
