iView System
iView sytem includes iView mother board, computer board, hard disk and so on. iView
system connects to main control board, DVI interface board and USB interface board. The
iView system transmits the network signal to host network interface through DVI interface
board.
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 is 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.
2.3.4 Power Management System
Battery
The patient monitor uses two chargeable lithium-ion batteries (11.1 V, 4500 mAh). The
battery compartment door is located at the bottom of the patient monitor. The battery power
is introduced to the power module via the battery interface board, and then processed and
distributed to each component by the power module.
NOTE
z Two batteries must be used simultaneously when the patient monitor operates on
battery power. Otherwise, it may cause power supply protection.
