Main Board

The main board is the control center of the equipment. It provides communication and display functions, including:

Communication with SpO2 board, and NIBP module through serial ports, starting parameter measurement, and reading measured results;

Communication with Predictive/IR (Infrared Radiation) Temp module through serial ports;

Communication with power management board through serial ports;

Extending an RS232 serial port;

Control over the Segment-code LCD display through I2C;

Providing backlight drive for segment-code display;

Recognition of keypad actions, and providing corresponding response;

Control over the beeper through IO port; and,

Providing 24 hour timing via the inner RTC.

Keypad

The keypad consists of elements like keypad and AC/Battery indicator etc.

2.5 Rear Housing Assembly

Power management

and interface board AC/DC power module

SpO2 board

Battery compartment

NIBP module

Rear housing assembly consists of power module (AC/DC), power management and interface board (including SpO2 isolation power), battery compartment, NIBP module, and SpO2 board (including three types of configuration, i.e. Mindray, Masimo, and Nellcor).

AC/DC Power Module

The AC/DC power board transforms the input AC into DC power, which is the power source for all voltages in the equipment.

Power management and interface board

The power management interface board mainly provides the following functions:

Charge and discharge of battery and charge detection;

DC/DC conversion: outputs 12V and 5V DC power;

Control over power On/Off key and AC, BAT indicator;

Communication transmission among parameter modules;

2-4

Providing isolation power for Mindray/OEM SpO2 module; and,

Providing external connectors, and also filter and protection for these connectors.

NIBP Module

The NIBP module consists of blood pressure measurement board and pump and valve assembly, providing measurement acquisition of blood pressure data. The main functions of the NIBP module are:

NIBP measurement; and,

Data exchange with the main board through the serial ports.

SpO2 board

The independently developed Mindray SpO2 board provides SpO2 measurement as good as other boards but with smaller size and lower consumption. The power management and interface board is also compatible with Nellcor NELL-1 SpO2 board and Masimo MS-2013 SpO2 board.

The SpO2 board collects SpO2 signals, processes SpO2 algorithm and sends measurement results to the main board. The power management interface board provides isolation power for it.

2.6 External Module

An external Temp module can be extended on the monitor.

The independently developed Mindray Temp module consists of an isolation power board, Temp measurement board, and probes. The Temp measurement board collects Temp signals, processes algorithm and sends measurement results to the main board.
