The interface part has a USB HUB and supports two USB ports, networks, RS232, and such signal output as VGA signals and analog signals.

2.3.4 Main board

The main board includes the CPU, FPGA, FLASH, DDR-SDRAM, network controller, etc.

FPGA deals with displaying, sound and interface.

2.3.5 Recorder board

The recorder board consists of the CPU, drive circuit, feedback circuit and print head. It communicates with the main board through the UART.

2.3.6 CF board

The CF board functions by employing the USB-to-CF chip.

2.3.7 Wireless access point

The wireless access point enable the patient monitor to go wireless.

2.3.8 Key board

2-5

2.3.11 Multi-Parameter board

The Multi-parameter board is integrated with multiple parameters, such as ECG, RESP,

SPO2, IBP, NIBP, TEMP, etc. Refer to the following introductions for details.

„ The Multi-parameter board employs a high-speed DSP, making digital filtering, arrhythmia analysis and ST analysis faster and more effective.

„ The Multi-parameter board supports 3-, 5- and 12-lead ECG monitoring, arrhythmia and ST analysis, and has a good capability to resist electrosurgical unit interference and 50/60Hz frequency.

„ The Multi-parameter board supports 2-channel measurement of temperature.

„ The Multi-parameter board measures the respiration rate of patients using the impedance method, and can monitor the respiration rate with two ECG leads.

„ The Multi-parameter board is integrated with Mindray SpO2 circuit. If a monitor is configured with an OEM SpO2 module, the function of Mindray SpO2 is shielded.

„ The Multi-parameter board supports 2-channel measurement of IBP.

„

2.3.12 C.O. and IBP module

The C.O. and IBP module supports 2-channel measurement of IBP and C.O.. The module consists of an amplification circuit, AD converter, CPU circuit and power isolation circuit.

The signals amplified by the amplification circuit are converted to digital signals through the AD converter, which are then collected by CPU and sent to the main unit via an isolation coupler after being processed.

2.3.13 CO2 module

„ There are three types of CO2 modules: Mindray CO2, Microstream CO2 and

Mainstream CO2.

„ The Mindray CO2 module measures the concentration of CO2 using the NDIR technology. It zeroes periodically to ensure accurate measurements for a long period of time. Appropriate compensations can be made based on the operating environment, thus preventing measurements from being influenced by interfered gases.

„ The world-class Microstream CO2 module ensures measurements are not affected by other gases and can be obtained accurately without any gas compensation. Additionally, the module has a very low sample flow rate, reducing its maximum effects on the patient and the environment.

„ The world-class Mainstream CO2 module is compact and convenient for use. It adopts the power isolation technology of Mindray and thus meets the CF requirements of power isolation.

2-6

2.3.14 AG module

The AG module of ARTEMA can analyze multiple gases with the sidestream technology and is intended for anesthesia and intensive care. The infrared sensor of the module can measure 8 infrared lights of varied wavelength. The concentration of multiple gases can be calculated precisely through the nonlinear matrix algorithm.
