2 Theory of Operation 2.1 Introduction This patient monitor is intended to be used for monitoring, displaying, reviewing, storing and transferring of multiple physiological parameters including ECG, respiration (Resp), temperature (Temp), SpO2, pulse rate (PR), non-invasive blood pressure (NIBP), invasive blood pressure (IBP), cardiac output (C.O.), End tidal CO2 value (EtCO2) and anesthetic gas (AG) of single adult, pediatric and neonatal patients. C.O. monitoring is restricted to adult patients only.
The patient monitor also:
Provides audible and visual alarm indications in case of patient or equipment problems.
Enables displaying, reviewing, storing and transferring of real-time data.
Incorporates multiple input devices such as buttons, knob and touchscreen
Enables program upgrade over the network.

2.2 System Connections 2.2.1 Mounting the Patient Monitor The patient monitor can be mounted on a wall bracket or on a trolley support. The wall bracket or trolley support can be ordered optionally. Each type of mounting bracket is delivered with a complete set of mounting hardware and instructions. Refer to the documentation delivered with the mounting hardware for instructions on assembling mounts.
CAUTION z
Use mounting brackets we supply or approve. If other compatible mounting bracket is used, be sure it can be safely used on the patient monitor.
z
The mounting bracket should be installed by our qualified service personnel, or engineers who have adequate knowledge on it.
z
If other mounting solution is used, the installation personnel and the customer should verify if it can be safely used on the patient monitor, and the customer assume the responsibility for any risk resulting from that.

2.3 Main Unit The following diagram illustrates the structure of the patient monitor.
The functional modules/parts of the main unit are described in the following sections.
2.3.1 Power board (AC/DC) The power board switches AC power to DC power as the output.
2.3.2 Battery interface board The battery interface board introduces battery power to the internal system. The patient monitor can also be powered by rechargeable li-ion or lead-acid battery.
2-4
2.3.3 Power management and interface board This board is responsible for power management and interfaces. Power management can perform the functions below: 1. Outputting 12V, 5V, and 3.3V DC power 2. Power On/Off control 3. Charge/Discharge control 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 The key board consists of the Power button, keyboard scanning circuit, and AC/battery indicators.
2.3.9 Touchscreen board The touchscreen board controls the touchscreen and passes the control signals to the main board.
2.3.10 Alarm LED board The alarm LED board consists of the red LED and yellow LED.
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.
