CHAPTER 1 INTRODUCTION1.1 GeneralMMED6000DP is a Portable Patient Monitor that has abundant monitoring functions and is used for the clinical monitoring of adult, pediatric and neonate. Besides, the user may select the different parameter configuration according to different requirements. MMED6000DP can be connected to the central working station to form a network monitoring system. MMED6000DP can monitor vital signals as ECG, RR, SpO2, PR, NIBP, TEMP, Dual-channel IBP (optional), CO2 (optional). It integrates parameter measuring modules, display and recorder in one device, featuring in compactness, lightweight and portability. Large true color display provides clear view of 6 waveforms and full monitoring parameters.

This symbol indicates that the instrument is IEC 60601-1 Type CF equipment. The unit displaying this symbol contains an F-type isolated (floating) patient applied part providing a high degree of degree of protection against shock, and is suitable for use during defibrillation. This item is compliant with Medical Device Directive 93/42/EEC of 14 June 1993, a directive of the European Economic Community.

1.4 Special Features Portable, compact, AC power and internal rechargeable battery; Automatically and rapid charge, 80-90% power will be recharged within 3 hours; Resistant high-frequency electrotome design, reliable and special module is used in operation room; Optional inner printer with 3 channels wave or external printer; Adjust volume more accurately by digital system; Menu design adopts Huffman decode, operating more effectively; Support Ethernet, wireless LAN and could connect with Central monitoring system.


1.5 Appearance of Monitor1.5.1. Screen display 4 channels

Fig.1-1

The display of MMED6000DP patient monitor is TFT LCD, which displays the patient parameters, waveforms, historical data and monitor status. The screen is divided into five areas: (1) monitor status, (2) waveforms, (3) the table of historical data, (4) parameters (5) menu as well as (6) frame of menu status.


Fig. 1-2

Monitoring status frame Bed No.: indicates the bed number of the patient being monitored when the patient monitor is connected with the workstation. DEMO: indicates the device is in DEMO monitoring mode now. In clinical application, this function is not recommended because the DEMO will mislead the hospital workers to treat the waveform and parameter as actual data of the patient, which may result in delay of treatment or mistreatment. Start time: indicates the time powered on the monitor, it shows in 16:25. Current time: indicates the current date and time, it shows in 05/16/2004, 10:10

Waveforms displaying area The waveform area can maximally display 6 waveforms. The colour of waveforms matches with the parameters on the right of the screen. For the maximum configuration, the waveforms provided by the system for selection are (from up to bottom): 2-lead ECG waveforms SpO2 waveform RESP waveform There are two means to gain RESP waveform, trans-thoracic impedance and Et-CO2 (optional). If operator selects Et-CO2 (side stream) to monitor the patients respiration, the CO2 waveform will instead of the RESP waveform acquired by Trans-thoracic impedance. 2 IBP waveforms(option) If operator selects IBP operation, the table of historical data will be instead of 2 IBP waveforms.


Numeric displaying area The parameter area lies to the right side of the graphic area, which includes: ECG: heart rate (unit: beats/minute) NIBP: from left to right, there are Systolic pressure, Mean pressure and Diastolic pressure (unit: mmHg or kPa) IBP: the BP of channel 1 and 2. From left to right, there are Systolic pressure, Mean pressure and Diastolic pressure (unit: mmHg or kPa) SpO2: SpO2(unit: %) pulse rate (unit: beats/minute) RESP: respiration rate (unit: breaths/minute) TEMP: temperature of channel 1 and 2 (unit: or ) Et CO2: unit: mmHg or kPa

Menu The menu always occupies the fixed position on the bottom of the screen, user can set the system and perform operation. Frame of menu status Silence on/off: showing the status of silence on Alarm on/off: shows the status of alarm on or off

or off ,

Trend: the function is for operator observing the patients latest 72 hours change, including historical data table, HR, NIBP, SpO2, ST segment. System setup: you can configure various aspects of the monitor, including system time, simulation, print setup, color, display wave, language, color, etc.. Menu bar: it shows the different menus of every operation.

Function buttons


1 Alarm ALARM button, pressing the button will prohibit all the technically audio alarm and physically audio alarm for 3 minutes. The audio alarm function will be restored automatically after 3 minutes or be activated when new alarm occurs. As pressing the

button, the icon in menu status shows have been shut off. NOTE When

which indicates all the audio alarms

mark appears, the system can not give out the audio alarm

prompt. Therefore, the operator should use this function carefully.2Silence SILENCE button, when pressing the button, this mark appears in the menu status, indicating that all kinds of sound including the audio alarm and heart beep have been manually muted until the button has been pressed again, the system will immediately restore the normal status, and the icon shows as

NOTE When pressing SILENCE, the system cannot give out the audio alarm and heart beep; therefore, the operator should be considerate in using the function.3Freeze FREEZE button, pressing the button can freeze the waveform of ECG. The screen displays two traces of ECG waveform. When one trace is active, pressing the FREEZE button will freeze another trace. Pressing FREEZE button again will restore the normal monitor status. 4Start/Cancel


START/CANCEL BP measuring button, pressing the button will inflate the cuff to start a new NIBP measurement. When measuring, press it to cancel the measurement and deflate the cuff, including the CYCLE and STAT (NOT STOP) measuring mode. 5Print PRINT button, pressing this button will motivate the recorder or desktop printer to output the result if the monitor is equipped with them. (6) Menu Main MENU button, pressing the button will exit the submenu and refresh the screen. 7Rotary Knob The operator uses the rotary knob to select the menu item and modify the setup. It can be rotated clockwise or counter-clockwise and pressed like other buttons. The operator uses the knob to realize the operations.

The method of using the knob to execute the operation:

Fig. 1-4

Rotary knob is just like the cursor of computer. When operator rotates the knob on the icon where the operation is wanted, the icon will be automatic highlight. Then pressing the knob, operator will open the setup menu of the corresponding parameter so as to set up the menu.
