Service Manual CNS-9701 iii

In IEC 60601-1-2 Medical Electronic Equipment, Part 1: General Requirements for Safety, 2. Collateral

Standard: Electromagnetic compatibility-Requirements and test. Section 36. 202. 2 Radiated radiofrequency electromagnetic fields, PATIENT COUPLED EQUIPMENT and/or SYSTEMS applicable IMMUNITY test methods are under consideration at SC62A/WG13. The 3 V/m IMMUNITY level may be inappropriate especially when measuring SpO

2

because physiological signals can be much smaller than those induced by a 3 V/m electromagnetic field.

When measuring SpO

2

, various interference may produce false waveforms which look like pulse waveforms. SpO

2

value and pulse rate may be measured from these false waveforms, causing the alarm to function improperly.

When installing the monitor, avoid locations where the monitor may receive strong electromagnetic interference such as radio or TV stations, cellular phone or mobile two-way radios.

Introduction

1. GENERAL

This service manual provides useful information to qualified service personnel to understand, troubleshoot, service, maintain and repair the CNS-9701A/J/K Central

Monitor (referred to as “monitor” in this service manual).

All replaceable parts or units of this monitor and its optional units are clearly listed to help you locate the parts quickly.

The “Maintenance” section in this service manual only describes the maintenance that should be performed by qualified service personnel. The Maintenance section in the operator’s manual describes the maintenance that can be performed by the user.

The information in the operator’s manual is primarily for the user. However, it is important for service personnel to thoroughly read the operator’s manual and service manual before starting to troubleshoot, service, maintain or repair this monitor. This is because service personnel need to understand the operation of the monitor in order to effectively use the information in the service manual.

Service Manual CNS-9701 1.1

1. GENERAL

General Information on Servicing

Note the following information when servicing the monitor.

WARNING

To avoid the possibility of injury to yourself or damage to the monitor, do not install or remove any component while the power is on. When disassembling, make sure that the monitor is turned off and the power cord is disconnected from the monitor and AC outlet.

There is a high voltage circuit on the power unit.

CAUTIONS

Safety

• There is the possibility that the outside surface of the monitor, such as the operation keys, could be contaminated by contagious germs so disinfect and clean the monitor before servicing it. When servicing the monitor, wear rubber gloves to protect yourself from infection.

• There is the possibility that when the lithium battery or LCD unit is broken, a solvent could flow out or a toxic substance inside it could come out. If the solvent or toxic substance contacts the eyes or skin, wash immediately and thoroughly with water and see your physician.

Never rub your eyes, otherwise you may lose your eyesight.

•

To avoid accidental electrostatic discharge which could damage the components of the monitor, use a grounded wrist strap when installing or removing any component of the monitor.

• Use a pair of clean cotton gloves when replacing the LCD unit. If it is damaged, your hand may get injured.

Liquid ingress

The monitor is not waterproof, so do not install the monitor where water or liquid can get into or fall on the monitor. If liquid accidentally gets into the monitor or the monitor accidentally falls into liquid, disassemble the monitor, clean it with clean water and dry it completely. After reassembling, do the patient safety checks and function/performance checks to verify that there is nothing wrong. If there is something wrong with the monitor, contact your Nihon

Kohden representative for repair.

1.2



1. GENERAL

Environmental Safeguards

Depending on the local laws in your community, it may be illegal to dispose of the lithium battery in the regular waste collection. Check with your local officials for proper disposal procedures.

Disinfection and cleaning

To disinfect the outside surface of the monitor, wipe it with a nonabrasive cloth moistened with any of the disinfectants listed below.

Do not use any other disinfectants or ultraviolet rays to disinfect the monitor.

- Chlorohexidine gluconate solution:

- Benzethonium chloride solution:

- Glutaraldehyde solution:

- Benzalkonium chloride:

- Hydrochloric alkyl diaminoethylglycine:

0.5%

0.2%

2.0%

0.2%

0.5%

Transport

• Use the specified shipment container and packing material to transport the monitor. If necessary, double pack the monitor. Also, put the monitor into the shipment container after packing so that the buffer material does not get inside the monitor.

• When transporting a board or unit of the monitor, be sure to put it in a conductive bag. Never use an aluminum bag to transport a board or unit. Also, never use a styrene foam or plastic bag which generates static electricity to wrap the board or unit of the monitor.

Handling the monitor

• Because the outside surface of the monitor is made of resin, the outside surface of the monitor is easily damaged. So when handling the monitor, remove clutter from around the monitor and be careful to not damage the monitor or get it dirty.

• Because most of the boards in the monitor are multilayer boards with surface mount electrical devices (SMD), a special tool is required to remove and solder the electrical devices on it. To avoid damaging other electrical components, do not remove and solder SMD components yourself.

Otherwise, data communication cannot be performed properly and it causes incorrect monitoring. When adding a monitor to an already operating network, set the IP address on the monitor before connecting the monitor to the network.


1. GENERAL

Turning the Power On/Off

WARNING

••••• Do not turn off the display to which the sound cable is connected.

Otherwise there is no alarm sound.

••••• Do not adjust the sound volume at the display unit. If you decrease the display unit volume to the minimum, there is no alarm sound.

••••• When monitoring with two displays, do not turn off either display.

Otherwise some monitored beds cannot be monitored.

CAUTION

••••• Follow the specified procedure to turn off the central monitor.

Otherwise, patient data will be deleted and data in the hard disk and the hard disk itself may be damaged.

••••• After turning the power on, confirm that there is a test sound from the built-in speaker of the display.

Discharge and Receiving

Channel Change WARNING

••••• Check that the channel number of the appropriate transmitter is displayed on the central monitor screen. Otherwise data of a different patient will be monitored or no signal will be received by the central monitor.

••••• Do not use the same channel for different patients. Otherwise two patients’ data will be lost due to mutual modulation interference or another patient’s data may appear on the monitor screen.

CAUTION

••••• When admitting a new patient, first delete all data of the previous patient. Otherwise, the data of the previous patient and new patient will be mixed together and cause misunderstanding of the patient history.

••••• When you change the receiving channel to monitor a new patient, first delete all data of the previous patient. Otherwise, the data of the previous patient and new patient will be mixed together and cause misunderstanding of the patient history.

1.8


Temporary Discharge

1. GENERAL

WARNING

When a temporarily discharged patient comes back, resume monitoring for the patient. During temporary discharge, there is no display of measurement values, alarm function and data saving.

Patient Transfer

CAUTION

••••• Keep the original bedside monitor and the destination bedside monitor power on and connected to the network until the transfer completes. Otherwise transfer fails and the data is lost. After transfer, confirm that the data was correctly transferred to the destination bedside monitor.

••••• When the patient is transferred more than once between different central monitors in the network, the data saved on the original central monitor is deleted.

Alarm


WARNING

••••• When the Alarm Suspend key on the transmitter is pressed, all alarm functions for the patient are suspended.

••••• Even if the alarm is set to ON, there is no arrhythmia alarm when arrhythmia analysis is turned OFF at the bedside monitor and/or central monitor.

••••• Before you start monitoring a new patient, confirm alarm settings.

Alarm settings return to Alarm Master 1 settings when a bed is discharged or a receiving channel is changed.

••••• Securely connect the sound cable. There is no sound if the cable comes off.

CAUTION

••••• When the upper or lower alarm limit is set to OFF, there will be no upper or lower alarm for that limit. When it is set to OFF, frequently observe the patient.

••••• Alarm does not occur for an arrhythmia whose alarm is set to OFF.

There is no indication that the alarm is set to OFF. Be careful when you set the alarm to OFF.

1.9

1. GENERAL

ECG Monitoring

CAUTION

••••• If there is any doubt about the arrhythmia analysis, make the central monitor relearn the patient’s VPC. Otherwise, an important arrhythmia may be overlooked.

••••• The central monitor does not perform ECG analysis. Therefore, the

QRS sound at the central monitor may not synchronize with patient’s actual QRS when complicated arrhythmias occur or during pacing.

••••• The ST level transmitted from a transmitter is not designed to be accurate enough for diagnosis. Do not rely on the ST level displayed on the central monitor.

••••• The QRS sound at the central monitor has a delay of approximately several seconds because of network connection.

••••• When the full disclosure waveform is expanded to actual size, it may be distorted because it has been compressed then expanded. When reading the expanded ECG waveforms, be aware of this distortion.

••••• Turn the pacing detection to ON when monitoring a pacemaker patient. Otherwise QRS and pacemaker spike may not be distinguished and pacemaker failure may not be recognized.

NIBP Measurement

WARNING

••••• When performing long term measurements at intervals less than 2.5 minutes, periodically check the state of the patient, blood vessels and limb for adequate circulation. Congestion may occur at the measurement site.

••••• When performing periodic measurements for a long term, periodically check the circulation condition.

CAUTION

Before you remotely start and stop NIBP measurement from the central monitor, confirm the state of the patient at the bedside monitor.

Carefully start and stop NIBP measurement from the central monitor.

1.10


Maintenance

1. GENERAL

CAUTION

••••• Before maintenance (inspection, cleaning, disinfection), turn the central monitor power off and disconnect the power cord from the

AC outlet. Otherwise the operator may receive electrical shock or the central monitor may malfunction.

••••• Do not disassemble or repair the central monitor. Disassembly and repair must be performed by qualified service personnel.

••••• Software upgrade must only be done by qualified service personnel or a person with technical knowledge. If upgrade is not done correctly, the central monitor may freeze.

••••• Do the regular inspection according to the cycle specified by Nihon

Kohden. Otherwise, deterioration and loss of function are overlooked and it results in incorrect monitoring.

••••• Restart the central monitor once every three months. Otherwise the operation becomes unstable and monitoring may stop. During restarting, patients monitored by the central monitor must be monitored by another instrument.

••••• Replace the hard disk once every two years. If the hard disk gets damaged, monitoring is incorrect and all data saved in the central monitor is lost.

For the VL-971R/RK LCD unit

••••• Follow your hospital regulations to handle blood or bodily fluids on the display.

••••• Be careful not to let any liquid get inside the display.

6. ADJUSTMENT

Adjusting the VL-971R Display Unit

Automatic Adjustment

When a CRT display unit is used with a personal computer, adjustment of the CRT display unit is not required. However, when an LCD display unit is used with a personal computer, adjustment at the LCD display unit is usually required for clear screen display.

Newer LCD display units have automatic screen adjustment which handles the

RGB output signals from most personal computers within an acceptable range. To more clearly display the screen, the LCD display units also have manual screen adjustment. The VL-971R display unit has both automatic and manual screen adjustments.

This display unit accepts the analog RGB signals. The red, green and blue primary color signals are individually input to the display unit. The combination of primary colors makes the different colors as shown below.

According to the above table, you can judge which primary color has something wrong when a color problem occurs.

For example, if the display color which should be white is yellow, the blue color signal has a problem. However, to specify which part, i.e. display unit, main unit or cable between them, has a problem, you have to replace the unit or cable with a known good compatible unit or cable one at a time.

When the screen display is not normal, do the following procedure so that the screen display settings are automatically adjusted. Refer to “LCD Unit VL-971R/

RK” of the “Panel Descriptions” in Section 1.

1.

Check that the RGB signals are input to the display unit.

2.

Press the S (Video Source) button on the rear of the display unit. The adjustment window appears on the screen.

3.

Check that “Computer” is selected in the window and highlighted in yellow.

4.

Press the Down/Left button twice. The screen display settings such as the horizontal and vertical synchronization settings are automatically adjusted.

If the RGB signals are poor or the RGB output signals from the main unit are not appropriate for the display unit, manual adjustment is also required.


6. ADJUSTMENT

Manual Adjustment

After performing the automatic adjustment, perform the following procedure.

1.

Check that the CNS system program is running.

2.

Select “Horizontal Position” from the setting items.

3.

Adjust the horizontal position so that the left edge of the screen meets the left edge of the LCD display area.

4.

Use a magnifying glass and check that there is no position difference between the left edges.

5.

Select “Horizontal Size” from the setting items.

6.

Adjust the horizontal size so that the right edge of the screen meets the right edge of the LCD display area.

7.

Use a magnifying glass and check that there is no position difference between the right edges.

8.

Select “Focus” from the setting items.

9.

Adjust the focus so that the entire screen is most clearly displayed. If the focus setting is not optimal, the screen blurs.

10. Select “Color Temperature Menu” from the setting items and select each primary color in the color temperature menu to adjust the color tone.

NOTE

When the primary color has something wrong, usually it is caused by a failure of the display unit, main unit or cable between them. Solving the problem with the color tone adjustment is rare.

Setting the IP Address on Each Instrument

Each instrument in the network has an IP address for data communication.

Duplicate IP addresses must not be present in the same network.

A unique IP address is assigned to each instrument at shipment. Therefore, there should be no duplicate IP addresses and usually the IP address does not need to be changed.

If the IP address needs to be changed due to the network management in the facility, the IP address can be changed manually.

CAUTION

The network must be managed by the network administrator. Make sure that each monitor in the network has a different IP address.

Otherwise, data communication cannot be performed properly and it causes incorrect monitoring. When adding a monitor to an already operating network, the IP address of the monitor must be set before connecting the monitor to the network.

NOTE

••••• To avoid communication trouble, do not connect the network cable to each instrument before IP address setting is complete.

••••• Contact your Nihon Kohden distributor or representative when changing the IP address manually.

Manually Setting the IP

Address of the Central

8. NETWORK SETTINGS

Selecting the Monitored Beds

One bedside monitor can be monitored on several central monitors, but the data can only be stored on one central monitor. When you register a monitored bed on the Monitor Settings of the System Setup, you will be asked if you want the central monitor to store the bed’s data. Availability of setting and operations depends on whether or not the bed’s data is saved in the central monitor or another central monitor. Refer to the CNS-9701 operator’s manual.

A central monitor can monitor and store data of beds in a different group.

However, it is recommended to monitor and store data of the beds in the same group as the central monitor so that data will not be mixed or lost.

Changing Settings of System Setup, Patient Setting and Setup

Before using the central monitor, confirm that the settings on the System Setup window and the Patient Setting window are correct. Change them if necessary.

If you change the units, date and time when the network is in operation, the change on any instrument affects all instruments in the network.


8. NETWORK SETTINGS

Adding an Instrument to the Network During System Operation

An instrument can be connected to a network which is already running. The network does not need to be turned off. Check the following points.

• The network installation must comply with IEC 60601-1-1 “Safety

Requirements for Medical Electrical Systems”. Refer to the Network and System installation guide and consult with a biomedical engineer or Nihon Kohden distributor.

• The IP address is correctly set on the instrument.

CAUTION

The network must be managed by the network administrator. Make sure that each monitor in the network has a different IP address. Otherwise, data communication cannot be performed properly and it causes incorrect monitoring. When adding a monitor to an already operating network, the IP address of the monitor must be set before connecting the monitor to the network.

• The power of the instrument to be added is turned off before connecting it to the network. When the instrument is properly connected to the network, turn the instrument power on.

• Assign the instrument name (bed name/CNS name) and group name to the instrument .

CAUTION

When the monitor is connected to a central network, set the bed name/

CNS name and group name on the monitor to correctly identify the bed on the central monitor. Otherwise the monitor cannot be managed properly. A new instrument is connected to the network with the factory default bed name/CNS name and group name. Therefore, if you don’t assign a proper name to the instrument after connection, it can cause patients to be mixed up.

• Check that the date and time and unit setting is the same as the other instruments in the network.
