Warranty

Philips Medical Systems makes no warranty of any kind with regard to this material, including, but not limited to, the implied warranties or merchantability and fitness for a particular purpose.

Philips Medical Systems shall not be liable for errors contained herein or for incidental or consequential damages in connection with the furnishing, performance, or use of this material.

WARNING

As with electronic equipment, Radio Frequency (RF) interference between the cardiograph and any existing RF transmitting or receiving equipment at the installation site, including electrosurgical equipment, should be evaluated carefully and any limitations noted before the equipment is placed in service.

Radio frequency generation from electrosurgical equipment and close proximity transmitters may seriously degrade performance.

WARNING

Like all electronic devices, this cardiograph is susceptible to electrostatic discharge (ESD). Electrostatic discharge typically occurs when electrostatic energy is transferred to the patient, the electrodes, or the cardiograph. ESD may result in ECG artifact that may appear as narrow spikes on the cardiograph display or on the printed report. When ESD occurs, the cardiograph ECG interpretation may be inconsistent with the physician interpretation.

Philips Medical Systems assumes no liability for failures resulting from RF interference between Philips Medical Systems medical electronics and any radio frequency generating equipment at levels exceeding those established by applicable standards.

CAUTION

The use of parts or accessories other than those approved by Philips Medical Systems may compromise product performance.

United States federal law restricts this device to use by or on the order of a physician.

THIS PRODUCT IS NOT INTENDED FOR HOME USE.

Medical Device Directive

Introduction Important Patient and Safety Information

Important Patient and Safety Information

The PageWriter Trim cardiograph isolates all connections to the patient from electrical ground and all other conductive circuits in the cardiograph. This reduces the possibility of hazardous currents passing from the cardiograph through the patient’s heart to ground .

WARNING Failure to follow these warnings could affect both patient and operator safety.

 When operating the cardiograph on AC power, ensure that the cardiograph and all other

electrical equipment connected to or near the patient are effectively grounded.

 Use only grounded power cords (three-wire power cords with grounded plugs) and

grounded electrical outlets. Never adapt a grounded plug to fit an ungrounded outlet by removing the ground prong or ground clip. If an ungrounded plug adapter is requ ired , use a ground strap to connect the equipotential port (rear of the cardiograph) to the power source ground. Use the equipotential port when redundant earth ground is necessary according to IEC 60601-1.

 If a safe ground connection is not ensured, operate the cardiograph on battery power only.  The use of equipment that applies high frequency voltages to the patient (including

electrosurgical equipment and some respiration transducers) is not supported and may produce undesired results.

WARNING Do not touch accessible connector pins and the patient simultaneously.

Electrical shock hazard. Keep cardiograph, Patient Interface Module (PIM) and all cardiograph accessories away from liquids. Do not immerse cardiograph, PIM, or other accessories in any liquids.

 Periodically inspect the patient data cable, lead wires, and AC power cord for any worn or

cracked insulation.

 Keep the patient data cable away from power cords and any other electrical equipment.

Failure to do so can result in AC power line frequency interference on the ECG trace.

 The Philips Medical Systems patient data cable (supplied with the cardiograph) is an

integral part of the cardiograph safety features. Use of any other patient data cable may compromise defibrillation protection and degrade cardiograph performance.

 Only qualified personnel may service the cardiograph or may open the cardiograph

housing to access internal cardiograph components. Do not open any covers on the cardiograph. All internal components must be serviced by qualified personnel.

 Do not use this cardiograph near flammable anesthetics. It is not intended for use in

explosive environments or in operating rooms.

 The use of the analog ECG output signal port (not supported on cardiograph) should not

be used when critical synchronization timing is required.

PageWriter Trim Cardiograph Service Manual 1-3

Page 12

Introduction Important Patient and Safety Information

 Do not touch the patient, patient data cable, or cardiograph during defibrillation. Death or

injury may occur from the electrical shock delivered by the defibrillator.

 Ensure that the electrodes or lead wires do not come in contact with any other conductive

materials (including earth-grounded materials) especially when connecting or disconnecting electrodes to or from a patient.

 Connecting multiple cardiographs to the same patient may pose a safety hazard due to the

summation of leakage currents. Any combination of instruments should be evaluated by local safety personnel before being put into service.

 Do not pull on the paper while an ECG report is being printed. This can cause distortion of

the waveform and can lead to potential misdiagnosis.

 Do not connect any equipment to the cardiograph RS-232 port that does not meet medical

safety requirements and that has not been evaluated by local safety personnel.

 Equipment connected to the cardiograph RS-232 port can cause ground leakage currents

exceeding the maximum specified in IEC 60601-1 safety standards.

 Do not connect any equipment to the cardiograph RS-232 port if a patient is connected to

the cardiograph.

 Only use the Philips Medical Systems AC power cord supplied with the cardiograph.

Periodically inspect the AC power cord and AC power connector to ensure that both are in a safe and operable condition. If the AC power cord or AC power connector is not in a safe or operable condition, operate the cardiograph on battery power and contact Philips Medical Systems for service.

 The cardiograph has been safety tested with the recommended accessories, peripherals,

and leads, and no hazard was found when the cardiograph is operated with cardiac pacemakers or other stimulators.

 Do not connect any equipment or accessories to the cardiograph that are not approved by

Philips Medical Systems or that are not IEC 60601-1 approved. The operation or use of non-approved equipment or accessories with the cardiograph is not tested or supported, and cardiograph operation and safety are not guaranteed.

WARNING When using additional peripheral equipment powered from an electrical source

other than the cardiograph, the combination is considered to be a medical system. It is the responsibility of the operator to comply with IEC 60601-1-1 and test the medical system according to the requirements. For additional information contact Philips Medical Systems.

Do not use non-medical peripherals within 6 feet of a patient unless the non-medical peripherals receive power from the cardiograph or from an isolation transformer that meets medical safety standards.

 Only install Philips Medical Systems software on the cardiograph. The installation or use

of software not approved by Philips Medical Systems is strictly prohibited and cardiograph safety and performance are not guaranteed.

1-4 PageWriter Trim Cardiograph Service Manual

Page 13

Introduction Features and Capabilities

 Only use Philips Medical Systems replacement parts and supplies with the cardiograph.

The use of non-approved replacement parts and supplies with the cardiograph is strictly prohibited. Cardiograph safety and performance are not guaranteed when non-approved replacement parts and supplies are used with the cardiograph.

 Manual measurements of ECG intervals and magnitudes should be performed on printed

ECG reports only. Do not make manual measurements of ECG intervals and magnitudes on the touch screen display since these ECG representations are scaled.

 Only use patient electrodes that are approved by Philips Medical Systems. The use of non-

approved patient electrodes may degrade cardiograph perfo rmance.

 The Philips Medical Systems warranty is applicable only if you use Philips Medical

Systems approved accessories and replacement parts.

Theory of Operation Hardware Logical View

Hardware Logical View

Control of the PageWriter Trim is provided by application software running on the main control board, interacting with numerous hardware and software subsystems. The following are high-level descriptions of these various subsystems.

Main Control Board

The main control SBC contains loader software and the Windows CE kernel image in its internal flash memory (32 MB for PageWriter Trim II/III/Rx, 16MB for PageWriter Trim I). At system boot, a system RAM test is performed by the loader (onboard RAM is 64MB), and then the Windows CE kernel loads. When Win CE loads, the application launcher runs, verifying system and executable images before loading the Ruby application. For PageWriter Trim II/III/Rx, all interaction with the operator is through the Ruby300_APP application. For PageWriter Trim I, all interaction with the operator is through the Ruby100_APP application. The application software is stored in internal Flash memory. For PageWriter Trim II/III/Rx, ECG archives are stored on a separate 128MB CompactFlash (CF) card installed in the main control board.

The following shows devices and interfaces provided by the main control board.

The barcode reader can be configured using special barcodes.

NOTE The PS/2 port is not a plug-and-play port. You must attach the barcode reader to the port before

powering on the unit.

Smart Card Reader

A smart card reader is available as an option. It connects through an external USB connector and provides standard smart card reading capability. PageWriter Trim cardiograph uses the smart card reader to get patient information.

PCMCIA LAN Card

A PCMCIA LAN Card is available as an option. It connects through the PCMCIA slot and provides standard LAN capability. The PageWriter Trim cardiograph communicates with the TraceMaster ECG Management System through the PCMCIA LAN Card.

PCMCIA Modem Card

A PCMCIA modem card is available as an option. It connects through the PCMCIA slot and provides standard modem capability. PageWriter Trim faxes ECG data to remote receivers or communicates with TraceMaster ECG Management System through the PCMCIA modem card.

High Level ECG Data Flow and Storage

General ECG flow begins with acquisition by the Patient Interface Module (PIM) from electrodes placed on a patient. Data is streamed real-time to the main control board, where it is received into the application buffers in RAM. These buffers are used to present the signal data on the real-time screen. When the user initiates an auto report print, corresponding 10-second segments of the signal data are then copied to the temporary ECG storage memory in RAM.

2-4 PageWriter Trim Cardiograph Service Manual

Page 31

High Level ECG Data Flow and Storage Theory of Operation

These 10-second segments are named ECG reports that can be previewed and printed. In the case of Auto mode, the ECG report is automatically printed. An ECG report contains signal data, analysis information, patient demographics, and acquisition information, along with operator and device information. See the PageWriter Trim XML documentation for a complete description of the contents of the ECG data record.

If automatic save after print is set, the ECG report is saved in XML format to the internal main archive. This archive is non-volatile and resides on the internal CompactFlash (CF) card. Index files with a CDB extension are also maintained in this archive.

From the internal main archive, the ECG XML data format files can be copied, deleted, previewed, printed, and transferred to other devices. The internal main archive cannot receive ECG XML files from external devices. Retrieved ECG file storage is limited to the internal remote archive.

NOTE PageWriter Trim-generated ECG XML files comply with the Philips Medical Systems ECG XML

Schema version. They incorporate an embedded CRC32 value, which is used to ensure the data integrity of the file.

Theory of Operation High Level ECG Data Flow and Storage

Internal Main Archive

The internal main archive resides on the internal CompactFlash (CF) card, and is used as the primary ECG data repository. ECG XML files and related index files are stored here in the RubyArchiveInternal directory. All stored ECG files transition through this archive prior to transfer or copying to other devices, such as the PC card.

Currently, the internal main archive is limited to storing the following maximum number of ECGs.

Table 2-1 Maximum Number of ECGs Stored (Internal Main Archive)

Internal Remote Archive

The internal remote archive resides on the internal CompactFlash (CF) card much like the internal main archive. All XML files retrieved from remote sites, such as the TraceMaster ECG Management system, reside in this archive until deleted. ECG XML files and related index files are stored in the RubyArchiveRemote directory.

Currently, the internal remote archive is limited to a maximum of 100 ECGs.

External PC Card Archives

The external PC card archives reside on a compatible PC card inserted into the PC card slot. Files may then be transferred to inserted cards using the Archive mode features of the PageWriter Trim, and are stored as an XML format. An index file is created and maintained on each PC card when CDB files are transferred or copied from the card. Currently, an external PC card archive is limited to storing the following maximum number of ECGs.

Rendered ECG Report Prints

A rendered ECG report print is a representation of the ECG data. This includes a highresolution print of the signal data, and may include configured patient demographics, acquisition information, and other non-signal data elements.

The PageWriter Trim allows the user to customize the fields on an ECG report print. The report print may consist of one or more continuous pages on perforated thermal media from the printer.

Figure 2-3 Rendered ECG Report Print Sample

Fax-Rendered ECG Report Print

A fax-rendered ECG report print is equivalent to the rendered ECG report print, as described in the previous section, except it has been adjusted to comply with fax transmission and resolution device requirements. When the user starts a fax transfer, the ECG report is rendered and transmitted to a remote fax site pre-configured into the unit, using the optional fax and modem PC card. The fax-rendered ECG report print may be stored on the received system end as an electronic file, and not actually used to produce a printed copy.

Theory of Operation Power System Overview

Power System Overview

The PageWriter Trim power system consists of:

 A 65-watt AC/DC medical grade power module  One 12 volt, 2.9 amp-hour lead-acid rechargeable battery  A power supply board which includes battery charging circuitry, various voltage

regulators, and logic circuitry to provide for battery operation

The PageWriter Trim is designed to run primarily on battery power, using the AC power for recharging. The power board has a battery charging chip to control the battery charging. The main board has an A/D converter to monitor voltage of every power supply and a Board Status Register (BSR) to monitor the battery charging status.

The major power draws within the PageWriter Trim are the LCD display backlights, which can draw up to 4 watts, and the thermal printer, which can draw about 48 watts. Provisions have been incorporated into the PageWriter Trim to allow the user to modify the display brightness. To extend battery life, set the display brightness to low or medium level. Also, activate the power save mode (dims the screen) to further extend battery life. The printer control board is current limited for normal printing. However, if print demand is too high, the current limiter will not print the output, resulting in a faded page.

Battery

The 12V recharged sealed lead-acid battery provides the power to the PageWriter Trim. The battery provides a high-current discharge as needed for thermal printing. Built-in protection circuitry in each pack prevents damage to the battery by overcharging, over discharging, over current, and over temperature.

Page 43

Cardiograph Care and Maintenance Battery Maintenance and Care

The sealed lead-acid battery used in the PageWriter Trim family of cardiographs will provide optimum life when the unit is continuously connected to AC power and fully charged after each use. A depleted battery requires 16 hours of continuous charge time to fully charge. Because it is not always possible to allow a full charge cycle between uses, the cardiograph was designed to charge a depleted battery to 90% of its capacity in approximately eight hours.

CAUTION Repeated undercharging of the battery will damage the battery and reduce battery life.

NOTE Philips recommends that the cardiograph be plugged into AC power whenever possible to maximize

battery life.

Battery life varies depending on frequency of use and maintenance. For improved battery life, keep the cardiograph plugged in when not in use. If the battery has been fully charged and requires recharging after a few ECGs, consider replacing it.

For optimal battery performance:

 Only use Philips Medical Systems lead-acid battery (Philips part number 989803130151

with the cardiograph.

 Keep the cardiograph plugged in when not in use.  If the battery has been fully charged and requires recharging after a few ECGs, consider

replacing it.

 The use of cardiograph accessories (bar code reader, magnetic card reader, PC card,

modem) will deplete battery power at a faster rate. The battery will require more frequent charging if these accessories are used with the cardiograph.

NOTE The battery should be removed from the unit and placed in storage if the cardiograph will not be used

for more than one month.

Storing the Battery

Remove the battery from the cardiograph if it will be stored for more than 30 days without use. While in storage, the battery will require a full recharge every 6 months. Charge the battery for at least 16 hours. This will ensure that the battery does not completely discharge while in storage. The battery life will be prolonged when stored in cooler temperatures, but will be damaged if stored below freezing (0

C (104o F) or lower.

To store the battery:

Performance Verification Tests . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5-4

Required Testing Levels

The Performance Verification Tests verify proper operation of the PageWriter Trim following a service event. The level of testing required corresponds to the type of service performed.

NOTE Installation and Preventive Maintenance are not considered service events since the cardiograph is

designed to be installed and maintained by the user. Service Events are divided into two categories: repairs and upgrades. Repairs are then further divided into external repairs and internal repairs.

External Repairs

External repairs consist of the repair or replacement of one or more items when the repair or replacement does not require you to open the cardiograph case. Therefore, only a limited number of tests are necessary to verify performance after a repair. External repairs that involve the PIM and PIM lead set require an ECG simulation test to verify proper ECG signal path.

The typical external repairs include:

 PIM  Patient Leads  Labels  Battery

Refer to Table 5-1 for the required test blocks that must be performed after any external repair occurs.

Internal Repairs

Philips does not support internal repairs performed by users. Only authorized Philips personnel can perform internal repairs.

If the case was opened, regardless of the repair, you must perform additional Performance Verification Tests. Refer to Table 5-1 for the required test blocks that must be performed after any internal repair.

Upgrades

Most PageWriter Trim upgrades are installed by the user, and are not considered service events. The only exceptions are upgrades for the software and the Magnetic Card Reader. Refer to Table 5-1 for the required test blocks that must performed after these upgrades.

The following self-tests are automatically performed during reboot:

 RAM  Software CRC Test  Flash Memory: onboard CompactFlash (CF)  PIM Status  Battery Voltage Test  Printer Status

ECG Simulation (ECG)

Taking an ECG using a 12-lead ECG simulator allows you to verify areas of operation th at the extended self-test cannot check:

 Integrity of the patient leads  Accuracy of the paper speed (not available on all simulators)  Accuracy of the gain settings (not available on all simulators)

Trace differences may result from difference in simulators, simulators settings, and from differences in configuration and control settings on the cardiograph.

To perform the ECG Simulation Test

Connect the PIM lead wires to the simulator.

2 Verify that all lead wires are connected by observing the display for:

– Flat lines or leads off information (for Trim II/III/Rx) – Leads off indicator (for Trim I)

3 Firmly pull each lead wire tight, and then look for excessive noise on the display (may be

indicated by yellow or orange waveforms).

4 Select Auto to start an AUTO 12-Lead recording.

Depending on the cardiograph’s configuration, the ECG may be printed automatically at this point, or it may only be previewed on the display.

5-6 PageWriter Trim Cardiograph Service Manual

Page 69

Performance Verification and Safety Tests Performance Verification Tests

5 If the ECG is not printed automatically, select Enter to start printing.

Verify the following when printing is complete: – Trace activity for all 12 leads. Confirms integrity for all patient electrodes and

leadwires. Noise should measure less than one (1) mm, with no baseline wander. – No gross distortion of complexes or calibration pulses (no overshoot and so forth). – Duration for calibration pulses for correct paper speed. W ith cardiograph set to record

at 25 mm/sec, the calibration pulse should measure 5mm (calibration pulse duration is

200 ms). – Calibration pulse amplitude is correct.

NOTES  An arrhythmia simulator is not an acceptable tool for verifying computerized ECG analysis. The

analysis software is biased to process human ECG data.

 Noise may be an artifact of poor connections to the simulator or position of the cables. If noise

appears, check the connectors or adjust the cable drape.

Safety Tests

This section explains tests of the cardiograph’s electrical safety.

 Use the procedures called out by the manufacturer of the safety analyzer in use.  Test both Normal and Reverse polarity line connections for each test, and record the

worst-case value.

 If a ground reference point is needed for the testing, use the metal grounding stud on the

back of the cardiograph.

Electromagnetic Compatibility (EMC)

Electromagnetic compatibility with surrounding devices should be assessed when using the PageWriter Trim cardiograph.

An electronic device can either generate or receive electromagnetic interference. Testing for electromagnetic compatibility (EMC) has been performed on the PageWriter Trim cardiograph according to the international standard for EMC for medical devices (IEC 606011-2). This IEC standard has been adopted in Europe as the European Norm (EN 60601-1-2).

The PageWriter Trim cardiograph should not be used adjacent to, or stacked on top of other equipment. If the PageWriter Trim cardiograph must be used adjacent to or stacked on top of

PageWriter Trim Cardiograph Service Manual A-5

Page 84

Specifications Electromagnetic Compatibility (EMC)

other equipment, verify that the cardiograph operates in an acceptable manner in the configuration in which it will be used.

The cardiograph will not malfunction when used with electrosurgical equipment. Fixed, portable, and mobile radio frequency communications equipment can affect the

performance of medical equipment. See Table A-4 on page A-9.

Reducing Electromagnetic Interference

The PageWriter Trim cardiograph and accessories may become sensitive to interference from other RF energy sources including power lines. RF energy sources include other medical devices, wireless devices, information technology equipment, and radio/television transmission. Should interference be encountered, as demonstrated by artifact on the ECG trace, attempt to locate the source by assessing:

 if the interference is intermittent or constant?  does the interference occur only in certain locations?  does the interference occur only when in close proximity to certain medical devices?  does the ECG signal quality change dramatically when the AC power cord is unplugged?

Once the source of the interference is located, attempt to attenuate the EMC coupling path by distancing the cardiograph from the source of the interference as much as possible. If further assistance is needed, contact the Philips Response Center nearest you.
