Safety

Summary

CAUTION

WARNING

The general safety information in this summary is for both operating and servicing personnel. Specific warnings and cautions will be found throughout the Operator’s Guide and other manuals where they apply. Such specific warnings and cautions may not appear here in this summary.

CAUTION statements in the documentation identify conditions or practices that could result in damage to the equipment or other property.

WARNING statements in the documentation identify conditions or practices that could result in personal injury.

Symbols The following symbols may appear in the documentation, and on labels on

the Propaq monitors.

DANGER: Risk of explosion when used in the presence of flammable anesthetics. (This is on older versions only.)

Type CF, Isolated patient connections comply with the allowable risk (leakage) current limits for direct cardiac application and are protected against the effects of defibrillation.

Type BF, Isolated accessible and applied parts comply with the allowable risk (leakage) current limits for noncardiac body applications, protecting the patient and operator from risk of electric shock.

Protected against water dripping vertically. (Protection Classification IPX1 per IEC Publication 529.)

IPX1

DC power input connector for applications not requiring a “high output” power adapter.

DC power input connector for applications requiring a “high output” power adapter.

For continued fire protection, use only the specified fuse.

Internal power transformer meets requirements of a short-circuit-proof safety-isolating power transformer (symbol is located on ac power adapter).

Caution: Refer to User’s Guide and accompanying documentation.

Caution: Refer servicing to qualified service personnel. (For products certified by Underwriters Laboratories.)

Important Safety

Considerations

Place the product in a location where it cannot harm the patient should it fall from a shelf or other mount.

Do not autoclave this product. Inspect the power adapter cord periodically for fraying or other damage, and

replace the adapter as needed. (The power adapter is not a serviceable part; however, the detachable power cord used with the Universal Power Adapter is replaceable). Do not operate the apparatus from mains power with a damaged power adapter cord or plug.

Frequent electrical and visual checks should be made on cables and electrode wires. Broken or frayed electrode wires, or loose snap-fittings may cause interference or loss of signal. Particular attention should be paid to the point at which the wire enters the snap-fittings, since flexure will eventually cause breakage of strands at this point.

Avoid electrosurgery burns at monitoring sites by ensuring proper connection of the electrosurgery return circuit. If the electrosurgery return electrode is improperly connected, the other patient-connected monitoring electrodes and transducers (particularly ECG electrodes and temperature probes) will serve as return paths for the high-frequency energy. This is especially true for older electrosurgery units which have the return circuit deliberately earth-grounded. For improved safety, never deliberately ground the return circuit of an isolated-output electrosurgery unit. If necessary, operate the monitor on battery power only to prevent a return to earth ground through the monitor.

To assure operator safety during defibrillation, keep the discharge paddles away from ECG and other electrodes, as well as other conductive parts in contact with the patient. During defibrillation, always avoid contact with any accessories, such as cables and sensors, connected to the Propaq’s left side panel. For additional safety precautions, refer to the defibrillator operator’s manual.

To ensure patient safety, the conductive parts of the ECG electrodes (including associated connectors) and other patient-applied parts should not contact other conductive parts, including earth ground, at any time.

Do not operate this product in the presence of flammable anesthetics. Explosion can result. This product must only be operated in strict conformance with local fire prevention regulations.

ii 810-0334-01 Calibration/Maintenance Manual

Propaq 100-Series Monitors Safety Summary

NOTE

Within certain governmental jurisdictions, all interconnected accessory equipment must be labeled by an approved testing laboratory. After interconnection with accessory equipment, risk (leakage) current and grounding requirements m ust be maintained.

To ensure patient safety, use only accessories recommended or supplied by Protocol Systems, Inc. For a list of those accessories, see the Protocol Products and Accessories book (PN 810-0409-00) that accompanies the Users Guide.

Do not autoclave accessories unless the manufacturer’s instructions clearly approve it. Many accessories can be severely damaged by autoclaving.

To ensure conformance to risk (leakage) current requirements when operating from an ac mains power source, use only a Protocol Systems’ 503-0002, 503-0053, or 503-0054 power adapter.

Pour limiter le courant de fuite conformément aux exigences lorsque l’appareil est branché au secteur, utiliser seulement un bloc d’alimentation de la série 503-0002 503-0053, 503-0054.

A product that has been dropped or severely abused should be checked by qualified service personnel to verify proper operation and acceptable risk (leakage) current values.

While under warranty, the Propaq should be serviced only by Protocol Systems’ service personnel. Service documentation is available from Protocol Systems, Inc. to aid the biomedical engineer during post-warranty period service.

Component replacement and internal adjustments must be made by qualified service personnel only.

Service

The Calibration/Maintenance Manual provides instructions and information for technicians to repair the Propaq at the replaceable module level. Replaceable modules include circuit boards, large hardware items, such as the air pump, check valve, chassis parts, and other parts easily replaced without desoldering of surface-mount components and other small hardware. Module-level repair allows monitor repair in minimal time and for a nominal price for the replaceable module.

Because of the specialized equipment and knowledge required to manufacture and repair the Propaq, Protocol Systems, Inc. recommends that only Protocol’s authorized repair facilities provide component-level repair. If repair by other than Protocol’s authorized repair facilities is required, such a facility must have the necessary equipment to service and repair surface mount technology (SMT) electronics as well as the specialized equipment to service Propaq monitors. The Schematics & Drawings Set (orderable as 810-0334-10) and appropriate option section (SpO PN 810-0334-30, or CO

PN 810-0334-40) provides schematics, parts lists,

PN 810-0334-20, Printer

etc. helpful in component-level servicing. Contact Protocol Systems, Inc. for more information.

Service Intervals Table 2-1 lists recommended service intervals and procedures that should be

considered in order to keep the monitor in good operating condition.

Functional

V erification

The functional verification procedures verify proper operation of the monitor, oximeter, and printer. This procedure should be performed at intervals or conditions listed in Table 2-1.

Self Test Many functions, such as alarms, waveform and scale sizing, and printer

control, are software operations. Since system software is automatically checked during the monitor’s power-up self-test, all software functions work normally if no error messages appear during the power-up sequence. (Some error messages indicate hardware failures.)

The Service Menus Service Menus are provided to facilitate functional verification. The Service

Menus (Figure 2-1) contain several functions for testing and verifying the Cuff channel, display, invasive pressure channel (models 104 and 106 only), and printer. During the functional verification procedure, the Service Menu functions will be accessed to perform necessary tests.

Procedure NOTE

If the monitor has been stored for longer than one month without the monitor connected to the ac adapter (for recharging), the battery voltage should be checked. The battery may need to be replaced if it cannot hold a charge.

The functional verification must be done only when the monitor is fully assembled. Equipment required to perform this procedure is shown in Table 2-2. Most items not commercially available can be made according to the information in Appendix A.

2-6 810-0334-01 Calibration/Maintenance Manual

Propaq 100-Series Monitors Section 2—Installation and Service

NOTE

If you plan to use a Dynatech/Nevada model 213A, 215A, or 217A Patient Simulator to simultaneously simulate ECG and invasive blood pressure, see Appendix B for important information.

If the monitor did not pass the functional verification, or when it is time to do a routine calibration, see the Calibration Procedure in Section 3.

Functional verification and safety checks must always be done after monitor disassembly or calibration, or whenever there is a question about the safety of the patient functions.

NOTE

Before starting the verification procedures, charge the battery for at least 8 hours with the monitor turned off. (Charge for 12 hours if a Printer or SpO

module is attached.)

Power System The following steps check the integrity of the power system.

1. If the ac power adapter is not plugged in, plug it into an ac socket with the correct voltage and connect it to the monitor’s right side panel dc power connector.

2. Check that the green

BATTERY CHARGING indicator lights.

3. Disconnect the power adapter from the monitor. Check that the

BATTERY CHARGING indicator turns off.

CAUTION

In the next steps, carefully check for the proper polarity of the connection between the power supply and the monitor. If voltage is applied with the wrong polarity, it will blow an internal fuse (F1 on the Recharger board). Refer to the diagram on the monitor’s right side panel for proper polarity.

4. Turn on the dc power supply and set it for 15 V

5. Using the power supply adapter cable (constructed as shown in Appendix A), connect the power supply to the monitor’s dc input connector on the right side panel.

6. Check that the

BATTERY CHARGING LED indicator lights.

7. Check that the current draw from the supply is less than 650 mA.

NOTE

Initial charge current can be as high as 880 mA. However, as the battery charges, the current will decrease. A fully charged battery draws less than 100 mA. You should notice the current draw slowly drop the longer the dc supply is connected to the monitor.
