Technical Service Manual

Section 1

INTRODUCTION The LifeCare™ PCA3 Infusion System is a patient-controlled analgesia management system designed to meet the fluid delivery requirements of today’s evolving healthcare environments. The system is comprised of a pole mounted or tabletop drug infuser, drug vials with a variety of pre-filled drugs and drug concentrations, and an administration set. The LifeCare PCA3 is a self-contained, microprocessor-based infusion device with keypad controls, an LED display, integral locking system, pole clamp, barcode reader for drug identification, field-upgradeable software, and a connector for a DataPort that includes inputs and outputs for devices such as a computer or printer. The infuser is intended to operate on AC power. An internal battery is provided to maintain operation for short periods of time during patient transport and when AC power is lost or not available.

1.1

SCOPE This manual is organized into 11 sections: ❏ Section 1 Introduction ❏ Section 2 Warranty ❏ Section 3 System Operating Manual ❏ Section 4 Theory of Operation ❏ Section 5 Maintenance and Service Tests ❏ Section 6 Troubleshooting ❏ Section 7 Replaceable Parts and Repairs ❏ Section 8 Specifications ❏ Section 9 Drawings ❏ Index ❏ Technical Service Bulletins If a problem in device operation cannot be resolved using the information in this manual, contact Hospira (see Section 6.1). Specific instructions for operating the device are contained in the LifeCare PCA3 System Operating Manual. The terms “infusion system”, “infuser”, and “device” are used interchangeably throughout the manual. Figures are rendered as graphic representations to approximate actual product. Therefore, figures may not exactly reflect the product. Screen representations are examples only, and do not necessarily reflect the most current configuration.

Warnings and Cautions

CAUTION: Use proper ESD grounding techniques when handling components.

Throughout this manual, warnings, cautions, and notes are used to emphasize important information, as follows: WARNING:

A WARNING CONTAINS SPECIAL SAFETY EMPHASIS AND MUST BE OBSERVED AT ALL TIMES. FAILURE TO OBSERVE A WARNING MAY RESULT IN PATIENT INJURY AND BE LIFE-THREATENING.

CAUTION: A CAUTION usually appears in front of a procedure or statement and contains information that could prevent hardware failure, irreversible damage to equipment, or loss of data.

 Note: A note highlights information that helps explain a concept or procedure. 1.3

COMPONENT DESIGNATORS Components are indicated by alpha-numeric designators, as follows: Battery

Diode

Resistor

Capacitor

Fuse

Switch

Crystal

Integrated Circuit

Transistor

The number following the letter is a unique value for each type of component (e.g., R1, R2).

 Note: Alpha-numeric designators may be followed with a dash (-) number that indicates a pin number for that component. For example, U15-13 is pin 13 of the encoder chip [U15] on the interface PWA.

USER QUALIFICATION The infusion system is intended for use at the direction or under the supervision of licensed physicians or certified healthcare professionals who are trained in the use of the infusion system and the administration of parenteral and enteral fluids and drugs, and whole blood or red blood cell components. Training should emphasize preventing related IV complications, including appropriate precautions to prevent accidental infusion of air. The epidural route can be used to provide anesthesia or analgesia.

1.6

ARTIFACTS Nonhazardous, low-level electrical potentials are commonly observed when fluids are administered using infusion devices. These potentials are well within accepted safety standards, but may create artifacts on voltage-sensing equipment such as ECG, EMG, and EEG machines. These artifacts vary at a rate that is associated with the infusion rate. If the monitoring machine is not operating correctly or has loose or defective connections to its sensing electrodes, these artifacts may be accentuated so as to simulate actual physiological signals. To determine if the abnormality in the monitoring equipment is caused by the infuser instead of some other source in the environment, set the device so that it is temporarily not delivering fluid. Disappearance of the abnormality indicates that it was probably caused by electronic noise generated by the infuser. Proper setup and maintenance of the monitoring equipment should eliminate the artifact. Refer to the appropriate monitoring system documentation for setup and maintenance instructions.

INFUSION SYSTEM INSTALLATION

1.7

INFUSION SYSTEM INSTALLATION CAUTION: Infusion system damage may occur unless proper care is exercised during product unpacking and installation. Accessory equipment connected to the analog and digital interfaces must be certified according to the respective IEC standards (i.e., IEC 60601-1 for medical equipment). Furthermore, all configurations shall comply with the system standard IEC 60601-1-2. Any person who connects additional equipment to the signal input or output part is configuring a medical system, and is therefore responsible for assuring that the system complies with the requirements of IEC 60601-1-2. If in doubt, contact Hospira.

1.7.1

UNPACKING Inspect the shipping container as detailed in Section 1.7.2. Use care when unpacking the infusion system. Retain the packing slip and save all packing material in the event it is necessary to return the infuser to the factory. Verify the shipping container contains a copy of the PCA3 System Operating Manual.

1.7.2

INSPECTION Inspect the shipping container for damage. Should any damage be found, contact the delivering carrier immediately. CAUTION: Do not use the device if it appears to be damaged. Should damage be found, contact Hospira (see Section 6.1). Inspect the infusion system periodically for signs of defects such as worn accessories, broken connections, or damaged cable assemblies. Also inspect the infuser after repair or during cleaning. Replace any damaged or defective external parts.

1.7.3

SELF TEST CAUTION:

Do not place the infusion system in service if the self test fails.

 Note: When plugging the device into an AC power outlet, grasp the AC power

cord plug and use a forward motion into the socket. Do not use a sideways motion. When unplugging the device, grasp the AC power cord plug and pull straight out. Do not pull out using the power cord cable and do not pull out at an angle.

To perform the self test, see Figure 1-1 and proceed as follows: 1. Unlock and open the security door. 2. Connect the AC power cord to a grounded, hospital grade, 120 VAC, 50-60 Hz outlet and confirm the AC power indicator is lit.

 Note: If the quality of earth grounding source is in doubt, use battery power.

SECTION 1 INTRODUCTION

 Note: When the AC plug indicator is off and the battery indicator on the display is flashing, the infusion system is operating on low battery power and should be recharged.

3. Press [ON/OFF] to turn on the power. The infuser performs a self test verifying the integrity of the software, memory, and selected electronic functions. 4. Verify the time and date. To set the time and date, see Section 1.7.4. 5. To assure the battery is fully charged before placing the infuser in service, connect the AC power cord to a grounded AC outlet for a minimum of 24 hours. If an alarm condition occurs during the self test, press [ON/OFF] twice then repeat the self test. If the alarm condition recurs, note the message and take corrective action (see Section 6). Repeat the self test. If the alarm condition recurs, remove the infusion system from service and contact Hospira.
