Technical Service Manual
Section 1
INTRODUCTION The LifeCare™ 5000 Series Drug Delivery System is a microprocessor-based, dual-channel infusion system that provides consistent delivery of two different fluids, at two different flow rates, from two containers, through the same cassette and into a common administration line. The LifeCare 5000 provides two methods of delivery: Macro and Micro. Each delivery method allows a choice of non-concurrent or concurrent rate and dose delivery selection (see Table 1-1). Through microprocessor-based firmware, the infusion system features self-prompting for all setup and operating sequences, continual updates of operating and delivery status, nurse-selectable callback for secondary dose, and continual line pressure monitoring and read-out. Infusion system design also accommodates flow detector option on primary, 10 pounds per square inch (psi), 68.9 kPa adjustable occlusion pressure, and syringe or vial delivery capability. The infusion system administers a variety of medical fluids, from 5 percent dextrose injection, USP, to enteral feeding products and blood. Primary and secondary doses of compatible drugs may be delivered concurrently. The DataPort™ 1.6 Series allows continuous infusion system monitoring when connected to a properly configured host computer. For additional information, see the LifeCare 5000 System Operating Manual.

COMPONENT DESIGNATORS Components are indicated by alpha-numeric designators, as follows: Battery
BT
Diode
D
Resistor
R
Capacitor
C
Fuse
F
Switch
SW
Crystal
Y
Integrated Circuit
U
Transistor
Q
The number following the letter is a unique value for each type of component (e.g., R1, R2). 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
1.5
USER QUALIFICATION The LifeCare 5000 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 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 systems. 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 infusion system instead of some other source in the environment, set the infusion system so that it is temporarily not delivering fluid. Disappearance of the abnormality indicates that it was probably caused by electronic noise generated by the infusion system. Proper setup and maintenance of the monitoring equipment should eliminate the artifact. Refer to the appropriate monitoring system documentation for setup and maintenance instructions.
1.7
INFUSION SYSTEM INSTALLATION CAUTION: Infusion system damage may occur unless proper care is exercised during product unpacking and installation. CAUTION: Infusion system performance may be degraded by electromagnetic interference (EMI) from devices such as electrosurgical units, cellular phones, and two-way radios. Operation of the infusion system under such conditions should be avoided. The infusion system installation procedure consists of unpacking, inspection, and self test.
1.7.1
UNPACKING Inspect the shipping container for damage prior to opening. Should any damage be found, contact the delivering carrier immediately. 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 infusion system to the factory. Verify the shipping container contains a copy of the System Operating Manual.

INSPECTION Inspect the infusion system periodically for signs of defects such as worn accessories, broken connections, or damaged cable assemblies. Also inspect the infusion system 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: Do not place the infusion system in service if the battery is not fully
charged. To make certain the battery is fully charged, connect the infusion system to AC (mains) power for 16 hours.
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 conduct the self test, proceed as follows: 1. Connect the AC power cord to a grounded, hospital-grade receptacle and confirm the AC power symbol on the front panel is lit. 2. Lift the door latch. Hold a primed cassette by its finger grip and insert the set into the door guides. Do not force the cassette. It should slide into the guides easily. 3. Close the door latch to lock the cassette in place. 4. If a flow detector is used, confirm that it is securely connected to the accessory jack (labeled ACC) on the back of the infuser. 5. The infusion system automatically initiates a self test to check internal systems. When the self test completes, verify the screen displays match Figure 1-1.
Note: If any malfunction is detected by the self test, an alarm sounds and the screen displays a malfunction code. If the alarm sounds, do not place the infusion system in service. Note the malfunction code and contact Hospira.
6. After the infusion system self test successfully completes, set the delivery mode (see Section 1-10). LIFECARE

OBTAINING THE SOFTWARE VERSION NUMBER To obtain the infusion system software version number, proceed as follows: 1. Connect the infusion system to AC (mains) power. 2. Lift the door latch and insert a primed cassette into the cassette door holder. 3. Close the door latch to lock the cassette in place.
Note: The infusion system automatically initiates a self test when the cassette is in place and the door latch is closed.
4. When the SELF TEST:OK screen appears on the LCD, press the [REVIEW/CHANGE] touchswitch. The screen displays the software version number.
Note: The
SELF TEST:OK screen appears for only three seconds.

SETTING THE DELIVERY MODE The infusion system allows a selection of six delivery modes, as follows: - Macro (single channel) - Macro Secondary (dual channel, single dose) - Macro Multidose (dual channel, multidose) - Micro (single channel) - Micro Secondary (dual channel, single dose) - Micro Multidose (dual channel, multidose) Delivery mode selection is determined by a dual in-line package (DIP) switch located under the DIP switch cover on the back of the infuser. Figure 1-2 illustrates the settings, and Table 1-1 lists the flow parameters for each delivery mode. To reset the delivery mode, proceed as follows: 1. Open the cassette door and remove the cassette. 2. Using a small flat-blade screwdriver, remove the screw from the DIP switch cover. Remove the cover to expose the DIP switches. 3. Set the DIP switch to the appropriate position for the desired delivery mode. 4. Verify the new delivery mode by closing the cassette door with a primed cassette properly installed. 5. Attach the DIP switch cover.
