1.4

USER QUALIFICATION The infuser 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 infuser and the administration of parenteral fluids or drugs. Training should emphasize preventing related IV complications, including appropriate precautions to prevent accidental infusion of air.

1.5

ARTIFACTS Non-hazardous, 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 the 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.

ELECTROMAGNETIC COMPATIBILITY

1.6

ELECTROMAGNETIC COMPATIBILITY The Hospira GemStar is compliant with IEC/EN 60601-1-2 (2001), and has been tested and found to comply with electromagnetic compatibility (EMC) limits for the Medical Device Directive 93/42/EEC (EN 55011 Class B and EN 60601-1-2:2001). These limits are designed to provide reasonable protection against harmful interference in a typical medical installation (see the System Operating Manual). CAUTION: Portable and mobile RF communications equipment, such as cellular telephones, two-way radios, Bluetooth® devices, and microwave ovens in close proximity to the infuser may affect or degrade performance of the device. Operation of the infuser under such conditions should be avoided. There is a shared responsibility between manufacturers, customers, and users to assure that medical equipment and systems are designed and operated as intended. Medical electrical equipment requires special precautions regarding electromagnetic compatibility. The electromagnetic environment should be managed to permit the infuser to perform as intended without disturbing other equipment. The infuser should not be used adjacent to or stacked with other equipment. If the device must be used adjacent to or stacked with other equipment, monitor the equipment to assure there is no electromagnetic interference, and verify normal infuser operation.

1.7

INSTRUMENT INSTALLATION CAUTION: Infuser damage may occur unless proper care is exercised during unpacking and installation. Instrument installation consists of unpacking, inspection, and self test.

1.7.1

UNPACKING Inspect the shipping container as detailed in Section 1.7.2. Use care when unpacking the infuser. 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 System Operating Manual.

1.7.2

INSPECTION Inspect the shipping container for damage. Should any damage be found, contact the delivering carrier immediately. CAUTION: Inspect the infuser for evidence of damage. Do not use the device if it appears to be damaged. Should damage be found, contact Hospira. Inspect the infuser periodically for signs of defects. Also inspect the infuser after repair or during cleaning. Replace any damaged or defective external parts.

SECTION 1 INTRODUCTION

1.7.3

SELF TEST CAUTION:

Do not place the infuser in service if the self test fails.

At power-on, the infuser immediately enters an initialization mode and performs the following self tests: - RAM test

- Power loss completion test

- ROM checksum calculation

- CRC verifications on all RAM areas protected by CRCs

- Motor control test - Stuck key test - PIC watchdog test - CONFIG register test

- CRC on calibration data stored in the EEPROM - Calibration data verification

- Battery voltage test The initialization mode completes in approximately 30 seconds. During this time the infuser displays a message that the self tests are being performed. If any test fails, the infuser alarms.

 Note: The device does not infuse during the initialization mode. After successful completion of the initialization mode, if there is not a current program in the infuser, the device enters programming mode so the user can enter a new program. If a program is already in the infuser, the user may choose between the following options: - Use the current program. The infuser enters stop mode after the program is reviewed. - Enter a new program. The infuser enters programming mode, then enters stop mode after the program is reviewed.

 Note: If the infuser has been powered off for less than five minutes, a program review is not required.

OVERVIEW The following sections describe therapy options, differences between therapies, safety features, power sources, and basic operation of the infuser. See Figure 1-1 for an illustration of the infuser.

THERAPIES The Hospira GemStar offers the following types of therapy: - Pain Management

- Continuous

- Total Parenteral Nutrition (TPN)

- mL/hr Only

- Intermittent

- Variable Time

- Weight Dosed The availability of these programs may vary, depending upon the configuration of the infuser in use. The infuser is shipped from the factory with one of the configurations described in Table 1-2. The infuser configuration is easily identified by the end cap color. Table 1-2. Therapies

POWER SOURCES The infuser can be powered by two internal AA disposable batteries, an external rechargeable battery pack, AC mains adaptor, or docking station. External supply voltage must not exceed 3.3 VDC. Install two fresh, disposable AA batteries for backup power when using an external power source. The infuser will continue to operate on backup power if the external power source fails.

 Note: Use of internal rechargeable batteries is not recommended. Always connect to a grounded AC outlet when using an AC adaptor. Use only an AC adaptor specifically labeled for use with the Hospira GemStar to charge the battery pack CAUTION: Inspect the disposable AA batteries for leakage, corrosion, or other damage prior to each use. CAUTION: During charging, if the battery pack becomes hot to the touch, immediately disconnect from AC power and contact Hospira. CAUTION: Do not touch exposed connectors on the bottom of the infuser. Exposed connectors are susceptible to electrostatic discharge (ESD) damage.

OVERVIEW

1.8.4

OPERATION The infuser is microprocessor-based and is programmed using a 23-key keypad on the front of the device (see Figure 1-1). The 16-character-by-4-line backlight display indicates the status of the infuser. The Hospira GemStar has up to seven therapies available, depending on its configuration. Delivery rates and Bolus dosage amounts are programmed in milliliters (mL), milligrams (mg), or micrograms (mcg). A loading dose is programmable for immediate or delayed delivery. Bolus doses can be programmed to begin delivery on-demand. To program the infuser, the operator selects the following: - Therapy type - Delivery type: volume delivery (mL), or mass delivery (mg or mcg) - Concentration (only if mass delivery is selected) - Delivery rate - Loading dose, if desired - Bolus dose, if desired - Total amount to be delivered: Volume to be infused (VTBI) If mass delivery is selected, the infuser automatically converts mg or mcg to the nearest number of tenths-of-mL. The amount of fluid delivered is shown on the display. When a Bolus is programmed, a minimum lockout time between Boluses must also be programmed. In addition to the lockout time, the operator can also program the maximum total volume that can be delivered in a selected period. The infuser contains a time-of-day clock and event history storage capability. Program settings, significant events that take place while a protocol is running, and the associated time and date, can be reviewed on the display. The event history can be printed to a compatible printer or downloaded as an ASCII text file to a computer with the use of the serial printer cable. For specific instructions regarding infuser operation and optional system components, see the System Operating Manual.
