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 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 PROCEDURE CAUTION: Infuser damage may occur unless proper care is exercised during unpacking and installation. CAUTION:

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

The instrument installation procedure 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.

SECTION 1 INTRODUCTION

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 (see Section 6.1, Technical Assistance). Inspect the infuser periodically for signs of defects. 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 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 - ROM checksum calculation - Motor control test - Stuck key test - PIC watchdog test - CONFIG register test - Battery voltage test - Power loss completion test - CRC verifications on all RAM areas protected by CRCs - CRC on calibration data stored in the EEPROM - Calibration data verification 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: - 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. See Figure 1-1 for an illustration of the infuser.

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. CAUTION: To assure proper operation when using internal batteries, always replace both batteries with fresh, disposable AA batteries when a change is required. Use of rechargeable batteries in the battery compartment is not recommended. CAUTION: Always connect to a grounded AC outlet when using the AC adaptor. Use only an AC adaptor specifically labeled for use with the GemStar® to charge the battery pack. During charging, if the battery pack becomes hot to the touch, immediately disconnect from AC power and contact Hospira Technical Support Operations. CAUTION: Do not touch exposed connectors on the bottom of the infuser. Exposed connectors are susceptible to electrostatic discharge (ESD) damage.

OVERVIEW

1.8.5

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 infuser has up to seven therapies available, depending on its configuration. Delivery rates and bolus dosage amounts are programmed in one of three units of measure: milliliters (mL), milligrams (mg), or micrograms (mcg). A loading dose is programmable for immediate delivery 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 closest 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. The 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 GemStar® serial printer cable. For specific instructions regarding infuser operation and optional system components, refer to the system operating manual.

WARRANTY Subject to the terms and conditions herein, Hospira, Inc., herein referred to as Hospira, warrants that the product shall conform to Hospira's standard specifications and be free from defects in material and workmanship under normal use and service for a period of one year after purchase. Hospira makes no other warranties, express or implied, as to merchantability, fitness for a particular purpose, or any other matter. Purchaser's exclusive remedy shall be, at Hospira's option, the repair or replacement of the product. In no event shall Hospira's liability arising out of any cause whatsoever (whether such cause be based in contract, negligence, strict liability, other tort, or otherwise) exceed the price of such product, and in no event shall Hospira be liable for incidental, consequential, or special damages or losses or for lost business, revenues, or profits. Warranty product returned to Hospira must be properly packaged and sent freight prepaid. The foregoing warranty shall be void in the event the product has been misused, damaged, altered, or used other than in accordance with product manuals so as, in Hospira's judgment, to affect its stability or reliability, or in the event the serial or lot number has been altered, effaced, or removed. The foregoing warranty shall also be void in the event any person, including the Purchaser, performs or attempts to perform any major repair or other service on the product without having been trained by an authorized representative of Hospira and using Hospira documentation and approved spare parts. For purposes of the preceding sentence, “major repair or other service” means any repair or service other than the replacement of accessory items such as batteries, flow detectors, detachable AC power cords, and patient pendants. In providing any parts for repair or service of the product, Hospira shall have no responsibility or liability for the actions or inactions of the person performing such repair or service, regardless of whether such person has been trained to perform such repair or service. It is understood and acknowledged that any person other than a Hospira representative performing repair or service is not an authorized agent of Hospira.
