1.4 SIGMA SPECTRUM INFUSION PUMP SPECIFICATIONS

Applications

-Large and small volume parenterals

-Neonatal

Administration Set

Compatible with standard gravity IV sets supplied by Hospira® and several other companies, (consult SIGMA for a complete list of compatible standard IV sets).

Performance

See Appendix A for additional specifications.

Downstream occlusion time to alarm for occlusion pressures adjusted to LOW (6 psi), MEDIUM (13 psi), and HIGH (19 psi) *:

RATE	LOW(6psi)	MEDIUM(13psi)	HIGH(19psi)
5 mL/hr	<5 min.	<10 min.	<20 min
100 mL/hr	<15 sec.	<20 sec.	<40 sec.
Max. Bolus	0.25 mL	0.50 mL	0.80 mL

*With Occlusion 45 inches below the pump and alarm set to LOW, MEDIUM or HIGH.

Trip pressure specifications for downstream occlusions are:

Pressure Setting	Nominal Value (psi)	Tolerance (psi)
Low	6	±4
Medium	13	±6
High	19	±9

All safety related sensing systems are automatically checked for proper operation periodically during set up and pump running conditions. Faults are identified by SYSTEM ERROR codes.

Effect of Fluid Container Height1.

The performance of the infusion pump will be influenced by the forces of gravity on the fluid being administered to the patient. When a fluid container is positioned above or below the patient’s administration site, pressure forces associated with the fluid’s head-height (distance measured from the center of the pumping mechanism to the top of the fluid in the source container) will cause deviations in the nominal specification for device flow rate accuracy. The nominal head-height used for the flow rate and graphical presentation is 24” (61 cm). e.g. The deviation from the nominal flow rate accuracy from +24” to -20” (-51 cm) head-height has an influence of a possible -4% in flow rate accuracy when the flow rate is set to 25 mL/hr.

1. Note: Liquid container must be vented or a collapsible bag.

Bolus Accuracy

The SIGMA Spectrum IV Pump may have an optional bolus mode of operation. This feature allows the user to perform a BOLUS SETUP action. To utilize this feature the pump must be programmed with either a specific rate or a specific amount to be delivered in a certain amount of time.

If the pump is currently operating in mL/hr delivery mode, the bolus rate value is entered in mL/hr and the volume is entered in milliliter (mL). If the pump is operating in a non-mL/hr delivery mode (for example mcg/kg/min), the bolus amount would be entered in mcg/kg however the ML/HR soft key may be pressed in the setup screen to enter the bolus information in mL/hr format.

In either mode, the time is entered in minutes and seconds (min:sec). Limits are placed on the minimum and maximum amount of time for the bolus delivery. The limit constraints are contained within the software of the Spectrum pump and are necessary to control the maximum or minimum flow rate of the bolus infusion.

P/N 41019 Rev W

SIGMA SPECTRUM INFUSION PUMP - SERVICE MANUAL

The accuracy of the bolus volume is dependent up the resultant flow rate that is obtained from the calculation of volume to be delivered in the time requested. For example if the maximum bolus volume is 300 mL, the maximum flow rate is obtained with a bolus time of 18:02 (min:sec) or a flow rate of approximately 999 mL/hr. Using this maximum bolus volume, and delivering the volume in the shortest amount of time, the mean value of 302 mL ± 5% may be expected. Whereas using a minimum bolus volume (.5 mL), and delivering the volume in a reasonably short amount of time (1 minute), the mean value of .52 mL ±16% may be expected.

3.Introduce a 1” minimum air bubble into the IV set upstream from the pump.

4.Verify the pump goes into “AIR-IN-LINE” alarm. Press RUN/STOP.

Memory Test (this assumes you are starting from an all clear point) *

1.Turn the pump on. May ask New Patient Yes/No? Select No.

2.Push “BASIC” and “OK”, “OK”.

3.Set a parameter for “RATE” and “VTBI”.

4.Turn the pump off.

5.Turn the pump on and press No to the New Patient Yes/No screen. Verify the “RATE” and “VTBI” parameters were saved.

Recommended Flow Rate Accuracy Test *

NOTE: Confirm test failures with a new unused IV set.

1.Set the pump’s flow rate to 200 mL/hr.

2.Set the VTBI to 50 mL (length of test ≈ 15 min.) when using a gravimetric method.

3.Set the VTBI to 40 mL using a 50 mL Class A Graduate collection vessel when the volumetric test method is chosen. If a larger Class A Graduate is used a VTBI that is at least 80% of the collection vessel’s maximum capacity should be collected.

4.Hang the IV bag / container 24” above the pumping mechanism.

5.Connect a new IV set to the IV container and prime the set completely. Remove all air from the tubing, being sure the drip chamber is at least half full.

6.Load the set into the SIGMA Spectrum pump and close the door.

7.Place the end of the IV set in the collection vessel so that the fluid output end will not be below the fluid level that is to be collected. The set should be primed so that fluid is at the end of the IV set, but none has dripped into the graduate before starting the test.

8.Begin the test by pressing the “RUN” key. Allow the SIGMA Spectrum pump to run until it goes into infusion complete alarm.

Note: Pumps with v6.00.00 and later software versions will display a CHECK FLOW screen once the pump is started. For purposes of this test, press ‘yes’ to proceed to the normal RUN screen.

9.Press the “STOP” key to halt the KVO (keep vein open) rate once the pump goes into infusion complete.

10.If test is interrupted by any alarms except air, the test can be continued as long as the pump was observed by the tester to have not been in “STOP” for more than ten minutes.

11.Observe the actual volume collected either visually or weighed on the scale.

12.When measuring fluid level visually in the graduate, the level is read from the bottom of the fluid meniscus.

13.Acceptance criteria: collected volumes of ± 5%.

14.When measuring with the scale (gravimetric method):

15.Weigh the collection vessel and water using grams as the unit of measure.

16.Empty and dry the collection vessel.

17.Weigh the collection vessel. The difference between the two measured weights is equivalent to the volume delivered.

18.If the collection volume is within the range of ± 5%, the pump is properly calibrated. If not, return the pump to SIGMA International, Inc. for re-calibration.

AC Power Adaptor Safety Analysis

1.Inspect the SIGMA P/N 35714 AC Power Adaptor for signs of abuse such as cracks in the housing or bent AC main prongs.

2.Verify green LED is lit.

3.Inspect the low voltage supply cord from the AC power adaptor to the pump unit for signs of abuse such as cuts or exposed conductors.

Battery Capacity Test

1.The storage capacity for the battery may be determined by running the Battery Capacity Test.

2.The pump must be connected to the AC power line for at least 12 hours prior to the test, to allow the battery to attain full charge. NOTE: If a Wireless Battery Module is installed the pump must be connected to the AC power line for at least 16 hours prior to the test.

3.The pump can be in use while the battery is charging.

4.Use an IV test set in a loop configuration, so that fluid is circulated around the loop.

5.Turn on the pump and load the IV set into the pump following the display prompts to assure that it is properly loaded. NOTE: If the IV set is not properly loaded the test results will be invalid.

6.Select the Help softkey, User Settings and select Display Settings, the Display Adjust and then select Backlight Level to “High”. Exit to the OPTIONS screen.

7.Select the Biomed Configuration so that the automatic monitoring of the battery capacity test can be selected. Enter the password and select Pump Testing.

8.Select option for “Battery Life Test”.

9.Follow the display instructions. Enter or verify 125 mL/hr for Rate and turn “Low batt alarm” and “Constant alarm” off.

10.Press the OK key and move the cursor to done press OK.

11.Be sure that the pump is unplugged and the “Current battery Level” indicates a fully charged battery (between 8.0V and 8.3V). If battery is fully charged, select “OK”.

12.The pump will run until the battery is depleted and will then power off.

13.After the battery is depleted, plug in the pump’s AC Power Adaptor and power the pump up or power the pump up with a fully charged battery.

14.When the pump is plugged in, it will display the time from the start of the test to depleted battery and it will also display time from low battery to depleted battery (in hr:min format).

15.Pass criteria for a used battery: ≥ 6 hours from “Start to dead” and ≥ 31 minutes from “Low to dead”. NOTE: If a Wireless Battery Module is installed, the pump used battery pass criteria is ≥ 3 hours from “Start to dead” and ≥ 31 minutes from “Low to dead”.

16.Pass criteria after installation of a new battery: ≥ 8 hours from “Start to dead” and ≥ 31 minutes from “Low to dead”. NOTE: If a Wireless Battery Module is installed, the pump new battery pass criteria is ≥ 4 hours from “Start to dead” and ≥ 31 minutes from “Low to dead”.

17.Less battery capacity indicates a battery reaching end of life.

18.See the Battery Removal and Replacement section of this manual for replacement. If a Wireless Battery Module is installed, see the Wireless Battery Module portion of the Battery Removal and Replacement section.
