Recommended annual functional and accuracy tests
The pump should be inspected, lubricated and tested at least once a
year, to confirm to IEC 60601-1. The initial checks and lubrication are
described on the preceding pages.
Once you have completed the initial checks, you must carry out the
functional and accuracy tests that are here.
To perform these tests, a suitable drain-away system must be
available for expended fluid. Use only a 20 drops/ml non-checkvalve
set, and sterile water or normal saline as the solution. Verify the
pump is switched for primary operation before commencing the
check.
A sample checklist is provided as a record keeping suggestion (see
page 7-18) and the paragraph numbering given below corresponds to
the numbers in the check list.
WARNING: Do not perform these tests while the pump is in use on a patient,
as this may cause patient injury or death.
1. Power up/self test
With the AC power switched on and the power lead connected to the
pump, verify that the green LED (charge) lights.
Note: The green LED only lights when the pump is plugged into a live AC
outlet.
Turn the pump on and verify that all the LEDs light, and all the
segments in the rate and volume to be infused displays are lit briefly
(8s appear in all digits).
Verify that the hold LED is lit continuously, and also that the
primary LED is lit.
Verify that the Message Display briefly shows a checkerboard
pattern, the backlight is on, and the display shows a screen
something like this:
2. LCD contrast/LED brightness
Verify that the Message Display is readable from an angle of
approximately 20 degrees above and below.
Cover the photo sensor and verify that the LED display intensity
decreases.
Now uncover the photo sensor and verify that the LED display
intensity increases.
