3. Secure the slide clamp as close to the extension set Luer lock connector
as possible. This should assure a minimum water loss from
the tubing when the syringe is removed.
4. Weigh the entire Medication Cassette Reservoir/extension set and
record the weight. This is the predelivery weight. (This weight
includes the empty Medication Cassette Reservoir, extension set,
and weight of the water.)
5. Attach the cassette to the pump. Program the Reservoir Volume to
20 ml. Now press ¤. This value is the intended delivery volume.
(1 ml of water at 20°C weighs 1 gram.) Remove the slide clamp.
6. With the pump in Lock Level 0, program a Continuous Rate of 125
ml/hr. Start the pump and wait for the reservoir volume empty
alarm. The pump will deliver 20 ml.
7. Again, secure the slide clamp as close as possible to end of the
extension set Luer lock connector. Remove the cassette from the
pump and weigh the entire Medication Cassette Reservoir/extension
set assembly. This is the postdelivery weight.
8. Calculate the difference in weight between the predelivery weight
and the postdelivery weight. This is the weight of the amount
delivered.
9. Find the difference between the volume of the amount delivered
and the intended delivery volume. This is the inaccuracy volume.
10. Divide the inaccuracy volume by the intended delivery volume and
multiply by 100. This is the accuracy error percentage.
11. If the accuracy error percentage is greater than ± 6%, repeat the
test with a new Medication Cassette Reservoir. If the pump fails
a second time, call Smiths Medical MD, Inc. or Smiths Medical
International Ltd.
