Test procedures (continued)
4.
Zero scales or burette. Press
5.
The pump will automatically pump at 125ml/h for a total of 20ml, which will take approximately 9½ minutes. During the run, it
will display the volume infused up to that point and intermittently flash "r" with the run indicator, to show that this is a
verification run. At the end of this run, the pump should display "20.00" and "wait".
6.
Allow the scales to settle and then note the reading on the scales. If using a burette, take the final reading of volume infused.
The volume infused should be 20.00ml ± 5%.
7.
Press the
key and the pump will revert to the technical service entry mode and flash "CodE", followed by "0", enabling you to
begin other tests if required. Switch the pump "OFF" if there are no further tests to be done at that time.
Flow Stop Mechanism Test
It is necessary to check that the flow stop device can hold sufficient pressure and thus prevent free flow.
1.
Load set into the pump. Use same setup as for pressure calibration (see Chapter 2 Configuration & Calibration).
2.
Open the door and check that the arm stays in the UP position by lifting the arm onto the ledge.
3.
Close the door fully.
4.
Reopen the door and note that the flow stop arm has activated into the down position.
5.
Pull the test tubing out of the pump and place the tube in front of the flow stop mechanism arm in the down position.
6.
Close the door and reopen the door. Check the tubing locator has loaded the tube fully under the clamp and is flat. This checks
whether the tubing locator is the correct way around and works.
7.
Ensure the door is open and the flow stop is closed. Apply 650mmHg to the distal end of the IV infusion set for 10 seconds. Then
reduce pressure to 500mmHg to the distal end and verify pressure gauge reading is 500mmHg. Ensure the pressure does not
drop by more than 15mmHg in 30 seconds.
