Pump refill procedure
73
Prepare the refill syringe for filling the Pump
1. Firmly attach a stopcock to the IN refill syringe and attach an 18 gauge
needle to the stopcock. Draw 20 ml of U-400 insulin into the syringe.
2. Expel all air from the refill syringe. Close the stopcock and remove the 18
gauge needle.
3. Retract the plunger until it locks into place. This should be no further than 55
ml - do not go beyond the vent hole. Press the lock into the plunger groove to
be sure it is firmly secured.
4. Shake vigorously for a minimum of 30 seconds.
5. Point the syringe tip upward and slowly open the stopcock to allow air to
enter the syringe.
6. Release the locking ring on the refill syringe. With the syringe pointed
upward, push on the plunger to expel the air and prime the stopcock.
7. Open the stopcock and prime the refill needle. Attach the refill needle to the
stopcock. Close the stopcock.
8. Inspect the syringe to ensure there are no air bubbles. If air bubbles are noted,
remove the refill needle and repeat steps 2 - 8.
9. Weigh the IN syringe and record on the refill form.
10. Set the syringe aside.
Empty the Pump
1. Obtain a vacuum in the RB syringe by pulling back on the plunger until it
locks. Press the lock into the plunger groove and be sure it is firmly secured.
2. Locate the fill port by centering the template over the Pump. The center hole
in the template should be directly over the Pump fill port. Insert the 18 gauge
guide needle into the Pump fill port. Local anesthesia may be used prior to
insertion of the 18 gauge needle.
3. Press the primed refill needle (attached to the RB syringe) into the Pump fill
port, by sliding it through the 18 gauge guide needle. Pull back slightly
(approximately 2 mm) on the guide needle to allow the refill needle to enter
the Pump fill port and actuate the inlet valve.(See Figure 13)
