6. Insert the refill needle back into the Pump fill port with the stopcock closed.
7. Open the stopcock and empty the Pump. Allow 30 seconds after the
INSULIN level appears to have stopped rising in the refill syringe to assure
the Pump is completely emptied.
8. Close the stopcock and remove the syringe.
Fill the Pump with insulin
1. Remove another refill syringe (IN2) from a refill kit package.
2. Firmly attach the two-way stopcock to the refill syringe and attach an 18
gauge needle to the stopcock. Label the syringe IN2.
3. Draw 20 mL of INSULIN (two vials) into the IN2 syringe.
4. Remove the 18 gauge needle and expel all air bubbles in the syringe.
5. Close the stopcock.
6. 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.
7. Shake vigorously for a minimum of 30 seconds to degas the INSULIN.
8. Point the syringe tip upward and slowly open the stopcock to vent the
syringe.
9. Release the locking ring on the refill syringe.
10. Expel the air in the syringe and carefully observe it to ensure no air bubbles
remain in the syringe. If air bubbles are noted, repeat steps 5 - 10.
11. Fill the hub of the refill needle with INSULIN and attach it to the stopcock.
12. Prime the needle and close the stopcock.
13. Place a sterile beaker or sterile barrier towel on the scale and tare it (position
balance at 0.)
14. Weigh the refill syringe and record the weight on the Implant Worksheet.
15. Insert the refill syringe into the Pump fill port, open the stopcock and allow
the Pump vacuum to draw INSULIN into the reservoir until the fluid level
stops moving. Close the stopcock.
