Syringe 3:NaOH (degassed)
14. Prime the needle. Close the stopcock.
15. Enter the Pump fill port with the refill needle.
16. Open the stopcock and allow the Pump to fill completely with NaOH.
When the Pump is filled, approximately 10 ml will remain in the
syringe. Leave this NaOH in the syringe, and leave this syringe in
place for the next step.
Equilibrate and pull NaOH through system
The reservoir pressure in the Pump is equilibrated with outside ambient
pressure and NaOH is pulled through the pumping mechanism. This pro-
cedure uses the following volumes in syringes 3 and 1:
• Syringe 3 with residual NaOH from the previous section.
• Syringe 1 with 5 ml insulin/buffer mixture from previous section.
Syringe 3: NaOH (residual)
1. Verify that the stopcock on syringe 3 is open .
2. Prime the needle. Close the stopcock .
3. Obtain a vacuum by pulling back on the plunger until it locks. Press
the lock into the plunger groove to be sure it is firmly secured.
4. Enter the side port with the stopcock closed.
5. Open the stopcock.
6. Program and deliver a 4 unit bolus to open the valve in the Pump
mechanism.
7. Observe syringe 3. When the level of the NaOH approaches 2 ml,
close the stopcock to prevent air from entering the Pump. Observe
syringe 1. At least 1 ml of NaOH must pass into syringe 1 in order to
thoroughly clean the Pump mechanism. If less than 1 ml enters, repeat
