Remove insulin from the Pump and fill with NaOH
INSULIN is removed from the Pump and then the Pump is filled with
NaOH. The following volumes are used:
Syringe 1 - 5 ml RINSE BUFFER
Syringe 2 - 20 ml Naoh
Syringe 3 - 30 ml NaOH
Follow the steps below to perform this procedure:
Syringe 1: Rinse Buffer
1. Prime the needle. Weigh the syringe and record the weight on the
refill form (Line A).
2. Close the stopcock. 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.
3. Enter the Pump with the refill needle.
4. Open the stopcock; withdraw the INSULIN. After the INSULIN
appears to have stopped rising in the syringe, wait an additional 30
seconds to make sure all of the INSULIN and air is removed.
NOTE: Air in the Pump System has been shown to be a
significant contributing factor to aggregation of
INSULIN. Proper degassing of all solutions that
enter the Pump is essential.
5. When the 30 second time has elapsed, close the stopcock, remove the
syringe. Weigh the syringe and record the weight on the refill form.
Discard the INSULIN in the syringe except for a 5 ml barrier. This
syringe will be used to pull NaOH through the side port. Attach and
prime a new refill needle.
