Equilibrate and pull insulin through system
The reservoir pressure in the Pump is equilibrated with outside ambient pressure
and INSULIN is pulled through the fluid system. This procedure uses the follow-
ing volumes in syringes 6 and 7:
• Syringe 7 with residual INSULIN from previous step.
• Syringe 6 with 5 ml solution. To perform this procedure with syringes 6 and
7, follow the steps below:
Syringe 7: Insulin - Residual
1. Maintain syringe 7 with approximately 10 ml of residual INSULIN in the
Pump fill port. Verify that the stopcock on syringe 7 is open.
Syringe 6: Insulin - Residual
1. Prime the syringe 6 needle. Close the stopcock.
2. Obtain a vacuum in syringe 6 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 side port with syringe 6 - stopcock closed.
4. Open the stopcock on syringe 6.
5. Using the PPC, program and deliver a 4 unit bolus.
6. Observe syringe 7. If the level of INSULIN approaches 2 ml, close the
stopcock to prevent air from entering the Pump. Observe syringe 6. At least 1
ml of INSULIN must pass into syringe 6 to assure removal of all the RINSE
BUFFER from the side port. If less than 1 ml enters, repeat the bolus from
Step 6, some Pumps may require 3 successive boluses to obtain 1 ml.
7. Close both stopcocks. Remove syringe 7 from the Pump. Set aside the
syringe to be weighed.
8. With the stopcock closed, remove syringe 6 from the side port. Syringe 6 will
have a vacuum from the previous step. Enter the Pump fill port with syringe
6 and open the stopcock to remove 2 ml. This will restore the negative
pressure safety feature of the Pump.
9. Close the stopcock, remove syringe 6 from the Pump, and set it aside to be
weighed.
