Equilibrate and pull rinse buffer through system
The reservoir pressure in the Pump is equilibrated with outside ambient
pressure and RINSE BUFFER is pulled through the fluid system. This
procedure uses the following volumes in syringes 4 and 5:
• Syringe 4 with RINSE BUFFER. Expel all RINSE BUFFER
except 5 ml. Change refill needle if desired.
• Syringe 5 with residual RINSE BUFFER from previous step
Syringe 5: Rinse Buffer
1. Verify that the stopcock on syringe 5 is open.
2. Prime the needle of syringe 4. 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. To open the valve in the Pump mechanism, program and deliver a 4
unit bolus using the PPC.
7. Observe syringe 4. When at least 1 ml of RINSE BUFFER has
entered syringe 4, close both stopcocks and remove the syringes. If
less than 1 ml enters, repeat the bolus from Step 6. Some Pumps may
require 3 successive boluses to obtain 1 ml. Discard syringe 4 and set
aside syringe 5 to be used later to remove RINSE BUFFER.
Remove rinse buffer and fill with insulin
The RINSE BUFFER is removed from the Pump fluid system and the
system is filled with INSULIN. This procedure uses the following vol-
umes in syringes 5, 7, and 8:
• Syringe 5 with residual RINSE BUFFER from the previous steps
• Syringe 6 with 20 ml INSULIN
