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 syringes 2 and 3:
• Syringe 2 with RINSE BUFFER. Expel all RINSE BUFFER
except 5 mL. Change the refill needle if desired.
• Syringe 3 with residual RINSE BUFFER from the previous sec-
tion.
Syringe 3: Rinse Buffer
1. Maintain syringe 3 with approximately 10 mL of RINSE BUFFER in
the Pump fill port. Verify that the stopcock on syringe 3 is open.
Syringe 2: Rinse Buffer (residual)
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 RINSE BUFFER
approaches 2 mL, close the stopcock to prevent air from entering the
Pump. Observe syringe 2. When at least 1 mL of RINSE BUFFER
has entered syringe 2 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 2
and set aside syringe 3 to be used later to remove the RINSE
BUFFER.
