3. Open the chart recorder cover at “A.” Remove the pen cap. Retain the
pen cap as it must be replaced after the procedure to prevent the pen
from drying out.
4. Inspect the tubing and the stopcock coming from the pressure trans-
ducer. It must be completely free of bubbles. Inject sterile water with
a very long needle to displace any bubbles present. Use a syringe to
add water to the stopcock to form a positive meniscus.
5. Assemble the following sterile components in a sterile field per :
Syringe, Filter, 3-way Stopcock, MiniMed refill needle (MMT-4102)
Prime the stopcock, filter and needle using the RINSE BUFFER from
the syringe. Form a positive meniscus on the end of the filter.
6. Carefully join the 2-way stopcock to the filter. A sterile person must
hold the filter assembly and a non-sterile person must hold the stop-
cock. From this point, the sterile person will manipulate the needle
and stopcock to perform the measurements.
7. Push switch 7 to “I Pen.” This puts the pen in contact with the paper.
8. Set the “0” adjustment. Maintain switch 3 to the right position and
adjust the thumbwheel 4, until the pen is at “0.”
9. Initialize the chart by pushing switch 6 to the right “Prot” momen-
tarily. The pen will write the chart settings.
10. Tape the transducer securely to a table or any stable surface roughly at
the level of the implanted Pump. Hold the refill needle at the level of
the patient’s pump and open both the 2-way and the 3-way stopcocks.
(The 3-way stopcock is opened to allow flow between the filter and
needle but not to the syringe.) The monitor should display 0 (zero) or
a very low number. Close both stopcocks. (The 3-way stopcock is
opened between the syringe and the filter; the needle is closed.)
