Pump implantation

Figure 8: Testing Pump stroke volume with a pipette
6. Insert the pipette into the hub. A meniscus of fluid will be present in the
pipette. This should be done on a flat surface with the pipette/tubing
assembly horizontal (see Figure 8).
7. Note the exact location of the fluid meniscus in the pipette.
8. Measure the stroke volume by noting the volume displaced by a minimum of
10 pulses. Record the total volume delivered and the number of pulses on the
Implant Worksheet. Divide the total volume delivered by the total number of
pulses used to deliver that volume. The volume per stroke must be between
0.40 and 0.60 µL. Record this value on the Implant Worksheet.
Prepare the Side Port Catheter
The Side Port Catheter (“Catheter”) is attached to the Pump before implantation;
however, it must be primed with INSULIN and inspected before being attached
to the Pump.
Never insert a needle into the connector end of the
Catheter for priming or for testing. There is a preci-
sion sealing surface in the connector that may be
damaged by the insertion of any needle.
1. Keep the Catheter in its package until the Pump is prepared and stroke
volume has been verified. Remove the Catheter from its sterile package and
document the serial number on the Implant Worksheet.
2. Using the last insulin syringe (IN2) from the Pump preparation procedure,
enter the Catheter port cone and push a small volume of insulin out of the
connector end of the Catheter. This primes the proximal portion of the
Catheter and cleans any debris from the connector outlet. Remove the
syringe.
