This outer edge is raised around the outer aspect of the side port, in
order to help guide the needle into the port.
Accessing the pump inlet
To enter the Pump fill port or the side port, make sure the refill syringe
stopcock is closed, then pass the MiniMed refill needle (MMT- 4102)
through the 18 gauge guide needle. Pull back slightly (approximately 2
mm) on the guide needle to allow the MiniMed refill needle to enter the
Pump fill port or the side port. The refill needle entry opens the inlet
valve of the Pump fill port.
After passing through the septum and seating in the valve, you can feel
the increased force, about 0.5 pounds, required to move the valve 0.5 mil-
limeter to open. Maintain this downward pressure in the pump fill port to
ensure that the inlet valve remains open.
In the case of the side port, a downward pressure is not required after the
needle is completely inserted.
