Venting the Medtronic MiniMed refill syringe (optional)
In order to fill the Pump, it may be necessary to vent the headspace in the
Medtronic MiniMed refill syringe. Refill syringes do not have lubricant on the
syringe housing or on the plunger tip. Some syringes may be “sticky” and require
the venting procedure described below to assist the vacuum in the Pump to over-
come this condition.
To vent, hold the syringe with the refill needle pointing down. Vent the syringe
headspace by pulling back firmly on the plunger until the second sealing ring on
the rubber cap passes beyond the vent hole as shown in Figure 17.
Figure 17: Venting the refill syringe
NOTE: Be sure that the plunger is retracted far enough
that the vent hole is exposed. The syringe must
be held with the needle facing down and used
within 10 minutes once it is vented. If this time
limit is exceeded, repeat the degassing
procedure and re-vent.
