Piggyback Function
The piggyback-mode offers the possibility to interrupt the current (primary)
infusion temporarily in order to administer a piggyback (secondary) infusion.
Above the pump the piggyback-infusion line is connected with a Y-connector to
the administration set. The secondary infusion is supposed to be located approx.
20 cm higher than the primary infusion. All infusion lines need to be completely
primed. A back check valve has to be placed according to the drawing (see next
page).
A precondition to start the piggyback function is that the pump is stopped.
Note:
Please mind to set a VTBI of the primary and secondary infusion that
corresponds to the size of the container. The piggyback infusion can be delivered
in continuous mode or dose over time mode only.
•
Enter the rate manually or load into the pump via the dose rate calculation or the
drug library. It is not possible to begin with the secondary infusion if the data for
the primary infusion (rate and VTBI) is not set. To enchase comfort list of drugs can
be adjusted to secondary mode by DrugLib.

done manually or automatically. Correspondingly, if an automatic change is to be

The rate and VTBI of the secondary infusion can be loaded via the dose rate
calculation, the drug library or are to be entered manually with

f
. Device delivers the piggyback
volume with the set piggyback rate.
Symbols in the headline of the run display ("PRIM" or "PIGY") will indicate if the
primary or secondary infusion is currently running.
When the piggyback volume is infused the pump automatically changes to the
primary infusion if this was selected. If the VTBI of primary infusion is infused
the pump will continue with the KVO-rate respectively after the KVO-operation
the pump stops and activates an alarm. If a manual change from secondary
infusion to primary infusion was selected, the pump will stop or continue with
KVO after the secondary infusion is completed and the user manually has to
change via the menu item “Change to PRIM“ in the Main Menu to the primary
infusion and start with
s
f
.
Note:
VTBI must consider volume for KVO.
Note:
Switching manually between primary and secondary infusion in the Main
Menu is possible at any time while the pump is stopped. It is recommended to
keep the roller clamp of the non-active infusion closed.
The piggyback therapy can be repeated many times by changing the piggyback
medicament or by reset of the piggyback medicament.
