Fillers
The Spectra system uses four different fillers (see Figure 2-6). The system
performs each apheresis procedure using a specific filler. For information
about which filler to install, see “Removing and Installing the Filler” on
page 4-2, or refer to the procedural guides.

Return Flow Controller
Use the COBE Spectra Return Flow Controller to perform Single-
Needle ELP, LRS, LRST collections and Single-Needle TPE procedures.
The Return Flow Controller has two functions:
•
Holds the Single-Needle bag, which contains blood components the
system removed from the donor/patient during the Draw phase of a
Single-Needle procedure. The system returns the components to the
donor/patient during the Return phase.
•
Provides controlled pressure on the Single-Needle bag during the
Return phase of a Single-Needle procedure.
For an explanation of the symbols that appear on the Return Flow
Controller’s front cover, see Figure 2-12 on page 2-20. This information
also appears on the permanent label on the back cover of the unit.
Caution: You must use the Return Flow Controller to perform a
Single-Needle procedure. DO NOT attempt to perform a Single-
Needle procedure without a Return Flow Controller and
appropriate disposable tubing set.
