Tandem RELiZORB Instructions
A single RELiZORB may be used for up to 500 mL of enteral formula, and up to two RELiZORBs can be used
in a day (24-hour period). For enteral tube feeding formula volumes greater than 500 mL and up to 1000
mL, you can follow the Instructions for Use (www.RELiZORB.com/IFU); using one cartridge per 500 mL,
or connect two RELiZORBs together in a tandem configuration. The Tandem configuration (two cartridges)
is limited to one such use per day. Tandem RELiZORB may also be referred to as "piggy backing".
Tandem RELiZORB was evaluated with a pump flow rate of 120 mL/hr. to run 1000 mL of formula. Some enteral
tube feeding formulas may exhibit slower flow rates with Tandem RELiZORB at volumes greater than 500 mL.
For complete product use information, please see the
Instructions For Use
and Patient Guide.
Tandem RELiZORB set up procedure and use
- Set up the pump and feed set per the pump manufacturer’s instructions. Prime the feed set per the manufacturer’s instructions.
Remove two RELiZORB cartridges from their pouches. Examine each RELiZORB. Do not use a RELiZORB cartridge if:
- the pouch seal is broken
- the RELiZORB cartridge is damaged
- the RELiZORB cartridge has been previously used
Join the two RELiZORB cartridges by inserting the outlet fitting from the first RELiZORB into
the inlet of the second RELiZORB with a twisting and pushing motion until secure as shown in
FIGURE 1. Connecting two RELiZORB cartridges together to form a tandem RELiZORB.
Secure the tandem RELiZORB to the end of the feed set tubing by inserting the outlet fitting
from the pump tubing into the inlet of the tandem RELiZORB with a twisting and pushing motion
until secure as shown below in Figure 2.

- Follow the pump manufacturer’s instructions to prime the feeding formula through both cartridges
to the outlet of the tandem RELiZORB.
Connect the tandem RELiZORB outlet fitting to the inlet fitting of the pump extension set that
connects to the patient as shown in Figure 3.

Follow the pump manufacturer’s instructions to prime the feeding formula to the end of the pump
WARNING: If medications, saline flushes or other non-enteral formula materials
are to be added, they must be introduced AFTER the tandem RELiZORB (i.e. between tandem RELiZORB
and the patient). They may be added to the side-port of a Y-connector extension set located
between the tandem RELiZORB and the patient as shown below in Figure 4.
FIGURE 4. Medications may be added between the tandem RELiZORB and patient.
NOTE: If medications or flush solutions are added BEFORE the tandem RELiZORB, then
both RELiZORB cartridges, all tubing and formula must be discarded.
