You Can Decompress
While You Feed!
• To avoid a “balloon burst” use your
MIC-KEY* GJ Feeding Tube, as indicated
in the Instructions For Use (IFU).
• To avoid damage, always use the correct
equipment. Only use the extensions sets
as instructed by a clinician. Only use
a syringe for its intended purpose.
• Replace extension sets as per the IFU.
• Only use sterile or distilled
water to fill your balloon.
• A medical professional will determine
the proper length of the tube by using
a stoma measuring device and then
recommend the proper length. If
there are issues with the tube, stoma
or significant weight is gained or lost,
contact a medical professional. A new
measurement could be required.
• The external base of the feeding tube
should rest just above the skin surface.
A good fit is considered 1 to 2 mm
above the skin, about the thickness of
a dime. If the external base is sitting
too low or high, contact your clinician
to see if you need to be re-measured.
• Refer to the IFU or the first page of this
guide for the inflation volumes of your
balloon. It will vary based on tube size.
• Only use water-soluble lubricant.
• The MIC-KEY* GJ Feeding Tube features
an anti-reflux valve, located toward the
top of the feeding port. When you attach
the extension set, this valve is opened
to allow feeding. It is important to keep
both the feeding port and the anti-reflux
valve clean with proper flushings.
• To avoid valve damage, do not
insert medication or nutrition directly
into the feeding port valve.
!CAUTION: Do not push cotton-tip
applicators or other objects through
or into feeding port valve
Using the MIC-KEY* GJ Extension Set
TO CONNECT
Insert the MIC-KEY* GJ Extension
Set into the port labeled “Jejunal”
by matching the black lines on the
extension set with the jejunal feeding
port. Lock the set into place by
turning the connector CLOCKWISE
until you feel a slight resistance.
TO DISCONNECT
Disconnect the extension set from the
MIC-KEY* jejunal feeding tube port by
rotating it COUNTER-CLOCKWISE until
the black line on the feeding port lines up
with the black line on the extension set.
Gently detach the extension set and cap
the MIC-KEY* GJ gastric and jejunal ports
with the attached feeding tube cover.
Replacing the MIC-KEY* GJ Feeding Tube
Your clinician will decide when to replace the MIC-KEY* GJ Feeding
Tube. See your medical care team if you are experiencing any of
the following and request your stoma length be checked with the
MIC-KEY* GJ Stoma Measuring Device (SMD):
1. Significant weight gain or loss
2. Tube pinches or feels tight
3. Tube appears too loose
4. Stoma is uncomfortable and/or irritated
