Operator Maintenance of the Return Flow
Controller
Cleaning
Use a mild detergent to clean dirt and spills other than blood from the
outside of the Return Flow Controller. Use only non-abrasive cleaning
materials to clean the front cover.
To clean the inside of the Return Flow Controller (see Figure 2-7 on
page 2-18), perform the following:
1
Remove the front cover thumb nuts.
2
Slide the front cover up and off.
3
Use mild detergent to spot clean the inside of the Return Flow
Controller as needed.
4
Turn the flow control handcrank as necessary to move the internal
mechanism so you can reach areas that need to be cleaned.
Disinfecting
Disinfect the Return Flow Controller using a ¼% sodium hypochlorite
solution of 1 part commercial household bleach (5% to 6%) to 18 parts
water. Use this solution to wipe blood spills from the Return Flow
Controller. Let the surfaces air dry.
To disinfect spills that cannot be promptly wiped, immerse the Return
Flow Controller for five minutes in a sink containing the ¼% sodium
hypochlorite solution. While immersed, crank the Return Flow
Controller through one full up/down cycle. This ensures all parts of the
Return Flow Controller’s internal mechanism are exposed to the sodium
hypochlorite solution. Immediately rinse the Return Flow Controller
with water, then let it air dry. After disinfection, the Return Flow
Controller should be lubricated by a qualified service technician.
The Return Flow Controller’s materials are all resistant to corrosion from
tap water and most cleaning solutions.
Technician Maintenance of the Spectra
System and the Return Flow Controller
Internal Adjustments
Only a Gambro-trained technician should make internal adjustments to
the Spectra system and the Return Flow Controller.
Preventive Maintenance
To prolong the life and ensure maximum performance of the Spectra
system and the Return Flow Controller, a Gambro-trained technician
must perform the preventive maintenance (PM) procedures found in the
appropriate service PM kit(s). The Spectra system and the Return Flow
Controller have a six-month PM schedule. Gambro BCT recommends a
PM performance compliance window of ±30 days from the PM
anniversary.
Warning: When handling extracorporeal blood circuits, take
adequate precautions to prevent the possible exposure to and
transmission of the hepatitis virus, human immunodeficiency
virus, and other infectious agents.
Caution: Using a sodium hypochlorite solution stronger than
recommended can damage or discolor the system surfaces.
