Chapter 5—Disinfection and Maintenance

Cleaning the Exterior Surface

The exterior of the dialysis machine should be cleaned after every treatment. It can be
cleaned with very dilute (1:100) bleach or other suitable hospital disinfectant. Use surface
cleaning agents sparingly to avoid excess cleaner from entering the interior of the machine.
Rinse off cleaning solution with a water-dampened cloth, especially if a corrosive, cleaning
agent such as bleach is used.
Freshly prepared dilute bleach solution (1:100) is currently recommended by the Center for
Disease Control as a suitable disinfectant for the Hepatitis virus. Because surface
contamination is the general mode of transmission for this type of virus, thorough cleaning of
the 2008T hemodialysis machine exterior is essential.
Caution: Do not use foaming type cleansers or disinfectants containing quaternary
ammonium compounds like N-alkyl (C
These ingredients attack the polycarbonate plastics used in the machine.
The optional bibag connector is connected to the 2008T hemodialysis machine's hydraulics
so running rinse or disinfection programs from the "Select Program" screen will also rinse or
disinfect the bibag connector.
To prevent bicarbonate buildup on the bibag connector:

Clean the exterior of the sealing area of the bibag nozzles with very dilute 1:100 bleach
every day before running a rinse program.

Run an Acid Clean program at the end of every treatment day before running a Heat
Disinfect program.
Warning! A Rinse program must be run after cleaning the sealing area of the bibag
nozzles on the bibag connector to rinse away residual disinfectant.
If a blood leak occurs inside the blood pump module, make sure to clean around the blood
pump rotor. Unlatch and remove the rotor during cleaning.
Figure 61 – The Blood Pump Rotor
Warning! Inspect the blood pump rotor for proper operation (tubing guide posts not bent,
rollers move freely, crank lever moves freely). Bent or loose tubing guide posts can
damage bloodlines. Replace rotor if necessary.
