9. Disinfection
9.11 CENTRAL CONCENTRATE DELIVERY SYSTEMS
Sometimes a white sticky substance may appear in the tubing of
hemodialysis Instruments. The source of this substance could be
the “coily” concentrate tubing used to connect to central Acid
and/or Bicarbonate delivery systems. If you are using the
translucent red, blue or clear polypropylene coily tubing, it will be
damaged by acidic cleaning solutions.
The manufacturers/distributors of this tubing recommend that you
use the PVC version (clear only) if you are using acidic chemicals
to disinfect or decalcify your Instruments. This would include
chemicals like Actril, Renalin, and vinegar.
Please note that concentrate lines longer than the standard will add
volume to your systems and may affect ALL dialysis machines.
For chemical disinfection/cleaning, the time required to rinse any
chemicals may be longer. You can extend the programmed rinse
time in Service Mode as needed.
