Fresenius Medical Care 2008K Operator's Manual page 125

The fluid path of the 2008K hemodialysis machine can be disinfected chemically or with
heat. The machine should be rinsed thoroughly after chemical disinfection and before
introducing any other chemicals to the machine. The machine should be disinfected at least
once each day and rinsed per unit protocol. If the machine is not in use for more than 48
hours, it should be disinfected before the next use or put in storage (for more information on
storing the machine, see "Equipment Storage and Maintenance" on page 216). If there is
evidence of a blood leak into the dialysate system, the machine should be disinfected before
being used in any further treatments.
The Rinse program flushes the machine with water. The Acid Clean Program flushes the
machine with a mild acid to remove bicarbonate build up. There are three options for
disinfecting the interior of the 2008K hemodialysis machine—Heat Disinfect,
Chemical/Rinse and Chemical Dwell.
All rinse, cleaning, and disinfecting programs can be interrupted by pulling either concentrate
nozzle from its rinse port or pressing the Escape key. Any Rinse or Disinfection program
clears all SVS and UF parameters and resets them to default values. The ultrafiltration fluid
sampler port output tubing is part of the fluid pathway; therefore, flow exists during cleaning
and disinfection.
The following table describes the cleaning and disinfecting options available on the "Select
Program" screen. Follow the current, chemical manufacturer's instructions for the proper use
of the disinfectants.
Warning!
labeled by the operator. The label should identify the chemical used and state that the
rinsing and testing for residual chemical are required before using the machine for
treatment.

Description
The Rinse program flushes the hydraulic system with water. A rinse
may be done between treatments and must be performed after a
Chemical/Dwell procedure to eliminate residual disinfectant.
The exterior surface of the machine should be wiped down using a
cloth and a disinfecting cleaner.
Bloodlines and transducer protectors should be removed and
disposed of in compliance with your unit's biohazard waste
guidelines. If there is evidence of contamination beyond the external
transducer protector, disinfect the associated parts and replace the
internal transducer protectors.
The Acid Clean button runs a program that flushes the machine
with white distilled vinegar (5% acetic) or 2-5% citric acid for 10-60
minutes to prevent the build up of bicarbonate precipitate in the
hydraulic system after a treatment. It is not a disinfecting procedure.
The Heat Disinfect button starts a program that disinfects the
hydraulic system using water heated to about 80 C. Heat Disinfect
or Chemical/Rinse is recommended daily when the machine is used
for treatment.
