AK 98 Dialysis Machine - Disinfection and cleaning A:157
Frequency Activity Result
After each treatment 1. Run a heat disinfection program (with or
without citric acid), or a short heat citric
program.
2. Wipe the outside of the dialysis machine
with 70% ethanol or 60% isopropanol.
3. Rinse the outside and flush the inside of
the pick-up tubes with water. Let them dry
naturally.
Disinfection
At least after every 3rd
treatment
1. Run a heat disinfection program together
with CleanCart C cartridge.
Cleaning

Disinfection
At least once every 7th
treatment day
1. Run a chemical disinfection program with
sodium hypochlorite.
A heat disinfection program together with
CleanCart C cartridge shall be performed
before a sodium hypochlorite program.

Every 1-3 months if
UFD is installed
1. Change the ultrafilter.
2. Run a heat disinfection program.
Disinfection
Table 10-2. Cleaning and disinfection schedule
Additional constraints if ultrafilter U9000 is used:
ā Disinfection using sodium carbonate, e.g. CLEANCART A cartridge, shall not be
performed before periods when the machine is inactive, e.g. storage over
weekend.
ā The recommended process of heat disinfection using CLEANCART A cartridge
shall be followed by heat disinfection using CLEANCART C cartridge the same
(working) day and shall preferably be performed in the middle of the working week.
10.7.3 Flow path
During treatments, the flow path can be soiled by calcium-carbonate from the dialysis
fluid, or fat, protein, and organic material from the patient. The dialysis machine has
decalcification and cleaning programs to take care of this, see Section 10.3 āHeat
disinfectionā on pageīA:145.
The number of treatments and the setting of parameters will influence the amount of
deposits downstream of the dialyzer.
An increased level of cleaning may be necessary, depending on the conditions
described above. To see a general schedule for cleaning, go to Section 10.7.2
