Hygiene - Chemical Disinfection
Chemical Disinfection - General
CAUTION
Disinfectants may be toxic. The user must therefore take note of
necessary precautions before use. The manufacturer’s instructions
and recommendations have to be followed. Local regulations
regarding the utilization of the different chemicals must be followed.
Local regulations have to be followed regarding approved levels
of disinfectant residues.
After the Chemical disinfection procedure a test for residues must
have been performed prior to connecting to a patient.
CAUTION
During the chemical disinfection program the machine is fi lled with
disinfectant. The disinfectant could be concentrated or already diluted.
If it is concentrated it is mixed with water to the correct concentration
in the machine. The solution is then fi lled in all parts of the fl uid path.
After the dwell time (see "Glossary of Disinfection Terms" on page
8:3) the machine is rinsed and drained. If the machine is not to be used
for a long period of time, it is possible to turn it off during the dwell
time
and then it stays fi lled until it is started again. See "Filling the
machine with chemical disinfectant" on page 8:29 for instructions.
Chemical Disinfectants
Chemical disinfectants may be harmful to the materials used in the fl uid
path of dialysis machines. Disinfectants may also contain additives
that cause foaming or are dif fi cult to rinse out. Solutions based on
peracetic acid (such as the Dialox and Dialox HP disinfectants), sodium
hypochlorite and formaldehyde are compatible with the materials in
the AK 96 dialysis machine, provided that they are used in accordance
with the recommendations in "Disinfection and Cleaning - Chemical
Disinfection" on page 9:8 in part 1. It is essential that the chemical
disinfection program is adapted to the disinfectant used regarding
dilution and dwell time. The machine has to be properly preset by
an authorized technician.
After chemical disinfection procedure a test for residues must have
been performed prior to connecting to a patient. On selecting the
correct test for residues, follow the manufacturers instructions for the
speci fi c disinfectant.
If formaldehyde has been used, note especially that the ultra fi lter used
in UFD must be changed prior to the following treatment. Alternatively
perform additional rinse/drain procedures according to “Residual Test
after Chemical Disinfection” on page 8:31.
Note that it is important to wipe up any disinfectants spilled on the
machine with a damp cloth.
