Disinfection
In spite of the high filtration rate and single use of the bacteria
and virus filters, it is necessary to clean and disinfect at least
once a week all components which come into contact with the
patient respiratory flow. This applies to the flow unit, Ergoflow,
shutter cage and shutter head or shutter block.
All parts of the Diffustik resp. the variant PFTstik can be cleaned
from dirt with a soft cloth using a cleaning solution / weak soapy
water.
All parts of Diffustik resp. variant PFTstik which come into
contact, or could come into contact, with the patient must be
treated with a surface disinfection. Otherwise, these can be
wiped with a soft cloth using a weak soap solution.
When using a disinfectant that has not been tested and
approved by the manufacturer, the following steps must be
observed:
•
Preferably use agents that correspond in composition to
the approved agents. The composition is available on
data sheets, which we can provide on request.
•
Check bactericidal and virucidal effect suitable for the
intended use.
•
Use only disinfectants listed in public databases (e.g.
RKI)
•
Check data sheet for material compatibility with plastics
(especially polyoxymethylene, polystyrene, acrylonitrile
butadiene styrene, Makrolon
®
) as well as metal
•
First test the disinfectant for material compatibility in an
inconspicuous place.
•
During the regular visual inspection for damage, also
pay attention to material changes (discoloration, cracks,
embrittlement...)
•
Observe long-term trend of calibrations for changes in
measuring function
