100 Using bacterial filters
USING BACTERIAL FILTERS
If the device is intended for use by more than one patient
(e.g., operation in clinics), a suitable bacterial fi lter (e.g.,
MEDISIZE BARR-VENT S) must continuously be used to
protect the device from contamination by human pathogens.
Change the bacterial fi lter daily and follow the man-
ufacturer’s user’s manual.
If the optionally available humidifi er aquapoint 2 is used
with the device, a bacterial fi lter must not be used.
On a change of patient, carry out the following steps:
• Replace the bacterial fi lter.
• Disinfect all the parts of the housing and the connec-
tions with a suitable agent, e.g., Mikrozid® Liquid.
•
Change the fi lter or if you are using the optionally avail-
able fi ltersystempoint 2, either change its coarse and
fi ne fi lter and disinfect the surface of the fi lter system
or replace the entire fi lter system with a new one.
If there is any doubt, it should be assumed that the
device is contaminated and it should be hygienically
prepared according to the hygiene concept.
