8.0 Cleaning / Disinfection

Handling of the suction device determines to a large extent
its reliability and safety. These hygiene measures are
indispensable for protecting the patient and the user and to
maintain the functional safety of the suction device.
In the event in a change of ownership or an oversuction of
the device, professional reprocessing by the manufacturer,
a certified ATMOS partner or a specialist authorised by
ATMOS in accordance with Medical Devices Operator
Ordinance, Medical Devices Act and BVMed rules is
required. (See chapter 9.2 Reprocessing)

8.1 Basic information

• The following cleaning measures must only be performed
if the device was used. When the device is only rarely
used then a function check must be carried out at
intervals of max. 3 months. Only then is the function of
the device guaranteed.
• We recommend that you always document all
maintenance work and part replacements in writing.
• Please use disposable gloves for all work.
• Prior to cleaning the device please remove and dispose
of all disposable items, such as bacterial filter, fingertip
and catheter.
• Prior to cleaning please remove the power cable from the
device.
• The described measures for cleaning and disinfection do
not replace valid rules for operating the device!
• Please observe the instructions for use prescribed by the
manufacturers of disinfectants, especially regarding the
concentration information and information on material
compatibility.
• Attention: Some disinfectant solutions slightly stain the lid
parts and silicone hoses, but this has no influence on the
properties of the materials.
• In the event of a patient change all parts that come
into contact with the suction material (canister, lid,
overflow protection and hose) must be cleaned and then
disinfected. Disposable items such as bacterial and viral
filter, catheters, fingertips, etc. must be exchanged. See
the individual cleaning instructions! (See chapter 8.3)
• If the suction device is used by one patient, the device
and accessories should be cleaned and disinfected
for reasons of hygiene. See the individual cleaning
instructions! (See chapter 8.3)
• Cleaning in an automatic cleaner and disinfecter is also
possible (hose connector, secretion canister and canister
lid). Thermal disinfection is carried out at 93 °C.

8.1.1 DDS bacterial and viral filter

• Replace the DDS bacterial and viral filter after a patient
change. Replace the DDS bacterial and viral filter after 14
days, even if there is no patient change.
• Replace the DDS bacterial and viral filter with a new DDS
bacterial and viral filter if it is discoloured or contaminated
or if oversuction has occurred.
• Always ensure you have a sufficient number of spare
filters on hand.

8.1.2 Suction hose, hose connector and vacuum
hose
• In the event of a patient change the suction hose, hose
!
connector and the vacuum hose must be disinfected with
an instrument disinfectant recommended on page 14.
Please note that the parts should be rinsed with clear
water for at least 10 seconds in order to achieve a better
cleaning effect. Observe the respective instructions for
use of the disinfectants!
• If there is no patient change, we recommend a change
!
every 4 weeks.
• In addition we recommend to thoroughly rinse the hose,
hose connector and vacuum hose with clear water after
each suction procedure and to disinfect them at least
once a day as described above.

8.1.3 Fingertip

• The fingertip is not enclosed in the scope of delivery.
• Prior to using the device on another patient the fingertip
must be exchanged.
• If there is no patient change, we recommend changing
the fingertip daily, for hygienic reasons.

8.1.4 Secretion canister

• The secretion canister must always be disinfected with
!
an instrument disinfectant as recommended on page
14. Please observe that the secretion canister should be
emptied and rinsed with clear water beforehand to ensure
better cleaning. Observe the respective instructions for
use of the disinfectants!
• If there is no patient change we recommend disinfecting
the secretion canister daily as described above.
• For hygienic reasons we recommend to empty the
secretion canister after every suction procedure and to
rinse it with clear water.
) Information on how to remove the canister can be found
in chapter 5.2 on page 9.

8.1.5 Canister lid

• If there is a patient change, the canister lid must
always be disinfected with an instrument disinfectant as
recommended on page 14. Prior to disinfection please
ensure that the DDS bacterial and viral filter has been
removed beforehand and the canister lid is disassembled
into its individual parts (lid, float ball and hose connector).
In order to achieve a better cleaning effect, rinse the
individual parts under clear water for at least 10 seconds.
Afterwards disinfect the individual parts. Observe the
