●Do not use this device in MRI (Magnetic Resonance Imaging).
●Do not dry the device with microwaves.
●Chest hoses should not be clamped except when changing the canister. In the event of an airleak, clamping chest
hoses could lead to a tension pneumothorax.
●The ATMOS®S 201 Thorax must remain in an upright position during use.
●The patient should be regularly monitored according to internal hospital guidelines.
●ATMOS®S 201 Thorax is a medical device that requires special safety precautions and must be installed and
placed in operation in accordance with the attached EMC information. Portable and mobile RF communication devices
(mobile telephones) can affect the drainage system.
●A replacement device must always be available for patients for whom a breakdown of the device can lead to a critical situation.
● Do not separate patient hose in-line connector prior to clamping off patient hose  rst.
●Do not keep patient hose clamp closed during drainage collection or patient transport.
● Please note that when the set pressure is -50 mbar or higher this high pressure can cause pain or injuries to the patient.
1.2.2 Intended use of the secretion canister for ATMOS®S 201 Thorax
Name: Sterile secretion canister for the exclusive connection to the ATMOS®E / S 201 Thorax.
Main functions:
Forwarding of the created vacuum into the drainage hose and  nally into the patient side drain.
Collection of the exhausted secretion.
Med. indications/ application: Secretion canister for the connection to a digital device for mobile thoracic drainage.
Specifi cation of the main function:
The vacuum generated by the pump evacuates air and secretion out of the drain. The secretion is collected in the secretion canister
whose  lling quantity is 2 l. A bacterial  lter prevents the potential contamination of the room and the device by bacteria. Additionally
it prevents the accidental intrusion of secretion into the pump head. A sterile tubing system provides the vacuum for the patient side
drain. A direct connection to the patient doesn’t exist. With the support of the test measuring hose inside of the tubing system, which
is also provided with a  lter, the actual vacuum on the drain will be measured. Furthermore the measuring hose is also responsible
for the  ushing of the secretion hose with atmospheric air.
Application organ: Thorax
Application time: Short-term use on the patient (< 30 days).
Application site: Application environment is a clinical area. The application of the canister may only be applied by healthcare
professionals. The secretion canister and the drainage hose are sterile and disposable and can be applied in the sterile OT area.
Contraindications: No application of the canister with other low vacuum devices than ATMOS®E / S 201 Thorax.
The product is: □ active X not active
Sterility: Sterile
Single use product / reprocessing: Sterile single use product

1.5 Function
The ATMOS®S 201 Thorax is a particularly useful small suc-
tion unit. The device is operated by an electromotive, mainte-
nance-free piston pump. During operation the pump creates
a vacuum in the hose system and in the collection jar, with
the help of which secretions can be sucked through the set of
hoses.
The pump switches off after creation of the pre-adjusted
vacuum and switches on again only, when the vacuum lies
below a certain tolerance.
The real-time measured  ow is shown as numerical value. At
one keypress  ow data from up to 12 days are shown in a
graphic.
The secretion is collected in the collection jar, the capacity of
which is 2l. The vacuum at the trocar is measured by means of
the measuring pipe in the set of hoses. The  nal vacuum can
be adjusted with the buttons on the operating foil. If required,
the air- ow rate is automatically adjusted. The device adjusts
and keeps the pre-adjusted vacuum automatically in case the
negative pressure in the pleural cavity varies. In this case the
pump starts to balance the negative pressure until the pre-ad-
justed vacuum is reached again and then switches off. These
compensation values, which may vary heavily, can easily be
read on the display. At regular intervals the device rinses the
suction hose with air so that deposits in the suction hose are
avoided and it prevents secretion from penetrating the
measuring channel.
The device is  tted with a rechargeable battery. A micro-
processor controlled electronic charging unit in the suction
device guarantees the safe charging of the battery, and thus
overcharging of the battery is avoided. In addition a bacterial
 lter located in the cover of the collection jar prevents the entry
of bacteria and secretion into the interior of the device.
There is a carrying strap available for mobile use. A practical
carrying bag and a bed mounting are accessories that can be
ordered.
1.0 Introduction
1.4 Precautions
●Federal (U.S.A.) law restricts this device to sale by or on
the order of a physician.
●Cointainer and hose set are for single patient use and for
one time patient connection only.
●Do not resterilize this device. Canister and hose are
single-use products, there is a high risk of infection in
case of re-use. The canister cannot be emptied .
●Air vent must remain closed at all times when not in use.
●All hospital protocols for disposal handling and infection
controI should be carefully followed.
●The function of the device must be checked prior to use
(see chapter 3.0 – Setting up and starting up; section
3.3 Functional test)
●When a thoracic catheter is connected leaky connections
may result in an incorrect evaluation of air leaks from the
lung and delay treatment time. Therefore check that all
the connections are airtight to prevent air from entering
from the atmosphere.
●During set up, an incorrectly positioned drainage system
and patient hose may impair  uid and air evacuation.
Total obstruction of  uid and air evacuation can cause
an increase in positive pressure and possible tension
pneumothorax. Therefore position the drainage system
below the level of the patient`s chest and check that the
patient hose does not form loops or kinks, impairing
drainage of  uid and air.
●Check that all the connections are airtight.
If the thoracic drainage unit tips over it is advisable to
set it up right again to guarantee operation and to be
able to re-determine the volume and appearance of the
drained  uid. If there is the slightest uncertainty about
the operation of the drainage system after it has tipped
over, it is recommended that a new drainage system be
installed to ensure the patient‘s safety.
● Keep the AC adapter connector away from moisture.
●Keep the power cord away from hot surfaces.
● Do not over ll water seal above the 2 cm  ll line.
● Water seal must be  lled to prescribed level prior to use
and should be checked regularly to con rm proper
operation.
● Use only pre-packaged sterile  uid for  lling the water
seal.
●When inspecting the collection chamber routinely
check the volume and appearance of the drained  uid
and inform the responsible clinician of abnormalities.
Exceeding the recommended collection volume can
cause obstruction of  uid and air evacuation and may
therefore result in an excess pressure pneumothorax.
Always replace the canister when the maximum volume
is reached to ensure the patient`s safety. Replace chest
drain if damaged. Patient hose connections and water
seal, should be checked regularly to con rm proper
operation.
●Installation. The product must be used at room
temperature and should not be placed in direct sunlight
as this may result in measurement errors.
In case of noncompliance and misuse of the ATMOS®S 201
Thorax any guarantee claims shall expire and ATMOS Medizin-
Technik GmbH & Co. KG assume no liability.

4.2 Suction procedure
●After setting the target vacuum the drainage system
builds up and controls the set negative pressure
automatically as long as the pump is switched on.
 The bacterial  lter is a safe protection against liquid
penetrating the pump.
4.3 Hose rinsing
An automatic hose rinsing function will operate periodically.
This rinsing function is designed to draw any secretion or
 uid build-up in the measurement hose into the suction
hose and subsequently the secretion canister.
If the water lock function is being used, air bubbles are
likely to appear during the hose rinsing period. Users
should be aware that these air bubbles that appear at
regular intervals (usually 5 mins), are not related to the
patient’s condition (e.g.  stual).
The hose irrigation is inactive if the actual vacuum
value is between -10 and 0 mbar.
Adjust the target vacuum with the keys▼▲.
The basic setting is -20 mbar. This value can be changed
in the settings menu.
Depending on the selected vacuum unit, the target
vacuum can be set in 1mbar or 1kPa steps.
NOTE: 1kPa = 10mbar, therefore when kPa is selected,
the vacuum range is 1kPa to 10kPa.
●Only use the original ATMOS
single-use secretion canister!
● Vacuum connection
The vacuum connection between the
pump and the collection jar is created
automatically as soon as the secretion
canister is positioned correctly.
Please pay attention to the period tests in
chapter 6.0 „Service and maintenance“ on
page 22.
4.4 Battery recharging
The battery is recharged by the integrated recharging electronics
as soon as you connected the device to the mains supply with
the power cord. Please note the information on how to handle
rechargeable batteries in chapter 6.3.
Charging condition:
Please take care not to expose the device to any source of heat
during recharging as this would reduce the available charging
capacity and increase the recharging period.
Correct handling of the rechargeable batteries prolongs their
maximum service life.
Rechargeable batteries are wearing parts and therefore exclu-
ded from the 2 years‘ product liability!
4.1 Adjust vacuum
●For hygienic reasons we
recommend to exchange the
hose always together with the

4.5.1 Filling the water lock
The water lock is on the right side of the canister. A
bacteria  lter and a riser are included. The water lock is
 lled with water through the riser. For  lling the water lock
a sterile cannula 20 G, a sterile syringe and 50 ml sterile
water are required. With the cannula you may puncture the
silicone seal above the riser and then  ll the water lock.
Repeat this procedure until the water lock is  lled up to the 2
cm  lling mark.
Reconnect the  lled canister to the device as described
under 4.5.3.
During normal operation the  lling of the water lock is
optional.
The canister may only be removed when the pump is
switched off.
Prior to inserting the secretion canister into the device, make
sure that the  ller of the water lock is sealed with the plug.
4.5.2 Pop-off valve
The pop-off valve releases in case of overpressure
(e.g. coughing  ts) .
4.5.3 Insertion of the canister
Connect the  lled canister to the device.
Insert the new canister ( g 9). Insert the rear left edge of the
canister in an angle of approx. 30° to the housing wall and

4.11 Alarm The key lock is automatically deactivated if the alarm is activated!
Display Cause of defect Troubleshooting
Vacuum low
In case the  nal vacuum cannot be reached an
acoustic and optical alarm is released and
„vacuum low“ is readout. Possible cause for this
error message: Leakage, blocked bacteria  lter or
any blockage in the measuring channel or secretion
in the pump.
Check connections and hoses.
Vacuum high
When an excessive vacuum is measured the
„vaccuum high“ alarm is activated (acoustic and
optical).
Check the hose system.
Battery low
In case the battery voltage falls below a certain
value the alarm signal (acoustic and optical) for
„battery low“ is activated.
Connect the device to the mains, batte-
ry is recharged and charging condition
is displayed.
System blocked

Prior to starting up the device the correct function of the visual and acoustic alarm must be checked by the user. In case of alarm
the system switches automatically to the alarm menu. An error message is displayed. Below an information on how to solve the
problem is shown. Simultaneously the acoustic alarm is activated. The LED is illuminated in orange or red.
Before the device can be used, the correct function of the optical and acoustic display must be checked by the user.
Perform the following steps:
1. Attach a canister to the ATMOS®S 201 Thorax.
2. Connect a hose to the unit.
3. Turn on the power.
4. Perform the leakage test.
5. After passing the leakage test, adjust a target-vacuum of 20 mbar or -2.0 kPa.
6. Ensure that the end of the connected tubing set (connection point for drainage) is open - the pressure in the tank-hose
system corresponds to the ambient pressure.
7. Leave the unit for more than 10 minutes in the ON state without starting a vacuum therapy.
8. Wait until the device detects a permanent low vacuum and a corresponding alarm sounds.
9. Check that the display shows an alarm message.
10. Check that an audible alarm signal sounds.
11. Check that the status LED blinks red.
12. If you have performed all the above steps successfully, the correct function of the optical and acoustic displays is suf ci-
ently controlled.

4.13.1 Monitoring the progression of therapy
via micro SD card
Via an integrated mico SD card, REF 312.2021.0, the
stored data can be output in Excel format and assigned
to the patient file. This makes it possible to trace the
progression of treatment at any later time as well.
Please only remove the micro SD card when the
device is switched off.
At the beginning of each data logging session, the time and
date are recorded on the file. Subsequently, the flow and va-
cuum values are saved to the micro SD card every 2 seconds.
Therefore the time for each of the recorded data samples can
be calculated by cumulatively adding 2 seconds to the start
time.
4.14 Connection to the nurse call system
The cable may only be mounted by an electronic
specalist.
Prior to use the device, the nurse call system must be
checked (service menu item).
The ATMOS®S 201 Thorax can be connected to the
nurse call system via the nurse call interface (NCI).
A stereo phone jack 3.5 mm is required. In the case of
an alarm the alarm signalling is transferred to the nurse
call system. During each alarm the contact at the phone
jack which is connected to the NCI jack T-S is closed
for approx. 1 sec. The contact R-S is opened during this
time.
Check nurse call system (NCS):
●Turn off device by pressing and holding
