2.3 Combination options
You can use modules individually or connected in
series of up to three modules.
Another option is to connect up to three modules to
the MEDUMAT ventilation device.
Always operate only one module or one
Medumat at a time. If you use modules
simultaneously, it is possible the supply of
O2will be inadequate.
2.4 Storage
If a module is not used for an extended period, we
recommend the following procedure.
1. Perform a hygiene treatment (see “11. Hygiene
treatment” on page 39).
2. Store the module in dry conditions.

8Safety instructions
EN
3. Safety instructions
3.1 Safety instructions
For your own safety and that of your patients, and in
accordance with the requirements of directive 93/
42/EEC, observe the points below.
General
• Please read these instructions for use through
carefully. They are a constituent part of the
device and must be available at all times.
• Read carefully through the instructions for use
for the accessories used. They form part of the
accessories.
• Before you work with the modules, you must
have understood how to operate them.
• Follow the section entitled “11. Hygiene
treatment” on page 39 to prevent an infection
or bacterial contamination.
• Do not use the modules in a toxic or dusty
atmosphere.
• Use the modules only in the permitted ambient
conditions (see “16. Technical data” on
page 57).
• Use only the accessories mentioned in Section
15.
• Use the modules only for the intended purpose
described (see “2.1 Intended use” on page 6).
• You may never operate more than one device
simultaneously, otherwise it is impossible to
guarantee compliance with the specified

Safety instructions 9
EN
technical data. For the same reason, you may
not operate the modules whilst oxygen is being
tapped off for external devices.
• The modules are not suitable for hyperbaric
(pressure chamber) use.
• Please monitor that the devices are functioning
perfectly during use, as well – especially if
cylinder pressure is dropping.
• In the event of a device failing, you need to have
an alternative to hand, e.g. for aspiration, the
MANUVAC manual aspiration pump in case the
Suction MODULE or Combi MODULE breaks
down.
Accessories/repairs
• Have repair work performed only by the
manufacturer, WEINMANN Emergency, or
authorized staff.
• If third-party items are used, functional failures
and restricted fitness for use may result.
Biocompatibility requirements may also not be
met. You should be aware that in these cases,
any claim under warranty or liability will be void
if neither the accessories recommended in the
instructions for use nor genuine replacement
parts are used.
• Protect rubber parts from UV light and
prolonged exposure to sunlight, otherwise they
may become brittle and friable.
Oxygen
In combination with flammable substances (grease,
oil, alcohol etc.), highly-compressed oxygen can lead
to spontaneous explosive reactions.
• Keep the devices and all screwed connections
absolutely free of oil and grease.

10 Safety instructions
EN
• It is essential to wash your hands before working
on the oxygen supply.
• Smoking and naked flames are strictly prohibited
in the vicinity of fittings which carry oxygen.
• During assembly and when changing cylinders,
tighten all screwed connections on the oxygen
supply and on the pressure reducer only by
hand. Under no circumstances may you use
tools. Excessive tightening damages the threads
and seals and then leads to leaks.
• Secure oxygen cylinders so they cannot tip over.
If the cylinder falls on the pressure reducer or the
valve, these could be torn off, triggering a
violent explosion.
• Ensure that the respiratory gas is adequately
temperature-controlled. Excessively warm or
cold gas may harm the patient. Please also
observe the permitted ambient conditions (see
“16. Technical data” on page 57).
Important • Always open the cylinder valve slowly to prevent
hammering on the fittings.
• Do not empty cylinders completely, otherwise
damp ambient air may penetrate and lead to
corrosion.
Inhalation
• If you use WEINMANN Emergency inhalation
masks, a dangerous rise in pressure is not
possible.
• However, please ensure that the exhaled
respiratory gas can flow away freely.
Aspiration
• Use the Suction MODULE and the Combi
MODULE only if you are medically trained and

Safety instructions 11
EN
familiar with aspiration technology. Severe
physical injuries can be caused by incorrect use.
• Pay particular attention during aspiration to en-
sure that no injuries are caused to the patient’s
oropharyngeal cavities, e.g. to the mucous
membranes.
• For bronchial aspiration, work under sterile
conditions and use only sterile aspiration
catheters.
Important! • Dispose of fluids such as blood and secretions, as
well as parts contaminated with these fluids, as
per the guidelines in the Federal Health Gazette
entitled “Anforderungen der Hygiene an die
Abfallentsorgung” [Hygiene requirements when
disposing of waste] (published by the Federal
Office of Health and obtainable from Carl
Heymanns Verlag, Cologne).
• Please ensure that the aspirate bottles are always
upright during aspiration, otherwise the ball of
the overflow cutout cannot reliably block the
outlet.
CPAP therapy
• The CPAP MODULE is not licensed for inhalation.
• Use the CPAP MODULE only if you are medically
trained and familiar with CPAP therapy. Severe
physical injuries can be caused by incorrect use.
3.2 Contraindications
Observe the contraindications for the therapies in
question. These may include (examples):
• impaired consciousness
• lung diseases requiring intubation

12 Safety instructions
EN
• use of mask impossible
• undrained pneumothorax
• intracranial hypertension.
3.3 Side effects
If the contraindications are taken into account, no
side effects are likely in use with normal oxygen.
However, observe the side effects mentioned in the
patient information leaflet entitled “Medical
oxygen” in the case of
• newborns
• administration of 100% oxygen
• administration of oxygen under elevated
pressure.

Assembly 13
EN
4. Assembly
If the modules are supplied complete on a LIFE-BASE
or LIFE-BASE Mini carrying platform, they are
operational and you need not perform any further
assembly.
4.1 Assembling the modules
Connecting
1. Release the connection to the oxygen supply
(see “Removing an empty cylinder” on
page 15).
2. Unscrew the cover of the oxygen outlet from the
module.
If you screw the cover back on later, tighten it
just hand-tight to prevent damage to the
housing.
3. Push the protective ring supplied over oxygen
outlet 3. The protective ring prevents dirt
penetrating the housing.
4. Plug the modules together.
The seal is made by the O-ring.

14 Assembly
EN
5. Connect any other modules in exactly the same
way.
No more than 3 modules may be connected,
otherwise it is impossible to guarantee compliance
with the specified technical data.
6. Screw the modules and, if appropriate, the
MEDUMAT onto the assembly plate from the
back as shown in the assembly instructions
provided,
or
screw the modules to a solid wall from the back.
Please note that screws should protrude no
more than 5.5 mm into the modules.
4.2 Connecting oxygen supply
Wash your hands thoroughly before any work on the
oxygen supply. Hydrocarbon compounds (e.g. oil,
greases, alcohols for cleaning, hand cream or
sticking plaster) can lead to explosive reactions if
they come into contact with highly-compressed
oxygen.
Under no circumstances use spanners or other
tools to tighten up the union nuts.

Assembly 15
EN
You should always connect the oxygen supply at the
extreme left-hand module, as oxygen inlet 1of all
modules is equipped with a nonreturn valve.
The nonreturn valve ensures that the oxygen can get
in but cannot get out at this connection.
Oxygen outlet 3has no non-return valve.
For the same reason, the MODULE which allows
connection to an additional external oxygen supply
(in this case an Interface MODULE) should always be
attached the furthest to the left.
Removing an empty cylinder
1. Close the valve on the oxygen cylinder.
2. Switch on a module. This allows any residual
oxygen to escape and the device is
depressurized. The screwed connection may not
be undone until the pressure gauge on the
pressure reducer is displaying “0”.
3. Switch the module off again.
4. Undo the manual screwed connection to the
cylinder.
Connecting a new cylinder
1. Briefly open the valve on the new oxygen cylinder
and close it again. This is intended to blow away
any particles of dust.
Point the valve opening away from your body as
you do this so that you injure neither yourself
nor any other person with any particles which
may fly out!

2. Screw the pressure reducer with the corrugated
union nut to the cylinder valve. Tighten the
union nut hand-tight.
3. Screw the pressure tube with the G 3/8 union
nut to the pressure reducer outlet.
4. Screw the other end of the pressure tube to
oxygen inlet 1of the module.
4.3 External oxygen connection
In addition to oxygen inlet 1, you can use external
oxygen connection 8to tap off or feed in oxygen.
Tapping off oxygen
You may not operate a module at the same time as
tapping off oxygen, otherwise the specified
technical data will not be maintained.
Feeding in oxygen
You can use the external oxygen feed for example to
allow continued working with the modules when
the oxygen cylinder is being changed.
Due to the nonreturn valves in oxygen inlet 1,
oxygen should always be fed in at the module fitted
on the extreme left.

4.4 Assembling breathing station
Disposable inhalation mask and nasal cannula
The disposable nasal cannula and inhalation masks
with or without economy bag are made of
transparent plastic. For hygiene reasons, they may
only be used for one patient.
1. If necessary, screw union nut 7supplied onto the
corresponding threaded connection of the
Oxygen MODULE or the Combi MODULE.
2. When the module is used, plug the tube onto
the union nut.
4.5 Assembling the bubble humidifier
1. Unscrew the tank from the top part of the
bubble humidifier.

18 Assembly
EN
2. Screw the top part of the bubble humidifier onto
the corresponding threaded connection of the
Oxygen MODULE or the Combi MODULE by
hand.
3. Fill the bottom part up to the mark with distilled
water (aqua dest.) and screw the tank back on.
4. Push the tube for the breathing station onto the
outlet stub of the bubble humidifier.
4.6 Assembling the OMNIVAC
secretion aspiration system
The OMNIVAC secretion aspiration system is
required for aspiration using the Suction MODULE or
the Combi MODULE.
1. Screw the holder for the secretion aspirate
bottles to a suitable point.

Assembly 19
EN
2. Put both aspirate bottles in the holder.
3. Connect the bottles and the module with the
appropriate tubes. Ensure that the bottle with
the overflow cutout is connected to the module
first.
We recommend fitting a hydrophobic bacteria filter
WM 22291 for the exhaust air to prevent secretion
and bacteria penetrating the module. Filter
WM 22291 is obtainable as an accessory, individually
or in sets. It is a disposable item and must be replaced
after every aspiration operation.
4. Take the vacuum tube off the module.
5. Cut a piece about 6 cm long off the vacuum
tube.
6. Put this short piece of tube onto the side of the
filter marked with “TO PUMP”.
7. Plug the other end of the short piece of tube
onto the vacuum connection of the module.
8. Put the free end of the vacuum tube on the filter.

EN
4.7 Assembling the CPAP valve
1. Connect the CPAP valve to the CPAP module
using the connecting tubes.
Ensure that the tubes are guided cleanly so that
they do not impede one another.
2. Perform a function check (see “12.6 Checking
oxygen flow” on page 47).
