EN
1. Description
1.1 Uses
OXYWAY Click is a click dial flowmeter for dispensing
medical oxygen supplied at a system pressure of 4.5 bar by
central gas systems. It is used to increase the proportion of
oxygen in the inhaled air (oxygen inhalation).
1.2 Function
OXYWAY Click
Flow: Dispensing volume,
stated in litres per minute.
During operation, the oxygen supplied by the central gas sys-
tem at a pressure of 4.5 bar passes through the inlet connector
1into the body 2of the OXYWAY Click.
The dial head 3contains an orifice disk with orifices of dif-
ferent diameters which are lined up with the oxygen outlet
4by means of a click dial system. You can set the following
flow rates: 1, 2, 3, 4, 5, 6, 9, 12, 15 l/min.
Functional description of oxygen
inhalation
You can use the OXYWAY Click for oxygen inhalation.
Oxygen inhalation only makes sense for patients with
spontaneous breathing.
12
3
4

6Description
EN
If breathing stops, oxygen inhalation is by no means suffi-
cient: in such cases artificial respiration is necessary. The
oxygen pressure during inhalation is not sufficient to over-
come the airway resistance, which means that not enough
oxygen would enter the lungs.
The oxygen is fed to the patient through an inhalation
mask or nasal canula.
You can use an inhalation tube connected to the
OXYWAY Click to attach a breathing bag in order to en-
sure respiration of the patient with an elevated oxygen
concentration.
To prevent drying of the mucous membranes during pro-
longed oxygen inhalation, you can attach a bubble humid-
ifier (see “3.3 Attaching the bubble humidifier” on
page 11).

2.2 Safety rules
For your own safety, the safety of your patients, and to
comply with the requirements of EU Directive 93/42/EEC,
please observe the following points.
Oxygen
Spontaneous explosive reactions can occur if compressed
oxygen comes into contact with flammable substances
(fat, oil, alcohol etc.):
• Keep the equipment and all screw connections abso-
lutely free from oil and grease.
• Never place OXYWAY Click in a disinfectant solution
or other cleaning solution. The patient could inhale
any residual liquid. This could result in injury to the air-
ways. A clean cloth, possibly moistened with clean hot
water, is sufficient for cleaning.
• Always wash your hands before starting to work on
the oxygen supply.
• Smoking and open flames are strictly prohibited in the
vicinity of all fittings containing or transporting
oxygen.
Inhalation
If breathing stops, oxygen inhalation is by no means suffi-
cient: in such cases artificial respiration is necessary. The
oxygen pressure during inhalation is not sufficient to over-
come the airway resistance, which means that not enough
oxygen would enter the lungs.
If you use Weinmann inhalation masks, it is not possible
for the pressure to rise to dangerous levels. You should
however make sure that the exhaled air can escape freely
so that it is not breathed in again.
Attention!

Operating the appliance
• Please observe these operating instructions. They are
an integral part of the OXYWAY Click and must be
kept available for reference at all times.
• Before starting to work with OXYWAY Click, you
must understand how to operate it.
• A back-up ventilator should always be available in
case of technical failure.
• To prevent infection or bacterial contamination,
please observe Chapter “4. Hygienic preparation” on
page 12.
• Use the OXYWAY Click for the described purpose
only (see “1.1 Uses” on page 5).
Accessories/Repairs
• Always have inspections or repairs carried out by the
manufacturer (Weinmann) or trained expert person-
nel.
• If third-party items are used, functional failures may
occur and fitness for use may be restricted. Biocom-
patibility requirements may also not be met. Please
note that in such cases, any claim under warranty and
liability will be voided if neither the accessories nor
genuine replacement parts recommended in the in-
structions for use are used.
• Protect rubber parts from UV light and prolonged
direct sunlight, as these can make them brittle and
friable.

10 Operation
EN
3. Operation
3.1 Preparing for use
1. Make sure that the dial head of the flowmeter is in po-
sition “0”.
2. Connect the OXYWAY Click to the central gas system.
This is done by pushing the inlet connector of the
OXYWAY Click into the socket of the central gas sys-
tem until you hear it snap into place.
3. Connect the inhalation accessories to the OXYWAY
Click.
4. Use the dial head to set the desired flow.
5. The OXYWAY Click is now ready for use.
3.2 After use
1. Set the dial head to “0”. This is necessary to prevent
pressure hammer when the oxygen supply is opened
again later.
Important
OXYWAY Click is not a shutoff valve! Small amounts
of oxygen can still escape even when it is completely
closed.
2. If the OXYWAY Click is no longer needed here,
remove it from the supply socket.

3.3 Attaching the bubble humidifier
1. Unscrew the container from the top of the bubble
humidifier.
2. Unscrew the union nut from the oxygen outlet and
remove the connector.
3. Screw the top part of the bubble humidifier by hand
onto the threaded connection of the OXYWAY Click.
4. Fill the container up to the mark with distilled water
(aqua dest.) and screw the container on again.
5. Push the tube of the breathing unit onto the outlet
connection stub of the bubble humidifier.

3.4 Attaching the nasal canula
The nasal canula is made of transparent plastic. For
hygiene reasons it must be used for one patient only.
1. If necessary, screw the connector and union nut onto
the threaded connection of the OXYWAY Click.
2. Push the tube of the nasal canula onto the connnector
of the OXYWAY Click.
4. Hygienic preparation
This product may contain disposable items. Dispos-
able items are intended to be used only once. So use these
items only once and do not reprocess them. Reprocessing
disposable items may impair the functionality and safety of
the product and lead to unforeseeable reactions as a result
of ageing, embrittlement, wear, thermal load, the effects
of chemical processes, etc.
If you need to clean the outside of the device, always use
a clean cloth. The cloth may be dry or moistened with
clean water.
In exceptional cases where wiping with disinfectant is es-
sential, take special care to ensure that no liquid enters the
OXYWAY Click. Otherwise there is a risk that residual dis-
infectant may enter the patient's airways and cause injury.
We recommend you to use the disinfectant TERRALIN®.
You are recommended to wear suitable gloves (e.g.
household or disposable gloves) during disinfection
procedures.

Functional check 13
EN
5. Functional check
Perform a functional check every 6 months. To do so,
proceed as follows:
1. Make a visual check on the OXYWAY Click for
mechanical damage.
2. Make sure that the dial head of the flowmeters is in
position “0”.
3. Connect the flowmeter to the central gas system.
4. Check that the flowmeter is firmly engaged in the
socket of the central gas system.
5. Now use the dial head to set all index positions in suc-
cession, and check at the oxygen outlet whether the
flow increases in line with the setting.
6. Reset the click dial head to “0”.
Important
OXYWAY Click is not a shutoff valve! Small amounts
of oxygen can still escape even when it is completely
closed.
7. You can now start using the OXYWAY Click.
If the functional check reveals any faults, do not use the
OXYWAY Click.
