Vented Variants - Weinmann JOYCE Full Face vented 40 hPa Instructions For Use Manual

2. Place the headgear over your head and
hook the headgear clip back onto the
strap.
3. Position the mask on your face as shown
in Figure B.
Note:
If using JOYCE Full Face
that the chin strap is correctly located, i.e.
that it surrounds your chin completely.
Otherwise the mask may slip when you
move.
4. Adjust the headgear with the aid of the
hook-and-loop closures so that the mask
seals on the face but is not too tight.
WEINMANNstrap only:
The WEINMANNstrap headgear pro-
vides the following additional options
(see also "Overview" on the enclosed
leaflet):
– hook-and-loop closures on both sides.
– hook-and-loop closure on top of the head:
release the hook-and-loop closure, pull
gently on the ends of the headgear with
both hands and push the hook-and-loop
closure back on.
You can tell whether the headgear is
correctly attached by the hook-and-
loop tabs. The hook-and-loop tabs on
the forehead are the same color as the
inside of the headgear.
HEADstrap only:
The HEADstrap headgear provides the
following options for you to do this:
– coarse adjustments: slot of the headgear.
– fine adjustments: four hook-and-loop
straps."
5. If necessary, re-adjust the forehead
support.
3.3 Exhaled air system (Fig. H)

vented variants

vented variants (all mask components are
transparent) have an integrated exhaled
air system: the retaining ring and mask
plus
vented, ensure
frame are shaped in such a way that a gap is
formed between these parts. Through this
gap the exhaled air can escape. The special
geometry of the parts guarantees that when
putting on the retaining ring the gap cannot
be closed. Do not connect an external
exhaled air system, otherwise the therapy
pressure will not be reached.
non vented variants
Warning!
The non vented variants (retaining ring,
elbow and rotating sleeve in blue) do not
have their own exhalation system! They
may only be used in combination with
therapy devices which have an active
exhalation valve! If the therapy device fails,
there is otherwise the risk of re-inhalation of
CO and suffocation.
2
The non vented variants may never be used
in combination with an external exhalation
system (such as Silentflow2, for example),
otherwise the safety function is not
guaranteed in the event of device failure. See
also the instructions for use for your therapy
device.
3.4 Anti-asphyxia valve (Fig. G)
Warning!
Only the vented variants are equipped
with an anti-asphyxia valve. Ensure that this
valve is working correctly before every use
(see "5. Functional check" on page 21),
otherwise there is a risk of suffocation!
Safety function of the anti-asphyxia
valve
The anti-asphyxia valve has an opening to the
atmosphere through which the patient can
inhale ambient air if the therapy device fails.
This significantly reduces the risk of re-
inhaling CO and thus also the risk of
2
suffocation.
Inside the valve is a membrane which can
adopt either of two positions:
• As long as the therapy device is in opera-
tion, the membrane is pressed against the
opening to the atmosphere by the flow,
