1 Introduction
1.1 Model
JOYCEeasy, JOYCEeasy Full Face
1.2 Intended use
JOYCEeasy nasal masks and JOYCEeasy Full
Face masks are used for treating sleep
apnea and for non-invasive and non-life-
sustaining ventilation of patients with
respiratory insufficiency. It serves as a
connecting element between the patient
and the therapy device.
1.3 Contraindications
In the case that any of the following
symptoms are present the mask may not be
used, or only with particular caution:
erosions and ulcerations, skin allergies, flush
of the facial skin, pressure marks on the
face, claustrophobia, anxiety, deformities of
the face or nasopharynx, intake of
medication which may induce vomiting, the
necessity for immediate intubation. Please
also observe the contraindications in the
instructions for use of your therapy device.
1.4 Side effects
Nasal congestion, dry nose, morning
xerostomia (dry mouth), feeling of pressure
in the sinuses, irritated conjunctiva, skin
rashes, pressure marks in the face, irritating
noises when breathing.
1.5 Structure and
components
The mask consists of a headgear, forehead
cushion, forehead support, lock, retaining
ring, elbow, plug for pressure measurement
port, pressure measurement port, rotating
sleeve, mask body, headgear clip, mask
cushion and an anti-asphyxia valve (on full
face masks only). The product is non-sterile
and reusable.
2 Safety
Please read these instructions carefully. They
are a constituent part of the mask and must
be available at all times. In accordance with
Directive 93/42/EEC, observe the points
below.
2.1 Safety information
Risk of injury from the supply of
oxygen!
Oxygen can deposit on clothing, bed linen
and hair. In conjunction with smoking,
naked flames or electrical equipment, it can
cause fires and explosions.
Do not smoke.
Avoid naked flames.
Do not use electrically conductive tubes
(exception: breathing tubes which can
be heated electrically).
Risk of injury from oxygen therapy!
Oxygen therapies can lead to side effects in
case of incorrect use or dosage.
Only administer oxygen as prescribed by
a physician.

6 EN JOYCEeasy
WM 67630g 04/2020
Follow the instructions for use of the
oxygen system and therapy device.
Risk of injury from re-inhaling CO2!
If the mask is used incorrectly, CO2 may be
re-inhaled.
Do not close the openings of the mask.
Only apply the mask for a prolonged
period if the therapy device is running.
Only use the mask within the quoted
therapy pressure range.
Do not use the mask on patients who
cannot take it off themselves.
Monitor patients with obstructive and
restrictive lung diseases individually
when using JOYCEeasy masks.
Risk of injury from slipping of the
mask!
If the mask slips or falls off, the therapy is
ineffective.
Monitor patients with restricted
spontaneous respiration.
Activate low pressure/leakage alarms on
the therapy device.
Monitor patients with obstructive and
restrictive lung diseases individually.
Patient endangerment through application
of mask during anesthesia!
When the nasal mask is used during
anesthesia, the anesthetic gas supplied can
escape through the mouth and endanger
the patient.
Do not use nasal mask during
anesthesia.
2.2 General information
• Use of third-party products may lead to
functional failures and restricted fitness
for purpose. Biocompatibility may also
be compromised. Please note that in
these cases, any claim under warranty
and liability will be void if neither the
accessories nor original replacement
parts recommended in the instructions
are used.
• To prevent infection, bacterial
contamination or functional
impairments, follow the instructions in
the section “Hygiene preparation” (see
"5 Hygiene preparation", page9).

13 Anti-asphyxia valve (on full-face masks only,
see figure F)
3.2 Compatible devices
The mask can be used with all therapy
devices which are not for life-sustaining
treatment of patients with sleep apnea or
ventilatory insufficiency.
With many combinations of device, the
actual pressure in the mask will not
correspond to the prescribed therapy
pressure, even if the therapy device is
displaying the correct pressure. Have the
combination of devices adjusted by a
physician or specialist dealer so that the
actual pressure in the mask corresponds to
therapy pressure.
Quick-release cord (optional)
You can use a quick-release cord (accessory)
to open the headgear in emergency
situations (e.g. vomiting).
The quick-release cord consists of a special
clip with a cord which you can fit to the
mask instead of one of the bottom
headgear clips.
In an emergency, simply pull the quick-
release cord. The special clip will detach
itself from the mask. The headgear is now
open and the mask can be removed
(figure G).
3.3 Exhalation system
The mask has an integrated exhalation
system. The retaining ring and mask body
are shaped in such a way that a gap forms
between these parts. The exhaled air can
escape through this gap (figure A2).
3.4 Anti-asphyxia valve
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
breathing CO2 back in and thus also the risk
of asphyxia. Inside the anti-asphyxia valve is
a membrane which can adopt one of two
positions:
• as long as the therapy device is in
operation, the air flow forces the
membrane against the opening to the
atmosphere and seals it completely. The
patient breathes through the therapy
device.
Risk of asphyxia if anti-asphyxia valve
not working properly!
Residues may block the mask and
jeopardize the success of therapy.
Check before each use that the anti-
asphyxia valve is working properly.
Clean contact surfaces between the
elbow and the rotating sleeve
thoroughly.

8 EN JOYCEeasy
WM 67630g 04/2020
• if the therapy device fails or if the device
is not connected, the membrane is in the
rest position, in other words the
opening to the atmosphere is free. The
patient breathes ambient air through
this opening.
3.5 Pressure measurement
port
The mask has a connection 8 which can be
used for measuring pressure or supplying
oxygen. If you are not using the pressure
measurement port, close it with the plug 7
to reach therapy pressure.
4 Operation

the lock 4 bit by bit as necessary (figure
C1).
3. Applying the mask (see "4.1 Applying
the mask", page8).
4. Adjust headgear 1 with the aid of the
hook-and-loop fasteners so that the

loop fastener, pull on the ends of the
headgear with both hands and close the
fastener again (figure C3).

WM 67630g 04/2020
JOYCEeasy EN 9
8. Take rotating sleeve 9 off elbow 6
(figure D7).

damage or trap the membrane on the
inside of the anti-asphyxia valve.
5 Hygiene preparation
•This product may contain disposable
items. Disposable items are
intended for single use. Therefore,
use these items only once and do not
reprocess them. Reprocessing
disposable items may impair
functionality and safety of the product
and lead to unforeseeable reactions due
to ageing, embrittlement, wear, thermal
stress, the effects of chemical processes
etc.
5.1 Cleaning the mask
1. Dismantle the mask (see "4.4
Dismantling the mask", page8).
You can tell whether the headgear is
correctly attached by the hook-and-loop
tabs. The hook-and-loop tabs on the
forehead have the same color as the
inside of the head bands.
Risk of injury from inadequate cleaning!
Residues may congest the mask, impair the
integrated exhalation system and
jeopardize therapy success.
For patients with a compromised
immune system or particular
background of illness, disinfect mask
components daily following consultation
with the physician.
Thoroughly clean the contact surfaces
between the elbow and the rotating
sleeve.

3.2 仪器适配
可以将此呼吸面罩与所有治疗仪器结合使
用，这些治疗仪器均不用于患有睡眠呼吸
暂停综合症和呼吸功能不全的患者的生命
维持治疗。
在有些仪器组合上，其呼吸面罩中的实际
气压与规定的治疗气压不一致，即使治疗
仪器上显示的是正确的气压。请医师或特
约经销商对仪器组合进行调节，以使面罩
中的实际气压与治疗气压一致。
拉绳 （选用）
为了在紧急情况 （例如呕吐）下打开头
带，您可以使用拉绳 （配件）。
拉绳由一个带线的专用夹组成。该夹子可
以代替其中一个下带夹安装在鼻罩上。
在紧急情况下拉动拉绳，专用夹就从鼻罩
上松开。头带现在处于打开状态，然后就
可以取下鼻罩了 （插图 G）。
3.3 呼气系统
面罩配有一个内置呼气系统。安全环和面
罩壳的造型使在部件之间产生一个间隙，
呼出的气体可以通过这一间隙泄漏 （插图
A2）。

3.4急救呼气阀
急救呼气阀的安全功能
急救呼气阀配有一个大气开口，患者可以
在治疗仪器发生故障的情况下吸入室内空
气。这明显减少了二氧化碳重复吸入的危
险和因此导致的窒息危险。急救呼气阀
内，有一个可以设置两个位置的膜片：
•只要治疗仪器工作，膜片就在大气开口
前被气流压迫并使其完全关闭。患者可
以通过治疗仪器呼吸。
•在治疗仪器发生故障或设备未连接时，
膜片位于原始位置，即大气开口打开。
患者可以通过此开口呼吸室内空气。
3.5 测压接口
呼吸面罩配备 1 个接头 8，以便对压力进
行测量或导入氧气。当不使用测压接口
时7，请用堵头将其封闭，以达到治疗气
压。
