The invention relates to a medical assembly composed of an emergency respirator and
of its support device, that is to say a mount which is designed to be fixed to a wall, for
example a wall of a hospital building or a wall of an emergency vehicle such as an ambulance,
etc., comprising an electrical connection system which permits recharging of the batteries of
the respirator when the latter is positioned and locked on the mount.
Devices or apparatuses for artificial respiration, referred to as "respirators" in the
context of the present invention, are widely used in hospital buildings or in mobile emergency
units, such as ambulances, etc., in order to assist patients suffering from breathing difficulties.
These respirators are conventionally disposed on a wall support device, that is to say
on a mount fixed to a wall, when they are not in use, and they are removed from the wall
support device by medical personnel when they are to be used.
The respirators are equipped with electric batteries to ensure their electrical autonomy.
These batteries have to be recharged more or less frequently depending on the intensity of use
of the respirator.
At the present time, wall supports for fixing medical respirators are available in two
types, namely those which have no system for recharging the batteries of the respirator and
which withstand an acceleration of log, which is the acceleration force that the
respiratorlmount has to withstand without breaking, so as to avoid a situation where they
become projectiles and endanger the safety of the persons present in the mobile emergency
units, such as ambulances; and, fbrthermore, those which do have a system for recharging the
batteries of the respirator, but which only withstand a load of 3g.
Thus, mention may be made of the following documents which propose such
respirators: FR-A-2906 149, DE-A- 1020 100 1264 1, DE-A- 102008064480 and DE-A-
10200803965 1.
However, these assemblies composed of a wall fixing device and of an associated
respirator often have a complex architecture, which does not always permit easy and quick
fixing of the respirator on the support andlor quick or easy electrical connection thereof.
Moreover, the document FR-A-2906149 proposes a mobile assembly for patient
treatment which is composed of a respiratory assistance system and of a support mount that
can be connected to an interface on the patient side and is supplied with gas from an oxygen
bottle and with current from an energy accumulator. This device makes it possible to quickly
determine the COz concentration of the patient's blood and to supply the patient with 0 2 when
this COz concentration is too high. The device can comprise a fixing system by which it can be
fixed to a wall, especially in an emergency vehicle. The fixing is achieved by means of a
locking shaft being put in position, tilted and snap-fitted into a support plate. This device
withstands loads of 3g, or even 6g or more.
Therefore, the problem that arises is that of making available an improved assembly
composed of a wall fixing device or mount and of an associated respirator, which comprises a
battery-recharging system and can advantageously withstand an acceleration of log in 3
directions (x, y, z), allowing the user to fix the respirator rigidly, quickly and easily to the
support device, irrespective of whether said support device is fixed on a wall of a hospital
building or on a wall of an emergency vehicle or the like, such as an ambulance, a fire engine,
etc., directly or by way of a rail.
The object of the present invention is therefore to make available an assembly
composed of a support device or mount and of an associated respirator, which assembly not
only allows the respirator to be fixed easily and quickly on its support but also permits
simultaneous electrical connection of the respirator to a current source supplying the mount.
The solution is therefore a respiratorlmount assembly comprising a respirator, that is to
say a device or apparatus for artificial respiration, and a mount, that is to say a wall support
device, which is able and designed to receive and carry the respirator, said mount comprising a
fixing system for fixing it directly or indirectly to a wall, characterized in that it additionally
has:
- a hooking system allowing the respirator to be placed in a coupling position on the
mount,
- a locking system allowing the respirator to be immobilized in a locking position on
the mount, subsequent to the coupling position, the locking position being distinct from the
coupling position, the locking system comprising first locking means carried by the respirator,
and second locking means which are carried by the mount and which are able and designed to
cooperate with the first locking means, in such a way as to allow the respirator to be fixed
rigidly on the mount in the locking position, and
- an electrical connection system making it possible to ensure an electrical connection
between the respirator and.the mount, subsequent to the coupling position and simultaneous or
almost simultaneous to the locking position, the locking position being distinct from the
coupling position, and
- an electrical connection system making it possible to ensure an electrical connection
between the respirator and the mount, subsequent to the coupling position and simultaneous or
almost simultaneous to the locking position,
characterized in that the first locking means carried by the respirator comprise an
abutment, and the second locking means carried by the mount comprise a pivoting detent, said
detent cooperating with said abutment in order to hold the respirator securely on the mount in
the locking position, the detent being carried by a detent support and being actuated by a
spring which bears normally on the front part of the detent in order to ensure said secure hold
of the respirator on the mount in said locking position.
Depending on the particular case, the respirator/mount assembly according to the
present invention can comprise one or more of the following technical features:

is in the locking position;
- it additionally comprises release means cooperating with the second locking means in
such a way as to permit disengagement and release of said first locking means, and to
additionally permit, at the same time or almost at the same time, a disconnection of said first
and second electrical contactor means from each other;
- when the respirator is in the coupling position on the mount, said respirator is
movable by pivoting or tilting with respect to the mount;
- the first hooking means of the respirator comprise a first seat, and the second hooking
means of the mount comprise a projecting element which is able and designed to engage, at

- when the user actuates the lever, said lever acts on the detent in such a way as to
disengage the latter from the abutment;

- the front part or head of the detent has a rounded shape in order to permit easy and
quick mechanical connection to the respirator, simply by placing them in contact and then
pressing manually on the respirator provided with the fixing panel.
The invention further relates to a respirator of an assembly according to the invention
comprising a support panel fixed to the rear face of the respirator, and also a mount of an
assembly according to the invention.
In other words, the respiratorlwall mount assembly according to the present invention
is based on a combination of elements and means comprising a hooking system which permits
quick and easy mechanical coupling of the respirator to its wall support, that is to say the
mount, a mechanical connection system which is used to lock the respirator, that is to say keep
the respirator immobilized on the mount, up to a maximum acceleration of log, and a system
for quick electrical connection by which the respirator can be electrically connected to the
mount, which is itself supplied with electric current fiom the mains, so as to either ensure the
functioning of the apparatus (without battery) or to be able to recharge the batteries of the
respirator once the latter has been locked on the mount.

Figures 5 and 6 are schematic representations of an embodiment of a respiratorlmount
assembly according to the present invention comprising a respirator 10, that is to say a device
or apparatus for artificial respiration, and a wall mount 20 serving as a support device by being
able and designed to receive and carry the respirator 10.
The respirator 10 comprises a front face 10a with, conventionally, one or more control
elements, such as buttons, keys, cursors, etc., one or more displays, such as screens, indicators,
etc.
Moreover, the mount 20, serving as a wall support device as shown in detail in Figures
1, 2 and 4, comprises a fixing system 3 1 for fixing it to a wall, for example to a wall 100 of a
hospital building, as is shown schematically in Figure 4.
Here, the mount 20 is fixed to a wall 100 via a supporting rail 30, to which the fixing
system 31 is attached; for example the fixing system 31 may comprise two jaws and a
clamping screw. Any other appropriate fixing system 3 1 is also suitable. The fixing system 3 1
is carried by the rear face or framework 3 of the support 20, as is illustrated in Figures 2 and 4.
The respiratorlmount assembly according to the invention additionally comprises a
hooking system 1, 1 1,2,2 1 permitting an easy and quick coupling position of the respirator 10
on the mount 20, by simply hooking the respirator 10 onto the mount 20, as is illustrated in
Figures 5 to 7.
More precisely, the hooking system 1, 1 1, 2, 2 1 comprises first hooking means 1, 1 1
carried by the respirator 10, and second hooking means 2,21 which are carried by the support
device or mount 20 and which are able and designed to cooperate with said first hooking
means 1, 11 in such a way as to permit easy and quick positioning and to hook the respirator
10 onto the mount 20.
I
first seat or recess 11, in particular an opening or cutout, formed in a rear metal plate or fixing
panel 1 which is fixed to the rear face lob of the respirator, for example by screwing with the
aid of in this case four screws arranged in a VESA type geometry, as is shown in detail in
5 Figure 3.
The rear fixing panel 1 thus serves as an interface between the respirator 10 and the
wall piece, that is to say the support device 20. It is fixed permanently on the respirator 10.
It will be noted that the first seat or recess 11 can also be formed directly in the wall of
the rear face lob of the respirator 10 and that, in this other embodiment (not shown), it is
10 possible to dispense with the fixing panel 1.
Moreover, the second hooking means 2,21 carried by the support device 20 comprise,
for their part, at least one hooking tab 21, that is to say a projecting element that is configured
and dimensioned to permit its insertion into the seat 1 1 of the respirator 10.
This hooking tab 21 can be advantageously formed by a projecting portion of a plate
15 forming the front face or front framework 2 of the mount 20, as is illustrated in Figure 2.
Indeed, as is illustrated in Figures 5 to 7, a user positions the respirator 10 on the wall mount
20 by simply inserting the projecting hooking tab 21 into the seat or opening 11 of the mount I 20. 1 The respirator 10 is then in a coupling position, that is to say it is connected non-
I
20 rigidly to the support 20 by being held thereon simply by the cooperation between the hooking
I tab 2 1 and the seat 1 1. In this coupling position, the respirator 10 can be withdrawn from the
wall support 20 simply by removing the hooking tab 2 1 from its seat 1 1.
In other words, the first hooking means 1, 1 1, comprising the seat 1 1 and carried by the
I
rear plate 1 of the respirator 10, cooperate with the second hooking means 2, 2 1, comprising
25 the hooking tab 21 and carried by the front face 2 of the support device or mount 20, in such
as way as to ensure correct positioning and hooking of the respirator 10 on the wall mount 20.
However, in this position, called the coupling position, the respirator 10 is not held rigidly on
the mount 20.
To make it easier to place the respirator 10 in the coupling position on the mount 20, a
30 coding system 70, 71 is advantageously provided on the respirator 10 and on the mount 20.
I For example, it is possible to provide a projecting element 70 which is carried by the front face
or framework 2 of the mount 20, as is illustrated in Figures 1,2 and 4, and which engages in a
third seat or recess 71, which has an at least partially complementary shape and is formed in
the rear plate or panel 1 of the ventilator 10, as is illustrated in Figures 3 and 5 in particular.
35 Once the ventilator 10 has been coupled to the mount 20 by inserting the hooking tab
21 into the first seat 11 of the panel 1, the projecting element 70 carried by the front
framework 2 of the mount 20 makes it possible to ensure correct positioning and alignment of
the respirator 10 on the mount 20, by engaging in the third seat 7 1, and centring itself therein,
when the user tilts the ventilator 10 angularly from the coupling position to the locking
position by exerting a bearing force (arrow in Figure 7) on the lower part of the respirator 10,
as is shown schematically in Figure 7.
Thereafter, in order to then immobilize the respirator 10 in a locking position on the
mount 20, that is to say in order to join them rigidly to each other, a locking system 1, 12, 13,
40-45 is also provided. This locking system 1, 12, 13, 40-45 makes it possible to ensure a
good mechanical connection of the respiratorlwall mount assembly, that is to say ensures that
the respirator 10 is maintained in a fixed position and rigidly on the mount 20, afier it has been
placed in the coupling position.
The locking position is therefore a position of the respirator 10 on the support 20 that is
distinct from the coupling position since, in the locking position, the respirator 10 is
maintained firmly on the wall mount 20 and cannot be removed therefrom without prior
actuation of release means, as is described in detail below.
Schematically, the locking position is a position angularly offset with respect to the
coupling position, and one therefore proceeds from said coupling position to the locking
position by executing a slight pivoting or tilting movement of the respirator 10 about the axis
AA (cf. Figures 5 and 6) which forms upon insertion of the hooking tab 2 1 within the seat 1 1.
More precisely, the locking system 1, 12, 13, 40-45, which ensures that the respirator
10 is maintained in a fixed position and rigidly on the mount 20, comprises a set of mechanical
components or elements that permit a mechanical connection of the respirator 10, provided
with the fixing panel 1, on the wall support 20.
This set of mechanical components or elements, which forms the locking system 1, 12,
13, 40-45, comprises first locking means 1, 12, 13 which are carried by the respirator 10 and
cooperate with second locking means 40-45 which are carried by the mount 20, in such a way
as to guarantee that the respirator 10 is fixed and held rigidly in the locking position on the
support device or mount 20.
The second locking means 40-45, carried by the mount 20, advantageously comprise a
pivoting detent 40 carrived by a detent support 42 and actuated by a spring 41 provided with a
spring head 43, as is shown in detail in Figure 8. The detent 40 pivots about its detent axis BB,
carried by the detent support 42, while at the same time being maintained there. Suitable
dimensioning of the spring 41 permits a resistance to a traction force of log applied to the
respirator.
The detent spring 41 bears normally on the front part 45 of the detent 40, that is to say
the head of the detent 40, by way of the spring head 43, in order to keep the detent in the
locked or locking position. The front part or head 45 of the detent 40 preferably has a rounded
shape in order to permit easy and quick mechanical connection to the respirator 10, simply by
placing them in contact and then pressing manually on the respirator 10 provided with the
fixing panel 1.
In fact, the fixing panel 1 situated on the rear face lob of the respirator 10 comprises
first locking means cooperating with the second locking means of the mount 20, i.e. in
particular with the detent 40 and the detent spring 41.
More precisely, the first locking means of the respirator 10 comprise an abutment 13
which cooperates with the claw 44 carried by the head or front part 45 of the detent 40 in order
to ensure that the respirator 10 is held rigidly on the wall mount 20 in the locking position, as
is illustrated in Figures 8 and 9.
As is shown in Figure 3, an abutment 13 can be formed by a part of the wall of the rear
panel 1 of the respirator 10. In particular, the rear panel 1 here comprises a second seat or
recess 12 which is dimensioned and configured to receive in particular the detent 40, as is
shown in Figure 9, where a part of the wall of said rear panel 1 situated at the immediate
periphery of the recess 12 constitutes said abutment 13 on which the claw 44 of the detent 40
abuts when the respirator 10 is in the locking position (Figures 6 and 9).
Moreover, the respiratorlmount assembly according to the invention also comprises an
electrical connection system 50, 51 by which it is possible to ensure an electrical connection
between the respirator 10 and the mount 20, subsequent to the coupling position and
simultaneous or almost simultaneous to the locking position, by tilting or pivoting the
respirator 10 in the direction of the wall mount 20, as is illustrated in Figures 5 to 7 in
particular.
The electrical connection system 50, 51 comprises first electrical contactor means 50
which are carried by the respirator 10 and cooperate with second electrical contactor means 5 1
carried by the mount 20, in such a way as to establish an electrical connection between the
respirator 10 and the mount 20 when the respirator 10 is in the locking position.
In other words, when the respirator 10 is tilted by a user from the coupling position to
the locking position, the first and second electrical contactor means 50, 51 are connected to
each other in order to obtain electrical continuity between the respirator 10 and the mount 20
supplied with electrical current from the mains, and in order thereby to charge or recharge
electric batteries of the respirator 10.
The electrical connection system 50, 51 preferably comprises at least two electrical
contacts and one or more electrical cables permitting the electrical interface between the
power supply and the respirator 10.
As is shown in detail in Figure 10, the electrical connection system 50, 51 comprises a
plug support, two electrical contacts 52 of the male type on a spring, compensating for the
possible divergences of positioning, which are connected by a strand 55 to the mount 20,
which is itself connected to a current supply, for example converting the mains current , i.e.
5 110 V or 220-230 V (alternating) to 12-24 V (direct). It additionally comprises one or more
contact covers 53 and one or more ejection springs 54.
The one or more contact covers 53 allow electrical contacts 52 to be protected from the
environment and thus protect the user from possible danger from electricity. With the one or
more ejection springs 54, they also permit the disengagement of the respirator 10 at the time of
10 its mechanical disconnection from the mount 20.
On the respirator 10, the electrical contacts 50 are of the female type and receive the
two male electrical contacts 52 of the mount 20, which are engaged therein by mechanical
insertion.
The power supply 8, connected to the mains, is joined (at 9) to the wall mount 20 and
15 to the electrical contacts of the second electrical contactor means 51 carried by the mount 20.
Correct electrical connection is signalled by an indicator light placed on the front face of the
I power supply 8.
1 The power supply 8 can be removed from the support device or mount using a quick-
I
I coupling system. Moreover, the electrical power supply 8 can be integrated permanently in the
I
I 20 rear framework 3.
The respirator 10 for its part has one or more electric batteries which ensure that the
power needed for it to operate is supplied when it is disconnected from the mount 20, for
I
example ensuring a stand-alone operation of at least 1 to 2 hours, or even longer.
The respirator 10 also has, on its front face 10a, an indicator light that signals the
25 correct charging or recharging of the batteries. This information can be provided on the
support device or mount 20 by an indicator light.
The assembly according to the invention also comprises release means 60, 6
cooperating with the second locking means 40-45 in such a way as to permit disengagement
and release of said first locking means 1, 12, 13, and to additionally permit, at the same time
30 or almost at the same time, the disconnection of said first and second electrical contactor
means 50,5 1 from each other.
Advantageously, the release means 60, 6 comprise a lever or handle 6 which can be
actuated by the operator and which, afier actuation, moves between at least a first position,
called the locking position, in which it does not act on the second locking means 40-45 and in
35 which the respirator 10 is in the locking position, and at least a second position, called the
release position, in which it interacts with the second locking means 40-45 in order to release
the respirator 10 such that the latter can be removed from the mount 20. The contact cover 53
then returns to its initial position in order to fulfil its safety function.
Manual actuation of the handle or lever 6 by the user causes an unlocking of the
mechanical and electrical connection systems and allows the user to remove the respirator 10
5 from its wall support 20.
For the unlocking, the handle 6 actuates the detent 40 by way of a welded sleeve 61.
The detent 40 pivots on the axis CC in yokes 62. It is provided with a return spring 63, which
is dimensioned to guarantee the locked position of the handle 6 in the event of an acceleration
of log, and which is fixed on the detent support 42 by a pin.
10 Finally, a ventilator/mount assembly according to the present invention is particularly
advantageous since it allows the ventilator 10 to be placed quickly and easily on its mount 20
in two successive main steps, as are illustrated in Figure 7, namely:
- firstly, initial mechanical positioning of the ventilator on its support by simple
insertion of the hooking tab 21 into the first seat or opening 11 of the panel 1 of the ventilator
15 10 (Position (1) in Fig. 7),
- then, simultaneous or almost simultaneous mechanical and electrical connection of
the system, with the ventilator 10 being locked on the mount 20, when the user pushes the
ventilator 10 in the direction of the mount (Position (2) in Fig. 7, and Arrow "PUSH), thereby
causing an actuation of the detent 40 by the panel 1, and its cooperation with the abutment 13,
20 and, at the same time, a withdrawal of the contact covers, and an electrical connection by
virtue of the male electrical contacts 52 of the mount 20 coming into connection with the
female contacts 5 1 of the ventilator 10.
When the user wishes to use the respirator away from its support device, the
mechanical and electrical disconnections of the ventilator 10 from the mount 20 are also
25 simultaneous and take place when the user actuates the lever 6, which then acts on the detent
40, which is tilted and thereby releases the panel 1, and the contact cover pushes the ventilator
10, which returns to its initial mechanical position, that is to say the unlocked coupling
position.
The respiratorlwall mount assembly according to the present invention can be used to
30 ventilate any type of patient requiring respiratory assistance, especially in emergency
interventions.
