This invention relates to an apparatusifor
inhalations and concerns more particularly an
apparatus of the kind in which the vapours from
the medicinal products intended for the `treat
5 ment of the affections of the respiratory pas~v
sages, may be inhaled either through the nose
or through the mouth and breathed or expired
1‘0‘
the chamber constitutes in a way a mask that
will ñt the nose and mouth perfectly. Partition ’51`
2l is arranged in such a manner that when the
directly into the outer air without getting mixed
patient has applied his face to the upperedge
of' the separator therev is no communication be
with the said vapours to be inhaled.
tween compartments Y25 and 26.
The apparatus according to the invention
which is of the kind provided with a hood above
the receptacle in which the medicinal vapours
are produced is essentially characterized by the
fact that the hood ends with a connection or
15 nozzle intended to receive one of two hollow ex
tension pipes of a buccomasal separating device
formed with a chamber divided into two comu
partments intended to receive the nose and the
mouth of the patient respectively and adapted
20 to be placed in communication with the outer
air by the forementioned extensions.
The invention also comprises a dropper device
intended to incorporate the medicinal product
with the solvent fluid, so as to provide for an
25 eflicient inhalation.
The invention is illustrated in the accompany
ing drawing showing by way of example an in
halation apparatus according to the invention,

responding to the nose and mouth respectively.
The walls of the said chamber 24, and in par
ticular their upper edges, have such a shape that
Fig. 1 is an elevation sectional view of the
apparatus,
Fig. 2 is a sectional view according to Ill-_II
of Fig. 1,
Fig. 3 is a sectional view of the bucco-nasal
35 separator according to III»-III of Fig. 1.
Fig. 4 is a sectional view of a dropper device.
Fig. 5 is a plan view corresponding to that of
Fig. 4.
Figs. 6 and 7 are views similar to those of
40 Figs. ¿l and 5 showing an alternative embodiment.
According to the embodiment shown in Figs.
1 to 3, the inhalation apparatus is, in the usual
manner, provided with a bottom receptacle 2l,
from. which emanate the vapours intended for
45 the treatment of the whole or a part of the
respiratory passages.
Receptacle 2l is covered by an upper part
or hood chiefly made up of a truncated body
22 resting with its large base upon the circular
50 edge of receptacle 2i and formed at its upper
end with a cylindrical connection or nozzle 23.
The apparatus is completed by a bucco-nasal
separator device of moulded material preferably
formed with a chamber 24 divided by a parti
55 tion 21 into two compartments 25 and 26 cor
i
,Each compartment 25 or 26 has its botton 10i
opening into a cylindrical extension 28 or 29
intended for insertion in nozzle 23. The exten
sions end preferably in the form of a cup, their
lateral wall being provided :with an .opening 38
and 3l communicating with the 'inside of hood 15ï
22 when the corresponding connection is in
serted in nozzle 23.
In order to obtain the proportion of air re
quired for the mixture suitable for inhalations,
hollows 32 for the admission of air, may be made 20
in the edge of receptacle 2 l.
The bucco-nasal separator being mounted as
shown in Fig. l it is apparent that the patient
can inhale the medicinal vapours through the
nose and breathe them out through the mouth 5
directly to the atmosphere through cylindrical
extension 22 and opening 3i.
When extensionv 29 is inserted in nozzle 23,
the vapours are breathed in through the mouth 30
and breathed out through the nose. The cups
provided at the bottom of extensions 28 and 29
serve as collectors to receive the fluids that are
secreted by the nose or mouth in the course of
the treatment.
35
In order to obtain an efficient and uniform in
halation throughout the duration of the opera
tion it is preferable that the medicinal product
should be incorporated with the solvent fluid in
a regular manner, for example, drop by drop.
40
In Figs. 4 to 7 are shown two forms of embodi
ment of a distributing device making it possible
to attain this result.
In the example of Figs. 4 and 5, the device
which is intended more particularly for use in 45
the above-described inhalation
apparatus
is
formed by a metal blank pressed so as to have
in its centre a cup 33 from which extend two
tabs 34 and 35, the ends of which are bent
down. The bottom of the cup is provided with 50
a hole or outlet 36.
When the device is mounted in position, with
its tabs in the hollows 32 of recipient 2|, cup 33
is ñlled with the medicinal fluid which flows drop»
by drop into the solvent within the receptacle 55
2
2,127,802
through hole or outlet 36 opening out, preferably
above the level of the said solvent.
In the case of Figs. 6 and '7, receptacle 37 pro
vided at the bottom with an outlet 38 is integral
with an element 39 in the shape of a cup form
ing a ñoat. The bottom of receptacle 31 is above
the bottom of cup 39, in order that, when the
whole is floating on the solvent fluid, the medic
inal product contained in receptacle 31 may flow
10 out drop by drop through hole or outlet 38.
’I'he
walls which connect receptacle 31 to element 39
are provided with holes 40 intended to allow the
passage of medicinal vapours.
It is obvious that the invention is in nowise
15 limited to the embodiment which has been more
especially described by way of example, but that
it extends to all possible modiñcations coming
fairly within the scope of the appended claims.
I claim:
l. In an apparatus for inhalations, a bucco-l
nasal separating device comprising a hollow body
having a rim adapted to fit over the nose and
mouth of the wearer, an air tight partition di
viding said body into a mouth chamber and a
25 nose chamber, and a hollow extension depend
ing from each chamber, each extension having
a closed lower end forming a receiver and hav
receptacle and having a vapor outlet, said vapor
chamber having inlets for admitting air thereto,
and a bucco-nasal separating device comprising
a hollow body having a rim adapted to ñt over
the nose and mouth of the wearer, and an air 5
tight partition dividing said body into a mouth
chamber and a nose chamber, each of said cham
bers having an opening adapted to connect said
chamber with said outlet, said opening permit
ting either inhalation or exhalation therethrough, 10
whereby either chamber may selectively be used
for inhalations from said receptacle, the opening
through the other chamber discharging the prod
ucts of respiration in the atmosphere.
3. In an apparatus for inhalations, a receptacle
having a hood upwardly extending therefrom,
said hood forming a vapor chamber with said
receptacle and having a vapor outlet, said vapor
chamber having inlets for admitting air thereto,
and a bucco-nasal separating device comprising 20
a hollow body having a rim adapted to ñt over
the nose and mouth of the wearer, and air tight
partition dividing said body into a mouth cham
ber and a nose chamber and a hollow extension
from each chamber, each extension being 25
adapted to register with and to be inserted
through said outlet, each extension having a
ing an opening through its side wall, whereby
either chamber may selectively be used for in
30 halation, the opening through the wall of the
closed outer end forming a receiver and having
an opening through its side wall, whereby either
chamber may selectively be used for inhalations
extension of the other chamber discharging the
from said receptacle, the opening through the
wall of the extension of the other chamber dis
products of respiration into the atmosphere.
2. In an apparatus for inhalations, a receptacle
having a hood upwardly extending therefrom,
