COMPLETE SPECIFICATION.
Improvements in Inhalers, also applicable as Nasal Douches.
JAMES MONROE MUNYON, of 1505, Arch Street, Philadelphia, United States
of America, President of a Company, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention relates to an improvement in an inhaler and nasal douche and
consists of an interior vessel formed of detachable parts for convenience of access
to the interior thereof and simplicity and inexpensiveness of construction.
It also consists in providing the exterior vessel with a cap which supports
the interior vessel and has the mouth and nose pieces attached thereto.
It also consists in providing the side of the interior vessel with a recess below
said cap whereby an expansion chamber is provided and a free communication
formed between the two vessels employed.
In the accompanying drawings:-
Figure represents a side elevation of an inhaler and nasal douche embodying
my invention.
Figure 2 represents a vertical section thereof.
Similar letters of reference indicate corresponding parts in the figures.
A designates a vessel which is provided with the cap B to which are attached
the mouth piece or tube C and nipple D, the latter being adapted for the con-
nection of the nose piece or tube E which is in general of an elastic or flexible
nature.
Secured to and depending from the cap B is the interior vessel F which is
in communication with the nipple 1 and consequently with the nose piece and
has in its side the port or opening G whereby the two vessels are in communi-
cation, it being noticed that the mouth piece C is in communication with the
outer vessel A.
In the exterior wall or side of the vessel F, below the cap and adjacent to
the inner end of the mouth piece C is the recess H which provides an expansion
chamber between the two vessels at said point, and is formed in the present case
by indenting the wall of said vessel F.
The vessel F is formed in sections detachably connected by a screw-threaded
joint whereby they may be readily separated for the purpose of supplying
and replenishing said vessel with its medicament or for the purpose of cleansing,
repairs, etc.
The method of employing my invention is as follows;
In using my invention as a nasal douche proper medicaments are placed in
the two vessels A and F and the piece E is inserted in one of the nostrils while
the piece C is inserted in the mouth. The breath is now blown into the vessel A
through said piece C whereby the vapour of the medicament in said vessel is
directed through the port or opening G into the vessel F where it commingles
with the vapour in the latter, the united vapours then passing through the
piece E into the nostril.

page_text: For inhaling purposes the piece E is removed from the nose and the vapours
drawn from the two vessels through the mouth piece C, it being noticed that
air is supplied to the vessel F through the piece E, as the air in-take when
the vapour leaves said vessel through the port or opening G, enters the vessel A
and commingles with the vapour in said vessel A, and from thence the united
vapours enter the piece C as the discharge and so reach the mouth, throat, etc.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1st. In an inhaler and nasal douche, an inner vessel formed of sections detach-
ably connected.
2nd. In an inhaler and nasal douche, an exterior vessel, a cap therefor, an
interior vessel depending from said cap and inlet and outlet tubes connected
with said cap.
3rd. In an inhaler, an inner vessel having a port or opening in the wall
thereof, an exterior vessel, a cap on the latter vessel and a mouth piece and an
air supply tube connected with said cap.
4th. In a device of the nature of an inhaler, nasal douche, and the like, an
interior medicament vessel having a recess in the exterior thereof adjacent to
the end of the inhaling or exhaling tube of the device.
5th. An exterior vessel, a cap thereon, inlet and outlet tubes on said cap, and
an interior vessel, depending from said cap, said interior vessel being formed
of detachable sections and having a recess in its exterior adjacent to the end
of either of said tubes on said cap.
