Improvements in Inhaling Apparatus.
I, HENRIK CHRISTIAN FREDRIK STORMER of Christiania, Norway, Engineer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
Inhaling apparatus as heretofore made have been on the principle of an inducing
pipe and jet of compressed air or steam for distributing the dissolved medecine or
medicated water or other fluid in the form of a fine spray cloud dust or fog.
But the particles thus induced and carried along by such inducing current and jet
are generally too large or coarse to penetrate thoroughly into the fine interstices or
channels in the lungs or bronchial parts, owing to the large amount of water uselessly
carried along therewith. The main object of this invention is to deprive the spray fog
or cloud of such useless water and thus to cause the medicine to penetrate more
thoroughly into the parts required.
The accompanying vertical sectional elevation illustrates the principle of my inven-
tion and a suitable form of apparatus for carrying it into effect.
A is the bottle filled with the dissolved medecine, such for instance as 1 part of
nitrate of silver to 1000 parts of water. The cap B of the bottle is provided with an
inlet pipe B1 for steam or compressed air, and an outlet jet pipe a nozzle B² whereby
the vapour from the medicated water in the bottle A is induced by, carried along with,
and mixed with the pressure fluid and projected into the tube C (which may be hori-
zontal as shewn or vertical or inclined) in the form of a watery cloud or fog which in
the tube C becomes mixed with and acted upon by a current of hot air coming from
the tube D, whereby the watery particles in the cloud or fog are absorbed and
evaporated so that the cloud is rendered dry or drier as required all according to the
heat of the air and the quantity thereof thus drawn into the tube C from the pipe D,
the current leaving the exit end C₁ of the tube C in a dry and minutely sub-divided
state suitable for entering the finest pores or interstices of the lungs or bronchial parts.
The hot air supply is obtained from any suitable source such as from a lamp or
stove.

page_text: If the medecine is to be quite dry and the solution of the nitrate of silver be as in
the example assumed roon then the weight of each minute globule of the watery
dust will be reduced to 10 of the original weight but the specific gravity of the
nitrate of silver being 4, the volume of each particle of the medecine will only be
4000 of the volume of each minute globule and these are small and light enough to
penetrate into the finest pores or interstices of the lungs and bronchial parts. The
size of the particles of medecine may be calculated beforehand, the strength of the
solution being made in accordance therewith. The apparatus may also be used for
inhalation of bacteries, microbes and microbe germs.
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 :-
First In an inhaling apparatus the application of an inlet for hot air to com-
mingle with the spray cloud or fog for the purpose of drying it or evaporating the
watery particles thereof.
Second-The inhaling apparatus shown and described consisting of the vessel A for
containing the solution or mixture the cap B with inlet B₁ for pressure fluid and the
jet nozzle B2 for injecting a cloud or fog into the receiver pipe C which is provided
with an inlet pipe D for hot air so that the spray or cloud leaves the exit C in a dry
state.
