Improvements in Inhaling Appliances for Treating Lung, Throat,
and Nasal Complaints by Inhalation, and in Materials for use
therein.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., of 96 Amhurst Park, London,
Analytical Chemist, 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:--
Instead of using a liquid as is usual in many forms of inhaling apparatus I
employ a mixture through which it is possible to pass or filter a current of air viz. a
medium such as sawdust, wood-pulp, bread cut in blocks or crumbled, granulated
coke or charcoal, cotton wool or cotton waste, or plaster of Paris, cast in suitable
pieces or cast into the vessel itself moistened with Sanitas oil. For example I
employ sawdust containing in admixture say from 10 to 50 per cent. of Sanitas oil.
The porous mixture is placed or contained in the apparatus through which it is
possible to draw by suction or inspiration a current of air so that in this
medicated vapour may be inhaled for the treatment of lung, throat and nasal
complaints.
way the
Again for example I make a mixture of plaster of Paris (with admixture of
pulverised coke or similar material to increase its porosity if desired) and water
and whilst fluid pour it into the apparatus so as nearly to fill same.
The mixture
is then allowed to set so as to take the shape of the vessel and is then allowed or
made to dry by heating in a suitable hot chamber, after which Sanitas oil is
gradually poured on it until it will not absorb more. In this way the plaster may
be made to absorb about 50% by weight of Sanitas oil.
There are several important advantages secured by this system. In the first
place the use of a liquid alone is avoided and the apparatus is therefore more
portable and free from the objections which might result in cases of breakage or
leakage where liquids alone are used. In the next place the current of air is
filtered and thus any objectionable micro-organisms which may be present in the
air are removed before it passes charged with the medicament or inhalant into the
mouth and respiratory passages. Further a current of air either heavily or lightly
charged with the medicament or inhalant can be in this way obtained at will the
result being dependent upon the proportion of active ingredient placed along with
the porous filtering medium.
The drawing annexed shews two forms of the apparatus I employ. In the form
shown in Figure 1 the air is made to enter the chamber containing the medicated
mixture through a hole or aperture at the top of a cone which rises up into the
chamber from its base. In Figure the hole is situated at one side near the bottom
of a flat bottomed vessel. Another way of admitting the air is through a tube led
down through the stopper with which the mouth of the bottle is closed as in other
inhaling apparatus.
A is the bottle tin box or other containing vessel.
B a cork or stopper or lid with aperture fitting same.
C the small orifice at crown of the base or at one side which may be lightly
plugged with cotton wool.
D is the tube used for inhaling; it may dip down into the porous material
contained in the bottle as shewn or may terminate at the bottom of the stopper.
At E the tube D is lightly plugged with cotton wool.
F is mouthpiece of tube D as flattened for placing in the mouth.
On applying the mouth at F and inhaling, air enters the apparatus at C and is
thus made to filter through or permeate the contents of the vessel. The air thus

page_text: entering carries with it the vapour of the volatile Sanitas oil and the medicated
vapour is thus inhaled.
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 :-
1. The use of Sanitas oil, admixed with a porous filtering medium such as
sawdust or the other substances hereinbefore named in connection with inhaling
apparatus by which air can be drawn through the porous mixture and inhaled for
the treatment of throat, lung and nasal complaints.
2. An inhaling appliance composed of a bottle or containing vessel having an air
inlet near the bottom and filled or partially filled with plaster of Paris cast into it
and made to absorb a quantity of Sanitas oil-a cork or stopper closing the mouth
of the bottle an inhaling tube passing through the stopper and a flattened mouth-
piece on the outer end of the tube.
3. Inhaling apparatus constructed as shown in Figure 1.
