COMPLETE SPECIFICATION.
Portable Apparatus for Treating a Patient with a Medicated or
Tempered Atmosphere.
I, AUGUSTE CAZAUX, of Villa Verdier, Nice, Alpes Maritimes, France, C.E.
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 :-
This invention relates to simple and conveniently portable apparatus by which a
patient can be made to inhale medicated or tempered air and to have his body
subjected to the influence of such air at various degrees of pressure.
In the accompanying drawings I shew examples of the several parts of the
apparatus which I employ for this purpose, but it is to be understood that
details of these may be varied without departing from the essential character of my
invention.
Figure
illustrates the whole apparatus, the other figures illustrate details
hereinafter referred to.
As shewn in Fig. 1 the apparatus consists of the following parts :-
1. A loosely fitting dress A of light, strong, impermeable material, entirely
enclosing the body head and limbs of the patient, and having a mask, which may
be of glass, in front of the face.
2. A medicating or tempering vessel B in which air passing through it can be
impregnated with vapours, or heated or cooled.
3. An air compressing pump C.
4. Pipes connecting the pump C to the medicating or tempering vessel B, and
that vessel to the interior of the dress A; and other pipes hereinafter
referred to.
The 4 parts of apparatus above mentioned are constructed and arranged as
follows:-
1. The dress A is made in two portions, the lower portion or trousers D and the
upper portion E, these portions being tightly connected at the waist as shewn in
section in Fig. 6. The upper margin of the trousers D is folded over so as to
enclose a steel ringe of channel section, the edge of the folded over part being
united to D at D'. The steel ring e is considerably larger than the waist so that
there is perfect freedom within it; a band of caoutchouc presses the fabric of
the trousers against the interior of the steel ring c. The fabric of the upper
portion E is also folded over to enclose a caoutchouc band and within the folded
part is a band of leather or equivalent material which presses and its enclosing
fabric against f. As shewn in section in Fig. 5 the margin of the transparent
mask is engaged within an oval metal ring of U section having one limb of
the U elongated; the fabric E of the dress is folded over the short limb of the U
and extends to bear against the interior of the mask i which is thus held between
the margin of the fabric and a caoutchouc washer within the longer limb of k.
A steel ring n partly enclosed within a caoutchouc band serves to keep the parts
in position to make an impermeable joint of the mask to the fabric. When it is
desired to supply the patient with cordial or medicine, a flexible pipe o which is
passed through the fabric E and made gool by impermeable jointings p, terminates
within the dress with a slit mouth piece s forming a valve which closes against
escape of air under pressure within the dress but opens to allow liquid to pass when
which is
the patient sucks. The outer end of the pipe o is attached to a nozzle
usually screwed to a stopper r, but from which r is unscrewed when it is desired to
let the patient suck liquid from a phial or other vessel, to which the nozzle is in
that case connected. M is a pressure gauge and N a pocket.

2. The medicating or tempering vessel B, shewn in section in Fig. 2, is made of
metal internally tinned and is covered by a hinged lid which can be tightly
closed on a washer of caoutchouc. A nozzle R, provided with a spring check
valve T, admits the air from the pump C. A stop cock serves to drain off
moisture or other liquid. A valved outlet X has a nozzle X' to which is attached
the flexible pipe G which leads into the upper portion E of the dress A. Within
the vessel are several perforated diaphragms V on which are placed pine shavings
impregnated with antiseptic or other medicaments which can be introduced by a
filter Z, having two cocks, against the internal pressure which can be regulated as
desired by an adjustable spring safety valve s. The diaphragmns V are all attached
by a central bolt to the uppermost V, which rests on a shoulder, so that they can
all be lifted out together.
The vessel B is furnished with a pressure gauge . By heating or cooling
the vessel B, the air supplied to the patient may be varied in temperature.
3. The pump C, of which Fig. 3 is a vertical section, and Fig. 4 also a vertical
section on the line ed of Fig. 3, consists of two cylinders containing a quantity of
water which, by means of a packed piston 1 worked by lever 2 in the one cylinder 3,
is caused to move up and down in the other cylinder 4, thus causing air to be
expelled by valve 8 and drawn in by valve 7. By applying the piston to move
the water, the air pumped is not affected by the lubricant employed for the
piston.
4. Besides the pipe o for supplying the patient with liquid, there is the flexible
pipe R connecting the discharge nozzle 9 of the pump to the vessel B; there is
the flexible pipe G connecting the nozzle X of the vessel B to the upper part E
of the dress A preferably behind the patient's neck, and there is finally the pipe H
for escape of air from the interior of the dress, as determined by an adjustable
valve P.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The air tight dress A and mask i with the impermeable jointings, substantially
as described.
2. The medicating and tempering vessel B with its fittings, substantially as
described.
3. The pump C with water piston, substantially as described.
4. The pipes R and G connecting the pump Cand vessel B to the dress A, the
pipe H and adjustable valve P for escape of air from the dress, and the pipe o with
valve, nozzle and stopper, substantially as described.
5. The combination of the parts referred to in the preceding claims, constituting
portable apparatus for treating a patient with a medicated or tempered atmosphere,
substantially as described.
