Breathing Regulator.
A communication from HEINRICH SIMONS, Hospital Director, of 41, Kaiserallee,
Aix-la-Chapelle, in the Empire of Germany.
I, ALFRED JULIUS BOULT, of 323, High Holborn, in the County of Middlesex,
Chartered Patent Agent, 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 :-
The object of the instrument which in the accompanying drawings is represented
about twice its actual size is to serve as a means for regulating the operation of
breathing and thereby purifying the blood and strengthening the lungs.
It consists of a short tube a tapering somewhat towards its front end, where it is
closed by a valve c which is attached to a spring b.
The regulator is used in the following manner;-
The end d of the instrument is placed in the mouth and holding it tightly with
compressed lips, the used up or impure air contained in the lungs and loaded with
carbonic acid gas, is blown out through the instrument with such force that the
valve c is raised and assumes the position indicated in Figure I by dotted lines.
In this way the lungs are emptied from the used up or vitiated air to an extent
that cannot be attained in the ordinary movement of even the strongest expiration.
As soon as expiratory action ceases, the valve c, closes, and the air of inspiration
made to enter by way of the nostrils so that it may reach the lungs warmed and free
from dust. The preceding full and abundant inspiration will have increased the
capacity of the lungs for taking up a supply of air larger than that conveyed to
them in ordinary unassisted breathing. Hence a deep inspiration ensues, by which
an abundant supply of oxygen is conveyed to the lungs, and resulting in the
purification of the deoxygenated venous blood from carbonic acid and its con-
version into oxygenated arterial blood, a most natural and rational! blood
purification being in this way established in the body.
The strengthening of the lungs above referred to results in consequence of the
resistance offered by the valve e which is closed by the pressure of the spring, to
the air expelled from the lungs, and by the additional force called forth accordingly
to overcome this resistance, the lungs are strengthened.
b
The protector e arranged above the valve c and spring serves to protect the
spring and valve from damage, inasmuch as the protector in order to be used at
any time, is intended to be worn by a cord or ribbon fastened round the neck and
passed through the eyelet f.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is ;-
An instrument for regulating the breathing consisting of a short tube such as a
which is placed between the lips and closed at its front end by a valve such as c
kept closed by the pressure of a spring such valve opening when the impure air is
expired from the lungs and closing when the external air is inspired so that the
latter action can only take place by way of the nostrils.
Dated this 20th day of October 1893.
