AN IMPROVED VAGINAL INJECTION CANHLA”
Year: 1874

page_text: LETTERS PATENT to Joseph Delioux de Savignac, of Paris, in the
Department of the Scine, Republic of France, Doctor, for the In-
vention of "AN IMPROVED VAGINAL INJECTION CANHLA”
PROVISIONAL SPECIFICATION left by the said Joseph Delioux de
Savignac at the Office of the Commissioners of Patents, with
his Petition, on the 1st July 1874.
I, JOSEPH DELIOUX DE SAVIGNAC, of Paris, in the Department of the
Seine, Republic of France, Doctor, do hereby declare the nature of the
said Invention for "AN IMPROVED VAGINAL INJECTION CANULA," to be as
follows:-
The canula, the subject of this Invention, is made of gum, is soft,
flexible, and has a total length of about eight inches (20 cents.), six
inches (15 cents.) for the tube, two inches (5 cents.) for the bulbous end.
As shown on the accompanying Sheet of Drawing the sides of the
bulbous end instead of being thin as in most instruments of this kind
are solid, so that instead of constituting a dilatation in form of a blister it
is hollowed by a channel in continuation without modification of diameter

page_text: of that of the body of the canula. The solid part of this bulbous end is
formed of an interior bulb of caoutchouc inserted and held between the
layers of gum and the canvas which form the substance of the canula, a
novel and important addition giving strength and firmness to the
instrument and favouring clean perforation of the orifices.
th
The bulbous end is pierced with twenty-four small rectilineal channels,
each having a diameter of 22th of an inch (2 millimètres); these small
channels are oblique from the inside to the outside and upward, they
end exteriorly in twenty-four holes arranged in quincunx / of an inch
(1 cent.) apart in six lateral rows. The end of the bulbous part is blunt,
rounded, and non-perforated; most vaginal canulas are on the contrary
perforated at the top, and generally with a much small number of holes.
With the exception of a slight widening at the lower end of the canula
to facilitate its fitting to an injecting apparatus the inner channel has
in its entire length up to its termination at the top of the bulbous end
a uniform diameter of 25th of an inch (1 cent.). My improved canula
thus represents the rose of a watering tube, the feeding of which is
mathematically ensured by a tube, the inner section of which is equal to
the total section of the twenty-four orifices. If it is fitted to another tube
having also in its entire length a diameter of the of an inch (1 cent.),
and if this tube is fitted to an opening of equal diameter in a vessel con-
taining water all the orifices of the bulbous end each give an equal
quantity of liquid with a speed and force in accordance with the power
of the means of impulsion. The result is a watering of the parts into
which this canula is introduced infinitely more complete than can be
obtained by the analogous instruments hitherto used. These advantages
are due to the mode of construction of the bulbous part, to the number
and arrangement of the orifices, and to the relative proportion estab-
lished between these and the inner diameter or caliber of the canula.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 3
filed by the said Joseph Delioux de Savignac in the Great Seal
Patent Office on the 1st January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
DELIOUX DE SAVIGNAC, of Paris, in the Department of the Seine,
Republic of France, Doctor, send greeting.

Letters Patent, bearing date the First day of July, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Delioux de Savignac, Her
› special licence that I, the said Joseph Delioux de Savignac, my
executors, administrators, and assigns, or such others as I, the said
Joseph Delioux de Savignac, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVED VAGINAL INJECTION
CANULA," upon the condition (amongst others) that I, the said Joseph
Delioux de Savignac, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed and cause the same
to be filed in the Great Seal Patent Office, within six calender months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Delioux de Savignac,
do hereby declare the nature of my said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
:-
The canula, the subject of this Invention, is made of gum, is soft,
flexible, and has a total length of about eight inches (20 cents.), six
inches (15 cent.) for the tube, two inches (5 cent.) for the bulbous end.
As shown on the accompanying Sheet of Drawing the sides of the
bulbous end instead of being thin as in most instruments of this kind
are solid, so that instead of constituting a dilatation in form of a blister
it is hollowed by a channel in continuation without modification of
diameter of that of the body of the canula. The solid part of this
bulbous end is formed of an interior bulb of caoutchouc inserted and
held between the layers of gum and the canvas which form the sub-
stance of the canula, a novel and important addition giving strength
and firmness to the instrument and favouring clean perforation of the
orifices.

The bulbous end is pierced with twenty-four small rectilineal channels,
each having a diameter of 2/25th of an inch (2 millimètres); these small
channels are oblique from the inside to the outside and upward, they
end exteriorly in twenty-four holes arranged in quincunx /** of an inch
(1 cent.) apart in six lateral rows. The end of the bulbous part is blunt,
rounded, and non-perforated; most vaginal canulas are on the contrary
perforated at the top, and generally with a much smaller number of
holes.
With the exception of a slight widening at the lower end of the canula
to facilitate its fitting to an injecting apparatus the inner channel has
in its entire length up to its termination at the top of the bulbous end a
uniform diameter of th of an inch (1 cent.). My improved canula
thus represents the rose of a watering tube, the feeding of which is
mathematically ensured by a tube, the inner section of which is equal
to the total section of the twenty-four orifices. If it is fitted to another
tube having also in its entire length a diameter of 2 of an inch (1 cent.),
and if this tube is fitted to an opening of equal diameter in a vessel con-
taining water all the orifices of the bulbous end each give an equal
quantity of liquid with a speed and force in accordance with the
power
of the means of impulsion. The result is a watering of the parts into
which this canula is introduced, infinitely more complete than can be
obtained by the analogous instruments hitherto used. These advantages
are due to the mode of construction of the bulbous part, to the number
and arrangement of the orifices, and to the relative proportion
established between these and the inner diameter or caliber of the
canula.
In witness whereof I, the said Joseph Delioux de Savignac, have
hereunto set my hand and seal this Twenty-ninth day of December,
