I, ROBERT PARK, of 275 Argyle Street, Glasgow, Lanarkshire, Doctor of
Medicine, Member of the Royal College of Veterinary Surgeons, &c do hereby
declare the nature of my invention for "IMPROVEMENTS IN SYRINGES FOR
INJECTING THE GENITO-URINARY PASSAGES AND OTHER ANALOGOUS CONDUITS OF
ANIMALS," to be as follows :—
My invention has reference to improvements in the construction of india-rubber
syringes used for medical, cleansing or sanitory purposes, which will make
them more efficient in their action and more convenient in application than
heretofore..
The improvements of my invention consist in forming and fitting to these
syringes an improved construction of injecting tube composed of gum elastic
catheter having formed round it at the neck, near the hollow ball pump, a collar of
soft elastic rubber to close the orifice of the passage and prevent the escape of the
injection. The bulbous nozzle of the tube is slightly elliptical in cross section and
is perforated all round with small lateral holes, while at the extreme end there is
secured or formed a soft elastic cap over the outer part of the perforated bulb,
which forms a barrier so that the injection may not pass it, but by its reflux
distends the passage between the cap and the collar, for the better action of the
fluid in its motion. The india-rubber ball is preferably fitted in a hollow rigid cup
of vulcanite or other material, so that the back part of the ball can be pressed and
doubled in on the front part within the cup, and a short conoidal nozzle may be fitted
in the throat of the ball leading into the section of the injection tube, and a conical
stopper would be formed on the inner back end of the ball, which when pressed as
stated by an outer knob for the purpose the stopper would close the conical nozzle
or open it sufficiently to allow of a return of the fluid to keep it in motion when
desired.
To make this syringe suitable for application in the vagina, for giving the same
advantage of distension of the passage and reflux of the injection, it would be
necessary to make the soft elastic india-rubber collar at the neck considerably
larger and elliptical to the upper side, while the perforated extreme end would be
of a hollow spoon shape, soft and rounded at the edges, and would not require any
cup or collar barrier as in the former application.

I, ROBERT PARK, of 275 Argyle Street, Glasgow, Lanarkshire, Doctor of
Medicine, Member of the Royal College of Veterinary Surgeons, &c 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 in writing, reference being had to the accompanying Sheet of Drawings,
and to the letters and figures marked thereon, that is to say :-
My invention has reference to improvements in the construction of india-rubber
hollow-ball syringes used for medical, cleansing, and sanitary purposes, which
improvements will make such syringes more efficient in their action and more
convenient in application than heretofore.
Figure 1 of the drawings, is a longitudinal section of an india-rubber ball
syringe for injecting the male genito-urinary passages or the rectum, and con-
structed in accordance with my improvements as applied thereto. Figure 2 is a
longitudinal horizontal section of an india rubber ball syringe for injecting the
female genito-urinary passages, and constructed in accordance with my improve-
ments as applied thereto. Figure 3 is an angled side view of the same general
construction of my improved syringe shown in Figure 2, with the india-rubber ball
part shown in section, the ball being somewhat simplified from that shown in
Figure 2, in dispensing with the vulcanite or other rigid cup C for compressing
it into.
Referring to Figure 1, my invention consists in forming and fitting to these
syringes an improved construction of the gum elastic catheter injecting tube A,
having formed round it at the neck near the hollow pump ball B, a circular
collar a of soft elastic rubber, to close the orifice of the passage when inserted and
prevent the escape of the injection. The improved bulbous nozzle b, of the tube A
is slightly elliptical and perforated all round with small lateral holes, while at the
extreme end beyond the holes there is formed or secured a soft elastic cap c
projecting back over the outer part of the perforated bulb b, and which forms a
barrier when pressed out by the injection, so that this may not pass it, but by its.
reflux distends the part of the passage between this cap barrier c and the collar a
for the better action of the fluid in its motion.
Referring to Figures 2 and 3.-In these larger syringes for the vagina, the india-
rubber ball or pump B, would be very much larger than in the modification shown
in Figure 1. The ball B may be fitted in a hollow cup C of vulcanite or other
rigid material, as shown in Figure 2, so that the back or outer part of the ball can
be pressed and doubled in on the front part within the cup C when injecting the
liquid. Or the ball B may be made without the cup C, as shown in Figure 3, 80
that the outer part of the ball may be compressed disc-wise with the palm of the
hand without a knob B¹, close up to the inner part of the ball and so discharge the
whole of its contents. In either case, a short tubular or conoidal nozzle part & may
be formed in the throat of the ball B and neck of the injecting tube A; and a

page_text: conical stopper d¹ would be fitted on the inner back end of the ball B, which when
pressed in, as stated, by an outer knob B¹ or projection B2 for the purpose, would
cause the stopper d¹ to close the conical nozzle d, but would open it when drawn
back sufficiently to allow of a return of the fluid into the ball to keep it in motion
to any degree desired.
To make this syringe suitable for application in the vagina, for giving the same
advantage of distension of the passage and reflux of the injection, it would be
necessary to make the india-rubber or vulcanite collar a¹ at the neck very con-
siderably larger and elliptical to the upper side. The tube A in this case would be
made broad and rounded at the back and edges A1, A2, as seen in the sectional view
Figure 2 A, while the extreme end 6' would be hollow and of a spoon-like shape
perforated all over and all soft and round at the edges; and, as shown in Figure 3,
it would not require the cup C shown in Figure 1. By compressing the ball B the
injection would pass through the interior of the tube A, out through the small
holes and all round the spoon-shaped end 61, acting in its reflux on the sides of the
passage, and returning outside the tube A, passes through the soft angled tung
valve e into the throat of the tube A, thence into the ball B, to be again forced
forward through the tube A, shutting the valve e when forcing and opening it by
the return of the injection and the pressure in the passage.
These ball pumps do not require to be unscrewed to fill them with the injection
fluid, but can be filled by merely inserting the perforated end of the tube into a
vessel containing the fluid, and by compressing all air out of the ball and releasing
it again, the ball in resuming its normal shape will fill itself with the liquid.
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. The general construction or combination of parts of india-rubber ball
syringes, substantially as, or in the manner and for the purposes herein described
in reference to and shown respectively in Figures 1, 2, and 3 of the accompanying
Drawings.
Second. The making of india-rubber ball syringes, for injecting the genito-
urinary passage, with a soft india-rubber collar a, at the neck of the tube, and an
improved bulb b perforated all round and with a soft india-rubber cap c over its
point, substantially as described in reference to and shown in Figure 1 of the
accompanying Drawings.
Third. The making of india-rubber ball syringes, for injecting the vagina, with
an improved construction of elliptical round-edged hollow tube A, A1, A³, with
spoon-shaped hollow perforated end b, of india-rubber or equivalent soft material
with a return current valve e, and either having the internal conical stopper d' or
the
cup C under the rubber ball B, or not, all as described in reference to Figures 2
and 3, respectively, of the accompanying Drawings.
