Improvements in Syringes.
I, ARTHUR BENJAMIN CRUICKSHANK, of 24 Great Western Road, Westbourne
Park, in the County of London, Inventor, 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, reference being had
to the accompanying drawings and to the letters and figures marked thereon, that
is to say:
This invention relates to improvements in syringes whereby an alternate delivery
and suction of an injection into and from the vagina can be effected by means of
one and the same syringe, without it being necessary to remove the nozzle or
vaginal tube.
According to my invention I provide an elastic bulb or chamber having two
independent compartments one of which serves for the delivery and the other for
the suction. Each of these independent compartments is furnished with two
flexible tubes through which the injection enters and leaves the respective compart-
ments suitable valves being provided and so arranged as to regulate the flow.
These flexible tubes thus constitute two pairs of suction and delivery conduits,
the free extremities of one pair being connected to a flaring tube, formed with
two passages, which enters the vagina; and the free extremities of the other
pair being furnished with weighted end pieces, one of which enters the vessel
containing the injection and the other the vessel receiving the injection withdrawn
from the vagina.
In order that my invention may be fully understood and readily carried into
effect, I will describe the same fully with reference to the accompanying
drawing, which illustrates a vaginal syringe constructed in accordance with my
invention.
A is the elastic bulb or chamber which is divided into two independent
compartments a, b, by the partition c, the compartment a being for the suction
and for the delivery. Each compartment is furnished with two flexible
tubes a, a, b, 62, through which the injection is forced and withdrawn as herein-
after described. Valves a³, a, b, b, of ordinary and well known construction
are located between the compartments and these flexible tubes, and are so
arranged that the valves a³, ³, open, and a, b, close, when the bulb A is
compressed, while the valves a, b, open, and a³, 63, close, when the bulb is allowed
to again expand.
The free extremities of the tubes a¹, 61, are connected to the vaginal tube C
by means of the nipples a, b, with which it is furnished. This vaginal tube is
also provided with two passages a, b, through which the injection is discharged
into and withdrawn from the vagina, and is also formed with a flaring or gradually
increasing base so that it will act to prevent the injection from escaping from the
vagina when said tube is in place. The two tubes a, b, are preferably connected
together longitudinally, by a suitable rubber solution, or other means, so that
they will offer no inconvenience when the syringe is being used.
The free extremities of the tubes a, b, are furnished with end pieces a, b,
I also
having hooks a, b, for enabling the syringe to be suspended after use.
provide lead tubular pieces a, b, for giving additional weight to the ends of
these tubes and so as to ensure their not escaping from the vessel into which
they are placed. The tube a' is also furnished with a moveable hook d which
may be caused to engage with the edge of the vessel and thus enable the end of
such tube to be suspended above the level of the liquid in the vessel.

page_text: The manner of using the syringe is as follows:-
Two vessels are provided, one of which serves as a reservoir for the injection
and the other as a receiver for the withdrawn injection. The end a² of the tube a²
is suspended in the last mentioned vessel by means of the hook d in the manner
already explained, and the end 67 of the tube 62 is immersed into the injection
contained in the other vessel. The bulb A is then operated, as in an ordinary
Byringe, so as to cause the delivery compartment to become charged. The vaginal
tube C having been inserted into the vagina the bulb is then alternately compressed
and allowed to expand. At each compression the liquid in the delivery compart-
ment b is ejected along the tube b', and through the flaring tube C into the vagina,
while the liquid in the suction compartment a is expelled through the tube a³ into
its vessel, the valves a³, 63, opening during such compression. But each time
the bulb is allowed to expand, the valves a³, 63, immediately close and the valves a, b,
open, thus permitting the compartment b to charge itself with fresh injection from
the reservoir, and the compartment a to charge itself by withdrawing from the
vagina the injection which had been previously forced thereinto. By continuing
this alternate compression and expansion of the bulb the same cycle of operations
takes place at each compression and expansion.
It will thus be seen that by my invention an alternate action on the vagina is
produced-first douche, then suction-the suction serving as a drainage to allow
the water or other injection that has been used while washing the vagina to be
drawn off. At the same time every particle of foreign or diseased matter will also
be removed, which is not possible with an ordinary douche syringe. By reason
also of the flaring tube completely closing the vagina, it is possible by compressing
the bulb and retaining it in this compressed condition to keep an astringent or
caustic injection in contact with the walls of the vagina for any desired length of
time. Furthermore, a second or third injection can be consecutively used without
withdrawing the vaginal tube.
Instead of employing a bulb or chamber divided into two compartments as above
set forth, I may employ two separate bulbs preferably joined together longitudinally,
or kept in the same relative position to each other by having their tubes, which
are attached to said bulbs, connected just beyond the valves (by tying or other
means), each bulb being provided with a pair of valves, and each pair of valves
arranged to open in an opposite direction to that of the other pair.
Although I have shown and described the syringe as adapted for use as a
vaginal syringe, I can, if desired, employ it for washing out the stomach, or the
lower bowel, suitable tubes being used in place of the vaginal tube shown in the
drawing.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A syringe provided with an elastic bulb or chamber divided into two inde-
pendent compartments and furnished with suitable valves and tubes, whereby an
injection can be alternately injected and withdrawn from the vagina, stomach, or
lower bowel, without removing the vaginal tube, or other nozzle, substantially as
described.
2. In a syringe, the combination with an elastic bulb or chamber divided into
two compartments, of flexible tubes, furnished with suction and delivery valves,
two of which tubes are joined together longitudinally and have their free ends
connected to a vaginal tube, or other nozzle, formed with two passages, the other
two tubes being independent to allow their ends to dip into separate vessels,
substantially as described.
3. The construction and use of the divided bulb or chamber having two pairs of
valves, each pair being adapted to open in an opposite direction to that of the
other, substantially as described and shown.

to the annexed drawings.
