Improvements in Syringes.
I, ARTHUR BENJAMIN CRUICKSHANK, of 21 Sutherland Place, Bayswater, in
the County of London, Mine Proprietor, do hereby declare the nature of this
invention to be as follows:-
My invention relates to improvements in syringes, whereby the liquid to be
introduced into the vagina, or other cavity to be cleansed, and its withdrawal
therefrom, are both effected by suction.
For this purpose, the syringe consists of two flexible tubes connected to a vaginal
tube or nozzle having a widened base, one of these tubes being the supply tube
and the other the discharge or waste tube. The supply tube is provided, at its
free end, with a valve, and the waste tube is provided, at any suitable point in its
length, with a compressible bulb, and with two valves, one above and the other
below the bulb, both these valves being arranged to open in the same direction.
The vaginal tube, or nozzle destined to be introduced into the vagina, or into
any other cavity to be cleansed, is formed with two longitudinal passages or
channels, one communicating with the supply tube and the other with the discharge
or waste tube; and the top of this vaginal tube or nozzle is perforated, or of
skeleton construction, to allow ready delivery of the liquid on to the part to be
cleansed, and its entry into the waste tube. By compressing the bulb and then
allowing it to expand, the expansion causes the liquid, to be introduced, to be drawn
by suction from a supply vessel through the supply tube, and to pass into the
vagina (or other cavity) and out of the same into the upper end of the waste tube
and into the bulb; and by again compressing this bulb, the compression causes the
liquid therein to be ejected or discharged through the lower part of the waste
tube, this discharge or waste liquid being received in a suitable vessel.
The liquid-supplying vessel may, if desired, be arranged at any convenient
elevation, and the supply tube, in such case, be connected therewith and be provided
with a stop-cock for retaining the liquid in the vessel when the syringe is not in
operation; the valve in the supply tube being then dispensed with.

Improvements in Syringes.
I, ARTHUR BENJAMIN CRUICKSHANK, of 6, Westmoreland Road, Bayswater,
in the County of London, Mine Proprietor, 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:-
My invention relates to improvements in syringes, whereby the introduction of
the liquid into the vagina, or other cavity to be cleansed, and its withdrawal
therefrom, are both effected by suction.

page_text: For this purpose, the syringe consists of a vaginal tube or nozzle, having a
widened base, to which are connected two flexible tubes, one being the supply or
induction tube, and the other the waste or eduction tube. The waste or eduction
tube is provided, at any suitable point in its length, with a compressible bulb, and
with two valves one above and the other below the bulb, both these valves being
arranged to open in the same direction.
The vaginal tube or nozzle, destined to be introduced into the vagina, or into
any other cavity to be cleansed, is formed with two longitudinal passages, or
channels, one communicating with the supply or induction tube, and the other with
the waste or eduction tube, and said tube or nozzle bas a transverse or cross
passage or channel connecting the two longitudinal channels near their upper end.
The liquid supplying vessel may, if desired, be arranged at any convenient
elevation, and the supply or induction tube in such case be connected therewith,
and be provided with a stop cock for retaining the liquid in the vessel when the
syringe is not in operation.
And in order that my invention may be readily understood, I proceed to
describe the same fully with reference to the accompanying drawings, in
which :-
Fig. 1 is a general elevation of the apparatus, and
Fig. 2 is a vertical section, to a larger scale, of the upper part of the nozzle.
Figs. 3 and 4 are also vertical sections, to the same scale as Fig. 2, of modified
constructions of the nozzle.
a is the flexible induction tube, & the flexible eduction tube having a compressible
bulb c interposed in its length, the portion above the bulb forming the suction
portion, and that below the bulb the discharge portion. d is the nozzle to which
are connected said tubes a and b.
The nozzle is formed with passages or channels d', d, the former being the
induction passage, and in connection with the induction tube a, while the latter is
the eduction passage and in connection with the eduction tube b. is the transverse
passage uniting the induction passage d' and the eduction passage d², said passage d'
being shown as a straight hole opening at its ends through the sides of the nozzle,
and being situated very close to the upper end of the nozzle.
The eduction tube is furnished above and below the bulb, with valves e, e', of any
suitable construction, opening in a downward direction.
The induction tube, induction passage, cross passage, eduction passage, and upper
part of eduction tube, form a continuous channel from the liquid supply vessel to
the bulb.
By compressing the bulb, and then allowing it to expand, the expansion causes
the liquid in the supply vessel to be drawn along this continuous channel until it
reaches the cross channel, when the inertia of this liquid causes it to leave the
continuous channel and pass out at the upper end of the nozzle and wash out the
cavity to be cleansed, before returning to the eduction passage and following its
natural course into the bulb. By again compressing the bulb, the compression
causes the liquid therein to be ejected or discharged through the lower portion
of the eduction tube, this discharge or waste liquid being received in a suitable
vessel.
The washing out of the cavity to be cleansed, being effected by suction gives
much greater efficiency than by the ordinary methods.
In the modified arrangement shown in Fig. 3, the transverse passage d' is within
the perforated hemispherical end d' of the nozzle, and in Fig. 4 it is only
between the passages d' and d, and does not extend through the sides of the.
nozzle.
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. The improved syringe, whereby the introduction of the liquid into the vagina,

page_text: or other cavity to be cleansed, and its withdrawal therefrom, are both effected by
Buction, substantially as set forth.
2. In a syringe, the combination of a nozzle, a supply or induction tube for
liquid, and a waste or eduction tube, said eduction tube having a bulb and valves,
whereby the washing action is effected by suction, substantially as described.
3. A nozzle for syringes, having an induction passage and an eduction passage,
and a passage or water way within the nozzle connecting the induction and eduction
passages, substantially as described and shown.
