Improvements in Vaginal Syringes.
I HARRY AUGUSTUS SMYTHE MARTIN of 34 Walbrook in the City of London
Gentleman 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 :-
This invention is an improvement of that class of vaginal syringes formed of a
rigid vaginal tube having a compressible elastic bulb directly attached thereto
combined with an elastic air conducting tube with a small drip bulb directly attached
to the compressible elastic bulb. In vaginal syringes of this class the air tube is
composed of elastic and runs from the nozzle of the vaginal tube to the further end
of the compressible elastic bulb and is there directly connected with the small drip
bulb. The elastic air tube is liable to become twisted or choked and by this means
to prevent the ingress or egress of air and the efficient operation of the syringe and
as the compressible elastic bulb is fixed to the vaginal tube and must be so fixed on
account of the elastic air tube being fastened to the nozzle of the vaginal tube at
one end and to the further end of the compressible elastic bulb at the other end
such bulb cannot be taken apart from the vaginal tube for the purpose of the
necessary cleaning of either of the same. It is also an objection to vaginal syringes
of this class that no provision is made to prevent by means of a suitable shield
the air from entering the vagina at its orifice which entrance of air induces and
permits the liquid injected to escape at the orifice and otherwise interferes with the
efficient working of the syringe.
The object of my invention is to remedy these defects and for this purpose
I provide an air tube attachment and shield in the manner represented in the
accompanying drawing which shews a longitudinal central section of a bulb
syringe having such attachment and shield. The compressible elastic bulb A has
the ordinary shape and is attached to the vaginal tube B at the point F by a screw
coupling of gutta percha or other suitable material. The tube B has a series
of divergent but concentrically arranged holes "a a" in its nozzle and through
which the liquid used in treatment is alternately injected and withdrawn.
The air supply tube C, is made of gutta perchia or other suitable rigid
material and is secured or otherwise fixed to the nozzle end of the tube B at the
point G having at that end an aperture, through which the air passes, such air
tube C. extends from the point G to the point "e" in the tube B where an elbow
is formed with a thread cut therein to receive the spiral part of the hollow screw
end of D. The air chamber D is composed of gutta perchia or other suitable
material, having a series of air admitting holes "d" with a hollow spiral end
attached which spiral end is screwed or otherwise fixed through the tube B into
the elbow of the air tube C. making a continuous hollow rigid air chamber from
the air chamber D to the aperture at the point G. The spiral end of D is screwed
through B. behind the shield E at the point K.
The shield E is composed of gutta perchia or other suitable material of a rigid
nature and is fixed on the tube B at the point H. The shield E is preferably of an
oblong shape and somewhat concave and around the edge of the shield on the face
or concave surface a band or tyre of india-rubber or other suitable material is fixed
so that when the same is pressed against the mouth or orifice of the vagina the
same will prevent the ingression or egression of air.

page_text: In using the syringe the bulb A is first compressed in the hand and the tube B
inserted in the liquid to be injected and being relieved of compression the bulb A
expands and becomes filled with the liquid. The tube B being then inserted in the
vagina until the shield E rests firmly against the mouth of the vagina the bulb A
is then compressed suddenly, this expels the, liquid and causes its injection through
the holes "a a " and throws it about the uterus and wall of the vagina. Upon
slowly releasing the bulb from compression the liquid will be drawn back into the
bulb A with all other fluids and matter secreted and washed loose by the injection.
The action of atmospheric pressure forces the air in at the air chamber D and
through the small tube C. and allows the suction to proceed so causing such
withdrawal.
Having now described my invention and the manner in which the same is to be
performed 1 claim.
1st. The combination of the rigid air conducting tube C. with the tube B and
the detatchable bulb A as set forth.
2nd. The combination of a shield as described with a rigid air conducting tube as
described and the detatchable bulb and vaginal tube of a vaginal syringe as set
forth as and for the purpose specified.
