COMPLETE SPECIFICATION.
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 relates to that class of vaginal syringes, in which a central air
tube admits air from the external atmosphere to the nozzle of the injection tube,
which is provided with a collapsible injection bulb, and consists in improvements in
the construction of the syringe and central air tube to adapt the instrument to a
curved or flexible injection tube, and to facilitate the manufacture thereof and the
access to and removal of parts for cleansing.
Figure 1 of the drawings annexed hereto shows a vertical section through my
improved device.
Figure 2 is an enlarged detail of the top joint of the internal tube, and Figure 3
is enlarged details of the bottom joint of same.
A is the injection tube which may be curved in any desired form, or flexible, and
is provided with apertures a for the discharge of the liquid contents of the
compressible bulb B, which is compressed by the grasp of the hand and is
detachable.
C is the air admission tube, of any convenient flexible material, such as india-
rubber. It is attached at the top end to an internal nozzle D, provided with a
central aperture d and a shoulder on the inner end over which the flexible tube is
secured. The said nozzle D is screwed into or otherwise attached to the end of
the main injection tube A. As shown, it drops onto a cone seating, and is secured
by a screwed sunk nut b on top.
Similarly the lower end of the tube C is attached over a shoulder to an elbow E,
inserted laterally through the walls of the main injection tube A. An air and drip
chamber F, provided with perforations fis screwed into or otherwise detachably
attached to the side wall of the tube A, so as to meet the elbow E and complete
the continuity of the air channel from the external atmosphere to the point of the
tube A. The elbow E is conveniently formed with a square shoulder e fitting a
square hole in the side of the tube A, and is internally screwed to admit the
screwed shank H of the air and drip chamber F.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. In a vaginal syringe, having a central air way in injection tube, and
detachably attached compression bulb, the construction of the said central air way
by a perforated shouldered nozzle at the point of the tube, and a perforated
shouldered elbow issuing laterally from side of tube, hermetically connected by a
flexible air-tube, to admit of any desired curvature or flexibility of the injection
tube and of the easy removal of central tube for cleansing, from a bent, flexible, or
other outer tube.
