Improvements in Vaginal Syringes.
A communication by WILLIAM VANDERBILT FOWLER, of 80 John Street, in
the City, County, and State of New York, United States of America,
Merchant, of the Firm of E. J. Hussey & Co., of the same place.
1, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of The Agency for
Foreign Patent Solicitors, 6 Lord Street Liverpool, and 6 Bank Street,
Manchester both in the County of Lancaster, 118 New Street, Birmingham in
the County of Warwick and 31 High Holborn in the County of Middlesex, Civil
Engineer, 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 the class of vaginal syringes, each of which comprises
a shield, a nozzle, an inlet nipple for the liquid connected with the nozzle, and a
drainage or outlet nipple, all rigidly connected together; and the object of the
invention is, in part, to provide against the formation of any crevices or joints
between the parts and thus avoid the collection of filth and germs not easily
removable by washing; in part to provide means for assuring the free outflow of
the waste liquid, and in part to certain novel features of construction and
combinations of parts which will be hereinafter described.
The accompanying drawings illustrate an embodiment of the invention.
Figure 1 is a perspective view of the syringe.
Figure 2 is a longitudinal, vertical section thereof.
Figure 3 is a face view with the nozzle in transverse section on line c, x, in
Fig. 2.
Figure 4 is a section of the nozzle in the plane indicated by line y, y, in
Fig. 3.
A represents the shield, preferably of vulcanized rubber, of oval configuration
when seen from the front as in Fig. 3, and curved or bow-shaped when seen in side
elevation, the outer face being somewhat convex.
From slightly above the center of the inner face of this shield projects the
nozzle B, at a slight upward inclination.
This nozzle is formed on the inner
face of the shield and is tubular. C is a nipple, formed on the outer face of
the shield, the bore thereof forming a continuation of that of the nozzle. The
nipple C provides a means for connecting the supply-pipe or tube to the
device.
The outer end of the nozzle B has ribs, D, between which are grooves or
channels, E, extending longitudinally of the nozzle. At the re-entering angles of
the grooves E are formed the forwardly inclined jet-passages F, as shown in
Fig. 4. The ribs D serve to expand the parts so that the liquid may escape freely
from the passages F, and the liquid is directed forward by the inclination of said
passages.
Along the underside of the nozzle B are two flauges, G. These flanges
commence at about the termination of the ribs D, and extend to and merge into
the shield A, flaring outward from each other somewhat, as indicated in Fig. 3.
Between these flanges is formed a chaunel H, which connects or merges into a
flaring outlet-passage, I, in the inner face of the shield, said outlet gradually
contracting and merging into the passage through a discharge nipple, J, to which
a waste-pipe or tube may be coupled at the outer face of the shield.

page_text: About the margin of the shield is fitted a tubular cushion and packing ring, N,
having a flap, O, which fits over the outer edge and face of the shield all around,
the tubular portion thereof being inside the plane of the shield; but at the
bottom of the shield the latter is provided with a lip, L, which is an inward
extension of the lower wall of the outlet passage I, and between the margin of this
lip and the lower edge of the shield is formed a concave groove or recess, M, in
which the tube of the packing ring rests at the lower, curved part of the shield.
The tension of the rubber holds the packing ring in place, but it may be readily
removed for cleansing.
In practice, the packing ring not only prevents leakage around the edges of the.
shield, but also prevents the injected liquid from coming in contact with any
portion of the exterior sensitive surfaces. This enables the user to employ very
hot water without feeling the heat unpleasantly.
Thus the device is especially desirable and is intended for use to allay
inflammation, or for medication, as by shuting off the outlet pipe, and by
pinching the tube, the liquid may be maintained within, without any appreciable,
pressure on the nozzle, without leakage and without allowing the liquid to reach
any exterior parts.
The purpose of the lip L and groove M, is to permit the liquid to flow out,
freely at the passage I and prevent the tubular part of the packing ring from
forming a dam to check the outward flow of the liquid to the discharge nipple.
The two flanges G along the underside of the nozzle B serve to spread and
hold back the parts and assure a free passage for the outflow of the waste-liquid ;
otherwise these soft parts would be liable to close in and close or choke the
passage.
Except as to the removable, soft rubber packing ring, the entire device, which
is integral and without joints, will be smooth, and preferably polished, so that it
may be readily cleansed or washed. The absence of joints and crevices enables
it to be cleaned without difficulty.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A jointless, vaginal syringe of smooth, hard material, comprising a shield, a
Dozzle with jet-apertures, an inlet nipple communicating with the nozzle, and an
outlet nipple for the waste-liquid, all rigidly and jointlessly connected, whereby the
formation of crevices for the collection of filth and germs is avoided and cleansing
facilitated, substantially as set forth.
2. In a syringe, the combination with the shield, having an outlet for the
waste-liquid, and a nozzle B, united in a rigid and jointless manner to the inner
face of said shield, of the two flanges G, along the underside of the nozzle and
adapted to hold back the adjacent parts so that they will not impede the outflow of
the waste-liquid, substantially as set forth.
3. In a syringe, the tubular nozzle B, having its outer end formed of
longitudinally extending ribs D, and having jet-apertures F, at the re-entering
angles between said ribs, said apertures being inclined forward, substantially as
set forth.
4. In a syringe, the combination with a smooth shield of hard material, of the
nozzle B, having ribs D at the end, separated by grooves E, and the jet-apertures D
situated at the base of said grooves, the inlet nipple C, the flanges G on the under
side of the nozzle and forming the channel leading to the discharge outlet, the
outlet, or discharge nipple J, the lip L, forming the lower wall of the flaring mouth
of the discharge outlet and the tubular ring of soft rubber detachably secured
about the edge of the shield, substantially as set forth.
5. In a syringe, the combination with a smooth, oval shield of hard material,
I,
provided with a nozzle, an inlet nipple, an outlet nipple, a flaring outlet passage
connecting with the outlet nipple, a lip L, forming an extension of the lower wall

page_text: of the passage I, and with a groove M, of the removable tubular, packing ring N,
of soft rubber provided with a flap O, said flap embracing the edge of the shield all
around and the tubular ring occupying the groove M, at the bottom of the shield,
substantially as and for the purposes set forth.
