Improvements in Syringes.
I, EUGENE TULLAH PEARL, of 23, Union Square, in the City and State of New
York, United States of America, Artist, 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: -
My invention relates to improvements in syringes.
The injection and suction type of syringe in general use for vaginal cleansing,
invariably discharges the water or other liquid in a solid column, varying from
to ¾ of an inch in diameter and when sudden or vigorous pressure is exerted in
compressing the bulb, the liquid is projected with such force as to frequently
cause injury of a more or less serious nature to the internal organs.
It is the object of the invention to produce a syringe, which in use, will be
entirely harmless and at the same time, highly effective in treatment. This I
accomplish by breaking up the solid column of liquid and spreading it in its
discharge, in the form of a whirling spray. The rotary motion imparted to the
liquid adapts it particularly to the peculiar requirements of vaginal cleansing, etc.,
and by thus lessening the direct force of discharge, all injurious effects are
thereby avoided.
The novelty of the invention lies in the construction and arrangement of a
series of inclined deflectors, which are radially disposed with respect to the axis
of the syringe nozzle or pipe and secured at or adjacent to the discharge end
thereof where they serve to separate the column of liquid into jets and to direct
these jets spirally, thus forming an approximately spherical spray, having a
decided whirling motion. The invention further consists in certain combinations
of elements to be hereinafter described and claimed.
In the accompanying drawings forming part of this specification, like reference
characters indicate similar parts throughout the several views, in which:-
Figure 1 is an elevation, partly in section, illustrating one embodiment of the
invention.
Figure 2 is a detail sectional view of the nozzle, illustrating diagramatically,
the discharge of the liquid therefrom, and
Figure 3 is an end view of the syringe, looking towards the discharge end
thereof, the cap being removed to show the deflector.
In these drawings,
1 represents the syringe, comprising a compressible bulb 2, a nozzle or pipe 3,
and a guard 4.
The bulb is of a form commonly employed, and is secured in the well known
manner by being forced over a terminal annular flange of the pipe.
5 represents a removable nozzle section, which is threaded into the pipe proper,
and provided with an annular groove 6, adjacent to its open end.
7 represents a liquid deflector seated in the groove of the removable nozzle
section, and consisting of a thin disk, preferably of metal, which is cut radially
at points equidistant throughout its circumference to provide a series of blades 8.
These blades are given a slight twist and thereby separated more or less, leaving

of the tube and through which the liquid, in passing, is deffected from its straight
course and discharged in spirally directed jets, which unite forming a hollow
whirling globe, as indicated by curved lines in Figure 2.
To avoid an injection of air, it is preferable in filling to remove the nozzle
section carrying the deflector and introduce the liquid with the syringe standing
upright, as in Figure 1, thereby displacing all of the contained air, The deflector
is then replaced and the device is ready for use.
To insure positively against leakage, a soft rubber cap 9, may be employed to
close the open end of the nozzle.
The bell-shaped guard 4 is adjustable along the tube and by its own resiliency
is self-sustaining at any point thereon. About mid-way of its length, it is
reduced in thickness and thereby rendered readily compressible in adapting
itself effectually as a closure against the escape of the liquid from the vaginal
passage. A reinforcing annulas 4", is formed in part with the guard and serves
to prevent undue compression or the collapse of the same.
In operation for cleansing the vaginal passage, the guard is adjusted to a point
near the outer end of the nozzle, and after the latter has been properly inserted,
the liquid may be injected and withdrawn by simply compressing and releasing
the bulb as many times as may be deemed advisable. For womb treatment, the
guard is adjusted to a point near the bulb to permit of the insertion of the
greater portion of the tube, thus bringing the discharge end into close proximity
to the mouth of the womb.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The combination with a syringe, of a deflector secured within the dis-
charge end of the nozzle and consisting of a disk having radial slits and the
portion between the slits bent at an angle to form wings, thereby affording spiral
passages between them, for the purpose specified.
2. The combination with a syringe, of a removable nozzle section and a deflector
secured within the discharge end of the nozzle, and consisting of a disk having
radial slits and the portion between the slits bent at an angle to form wings,
thereby affording spiral passages between them, for the purpose specified.
3. The combination with a syringe, of an approximately bell-shaped guard
adjustable upon the nozzle, a removable nozzle section and a deflector secured
within the removable section of the nozzle and consisting of a disk having radial
slits and the portion between the slits bent at an angle to form wings, thereby
affording spiral passages between them, for the purpose specified.
4. As an improved article of manufacture, the syringe herein described, con-
sisting of a soft rubber bulb, a rubber nozzle having its bore of uniform diameter
throughout, and a deflector fixedly secured within the discharge end of the
nozzle and consisting of a disk having radial slits and the portions between
the slits bent at an angle to form wings affording spiral passages between them,
with the central portion of the deflector imperforate and at right angles to the
bore of the nozzle, whereby the liquid is forced in an inclined direction through
the passages surrounding the central solid portion of the deflector and discharged
with a whirling motion uniform throughout the whole of the discharge end of
the nozzle, substantially as shown and described.
