Improvements in Syringes.
I, LETITIA MUMFORD GEER, of Number 2, East 118th Street, in the City of
New York, County and State of New York, U.S.A., Artist, do hereby declare.
the nature of this invention to be as follows:-
The piston rod is prolonged, and reflexed to form a handle which is approxi-
mately parallel with the piston rod, and so proportioned in length, and so
disposed, that the said handle will be within reach of the fingers of the hand
holding the cylinder of the syringe in the extreme positions of the piston. Or
the handle may be made separate from the piston rod in which case it would
be U-shaped in form, and have one arm shorter than the other, the short arm
being provided with means to attach it to the piston rod. The object of the
invention is to provide a syringe which can be operated with one hand; and is
especially valuable for rectal purposes as the operator can use it upon himself.
The end of the handle is provided with means to prevent the fingers slipping
off when in operation.

Improvements in Syringes.
I, LETITIA MUMFORD GEER, of No. 2, East 118th Street, in the City of New
York, County and State of New York, U.S.A., 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: -
1
This invention relates to improvements in syringes, and especially to that
class designed for rectal, and similar purposes; and has for its object to provide an
appliance of this character with a handle of peculiar and novel construction to
enable a person to use the same in injecting fluid into his own rectum without
the aid of an assistant.
I attain this object by employing the mechanism illustrated in the accompany-
ing drawings, in which
Figure 1 is a side view of my improved appliance illustrated partly in sectional
elevation, and showing two extreme positions of the piston and handle, and
Figure 2 is a similar view showing a slightly modified construction.
In the practice of my invention, I provide a syringe, having a piston-rod A,
.

page_text: with a handle which is substantially U-shaped in form, the same being bent at B,
to form two arms, A and C, which are extended parallel with each other. The
arm A, is connected at its inner end with the syringe piston, and the arm C, is
provided at the free end thereof with means to prevent the hand slipping off
the said arm when in use, preferably a hook extension D, but it is evident that
other means may be provided without departing from the spirit of my invention.
In Figure 1 of the drawings, the rod A and the arm C, are formed integrally,
but it is obvious that I am entitled to slight structural variations. For instance,
as shown in Figure 2, the piston-rod and handle C', are made separately and
connected to each other by means of the threaded socket E, forming part of
the loop B, and the threaded end G, formed on the piston-rod.
I have shown at E, the cylinder of an ordinary syringe, and at e, the discharge
nozzle, while a, represents the piston, to which the piston-rod A is secured.
The operation is as follows:-The operator inserts the nozzle in the rectum
while holding the cylinder E, it being understood that the syringe is first
charged with the liquid which it is desired to inject, and the handle is in the
position shown in full lines in Figure 1. When the nozzle is inserted in the
rectum, the operator can reach the handle, or the part C, thereof, with one or
more fingers of the same hand which holds the cylinder E, and as the extension D
will prevent the fingers slipping off the arm C, the said handle can be drawn
into the position shown in dotted lines in Figure 1, by the use of the one hand,
thereby enabling the operator to use the syringe upon himself without the aid of
an assistant, which would not be the case if it required two hands to operate the
syringe.
The device is very simple, and cheaply constructed, and it is evident that a
ring might be provided at the free end of the arm C, or any other well known
means to prevent the fingers slipping off said arm, and as the shape of the
handle may be varied to a certain extent without departing from the spirit of
my invention, I reserve the right to make any change which comes within the
scope of this invention.
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. In a hand syringe, the combination of a cylinder, a piston and an operating
rod which is bent upon itself to form a smooth and rigid arm terminating in a
handle, which in its extreme positions, is located within reach of the fingers of
the hand which holds the cylinder, thus permitting one hand to hold and operate
the syringe, substantially as shown and described.
2. In a hand syringe, the combination of a piston, a cylinder, a nozzle, and a
piston-rod having an arm secured thereto which extends approximately parallel
therewith towards the nozzle of the syringe, and has upon its free end an
extension for engaging the fingers of a person using the syringe, whereby the
appliance may be operated by use of one hand, substantially as shown and
described.
3. The combination with a syringe, of a handle extended toward the point of
ejection approximately parallel with the syringe piston-rod, and connected
thereto, the said handle having a projection on the free end thereof, substantially
as shown and described.
