An Improved Enema or Syringe.
I, CHARLES ALFRED TYRRELL, of 1562, Broadway, City of New York, in the
County of New York and State of New York, United States of America, Professor
of Hygiene, 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 has relation to that class of syringes in which a bag is employed
for holding the liquid to be injected. Other objects and advantages of the inven-
tion will appear from the following description, and claim, when taken in con-
nection with the annexed drawings.
In the said drawings, Figure 1 shows a perspective view of my improved syringe.
Figure 2, shows a view of the faucet, which forms a part of my improved syringe.
Figure 3, is a. view of the "injection point," otherwise known as a rectal pipe,
which is a special feature of my syringe. Figure 4, is a vertical, sectional view of
the said "injection point," or rectal pipe; and Figure 5, is a horizontal, cross
section view of the same. Figure 6, is a view of the brass fixture, which is in-
serted in one of the side walls of the bag, for the purpose of attaching the faucet
to the said bag.
In carrying out my invention, I take a bag, as in Figure 1, which may be of
the form usually employed, and made from rubber, or other suitable material.
This bag has a flaring, or funnel shaped mouth, which is closed with a screw
stopper A, and is also furnished with a perforated tab, B, at the opposite end, by
which, it may be suspended from a nail for a purpose to be hereafter described.
In one of the side walls of the bag, c and, preferably, in the centre, a brass fixture,
Figure 6, is inserted-screw tapped, as shown, for the attachment of the faucet,
Fig. 2. The said faucet is also screw tapped, on the under side, to connect with
the brass fixture, and on its upper side, to receive the "injection point," or rectal
pipe D which is also screw tapped. The bag also has a strap, E, at the mouth,
or filling aperture.
The bag, as is customary in the manufacture, is made so that the side walls will
collapse, when the liquid is discharged, and will inflate, when the bag has been
filled.
"
By this description it will be seen that when the bag has been filled, and is to be
used as a rectal syringe, which is its principal purpose, the "injection point,'
or rectal pipe, is screwed into the faucet, which is attached to the side wall of the
bag. The person, taking the injection, thus inserts the "injection point," or rectal
pipe in the anus, and sits easily, and firmly on the bag, when the weight of the
body injects the fluid. The injection can be controlled by means of the faucet,
the handle, or key, of which, projects forward, between the limbs of the person
seated on the bag. The dome shape of the faucet is specially designed to fill the
arch, formed by the body, when in a sitting posture, and thus give support, and
prevent prolapse of the viscera.
Although it is mainly designed as a rectal syringe, yet, without any alteration

page_text: on, it may be used as a hot water bottle, by shutting off the fauce
filling the bag with hot water, and closing it, at the mouth, with the scre
stopper, A.; or, by inserting a specially made stopper, with a flexible rubber tub
attached, and suspending it from a nail, by the tab, B, it may be used as
fountain syringe.
The "injection point," or rectal pipe, which is made of hard rubber, but may
be made of other material, is constructed of the same diameter, for two thirds o
its length, the remaining portion of its length, consisting of a constricted portion
or neck, a shoulder, and a screw tapped portion, to connect it with the faucet
The bulbous portion is provided with numerous rows of perforations, through
which, the fluid is injected.
The objects of this method of construction, are, as follows--Firstly, to prevent
the escape of the fluid from the rectum, while using it as a rectal syringe, by
allowing the lower sphincter muscle to close around the constricted portion, or
neck-thus completely preventing any return of said fluid, and, secondly, by
means of the said rows of perforations, to enable the fluid to come into immediate
contact with the walls of the rectum, instead of being discharged beyond the
hemorrhoidal region, as is the case in all previously existing appliances. Thirdly,
by constructing the extreme point, or tip of said "injection point," or rectal
pipe, of solid material, all danger of injuring the mucous membrane, by the con-
tinuous action of a direct jet of water, or other fluid, on one spot, is completely
obviated. Figure 3, in the accompanying drawings, shows the said "injection
point," or rectal pipe D indicating the perforated, bulbous portion, D¹ the con-
stricted portion, or neck, and D the solid point or tip, all as previously described.
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. A syringe, consisting of a "compressible water bag, or holder, which is
operated by the user being seated upon it, the personal weight of the user fur-
nishing the motive power to inject the fluid, substantially as specified.
2. As an improved article of manufacture, a syringe, consisting of a compres-
sible water bag, or holder, a faucet specially constructed to fit the natural arch of
the body when in a sitting posture, and an "injection point" or rectal pipe,
constructed to prevent the escape of fluid from the body and to bring the injected
Quid into immediate contact with the walls of the rectum, substantially as 3
pecified.
