LETTERS PATENT to Charles Henry Butlin, of Camborne in the County of
Cornwall, Surgeon, for an Invention of IMPROVEMENTS IN ENEMAS,

PROVISIONAL SPECIFICATION left by the said Charles Henry Butlin at

IMPROVEMENTS IN ENEMAS CATHETERS OR LIKE INSTRUMENTS FOR MAKING
SURGICAL INJECTIONS
"
My Invention has for its object to so construct the nozzle parts of Enemas,
Catheters, or like instruments for making surgical injections that a retention of
the fluid of injection is obtained.
According to my said Invention I affix at or towards the outlet orifice of the
instrument a flexible bag or its equivalent which extends some distance back over
the tube and is provided with a ring or other attachment to be held in the hand.
The instrument when in use is introduced in the ordinary way the tube being
held in one hand and the ring or attachment of the flexible bag in the other. The
tube is then retracted and the flexible bag forms a lining or retainer for preventing
backflow. The flexible material may be supplemented by strips of spring steel
and the fore part of the flexible material may be perforated to facilitate the
operation and the retention of the fluid.
A screw or fastening may be arranged so as to secure the flexible bag and tube
in their relative positions.
In cases where the nozzle of the instrument should not be retracted an additional
tube may be used to retract the flexible bag so as to prevent the necessity for
retracting the nozzle of the instrument.

"IMPROVEMENTS IN ENEMAS CATHETERS OR LIKE INSTRUMENTS FOR MAKING
SURGICAL INJECTIONS"
My Invention has for its object to provide the nozzle parts of enemas catheters
or like instruments for making surgical injections with means whereby a retention
of the fluid of injection is obtained.
According to my said Invention I affix at or near the outlet orifice of the
instrument a flexible bag or its equivalent which extends some distance back over
the tube and is provided with a ring or other attachment to be held in the hand.
The instrument when in use is introduced in the ordinary way the tube being
held in one hand and the ring or attachment of the flexible bag in the other.
By retraction of the tube or the bag the said bag forms a lining or retainer for
preventing back flow or escape of the fluid of injection.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed Sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 of the accompanying Drawing represents an enema arranged according
to my Invention. A is the part of the instrument by which the fluid of injection is
forced or pumped and B is the flexible tube leading to the nozzle part C. These
parts may be of any suitable kind, the essential features of my Invention being
quite independent of the kind of forcing or pumping apparatus employed. I have
merely illustrated one form of it to make the drawing complete, D is a flexible
bag surrounding the tube C of the nozzle part. The said bag may be attached in any
suitable way.
As shewn in the drawing its upper end is pinched between the end
of the tube C and the nipple c screwed therein, its lower end being secured between
the parts of the screw ring piece e, in which the tube C is capable of sliding.
When the parts are in the position shewn in full lines in the drawing the
instrument is inserted in the ordinary way. The tube C is then drawn back
whereby the bag D is caused to take the position indicated in dotted lines forming
a lining or retainer for preventing back flow of the fluid of injection. The parts
may be secured in position by screwing the ring e, upon a screw thread formed on
the tube C at c¹ or by any other suitable means.
The fore part of the bag D may be perforated as at d, to facilitate the operation
and retention of the fluid. If found advisable or necessary the flexible material
may be supplemented and strengthened by strips of very thin steel or the like but
if the bag be made of a sufficiently tough and strong material, these strips will
not be found necessary.
Figure 2 represents the application of the Invention to a catheter. The head f
of the catheter has a depressed part behind it to keep the upper part of the
attachment close to the head of the catheter. A tube g, is provided capable of
being slidden upon the catheter tube. The said tube g, may be of flexible material
strengthened by a metal strip or strips or it may be of any other suitable material.
To the front end of this tube, the front end of the bag D is attached. The
instrument is introduced with the parts in the position shewn in full lines and
then the tube g, is drawn back as indicated in dotted lines, the outer part of the
bag D being held in position by grasping the ring e, the catheter may then be

page_text: pushed forward as it will slide through the tube g, and flexible bag and at the
same time fluid may be injected. The bag D is shewn in its doubled position in
an exaggerated way to render the drawing clearer. The head f, may be perforated
instead of or in addition to the side as usual.
From the foregoing description, the general application of my Invention to
instruments for making Surgical injections will be readily understood.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is :-
Providing enemas, catheters, or instruments for making Surgical injections, with
a flexible bag or flexible attachment for acting as a lining or retainer for
preventing back flow or escape of the fluid of injection, substantially as
herein before described and illustrated by the examples shewn in the accompanying
drawings.
In witness whereof I the said Charles Henry Butlin have to this my
Specification set my hand and seal this 9th day of April One thousand eight
hundred and eighty four.
