PROVISIONAL SPECIFICATION.
An Improved Ear Syringe.
I, Sir WILLIAM BARTLETT DALBY, of 18 Savile Row, London, W., Fellow of
the Royal College of Surgeons, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object an improved ear syringe.
In syringing ears with an ordinary syringe the operation when undertaken by
an unskilled person is seldom effectually performed and sometimes injury is done.
The syringe which I have invented removes both these objections.
It has a nozzle with two passages through it one above the other; the first is for
the delivery of the jet of water or liquid into the ear and the second is to provide
a free passage for the liquid out from the ear.
The exterior of this nozzle is such that when inserted into the ear it fits it
closely as a plug so that it cannot be pushed too far and when the nozzle is in this
position the orifice by which the water or liquid is projected from the syringe is in
its proper position within the ear and lies parallel with the roof of the canal. The
passage forming the outlet enters the ear a letter distance.
The nozzle which I have described is most conveniently employed in connection
with the ordinary india rubber syringe bottle but it may be used with syringes of
any other sort.

COMPLETE SPECIFICATION.
An Improved Ear Syringe.
I, Sir WILLIAM BARTLETT DALBY, of 18 Savile Row, London, W., Fellow of
the Royal College of Surgeons, 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 for its object an improved ear syringe.
In syringing ears with an ordinary syringe the operation when undertaken by an
unskilled person is seldom effectually performed and sometimes injury is done. The
syringe which I have invented removes both these objections.
It has a nozzle with two passages through it one above the other; the first is for
the delivery of the jet of water or liquid into the ear and the second is to provide
a free passage for the liquid out from the ear.
The exterior of this nozzle is such that when inserted into the ear it fits it closely
as a plug so that it cannot be pushed too far and when the nozzle is in this position
the orifice by which the water or liquid is projected from the syringe is in its proper
position within the ear and lies parallel with the roof of the canal. The passage
forming the outlet enters the ear a lesser distance.
The nozzle which I have described is most conveniently employed in connection
with the ordinary india rubber syringe bottle but it may be used with syringes of
any other sort.
The drawing annexed shows in perspective an ear syringe in accordance with my
invention; the figure is about of the same size as the instrument.
a is the india rubber bottle, b is the nozzle, it may be of vulcanite or other
material. The nozzle has an orifice ¹ out of which when the bottle is squeezed a

page_text: stream of liquid is delivered. There is an enlargement on the side of the nozzle,
it. is tapered on the exterior and is of such dimensions as to fit the ear as a plug.
There is an outlet passage through the enlargement 2, the entrance to this passage
is at, and the exit at *. This passage allows the liquid employed to escape
freely from the ear.
In the use of the instrument the nozzle of the syringe is to be gently placed
in the ear as far as it will enter conveniently; the point of the nozzle is to be
kept uppermost. No further directions are necessary. The stream of liquid
issuing from the orifice cannot fail to pass along the roof of the canal and
consequently the ear is completely cleansed. The point of the nozzle cannot
enter too far and however unskilled the user, no injury can be done to the ear.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
