A New or Improved Instrument for Extracting Particles of Foreign
Substances from the Eye.
We, WILLIAM BROWN, of 61, Claremont South Avenue, Engineer and GEORGE
ADIE, of 46, Bewick Road, Manager, both of Gateshead-upon-Tyne, in the County
of Durham, do hereby declare the nature of this invention to be as follows:-
This invention relates to an instrument by which small fragments of cinder,
metals, or similar foreign substances can be readily extracted from the eye
without danger of injury. In all works, especially in the engineering and kindred
trades, accidents from small particles or chippings of steel, iron, brass, copper,
or other foreign substances are of daily occurrence and in great numbers and
as a rule the head or point of a pin is used to pick out the particle, and this,
even when in the hands of a very expert operator, often leads to tearing the
outer portion of the eye, and sometimes serious injury is inflicted.
The instrument I propose to use consists of a small tube preferably of glass
with a smooth mouth nozzle, connected by a flexible tube to a mouthpiece to be
held between the lips of the operator.
The operator having this held between his lips has both hands free and having
examined the eye and found the position of the offending particle applies the
nozzle closely over it but not necessarily touching it and by suction draws it
into the nozzle. The nozzle and mouthpiece will preferably for cleanliness be
of glass and the tube of pure india rubber but any other suitable materials
may be used.

the same is to be performed to be particularly described and ascertained in and
by the following statement:-

In practice we have found this little instrument perfect in removing particles
from the eye, the sudden suction of the operator's lips and mouth invariably
drawing the offending particle into the enlarged portion of the tube, even, when
the nozzle is not quite in contact with the eye.
In large engineering works the foremen of the shops are often supplied with a
few of the instruments for the use of the workmen, and, some doctors may carry
one in their case of instruments.
DESCRIPTION OF DRAWING.
The accompanying drawing shews an instrument and its application to remove
a particle from the lower part of the pupil and from the upper part of the
eyeball to actual size.
so that it
A, is the nozzle preferably of glass slightly curved, with a perfectly smooth
mouth next the eye, and tapering to a larger tube at B, where a flexible tube 1),
is secured upon it by elastic friction, the other end of the tube being similarly
secured upon a mouthpiece C, also preferably of glass, and shaped
can be held firmly by the lips of the operator. The slightly curved end of the
nozzle when applied lengthwise has been found very well adapted to roll over
the upper eyelid and expose the ball of the eye before operating.
It will be obvious that though we prefer to furnish the instrument with a
flexible tube to give facilities for accurate adjustment to the eye, it may be :
in one piece from the nozzle A, to the mouthpiece C, of glass or other suitable
material.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
An instrument for extracting particles of foreign substances from the eve
by suction, which can be supported by the lips of the operator, leaving both
hands at liberty, consisting of a smooth mouthed nozzle to apply to the eye,
tapering to a larger size, preferably with a flexible tube between the nozzle and
a shaped mouthpiece for the lips of the operator; substantially as described and
shewn.
