GEORGE HOLLOWAY 45 Belgrave Road Birmingham Surgeon do hereby declare the
nature of this invention to be as follows:-
It consists of a tube of glass, or other material attached to an indiarubber ball;
pressure on which, supplies the power, (air in motion) which puffs out the powder.
To prevent the powder falling into the ball, the tube contains two curves, which make
the part between them, horizontal, & at right angles to the other parts of the same. On
this horizontal portion, the powder lies, and it contains an aperture for the insertion
of the said powder. The proximal curve, or the one nearest the ball, prevents the
contents of the tube from being easily shaken down into the ball, thus obviating the
necessity for a valve for that purpose. The tube is inserted and attached to the ball by
means of two nobs close together on the proximal portion of it. The first being pushed
through the indiarubber, prevents its being easily withdrawn. The second nob prevents
its being pushed in too far. The distal portion of tube is at right angles to the horizontal
portion and may be made in any length to reach any cavity.
It should be stated, that after the powder has been inserted, the aperture for its
insertion is closed either by a bit of indiarubber tubing being slided over it, or, which
is usually more convenient, by a finger being placed over it when in use,
The method of using it is as follows: The powder is inserted in the aperture in the
horizontal portion of the tube, which is closed by finger, or by indiarubber tubing
sliding over it. Pressure is applied to the ball, which sends a blast of air through the
tube, & expels powder into any place where the distal end of the tube may be directed.
As there is no valve to get fouled, or to take up room in the tube, the powder of course
gets the full benefit of the blast.

GEORGE HOLLOWAY 45 Belgrave Road Birmingham Surgeon 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 :-
It consists of a tube of glass, or other material, marked A in the drawing, attached
to a hollow indiarubber ball, marked B pressure on which, supplies the power (air in
motion) which puffs out the powder. To prevent the powder falling into the ball, the
tube is bent in two places, as shown in the drawing. On the portion of tube between
the angles C & D is an aperture, E, for the insertion of the powder, which lies in that
portion of tube, and is prevented from falling into the ball by the anglo C, thus obviating
the necessity of a valve for that purpose. The tube, is inserted, and attached to the
ball by means of two shoulders, F&G, near to each other on the proximal portion of
it, or the part nearest the ball. The shoulder is pushed through the indiarubber, and
prevents its being easily withdrawn. The shoulder G prevents its being pushed in too
far. The india rubber, binding upon the tube between the shoulders, is shewn in the
drawing. The distal portion of tube, D, H, is at an angle to the portion C, D, and
may be made in any length to reach any cavity. It should be stated that after the
powder has been inserted the aperture for its insertion, is closed, by a bit of indiarubber
tubing being slided over it, or, which is usually more convenient by a finger being
placed over it when in use.
The method of using the insufflator is as follows. The powder is inserted in the
aperture E, which is closed by the finger. Pressure is then applied to the ball B, which
sends a blast of air through the tube A, and expels the powder into any place where
the distal end of the tube may be directed. As there is no valve to get fouled, or to
take up room in the tube, the powder of course gets the full benefit of the blast.
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
That my Valveless Insufflator is substantially as described in the above statement,
and represented in the annexed drawings.
