COMPLETE SPECIFICATION.
Improved Apparatus for Suction or Injection of Air or other Fluids
or Matters, principally for Surgical Purposes.
I, WARNERUS BORCHERS, Medical Practitioner of 4 Seiftstrasse Munich in
the Empire of Germany 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 :-
The object of this invention is principally to provide apparatus for removing
matters by suction whether gaseous such as air, gases or vapour, or liquid, or solid
matters such as may be made to flow and it is intended principally for the removal
of physiological or pathological fluids or liquids or such gases or foreign matters as
may be found or occur in various parts of the body.
The apparatus may be modified so as to be suitable also for injection for instance
in the place of irrigators or sprays, or, as required in many surgical operations
where puncturing and injection are alternately to be made.
The apparatus consists essentially as shown in Figure 1 of the annexed drawing
of two parts; first, an outer vessel a made of sheet metal and intended for boiling
purposes, being provided with a lid d hinged at s and provided with a pin m for
securing it; and second, a glass vessel, or flask, g of somewhat smaller dimensions
than the outer vessel a and intended to be placed therein, the said vessel
terminating above in a pipe r over which a flexible tube is stretched as shown at n,
this tube being provided with a clamp or compressor q for closing it, or with a cock
in place thereof as desired.

To use this apparatus a small quantity of water, or antiseptic solution, or in fact
any liquid which developes vapour on heating to be again condensed on cooling, is
placed in the flask g for instance to the height of about 1 centimeter. The flask is
then placed in the vessel a and the lid d closed the piper projecting through the
opening o. The vessel a is then filled with water through the opening o¹ in the lid
until nearly up to the edge. The water causes the vessel g to rise until it is
prevented from rising further by the lid d. Heat is then applied to the vessel a,
g is
for instance by placing it over a spirit lamp, until the liquid in the flask
converted into vapour filling the said vessel and expelling the air the compressor g
being loosened during this process. If now the compressor be closed and the
vessel suffered to cool the vapour in the flask g is condensed and forms a vacuum,
or so called vacuum in the flask g. The vessel is thus prepared for use as an
aspirator when desired, it being used by bringing the nozzle of the tube n into the
opening or place from which fluid or matter is to be drawn and loosening the
compressor 9 as required.
Figure 2 shows the apparatus so arranged as to be useful for injection as well as
suction. is a flask into which the pipe i projects nearly to the bottom this pipe
being connected by a tube n' with the branch tube v. The tube n' leads also to the
flask before described and serves also for the communication between the flask g
and the branch tube v. The branch tube may have a compressor q² for closing it,
and two compressors q' are severally arranged on the tube n' to close communication
with the flasks g and f respectively. Cocks may be used instead of compressors.
It is obvious that either flask g or f may be placed in communication with the
branch to the exclusion of the other, by loosening the respective compressor q¹
while the other is kept closed.
The flask is half filled with the desired liquid to be used as an injection spray or
otherwise and heat is applied to the air contained in the closed space above this
liquid, the air or vapours therein are expanded and brought under pressure ready

page_text: to force the liquid out at the pipe when the communication with the latter is
opened.
Where the apparatus is connected as described and shown in Figure 2 it is
sufficient in warming the flask g to allow the air driven from that flask to pass along
the tube n¹, the compressors q' being loosened, and thus enter the flask f providing
the extra air pressure desired therein.
The apparatus so prepared is then ready for use and may be employed with
facility for either injection or suction as may be required at the moment. Either
flask for g may however be used alone if desired.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1) An apparatus for suction of matter whether gaseous, such as, air gas or
vapour, liquid, or solid suitable to be extracted by such apparatus, the same
comprising an inner flask g with tube connected by flexible tube n with a suction
nozzle, and an outer vessel a intended to serve as a water bath for the flask g to be
heated to expel the air from said flask and to evaporate a liquid therein which upon
subsequent cooling and condensation provides a vacuum in said flask for the purposes
of.suction as described.
2) The combination of the aforesaid apparatus of a second flask connected to
the flask g by a pipe whereby the air or gases expelled from flask g enter the
flask to provide pressure upon liquid therein to act as in injector spray or the
like as described.
