I, JOSEPH ACHARD-MILHET of 73 Rue de l'hôtel de ville, Lyon, in the Republic
of France, Manufacturer, do hereby declare the nature of this invention, to be as
follows:-
This invention has for its object the application of compressed air for truss cushions
and for the cushions of other compressing apparatus used in the practice of surgery
or medicine, so as to allow the pressure and the swelling to be increased or diminished
by means of a very simple and portable apparatus.
As applied to trusses the apparatus consists of two metal back-plates placed on each
other and provided with a hole for the passage of a valve, a bladder or cushion of
caoutchouc, a wash leather or other covering for the said bladder and a metal valve
for the introduction and removal of air.
The valve consists of a semicircular outer casing adapted to pass through the plates
above mentioned and having a screw-thread on which moves a nut by which it may be
clamped or held firmly.
The part terminating in the caoutchouc bladder is provided with a hole for the
passage
of air and has inside a small washer of caoutchouc or leather. This outer
part is provided with an interior screw thread and receives a correspondingly threaded
tube having above a conical extension adapted to close the orifice in the outer casing.
The bore of the tube terminates in a hole communicating with the interior of the
casing.
By unscrewing the interior plug, the orifice is opened, and the air escapes from the
bladder. By means of a set screw inserted in the outer casing the course of the conical
plug is regulated so as not to exceed an half turn.

page_text: The cushion is given the desired tension by means of an air forcing apparatus, the
nozzle of which is introduced into the plug. On each side of the said nozzle are
arranged projecting pins which catch into recesses arranged on the plug, so that by
turning the air forcer so as to unscrew the plug, the valve is opened to admit air and
by a contrary turning of the forcer, the valve is closed.

Medical Compressing Apparatus.
I, JOSEPH ACHARD-MILHET, of 73 Rue de l'hôtel de ville, Lyons, in the Republic of
France, Manufacturer, 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 the application of compressed air for truss cushions
and for the cushions of other compressing apparatus used in the practice of surgery
or the like, so as to allow the pressure and the swelling of the cushions to be increased
or diminished by means of a simple and portable apparatus.
The accompanying drawing shows the invention as applied to trusses.
The apparatus consists of two superposed metal back plates A and B Fig. 2
provided with a hole for the passage of a valve, a bladder or cushion of caoutchouc C,
a wash leather or other covering O for the said bladder and a metal valve for the
introduction and removal of air."
The valve, Fig. 1. consists of a cylindrical outer part E having an enlarged head
and adapted to pass through the plates A and B above mentioned, so that the flange of
said head abuts thereon. The cylindrical portion of this sleeve is screw-threaded
within and without and carries on the outer screw thread the nut D, by which it may
be clamped or held firmly.
The head terminating in the caoutchouc bladder C is provided with a hole I for the
passage of air and has inside a small washer J of caoutchouc or leather. This outer
part E receives a correspondingly threaded tube F having above a conical extension
adapted to close the orifice in the outer casing. The bore of the tube E is open at G

page_text: and communicates with the interior of the outer casing E. The tube F terminates in
a disc having two notches K K. The course of the tube F can be regulated by means
of a little set screw H.
When the orifice I Fig. 1 is closed by the conical head of the tube F abutting on
the washer or disc J, the air contained in the caoutchouc bladder C cannot escape.
By unscrewing the interior tube F, the orifice I is opened and the air escapes from
the bladder. The cushion is given the desired tension by means of an air forcing
apparatus N, the nozzle L of which is introduced into the opening G of the plug F.
On each side of the said nozzle are arranged projecting pins M which catch into the
recesses K arranged in the plug F so that by turning the air forcer so as to unscrew
the plug, the valve is opened to admit air and by a contrary turning of the forcer, the
valve is closed.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
In cushions of trusses and other surgical appliances
1) The combination with a suitable backing A B of a receptacle C of air proof
material substantially as and for the purpose set forth.
2) The combination with the cushion C of the herein described valve and air forcer
adapted to open and close said valve as set forth.
Dave is 14th day of November 001.
